Description

  The present invention relates to a water permeable groove member used to construct a drainage groove that allows rainwater to penetrate into the surrounding ground.

  In recent years, most of the surface of urban areas is paved with impermeable concrete and asphalt, as well as roadways and sidewalks, as well as sites and parking lots around buildings. Therefore, during heavy rains, a large amount of rainwater flows into the sewer through the drainage channel. Has risen and flooded, and flooding has occurred in the surrounding area.

  As a means of coping with such a situation, by giving water permeability to the groove member that constitutes the drainage channel and allowing some of the rainwater flowing through the drainage channel to penetrate into the ground, There has been proposed a water permeable groove member that reduces the amount of rainwater that flows in. Such a conventional water permeable groove member is formed by forming a drain hole in the bottom wall or side wall of a concrete U-shaped groove block and filling the drain hole with a water permeable member made of porous concrete or the like. (For example, see Patent Documents 1 and 2).

In addition, as another water permeable groove member, a large number of water permeable holes are drilled in the side wall portion of the concrete U-shaped groove block so that the earth does not flow from the water permeable holes when backfilling with earth and sand during construction. In addition, a configuration is also known in which a water-permeable material such as single-grain crushed stone having a diameter larger than the water-permeable holes is disposed on the outside (see Patent Document 3).

The split groove member pair configured to be divided into left and right at an intermediate position in the width direction of the bottom wall portion is joined so as not to be separated in a state in which the split portion end faces of the divided bottom wall portion are abutted with each other, and the opening width A material in which the left and right side wall portions are joined to each other via a plurality of connecting rods defining Thus, by making a groove member main body into a metal thin plate, it becomes very lightweight compared with the thing made from the conventional concrete, and will become the thing excellent in the handleability.

  In addition, each of the divided groove members constituting the pair of divided groove members can be formed by bending a metal thin plate using a die and a punch, so that the depth dimension of the bottom wall portion and between the left and right side wall portions are The upper opening width dimension can be freely set, and the user's desired dimension can be easily accommodated.

  Further, the spacer is formed integrally with the blocking wall member, or is formed separately or attached to the rear surface of the blocking wall member or the side wall portion of the groove member main body, so that the blocking wall member and the groove member main body are attached. It can interpose between the outer surface of the side wall part of this.

  In the water permeable groove member, the blocking wall member and the spacer are integrally formed by partially denting the flat blocking surface portion of the blocking wall member and projecting the spacer to the back surface side. Is proposed.

  Here, a hard synthetic resin or a metal thin plate can be applied to the material of the blocking wall member. Then, in the case of a hard synthetic resin, a flat blocking surface portion and a spacer protruding to the back side can be integrally formed by injection molding, or in the case of a metal thin plate, by press molding.

  In addition, a configuration is proposed in which the blocking wall member includes a water-permeable sheet that covers the water-permeable holes of the groove member main body so that the water-permeable holes of the groove member main body can pass through the opposing surface of the blocking surface.

  Here, a porous thin leaf sheet such as a fiber sheet is suitably used as the water permeable sheet, and the water permeable sheet can be held by the front end portion of each spacer on the opposing surface of the blocking surface portion.

  The groove member main body is fixed to the outer surface of the side wall portion, and the insertion end gap extends from the mounting end edge and corresponds to the thickness of the barrier wall member and the spacer with respect to the side wall portion.

Is discharged outside through the drainage gap, and the discharged rainwater is immersed in the ground. It can be. And since the groove member body is made of a thin metal plate, it is lighter than concrete and can be easily handled and transported and constructed, and the size and shape can be easily changed. Therefore, it can easily correspond to the user's desired dimensions. Further, by providing a blocking surface portion positioned at an appropriate interval via a spacer on the outer surface side of the side wall portion of the groove member body, water permeability of the side wall portion of the groove member body is obtained when backfilling with earth and sand during construction. The earth and sand do not flow from the hole. Thereby, since a water-permeable material such as single-grain crushed stone is not required as in the conventional configuration, the construction cost does not increase and the construction does not take time.

