Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a boundary water guide groove block laid mainly along a boundary between a roadway and a sidewalk.
[0002]
[Prior art]
In the paved road dividing the roadway and the sidewalk, a drainage facility is provided at the boundary between the roadway and the sidewalk in order to prevent rainwater from staying on the road surface. In the simplest drainage system, a curb block is continuously laid at the boundary between the roadway and the sidewalk, the road surface is inclined downward toward this curb block, and the corner between the curb block side surface and the sloping lower end of the road surface is inclined. There is a corner drainage ditch.
[0003]
In addition, an apron portion is extended from the lower end of the curb block portion to the roadway side, and an L-shaped side groove having a substantially L-shaped cross section with a drainage groove at a corner area between the upper surface of the apron portion inclined downward and the side surface of the curb block portion An inflow opening that continuously lays a circular channel block that forms a circular water channel inside and that has an inflow opening that is narrower than the width of the circular water channel on its upper surface, and opens on the road surface In addition, there are also those with elongated gratings and lids attached.
[0004]
In each drainage facility, drainage basins are installed at predetermined intervals, and rainwater from drainage grooves and circular waterways is collected in the drainage basin, and drainage treatment is performed from the drainage basin to the sewerage. ing.
[0005]
However, if the corner area between the side of the curb block and the sloping lower end of the road surface is a drainage ditch, the foundation concrete has to be placed on site, so it takes time for construction and the drainage capacity is also small. So, during heavy rains, the water cannot be completely processed.
[0006]
In addition, in the case of a drainage facility using a circular channel block, a relatively large drainage capacity can be expected, but since the vertical dimension of the circular channel block is large, it must be deeply excavated during construction and requires a lot of labor. And Furthermore, since the inflow opening is opened on the upper surface, foreign matters such as sand and dust are likely to flow in. In the case of a circular water channel block, a curb block molded separately must be laid later, which is troublesome twice and the curb block is easily detached.
[0007]
In view of this, Japanese Patent Application Laid-Open No. 2002-61105 (Patent Document 1) proposes an invention related to a “boundary water guide groove block” that solves these problems. The present invention integrally molds an upstanding horizontal curb portion and first and second apron portions extending in a substantially horizontal direction from the lower portion of the curb portion, and tilts the upper surfaces of both apron portions downward toward the curb portion side. This is a boundary waterway groove block with a substantially convex cross section with a corner area as a drainage groove. Inside the lower part of the curb part, a through-hole serving as an internal water channel is formed along the longitudinal direction of the curb part. A water conduit having one end opened at the lower end of the side surface and the other end communicated with the through hole is formed.
[0008]

[0009]
[Problems to be solved by the invention]
By the way, in the boundary water guide groove block disclosed in the above publication, the sub through-hole serving as the sub-inner water channel is formed in the longitudinal direction of the curb portion in the thickness of the apron portion separately from the through-hole serving as the inner water channel. A sub-water conduit is formed within the thickness of the apron, with one end opening on the side of the apron and the other end communicating with the sub-through hole, and water flowing on the road surface of the roadway. It is introduced from the water conduit that opens at the lower end of the curb side, drains into the inner water channel, and water that flows through the water-permeable asphalt on the non-permeable asphalt is introduced from the secondary water channel that opens on the side of the apron. It drains into the internal waterway.
[0010]
Therefore, in this boundary conduit channel block, two internal water channels, an inner water channel and a sub-inner water channel, are formed along the longitudinal direction of the curb portion, and each of the water channel and apron opened at the lower end of the curb portion side surface. Since the secondary water conduit opened on the side surface of the part is connected, there is a problem that the structure is complicated, the molding is troublesome, and the strength is not easily secured.
[0011]
Therefore, the present invention provides a boundary water guide groove block that eliminates the drawbacks of the blocks used in the various drainage facilities described above, has a simple structure, is easy to mold, and has a high drainage capacity while ensuring strength. For the purpose.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an embodiment of a boundary conduit groove block according to the present invention, and FIG. 2 is a side view of the boundary conduit groove block shown in FIG.
[0017]
The boundary water guide groove block 1 of the present embodiment is a concrete integrally formed block having a substantially convex cross section laid in a column along the boundary between the roadway and the sidewalk, and has a horizontally long curb portion 2 standing on the top. A through hole 4 serving as a drainage channel 3 is formed along the longitudinal direction of the curb portion 2 in the lower portion of the curb portion 2, and the pavement is paved on the lower side of the curb portion 2. There is a road surface reference portion 5, and a water flow port 6 a is opened on the side surface having the road surface reference portion 5 so as to communicate with the drainage channel 3.
