  Some side grooves include, for example, a plurality of side groove blocks that are connected in at least two directions so as to have different angles depending on the water collecting block. In such a side groove, for example, a rectangular tube-shaped, typically flat, cubical water-collecting member as in Patent Document 1 is used as a water-collecting-basket block or a meeting-house-basket block.

  FIG. 17 is a plan view (top view) showing an example of the side groove. In the side groove system 91 shown in FIG. 17, the three-direction side grooves 92 a, 92 b, and 92 c constructed by the plurality of side groove blocks 90 are connected by the water collecting tank block 110. In this example, side grooves 92 b and 92 c constructed along a road boundary, for example, a boundary 105 between the road 101 and private land (private land) 102 are connected to a side groove 92 a constructed so as to cross the road 101. is doing.

  FIG. 18 shows the side groove system 91 in a cross-sectional view of the relationship between the side groove block 90 and the water collecting basin block 110 as viewed from the direction of the side groove block 90. FIG. 19 is a longitudinal sectional view of the water collecting basin block 110, and FIG. 20 is a cross-sectional view of the water collecting basin block 110 cut along a plane parallel to the bottom surface. As shown in FIG. 18, the side groove block 90 in this example is a gate-shaped concrete block having an open bottom called a free gradient side groove for forming a water channel 96 having a width W9 therein. The bottom surface 95 of the side groove block 90 is constructed by the invert concrete 95a after the height of the side groove block 90 is adjusted by the foundation concrete 109 at the construction site.

  The side groove block 90 includes side walls 97 on both sides and an upper wall portion 98 that connects the upper sides of the side walls 97 and constitutes the ceiling portion of the water channel 96. The center of the upper wall portion 98 is an opening (opening portion) 98a so that a concrete lid 99 or a grating lid can be mounted. On the other hand, both ends of the upper wall portion 98 are culvert portions (slab portions). The upper portion 97a of the side wall 97 has a shape that projects outward to form an L-shaped lid receiver 97c on which the lid 99 is placed. By projecting the upper portion 97a of the side wall 97 to the outside, the lid receiver 97c is positioned on the lower portion (base) 97b of the side wall so that the load of the lid 99 is easily received. In the side groove block 90 in which the upper portion 97a of the side wall 97 extends outward, the width W8 of the upper wall portion 98 is considerably longer than the width W9 of the water channel 96.

  The water collecting basin block 110 is a concrete block having a square shape when viewed from above and is basically surrounded by side walls 117 like a ridge. In this example, like the side groove block 90, the block is provided as a block with the bottom surface 115 opened. At the construction site, the bottom surface 115 is constructed by the invert concrete 115a after the height of the side groove block 90 and the like is adjusted by the foundation concrete 109.

  In the water collecting basin block 110 in this example, a water channel 116 having a width W9 that passes through the side walls 117 and communicates with the side grooves 92a to 92c is formed in the three side walls 117 of the four side walls 117. . The upper portion 117a of each side wall 117 becomes an L-shaped lid receiver 117c, and a grating lid 119 is installed. The width L8 of each side wall 117 (the length of one side of the drainage trap block) L8 matches the width W8 of the upper wall portion 98 of the side groove block 90. This type of water collecting block 110 can sufficiently secure the wall thickness of the side wall 117. Therefore, as shown in FIG. 20, even when the water channel 116 that penetrates the three side walls 117 is formed, the cross-sectional area of the side walls 117 can be secured and the strength can be maintained.

  2. Description of the Related Art In recent years, as a side groove block, a side groove block has been provided in which an outer surface of a side wall has no portion projecting to the outside and extends substantially straight (flat) in a vertical direction. A typical example of such a type (outside straight type) side groove block is different from the above-described type (outside protruding type) side groove block 90, and a lid holder for placing a lid is projected inside the side wall. It is the block for side grooves formed by this.