  Further, in the water permeable groove member, the blocking wall member and the spacer are integrally formed by partially denting the flat blocking surface portion of the blocking wall member and projecting the spacer to the back surface side. In the configuration, the structure is simplified by integrating the blocking wall member and the spacer, the number of members can be reduced, and it can be manufactured easily and inexpensively.

Below, one Example of the water-permeable groove member 1 concerning this invention is described based on FIGS.
As shown in FIGS. 1 and 2, the groove member main body 2 constituting the water permeable groove member 1 is made of a thin metal plate having a substantially U-shaped cross section. A plurality of water permeable holes 4 are formed at predetermined intervals. Each water-permeable hole 4 is formed as a vertically long slot extending from the middle height position closer to the lower side of the left and right side wall parts 3, 3 to the bottom wall part 5. In the height range of the long hole, the amount of drainage can be smoothly increased or decreased in accordance with the level of rainwater flowing inside. In addition, it is also possible to form each water-permeable hole 4 circularly or squarely, and to line up and down.

  The groove member body 2 is made of a stainless steel or steel thin plate having a thickness of about 1.5 to 6.0 mm, the opening width dimension W (see FIG. 3) is about 10 to 100 mm, and the depth dimension H is about 100 mm. It is formed with about 200-500mm. Further, the overall length is formed with a standard size of 1000 mm, such as 1000 mm, 2000 mm, and the like.

  Here, as shown in FIGS. 1 and 3, the groove member main body 2 includes a bottom wall portion 5 extending in the longitudinal direction and left and right side wall portions rising upward from left and right side edges of the bottom wall portion 5. 3 and 3, and a split groove member pair 6 (see FIG. 3B) that is divided into left and right at an intermediate position in the width direction of the bottom wall portion 5 is shown in FIG. As described above, the divided end face surfaces 7 and 7 of the divided bottom wall portion 5′5 ′ are joined to each other so as not to be separated by welding, and the left and right side wall portions 3 and 3, and the side wall portions Both ends of the plurality of connecting rods 8 defining the opening widths 3 and 3 are joined by welding.

  FIG. 4 shows a thin metal plate 10 as a material of each divided groove member 9 constituting the divided groove member pair 6 (see FIG. 3B), and one side of a virtual fold line 11 bent by a brake press. Are provided with a bottom wall piece portion 12 serving as a bottom wall portion 5 ′, and a side wall piece portion 13 serving as a side wall portion 3 on the other side of the virtual folding line 11. That is, the horizontal width of the thin metal plate 10 is cut into a predetermined dimension that combines the horizontal width dimension of the bottom wall portion 5 ′ and the height dimension of the side wall portion 3 of the divided groove member 9 to be formed. Further, a plurality of fitting insertion holes 14 into which the end portions of the connecting rods 8 (see FIG. 3A) and the plurality of water permeable holes 4 described above are punched or formed at predetermined positions of the thin metal plate 10. Each is formed by laser processing.

  Then, as shown in FIG. 5A, the metal thin plate 10 is placed on a die 15 set in a brake press (not shown), and a virtual folding line 11 is formed on the die 15 at a right angle V. The thin metal plate 10 is bent by a punch 17 that is positioned on the shaped groove 16 and has a bent end having a shape matching the V-shaped groove 16. Thereby, as shown in FIG. 5 (B), the metal thin plate 10 is bent at a right angle along the virtual fold line 11, and the divided groove is bent so that the bottom wall portion 5 'and the side wall portion 3 form a right angle. The road member 9 is formed.