[0018]
The curbstone 2 is located in the upper half of this boundary waterway groove block 1 and is a portion that is exposed to the ground when laid along the boundary between the roadway and the sidewalk to construct a road pavement. Presents.
[0019]
A lower portion of the curb portion 2 has a substantially rectangular parallelepiped shape, and a through hole 4 serving as a drainage channel 3 is formed in the inside of the curbstone portion 2 along the longitudinal direction of the curbstone portion 2. A flowing water channel 6 having a flowing water port 6a is formed on the side surface of the portion 2 on the side of the roadway so as to communicate therewith. Although the drainage channel 3 is formed by the through hole 4 having a circular cross section having a diameter of about 100 mm in this embodiment, the cross sectional shape and the cross sectional area can be appropriately set.
[0020]
The road surface reference portion 5 serves as a reference for the upper surface of the water-permeable pavement (drainage pavement) such as water-permeable asphalt when paving the roadway. It is formed along the longitudinal direction of the curb portion 2 as a step portion protruding substantially horizontally outward (on the roadway side) from the top to the bottom, and the upper surface of the step portion is the upper surface reference of the permeable pavement. In the present embodiment, the road surface reference portion 5 protrudes 10 mm outward in the substantially horizontal direction, and since the protrusion width is small, it is not always necessary to incline it, but several according to the road surface gradient (water gradient) of the roadway. It may be inclined about%. In addition, the road surface reference portion 5 is integrally formed of concrete as a step portion protruding outward in a substantially horizontal direction. However, if the reference is clear, it is not limited to the step portion. For example, a member serving as a mark Etc. may be embedded in the concrete and integrally molded, or may be described after the molding.
[0021]
The water flow channel 6 has a water flow port 6a opened on the side surface of the curb portion 2 on the side of the roadway. The water flow port 6a is continuously open over the road surface reference portion 5 and below. The rain water flowing on the road surface of the roadway and the rain water soaking into the permeable pavement and flowing on the non-permeable pavement can be introduced. The bottom surface of the water flow channel 6 is inclined downward from the water flow port 6a toward the drainage channel 3, and the vertical width thereof is gradually reduced.
[0022]
In the boundary water guide groove block 1 illustrated in FIG. 1, a plurality of vertically long rectangular water outlets 6 a are opened at a predetermined interval. However, the present invention is not limited to this, and as shown in FIG. A plurality of water flow channels 16 having a water flow port 16a may be opened, and as shown in FIG. 5, a water flow channel 26 having a longer and longer rectangular water flow port 26a may be opened.
[0023]
Further, as shown in FIG. 3, a filter member 7 in which a road surface drainage portion 7a and a pavement drainage portion 7b are integrally formed is attached to the water flow port 6a. Prevents intrusion. The vertical cross-sectional shape of the filter member 7 is formed in a step shape corresponding to the side surface shape on the roadway side of the boundary water guide groove block 1 of the present embodiment, and has a bent portion 7c at the center in the vertical direction. The upper part becomes the road surface drainage part 7a, and the lower part becomes the pavement drainage part 7b. In this filter member 7, the water passage hole 8b formed in the pavement drainage portion 7b is set smaller than the water passage hole 8a formed in the road surface drainage portion 7a. Since the in-pave drainage part 7b which is the lower half part of the filter member 7 is located below the road surface reference part 5 described above, it is buried under the road surface of the road (in the water-permeable pavement). Therefore, the water passage hole 8b of the drainage part 7b in the pavement is formed in such a size that an aggregate such as gravel used for the pavement cannot pass through. That is, in the present embodiment, the road surface drainage portion 7a is formed with a long hole-shaped water passage hole 8a along the vertical direction so as to prevent the entry of relatively large garbage such as dead leaves. Although the circular water passage hole 8b is formed in the part 7b so as to prevent the intrusion of the aggregate, the hole shape is not limited to these.
[0024]
In addition, although the filter member 7 integrally forms the road surface drainage part 7a and the pavement drainage part 7b, the road surface drainage part 7a and the pavement drainage part 7b are integrally formed of the same plate material. In addition to the above, a case where the road surface drainage portion 7a and the pavement drainage portion 7b are formed by separate members (for example, grating and punching plate) and are joined by welding or the like is also included.
[0025]
On the other hand, the lower side of the curb portion 2 on the sidewalk side has a walking road surface reference portion 9 that serves as a road surface reference for the sidewalk. The walking road surface reference portion 9 paved the sidewalk with asphalt or road surface blocks. In this embodiment, the curb portion 2 serves as a stepped portion projecting outward in a substantially horizontal direction (on the sidewalk side) on the side surface of the curb portion 2 on the side of the sidewalk. The upper surface of the step portion is the upper surface reference of the pavement surface. In the present embodiment, the walking road surface reference portion 9 protrudes 10 mm on the sidewalk side, and does not need to be inclined because the protruding width is small, but may be inclined about several percent along the road surface gradient of the sidewalk.