  FIG. 21 is a plan view showing an example of the side groove system 121 constructed using the outer straight type side groove block 80 and the water collecting block 110 described above. In the side groove system 121 shown in FIG. 21, the three-direction side grooves 82 a, 82 b, and 82 c constructed by a plurality of side groove blocks 80 are connected by the water collecting tank block 110. In this example, side grooves 82 b and 82 c constructed along a road boundary, for example, a boundary 105 between the road 101 and private land (private land) 102 are connected to a side groove 82 a constructed so as to cross the road 101. is doing.

  FIG. 22 shows the side groove system 121 in a cross-sectional view of the relationship between the side groove block 80 and the water collecting basin block 110 as viewed from the direction of the side groove block 80. The side groove block 80 in this example is also a gate-shaped concrete block having an open bottom called a free-gradient side groove for forming a water channel 86 having a width W9. The bottom surface 85 of the side groove block 80 is constructed with invert concrete 85a after the height of the side groove block 80 is adjusted by the foundation concrete 109 at the construction site.

  The side groove block 80 includes side walls 87 on both sides and an upper wall portion 88 that connects the upper sides of the side walls 87 and constitutes the ceiling portion of the water channel 86. The center of the upper wall portion 88 is an opening (opening portion) 88a so that a concrete lid 89 or a grating lid can be mounted. Both ends (both ends in the longitudinal direction) of the upper wall portion 88 are slab portions (dark culvert portions). The upper portion 87 a of the side wall 87 has a shape that protrudes inward to constitute an L-shaped lid receiver 87 c on which the lid 89 is placed. In this type of side groove block 80, the width W7 of the upper wall portion 88 for forming the water channel 86 having the same width W9 as that of the different type of side groove block 90 can be reduced.

  Therefore, in the system 121 combined with the water collecting basin block 110, the width W7 of the side groove block 80 is narrower than the length L8 of one side of the water collecting basin block 110. For this reason, if the catchment block 110 is arranged in alignment with the boundary 105 between the road 101 and the private land 102, a gap G is formed between the side groove block 80 and the boundary 105. The boundary 105 between the road 101 and the private land 102 such as a house is often composed of a concrete structure such as a retaining wall, and when such a gap G occurs, it takes time and effort to process the gap G. Sometimes. The gap G is a dead space. Therefore, by using the side groove block 80, although the width W7 of the side grooves 82b and 82c for securing the same water channel width W9 can be reduced, the occurrence of dead space reduces the merit of the side groove block 80 by half. To do.

  FIG. 23 and FIG. 24 are an example of a drainage basin block 130 having a side length L7 that matches the width W7 of the side groove block 80. FIG. The water collecting basin block 130 is a concrete block having a square shape when viewed from above and is basically surrounded by side walls 137 in four directions like a ridge. In this example, like the side groove block 80, the block is provided as a block with the bottom surface 135 opened. At the construction site, the height of the side groove block 80 and the like is adjusted by the basic concrete 109, and then the bottom surface 135 is constructed by the invert concrete 135a.

  In the water collecting basin block 130 in this example, a water channel 136 having a width W9 that passes through the side walls 137 and communicates with the side grooves 82a to 82c is formed in the three side walls 137 of the four side walls 137. An upper portion 137a of each side wall 137 becomes an L-shaped lid receiver 137c projecting inward, and a grating lid 139 is installed. The width L7 of each side wall 137 (the length of one side of the water collecting block 130) L7 matches the width W7 of the upper wall portion 88 of the side groove block 80. This type of water collecting block 130 cannot secure a sufficient wall thickness of the side wall 137. Therefore, as shown in FIG. 24, when the water channel 136 that penetrates the three side walls 137 is formed, the cross-sectional area of the remaining part of the side wall 137 becomes very small and the strength cannot be maintained. For example, when the wall thickness of the drainage trap block is ½, the cross-sectional area of the leg portion of the corner (corner), that is, the corner portion where the water channel is formed on two adjacent sides is It becomes 1/4 and the strength is greatly reduced.

  Furthermore, as shown in FIG. 23, since the lid receiver 137c has a shape projecting inward, the opening for maintaining the water collecting basin becomes small. The catchment basin is a part where dirt, mud and the like are easily collected, and is also used to collect and remove the dirt and mud. Therefore, securing a wide opening is important in the catchment block.