  Using a pair of divided groove members 9 formed in this way, as shown in FIG. 3 (A), opposingly arranged in a state where the divided portion end faces 7 and 7 of the bottom wall portion 5′5 ′ are abutted, While connecting the end surfaces 7 and 7 of the divided portions so as not to be separated from each other by welding, the connecting rods 8 are inserted into the fitting insertion holes 14 and 14 of the left and right side wall portions 3 and 3, respectively. 8 and the edge of the insertion holes 14 and 14 in contact with the two end portions are joined together by welding so that the upper opening width dimension W between the left and right side wall portions 3 and 3 is changed from the upper end to the bottom wall portion. A groove member main body 2 made of a thin metal plate having a substantially U-shaped cross section that is smaller than the depth dimension H up to 5 can be obtained.

  When the upper openings of the left and right side wall portions 3 and 3 are shielded by the groove lid 18 (see FIG. 2), a plurality of connecting rods 8 that connect the left and right side wall portions 3 and 3 are connected to the groove lid 18. In this case, the connecting rod 8 is disposed at a height where the upper surface of the groove lid 18 and the upper end surfaces of the left and right side wall portions 3 and 3 are substantially flush with each other. The

  Thus, by making the groove member main body 2 made of a metal thin plate, it becomes extremely lighter than a conventional concrete product and is excellent in handleability. Further, each divided groove member 9 constituting the divided groove member pair 6 can be formed by bending the thin metal plate 10 using the die 15 and the punch 17, so that the depth dimension H of the bottom wall portion 5 and The upper opening width dimension W between the left and right side wall parts 3 and 3 can be freely set, and can easily correspond to the user's desired dimension.

  As shown in FIGS. 1 and 2, blocking wall members 19, 19 are disposed on the outer surface sides of the left and right side wall portions 3, 3 of the groove member main body 2. Each blocking wall member 19 includes a flat blocking surface portion 20 that covers the water permeable holes 4 of the side wall portions 3, and inflow of earth and sand from the water permeable holes 4 formed in the left and right side wall portions 3, 3 by the blocking surface portions 20. Can be cut off. Each blocking wall member 19 is positioned at an appropriate interval on the outer surface side of the side wall portion 3 by a spacer 21 interposed between the blocking surface portion 20 and the outer surface of the side wall portion 3 of the groove member body 2. In addition, the spacer 21 generates a drainage gap 22 continuous at least in the vertical direction between the blocking surface portion 20 and the outer surface of the side wall portion 3.

  The blocking wall member 19 and the spacer 21 are integrally formed by partially denting a flat blocking surface portion 20 and projecting a plurality of spacers 21 on the back surface side. Here, the spacer 21 may be formed in a required shape such as a frustoconical shape, a U-shaped cross section, or a semicircular cross section. The barrier wall member 19 and the spacer 21 are made of a hard synthetic resin such as polyethylene or a metal thin plate such as stainless steel or steel. Therefore, the flat blocking surface portion 20 and the plurality of spacers 21 protruding to the back surface can be integrally formed by injection molding in the case of a hard synthetic resin or by press molding in the case of a thin metal plate. Thus, by integrating the blocking wall member 19 and the spacer 21, the structure becomes simple, the number of members can be reduced, and the assembly work is not required, so that it can be manufactured easily and inexpensively. The spacer 21 is not integrally formed with the blocking wall member 19 as described above, but is attached separately to the back surface of the blocking wall member 19 or to the outer surface of the side wall portion 3 of the groove member body 2. Further, it can be interposed between the blocking surface portion 20 and the outer surface of the side wall portion 3 of the groove member main body 2.

  The blocking wall member 19 includes a water permeable sheet 23 that covers the water permeable holes 4 of the groove member main body 2 on the opposite surface of the blocking surface portion 20 so as to allow water to pass therethrough. The water permeable sheet 23 is composed of a porous thin leaf sheet such as a fiber sheet formed to be approximately the same size as the blocking surface portion 20, and is integrated with the distal end portion of each spacer 21 through welding or adhesion. The water-permeable sheet 23 is not necessarily required and can be removed. In this way, by providing the water-permeable sheet 23 that covers the water-permeable holes 4 on the opposing surface of the blocking surface portion 20, When backfilling with earth and sand, the inflow of earth and sand from the water permeable holes 4 can be more reliably prevented.