[0026]
Moreover, you may comprise so that it may have the base pavement reference | standard part 10 used as the upper surface reference | standard of water-impermeable pavement in the side part lower part which has said vehicle road surface reference | standard part 5. FIG. For example, when the intervals at which the water flow ports 6a of the water flow channel 6 are provided are relatively close or when the horizontally long water flow ports 16a and 26a are provided as shown in FIGS. 4 and 5, the lower ends of the water flow ports 6a, 16a and 26a. The part can be the base pavement reference part 10.
[0027]
Alternatively, as shown in FIG. 6, it is formed along the longitudinal direction of the curb portion 2 as a step portion projecting outward in a substantially horizontal direction (roadway side) on the side surface of the lower portion of the road surface reference portion 5. In other words, the upper surface of the base pavement reference portion 10 that protrudes becomes the upper surface reference of the non-permeable pavement surface. The base pavement reference portion 10 as the stepped portion is formed in the same manner as the vehicle road surface reference portion 5 and the walking road surface reference portion 9 described above.
[0028]
Next, the construction of the boundary conduit groove block 1 configured as described above will be described. In order to construct the boundary waterway groove block 1 of the present embodiment on the road, as shown in FIG. 7, the boundary portion between the roadway and the sidewalk is excavated and the foundation layer 11 is leveled, and the curb portion of the boundary waterway groove block 1 is formed. 2 is aligned with the boundary between the roadway and the sidewalk, with the side surface having the road surface reference portion 5 facing the roadway side and the side surface having the walking road surface reference portion 9 facing the sidewalk side, a predetermined interval (for example, an interval of 30 m ) And laying them in cascade one after another with a longitudinal gradient (water gradient in the longitudinal direction of the road) slightly inclined downward toward the water collecting basin arranged in (1).
[0029]
In addition, an annular seal member 12 is provided around the opening of the through-hole 4 that opens to the left and right end surfaces of each block 1 and the opening that opens to the side surface of the water catchment. When the water guide groove blocks 1 are sequentially laid, the through holes become a series of drainage channels 3 in a state where the connection portions are sealed in a watertight manner, and communicate with the water catchment.
[0030]
Then, a non-permeable pavement 13 such as a non-permeable asphalt is constructed with the base pavement reference portion 10 formed on the side surface on the roadway side of the block 1 as an upper surface reference, and further on the side surface on the roadway side. A water-permeable pavement 14 such as a water-permeable asphalt is constructed using the formed road surface reference portion 5 as an upper surface reference. At that time, the filter member 7 is attached in advance to the water flow port 6 a and is embedded in the water-permeable pavement 14. Accordingly, the pavement drainage portion 7b in the lower half portion of the filter member 7 is buried, and only the road surface drainage portion 7a in the upper half portion is exposed on the road. As described above, the boundary conduit groove block 1 of the present embodiment has the base pavement reference portion 9 and the road surface reference portion 5 on the lower side of the curbstone portion 2, so that the pavement material is constructed according to these reference portions 9 and 5. The height adjustment at the time of laying the boundary water guide groove block of the present embodiment is not necessary, and the height adjustment is not necessary at the time of constructing the pavement material.
[0031]
In the case of laying in this manner, excavation shallower than the excavation for laying a conventional circular water channel block may be used, so that construction work is easy. In addition, on the sidewalk side, when the sidewalk is one step higher than the roadway, that is, the mount-up method that is the same as the height of the upper end surface of the curb portion 2, the sidewalk with the same height as the roadway as shown in FIG. Even in the case of the flat construction method, the boundary waterway groove block 1 can be used in common, and is constructed in the same manner using asphalt, road surface blocks, etc. based on the above-mentioned walking road surface reference portion 9. The
[0032]
When it rains, rainwater flowing from the roadway directly flows into the water outlet 6a opened on the side surface of the curb portion 2, so that it is not necessary to flow rainwater in the longitudinal direction of the road. The rainwater flowing into the water flow port 6a flows down the flow channel 6 and enters the drainage channel 3, flows through the drainage channel 3 and is collected in a drainage basin, and is drained into the sewer. In addition, when rain water from the road surface flows into the water outlet 6a, dust such as dead leaves can be blocked by the road surface drain portion 7a of the filter member 7, so that large waste can be prevented from flowing into the drain channel 3. .