  One aspect of the present invention is a concrete drainage block that can connect a plurality of side groove blocks in at least two directions at different angles, and includes first to fourth side walls arranged in four directions. It is a drainage drainage block having a bottom portion opened and a lid receiver provided on the upper portion. The first to third side walls can be stamped such that at least one of the first to third side walls forms a water channel that passes through the at least one side wall, or a water channel is formed. ing. That is, at least one of the first to third side walls is formed with a water channel in advance or is a knock-out type side wall capable of forming a water channel. On the other hand, the fourth side wall is thicker than the first to third side walls, and a water channel penetrating the side wall is formed in advance.

  The drainage basin block included in the present invention first has a fourth side wall that is thicker than the first to third sidewalls, and is different from the above-described basin drainage block in a shape to be rotated by 90 degrees. Not. By increasing the thickness of the fourth side wall, the strength of the water collecting block can be secured. Further, by thickening only the fourth side wall, the water channel perpendicular to the water channel penetrating the fourth side wall can be opened at an eccentric position (offset position), and the side groove block can be connected at the eccentric position. . For this reason, when constructing a gutter system along a boundary, it can control that a crevice arises between a boundary and a block for gutters.

Further, the water collecting block has a lid receiving frame formed of an L-shaped member in order to install a grating lid on the upper part. The lid receiving frame is mounted on the first to third side walls so that the outer peripheral surface of the lid receiving frame substantially coincides with the outer peripheral surfaces of the first to third side walls and the three sides of the lid receiving frame are exposed. Then, the other side of the lid receiving frame is mounted on the inner upper portion of the fourth side wall. Typically,
The wall thickness of the first to third side walls is approximately equal to the width of one side of the lid receiving frame. Further, it is desirable that the outer upper portion of the fourth side wall is a concrete slab (Slab) portion reaching almost the upper end of the lid receiving frame.

  Since the strength can be ensured by increasing the thickness of the fourth side wall, the first to third side walls can be made thin, and the wall thickness can be made substantially equal to the width (frame width) of one side of the lid receiving frame. Furthermore, by mounting the cover receiving frame on the first to third side walls so that the three sides are exposed, the problem that the thickness of the concrete covering the cover receiving frame cannot be secured can be avoided. That is, if the side of the lid receiving frame is covered with concrete, a thickness of at least several centimeters is required to prevent peeling off, and the wall thickness cannot be reduced, or an opening area surrounded by the lid receiving frame is secured. There was a problem of being unable to do so. These problems can be avoided by exposing the lid receiving frame.

  On the other hand, since the fourth side wall is thick, another side of the lid receiving frame is mounted on the inner upper side of the side wall, and the outer upper side of the side wall is a concrete slab portion (dark culvert structure) reaching almost the upper end of the lid receiving frame. By doing so, the strength can be secured.

  In the first to third side walls, the upper ends of the three sides of the lid receiving frame are aligned with the upper ends of the side groove blocks connected to the water catchment block, and in the fourth side wall, It is desirable that the upper end of the slab portion is aligned with the upper end of another side groove block connected to the water collecting block. The side groove block can be connected to each of the first to fourth side walls without a step (with few steps).

  The outer surface of each of the first to third side walls may extend substantially flat in the vertical direction, and by combining with the outer straight type side groove block, it is possible to construct a side groove system in which a gap with the land boundary is less likely to occur.

  On the upper surface of the slab portion, a pattern that is continuous with the upper surface of the culvert portion of the side groove block connected to the drainage trap block, for example, a grid pattern or a lattice pattern, can be applied. The slab portion of the fourth side wall has a common pattern with the side groove block to be connected, and the edge of the lid receiving frame is only slightly visible at the connection portion between the first to third side walls and the side groove block. . Therefore, it is possible to construct a side groove system in which the side groove block and the water catchment block are visually grouped.

  Another aspect of the present invention is the above-described water collecting basin block and the first side groove block connected to the fourth side wall of the water collecting basin block, which is equal to the width of the fourth side wall. A first side groove block having a width and a second side groove block connected to the first side wall perpendicular to the fourth side wall of the drainage trough block, the width being equal to the first side groove block And a second side groove block.