  In addition, holder members 24 and 24 for holding upper portions of the left and right blocking wall members 19 and 19 are disposed on the side wall portions 3 and 3 of the groove member main body 2, respectively. Each holder member 24 is formed in a cross-sectional crank shape having a mounting edge 25 at the upper portion and a holding edge 26 at the lower portion by bending the strip-shaped metal thin plate. Is fixed to the outer surface of the side wall 3 so that the lower holding edge 26 extended from the upper mounting edge 25 is fitted to the side wall 3 corresponding to the thickness width of the blocking wall member 19 and the spacer 21. The upper part of the blocking wall member 19 can be held by the holding edge 26 by being suspended with the insertion gap 27 interposed therebetween.

  Further, a plurality of support members 28 that support the lower ends of the blocking wall members 19 and 19 are disposed below the side wall portions 3 and 3 of the groove member main body 2. Each support member 28 is made of a band-like metal plate, and is fixed to the lower surface of the bottom wall portion 5 of the groove member main body 2 at a predetermined interval in a state of protruding from the side wall portions 3 and 3 to the left and right sides. Then, by mounting the blocking wall members 19 and 19 on the support member 28 and supporting the lower ends thereof, the blocking wall members 19 and 19 can be held at a predetermined height position. In combination with the holding action of the upper portions of the barrier wall members 19 and 19 by 24 and 24, the barrier wall members 19 and 19 can be prevented from falling off during transportation and construction. As shown in FIGS. 1 and 2, the support member 28 functions as an anchor by protruding from the side wall portions 3 and 3 to the left and right sides by a predetermined length.

  FIG. 6 shows a construction state of the water permeable groove member 1 having such a configuration. Here, the construction of the water permeable groove member 1 is that the water permeable groove member 1 is arranged in series in the groove dug in the ground, and then the earth and sand are buried around the water permeable groove member 1. Is done. When the earth and sand are backfilled, the blocking wall members 19 and 19 are disposed on the outer surface side of the side wall portions 3 and 3 of the groove member main body 2, so that the blocking surface portions 20 and 20 of the blocking wall members 19 and 19 are disposed. Thus, the backfilled earth and sand can be blocked, and the earth and sand are prevented from flowing into the groove member main body 2 from the water permeable holes 4 of the side wall portions 3 and 3. Further, the blocking surface portions 20 and 20 and the side wall portions 3 and 3 are provided by a spacer 21 interposed between the blocking surface portions 20 and 20 of the blocking wall members 19 and 19 and the outer surface of the side wall portions 3 and 3 of the groove member main body 2. The drainage gaps 22 and 22 that are continuous in the vertical direction are provided between the outer surface and the outer surface of the drainage, and after the construction, the drainage grooves 1 are arranged to flow in the drainage groove. A part of the rainwater is discharged to the outside through the drainage gaps 22 and 22 from the water permeable holes 4 of the side wall portions 3 and 3 of the groove member main body 2, and the discharged rainwater penetrates into the ground.

  As described above, according to the present invention, part of the rainwater flowing in the drainage channel is discharged to the outside through the drainage gaps 22 and 22 from the water permeable holes 4 of the side wall portions 3 and 3 of the channel member body 2. The drained rainwater can penetrate into the ground. And since the groove member main body 2 is made of a thin metal plate, it is lighter than conventional concrete, can be obtained with excellent handling properties during transportation and construction, and can be changed in size and shape. Since it is easy, it can respond easily to a user's desired dimension. Further, by providing the blocking surface portions 20 and 20 positioned at appropriate intervals via the spacers 21 on the outer surface side of the side wall portions 3 and 3 of the groove member body 2, the groove member can be refilled with earth and sand during construction. The earth and sand do not flow from the water-permeable holes 4 in the side wall portions 3 and 3 of the road member body 2. Thereby, since a water-permeable material such as single-grain crushed stone is not required as in the conventional configuration, the construction cost does not increase and the construction does not take time.