[0033]
Moreover, if a drainage channel is provided in the lower part of the curb portion 2 that functions as a conventional curb block, the excavation work area may be smaller than in the case where a drainage channel is separately provided, and the land is effectively used. If a separate drainage channel is provided, a space (land) for laying the drainage channel on the roadway side or sidewalk side must be secured. In this respect, the drainage channel is provided inside the boundary conduit channel block 1. This is because a space for the drainage channel is not necessary.
[0034]
When the amount of rainfall is low during rainfall, most of the rain that has fallen on the road surface penetrates into the water-permeable pavement 14 such as water-permeable asphalt and the upper surface of the water-permeable pavement 13 such as water-permeable asphalt. Flowing. And if it flows to the side surface of the boundary water guide groove block 1, it will be introduced into the drainage channel 3 through the flowing water channel 6 from the flowing water port 6a opened in this side surface, and will flow through this drainage channel 3 and become a water collecting trough. Collected and drained from here to sewers. As described above, in this embodiment, rainwater soaked in the permeable pavement 14 can be drained through the water flow channel 6 and the drainage channel 3. In addition, when rainwater soaked in the water-permeable pavement 14 flows into the water outlet 6a, the intrusion of the aggregate of the pavement material can be blocked by the in-pave drainage part 7b of the filter member 7, so Aggregate can be prevented from flowing in.
[0035]
That is, according to the boundary water guide groove block 1 of the present embodiment, the road surface reference portion 5 of the roadway is provided on the lower side of the curb portion 2, and the water flow port 6 a is opened on the side surface having the road surface reference portion 5. Since the flowing water channel 6 communicating with the drainage channel 3 is formed, and the water outlet 6a of the flowing water channel 6 is continuously open above and below the road surface reference portion 5, only rain water flowing on the road surface can be used. In addition, rainwater that permeates into the water-permeable pavement and flows on the non-permeable pavement can also flow into the same drainage channel 3, has a simple structure, is easy to mold, and has a high drainage capacity while ensuring strength. The provided boundary water guide groove block 1 can be provided.
[0036]
In addition, in the boundary waterway groove block 1 of this embodiment, the waterway is not opened on the sidewalk side, but the sidewalk side is provided with a waterway on the sidewalk side in the same way as the roadway side to open the water outlet. Rainwater flowing on the road surface or rainwater that permeates into the water-permeable pavement on the sidewalk side and flows on the non-permeable pavement can be introduced into the same drainage channel 3 to be drained. In this case, you may form a base pavement reference | standard part also on the sidewalk side.
[0037]
【The invention's effect】
As described above, the present invention has the following effects.
According to the first aspect of the present invention, there is a road surface reference portion of the roadway on the lower side of the curb portion, and the flow channel that opens the water outlet to the side surface having the road surface reference portion and communicates with the drainage channel. Formed and the water outlet of this waterway is continuously open above and below the road surface reference part, so that not only the rainwater flowing on the road surface, but also soaks into the water-permeable pavement. Rainwater flowing through can also flow into the same drainage channel. And it is possible to provide a boundary conduit groove block that is simple in structure and easy to mold, and has high drainage capacity while ensuring strength.
In addition, since it has a road surface reference part on the lower side of the curb part, it is possible to construct a pavement material according to this road surface reference part, and to adjust the height when laying the boundary conduit groove block of the present invention Therefore, height adjustment is not necessary when constructing pavement materials.
[0038]
Further , according to the present invention, a filter member that integrally forms a road surface drainage portion and a pavement drainage portion is attached to the water outlet, and the water passage hole formed in the pavement drainage portion rather than the road surface drainage portion. Is set small, and the water passage hole of the drainage section in the pavement has a size that prevents the aggregate of the pavement material from passing through. Therefore, it prevents intrusion of relatively large garbage such as dead leaves at the road surface drainage where rainwater flowing on the road surface flows, and pavement at the drainage area inside the pavement where rainwater flows into the water-permeable pavement and flows on the non-permeable pavement. Intrusion of the aggregate of the material can be prevented.
[0039]
According to the second aspect of the present invention, the lower part of the side surface having the road surface reference part has the base pavement reference part that becomes the upper reference of the non-permeable pavement, and therefore, the pavement material is constructed according to the base pavement reference part. It is possible only to adjust the height when laying the boundary conduit groove block of the present invention, and when adjusting a non-permeable pavement, it is not necessary to adjust the height.
[0040]
According to the invention of claim 3 , since there is a walking road surface reference portion that becomes the road surface reference of the sidewalk at the lower side of the curb portion on the side of the sidewalk, pavement material and road surface blocks are constructed according to this walking road surface reference portion. The height adjustment is not necessary when constructing a pavement or the like only by adjusting the height when laying the boundary conduit groove block of the present invention.