  Using the drainage block included in the present invention, the first side groove block is connected to the fourth side wall of the drainage block so as to bend in the direction of 90 degrees, and the second side groove block is collected. A gutter system connected to the first side wall adjacent to the fourth side wall of the water tank block can be constructed. Furthermore, by connecting the third gutter block to the third side wall facing the first side wall of the catchment basin, a gutter system in which the side gutters are combined in a T shape can be constructed, and along the land boundary. Thus, the second and third side groove blocks and the catchment block can be arranged so that a gap is not easily generated. It is preferable that the side groove block is a gate-type side groove block, and the outside of both side walls is substantially flat.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a water collecting water block (house office wall block) 10 according to an embodiment of the present invention. FIG. 2 is a perspective view showing a state in which the grating lid 40 is installed on the lid receiving frame 30 of the water collecting block 10. 3 is a plan view (top view) of the catchment block 10, FIG. 4 is a bottom view of the catchment block 10, and FIG. 5 is a front view of the catchment block 10. is there. FIG. 6 is a side view (right side view) of the water collecting basin block 10, and the left side view of the water basin block 10 is symmetrical to the right side view shown in FIG. FIG. 7 is a cross-sectional view of the drainage basin block 10 taken along the line VII-VII in FIG. FIG. 8 is a cross-sectional view of the water collecting block 10 taken along the line VIII-VIII in FIG. Further, FIG. 9 is a rear view of the catchment block 10.

  This water collecting block 10 is basically made of concrete and is prefabricated (precast) in a factory, and is made of concrete capable of connecting a plurality of side groove blocks in at least two directions at different angles. Catchment block. This catchment block is typically used with a gutter block to construct a gutter system for discharging rainwater, domestic wastewater, etc. along a road, sidewalk, or the like.

  The drainage block 10 has a first side wall 11, a second side wall 12, a third side wall 13, and a fourth side wall 14 arranged in four directions. In the drainage block of this example, the first side wall 11 and the third side wall 13 are opposed side walls, and are side walls adjacent to the fourth side wall 14. Further, the second side wall 12 and the fourth side wall 14 face each other. In the drainage block 10, the outer surfaces 11a to 13a of the first to third side walls 11 to 13 are provided with knockout recesses 29 as described later, but as a whole flat in the vertical direction. It is formed to spread.

  The water collecting block 10 includes a main body portion 20 made of concrete and a metal lid receiving frame 30 attached (embedded) on the upper portion of the main body portion 20. Although the bottom portion 25 of the main body portion 20 is open, a bottom surface is constructed by invert concrete at the site, and a meeting place (water channel) 26 is formed inside the main body portion 20. Therefore, the water collecting basin block 10 is a block suitable for constructing a meeting place for connecting a side groove block called a variable gradient side groove. The lid receiving frame 30 is formed of a metal member having an L-shaped cross section (for example, an L-shaped channel made of stainless steel, an L-shaped channel plated with zinc, or the like) in order to install the grating lid 40.

  In the water collecting basin block 10 of this example, a dent 29 for knockout is provided on all of the first to third side walls 11 to 13. For this reason, by punching the side walls 11 to 13 along the dent 29 at the site, an arch-type water channel that penetrates the respective side walls 11 to 13 and reaches the hall 26 can be formed. That is, each of the first to third side walls 11 to 13 includes a punched portion for forming an arch-shaped water channel.

  On the other hand, as shown in FIGS. 4, 7, and 8, the fourth side wall 14 has a wall thickness t <b> 4 larger than the wall thicknesses t <b> 1 to t <b> 3 of the first to third side walls 11 to 13, and the fourth side wall 14. In advance, an arch-shaped water channel 24 penetrating the side wall 14 is formed. Typically, in the case of a drainage basin block 10 for connecting a gutter block forming a water channel having a width W9 of 300 mm, the wall thicknesses t1 to t3 of the first to third side walls are The wall thickness t4 of the fourth side wall is 160 mm, and the wall thickness t4 of the fourth side wall is designed to be approximately 2.5 times the wall thickness t1 to t3 of the other side walls. . The wall thickness t4 of the fourth side wall is desirably about 2 to 3 times the wall thicknesses t1 to t3 of the other side walls.

  Accordingly, the water collecting block 10 has a wall thickness t4 of the fourth side wall 14 that is thicker than the wall thicknesses t1 to t3 of the first to third side walls 11 to 13, and is not in a shape to be rotated by 90 degrees. . In other words, the drainage block 10 has a length L1 in the direction of the fourth side wall 14 and the second side wall 12 with respect to a length L2 in the direction of the first side wall 11 and the third side wall 13. long. Typically, in a water collecting block suitable for the side groove block 50 having a water channel width W9 of 300 mm, the length L1 is 520 mm and the length L2 is 420 mm.

  The lid receiving frame 30 mounted on the upper part of the concrete main body 20 is a square frame made of a metal member having an L-shaped cross section, and has four sides 31 to 34. The lid receiving frame 30 includes an outer peripheral wall 35 extending in the vertical direction and a receiving wall 36 extending inward in the horizontal direction from the outer peripheral wall 35, and the metal grating lid 40 is formed by the outer peripheral wall 35 and the receiving wall 36. It can be supported. The width of the receiving wall 36 of the lid receiving frame 30 is substantially the same as the wall thickness t1 to t3 of the first to third side walls, and the lid receiving frame 30 has the width of the first to third side walls 11 to 13. The outer peripheral surface 37 of the outer peripheral wall 35 of the lid receiving frame 30 is mounted so as to substantially coincide with the outer peripheral surfaces 11a to 13a of the first to third side walls 11 to 13. Therefore, the three sides 31 to 33 of the lid receiving frame 30 are mounted on the concrete main body 20 so that the metal outer peripheral surface 37 is exposed.

  On the other hand, the remaining side 34 of the lid receiving frame 30 is mounted on the inner upper part of the fourth side wall 14, and the outer upper part of the fourth side wall 14 is a concrete slab part that reaches almost the upper end of the lid receiving frame 30. 21. The upper surface 21a of the slab part 21 is provided with a pattern 22 connected to an upper surface 58a of a culvert part 58 of a side groove block 50 described later. In this example, the center 42 is slightly recessed with respect to both ends 41 of the upper surface 21 a, and a grid-like pattern 22 is provided on the recessed surface of the center 42.

  In such a water catchment block 10, in the first to third side walls 11 to 13, the side grooves in which the upper ends 38 of the three sides 31 to 33 of the lid receiving frame 30 are connected to the water catchment block 10. The upper end of the block 50 (the upper surface of the culvert portion 58) 58a can be adjusted. Further, the upper end (upper surface) 21 a of the slab portion 21 is aligned with the upper end 58 a of the side groove block 50 in the fourth side wall 14 of the drainage trap block 10.

  FIG. 10 is a perspective view showing a state in which the knockout dent 29 in the first side wall 11 of the drainage trap block 10 and the knockout dent 29 in the third side wall 13 are punched out at the construction site. FIG. 11 is a perspective view showing a state in which the grating lid 40 is installed on the lid receiving frame 30 of the block (hereinafter referred to as the construction water collecting block) 10a in which the knockout hole 29 of the water collecting block 10 in FIG. 10 is punched out. This is shown in the figure. FIG. 12 is a sectional view of the water collecting basin block 10a in a construction state cut along a plane parallel to the bottom surface and viewed upward.

  The water collecting block 10a in the construction state includes a water channel 28 that passes through the side walls 11 and 13 and reaches the meeting place 26, and a water channel 24 that passes through the side wall 14 and reaches the place 26. Therefore, the side groove block 50 can be connected to the three sides of the side walls 11, 13, and 14, and a side groove system in which the three-direction side grooves intersect with each other in a T-shape can be constructed so that the angles are different by 90 degrees. It is also possible to form a water collecting block for construction in different states by punching out one knockout hole 29 of the side wall 11 or 13 by the water collecting block 10, and in two directions so that the angle is different by 90 degrees. A side groove system in which the side grooves intersect in an L shape can be constructed.

Can be constructed. Furthermore, it is possible to form the water collecting basin block 10a for construction in a different state in which the knockout hole 29 of the side wall 12 is punched out by the water collecting basin block 10, and a water collecting basin is provided in the middle of the side groove. The installed gutter system can be constructed.

  FIG. 13 is a plan view showing an example of the side groove system 1 constructed using the outer straight type side groove block 50 and the construction drainage block 10a. In the side groove system 1 shown in FIG. 13, the three-direction side grooves 2a, 2b, and 2c constructed by the plurality of side groove blocks 50 are connected by the water collecting tank block 10a. In this example, the side grooves 2b and 2c constructed along the road boundary, for example, the boundary 105 between the road 101 and the private land (private land) 102 are connected to the side groove 2a constructed so as to cross the road 101. is doing.

  FIG. 14 shows the side groove system 1 in a cross-sectional view of the relationship between the side groove block 50 and the catchment block 10a as viewed from the side groove block 50 of the side groove 2b. FIG. 15 shows a relationship between the side groove block 50 and the water collecting basin block 10a by a cross-sectional view of a connecting portion between the side groove 2a and the water collecting basin block 10a. The side groove block 50 in this example is also a gate-shaped concrete block having an open bottom called a free-gradient side groove for forming a water channel 56 having a width W9. The bottom surface 55 of the side groove block 50 is constructed with invert concrete 55a after the height of the side groove block 50 is adjusted by the foundation concrete 109 at the construction site. At the same time, the bottom surface 25 of the water collecting basin block 10a is also constructed by invert concrete 25a.

  The side groove block 50 includes side walls 57 on both sides and an upper wall portion 53 that connects the upper sides of the side walls 57 and constitutes the ceiling of the water channel 56. The center of the upper wall portion 53 is an opening (opening portion) 52 so that a concrete lid 59 or a grating lid can be mounted. Both ends of the upper wall portion 53 in the longitudinal direction are slab portions (dark culvert portions) 58, and a pattern 54 is provided on the upper surface 58a. In this side groove block 50, the entire upper surface of the upper wall portion 53 has a shape in which the center 42 is recessed with respect to both ends 41 in the width direction (short direction), and a grid-like pattern 54 is attached to the center 42. Has been.

  The upper portion 57a of the side wall 57 of the side groove block 50 has a shape that projects inward to form an L-shaped lid receiver 57c on which the lid 59 is placed. This side groove block 50 is an outer straight type side groove block similar to the side groove block 80 described with reference to FIGS. 21 and 22, and forms a water channel 56 having the same width W9 as the outer overhang type side groove block 90. The width W7 of the slab part 58 can be narrowed.

  In the water collecting block 10, the wall thickness t4 of the fourth side wall 14 is thicker than the wall thicknesses t1 to t3 of the first to third side walls 11 to 13, and is not in a shape to be rotated 90 degrees. The drainage block 10 has a length L1 in the direction of the fourth side wall 14 and the second side wall 12 that is longer than a length L2 in the direction of the first side wall 11 and the third side wall 13. Further, by increasing the thickness of the fourth side wall 14, it is possible to secure the strength of the water collecting basin block 10a in a construction state in which at least one knock-out hole 29 of the first to third side walls 11 to 13 is punched out.

  In this way, the water collecting basin block 10 increases only the wall thickness t4 of the fourth side wall 14 to increase the water channel orthogonal to the water channel 24 penetrating the fourth side wall 14, that is, the first side wall 11. And the water channel 28 formed by punching out the knockout hole 29 of the third side wall 13 can be opened at a position eccentric (relative position) with respect to the longitudinal direction L1. In this example, the length (the length in the width direction of the fourth side wall 14 and the second side wall 12) L2 in the direction orthogonal to the longitudinal direction (length L1) of the water collecting block 10 is set to the side groove block. 50 width W7. Further, when the positions of the knockout holes 29 in the first side wall 11 and the third side wall 13 are aligned with the outer surface 12a of the second side wall 12 and the outer surface of the side wall 57 of the side groove block 50, the side groove block It arrange | positions so that it may correspond with the position of 50 water channels 56. FIG.

  That is, the wall thicknesses t1 to t3 of the first to third side walls 11 to 13 of the water collecting block 10 are designed to be the same as the wall thickness of the side wall 57 of the side groove block 50. Furthermore, the length L2 in the short direction of the water collecting basin block 10 is designed to be the same as the width W7 of the side groove block 50, and the side wall 14 matches the end face of the side groove block 50. Or they are designed to have the same shape. In the longitudinal direction (the direction of the length L1) of the water collecting block 10, the width W7 of the side groove block 50 is matched with the width W7 in the range of the length L2 from the second side wall 12, that is, the side groove block 50 It is designed to have the same shape as the end face.

  Therefore, the drainage block 10a in the construction state in which the knockout hole 29 of the first side wall 11 is punched to form the water channel 28, and further, the knockout hole 29 of the third side wall 13 is punched to form the water channel 28. The second side wall 12, the side wall 57 of the side groove block 50 of the side groove 2b, and the side wall 57 of the side groove block 50 of the side groove 2c are flush with each other, that is, the outer surface of those side walls. Can be connected so that is almost straight. For this reason, when constructing the gutter system 1 along the boundary 105, it is possible to suppress the generation of a gap between the boundary 105 and the gutter block 50.

  FIG. 16 is a cross-sectional view of the state in which the water collecting block 10a and the side grooves 2a to 2c are connected, cut along a plane parallel to the bottom surface. The wall thickness t2 of the second side wall 12 of the water collecting block 10a is substantially the same as the wall thickness of the side wall 57 of the side groove block 50, and the water channel 28 connected to the meeting place 26 of the water collecting block 10a. The width W9 is substantially the same as the width W9 of the water channel 56 of the side groove block 50. Therefore, the water channels 56 of the side grooves 2c and 2b connected to the first side wall 11 and the third side wall 13 of the drainage basin block 10, respectively, have irregularities on the inner surface of the side groove through the waterhole 26. Connected with almost no connection.

  The wall thickness t1 of the first side wall 11 of the water collecting block 10a and the wall thickness t3 of the third side wall 13 are substantially the same as the wall thickness of the side wall 57 of the side groove block 50. The width W9 of the water channel 24 connected to the meeting place 26 of the water tank block 10a is substantially the same as the width W9 of the water channel 56 of the side groove block 50. Accordingly, the water channel 56 of the side groove 2a connected to the fourth side wall 14 of the water collecting basin block 10 is also connected to the water collecting basin 26 with almost no irregularities on the inner surface of the side groove.

  In the catchment block 10a, as shown in FIG. 16, a water channel 24 is provided in advance, and the wall thickness t4 of the fourth side wall 14 that does not need to be punched out at the construction site is increased to ensure strength. Yes. As can be seen from a comparison with the example shown in FIG. 24, the cross-sectional area of the portion where the cross-sectional area is the smallest can be ensured when constructing the T-shaped gutter system.

  That is, in the example shown in FIG. 24, the cross-sectional area of the portion that becomes the boundary between the side grooves when the side grooves are joined so as to intersect at 90 degrees becomes extremely small. On the other hand, in the water collecting block 10 (10a), the fourth side wall 14 is thickened and the water channel 24 is formed in advance, so that when the side grooves are connected so as to intersect at 90 degrees, the fourth side wall 14 is formed. The side wall 14 serves as a boundary between the side grooves, and the cross-sectional area is increased. Typically, the cross section of the portion (corner, corner, corner, leg portion) that becomes a boundary when the side grooves are joined so as to intersect at 90 degrees is wide by making it rectangular instead of square. A cross-sectional area is secured. For this reason, the wall thickness t2 of the second side wall 12 facing the fourth side wall 14 can be the same as the wall thickness of the side wall 57 of the side groove block 50, and the side groove block 50 and the land boundary 105 It is possible to prevent the gap G from occurring between the two.

  Further, the upper side of the fourth side wall 14 is a slab portion 21 made of concrete, and the fourth side wall 14 becomes a thick gate-shaped structure as a whole. For this reason, even if the knockout hole 29 on the other side wall is punched out by the fourth side wall 14, the strength as the water collecting water block 10a can be secured. Therefore, the first to third side walls 11 to 13 can be made thin, and a water collecting block for punching out the wall at a knockout type site can be provided.

  Furthermore, in this catchment block 10 (10a), it mounts so that the three sides 31-33 of the lid | cover receiving frame 30 may be exposed on the 1st-3rd side walls 11-13. For this reason, the problem that the thickness of the concrete covering the lid receiving frame 30 cannot be secured can be avoided. Furthermore, by exposing the lid receiving frame 30, the three sides 31 to 33 of the lid receiving frame 30 can be placed on the first to third side walls 11 to 13, and the fourth side wall 14 is thick. The other side 34 of the lid receiving frame 30 can be mounted on the inner upper part of the side wall 14. Therefore, the lid receiving frame 30 can be supported by the side wall itself, and a structure that protrudes inward or outward from the side wall to support the lid receiving frame 30 can be eliminated. For this reason, it is possible to secure a wide opening from the top to the water collecting chamber 26, that is, an opening 39 for installing the lid 40. The drainage basin 26 is a portion where dirt, mud and the like are easily collected, and the drainage trap block 10 is also used for collecting and removing dirt, mud and the like. Therefore, since the opening 39 can be secured widely, the water collecting basin block 10 that is easy to maintain can be provided.

  Further, since the lid receiving frame 30 can be mounted immediately above each of the side walls 11 to 14 and does not need to project outward, the outer side surfaces 11a to 13a of the first to third side walls 11 to 13 are substantially in the vertical direction. Can be designed to spread flat. The water collecting block 10 (10a) is also suitable for the combination with the outer straight type side gutter block 50 in this respect, and the gutter system 1 in which a gap with the land boundary 105 is hardly generated can be constructed.

  Further, in the first to third side walls 11 to 13, the upper ends 38 of the three sides 31 to 33 of the lid receiving frame 30 are connected to the drainage block 10 (10a). (Upper surface) 58a. In the 4th side wall 14, the upper end (upper surface) 21a of the slab part 21 comes to be matched with the upper end (upper surface) 58a of the other gutter block 50 connected to the said water collecting basin block 10 (10a). ing. Therefore, the upper surface (upper end) of the first to fourth side walls 11 to 14 and the upper surface 58a of the side groove block 50 can be connected without a step (with few steps).

  The upper surface 21a of the slab portion 21 of the fourth side wall 14 is provided with a pattern 22 that is continuous with the upper surface 58a of the underdrain portion 58 of the side groove block 50 connected to the water collecting basin block 10 (10a). Can do. In this example, a grid pattern (lattice pattern) is given as the common patterns 22 and 54. The patterns 22 and 54 are not limited to this example.

  In the gutter system 1, the slab portion 21 of the fourth side wall 14 of the drainage basin block 10 has a common pattern with the side gutter block 50 to be connected, and the first to third side walls 11 to 13 At the connection portion with the side groove block 50, the edge 38 of the lid receiving frame 30 is only slightly visible. Therefore, the side groove system 1 which is visually gathered can be constructed by the side groove block 50 and the water collecting water block 10 (10a).

  In the drainage trap block of this example, all of the first to third side walls 11 to 13 can be punched so that an arch-shaped water channel is formed, but the first to third side walls At least one of the side walls 11 to 13 may be stampable so that an arch-shaped water channel is formed. The shape of the water channel 24 formed in the fourth side wall 14 and the shape of the water channel formed by punching the knockout holes 29 in the first to third side walls 11 to 13 are bowed or chamfered at the top. The shape is not limited to the arch shape, and may be a gate shape or a shape close thereto. Furthermore, instead of providing the knockout hole 29 in the first to third side walls 11 to 13, the water collecting basin block may be formed with an arch-type or gate-type water channel in advance.
