Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pedestrian boundary side groove block, and more particularly, to a culvert type pedestrian boundary side groove block installed at a boundary between a roadway and a sidewalk.
[0002]
[Prior art]
In order to make the width of the sidewalk as large as possible so that pedestrians and baby carriages can pass safely and comfortably, a U-shaped gutter block with a pedestrian boundary block part formed at the upper end of the side wall located on the road side Many have been developed that effectively use the upper surface of the lid block installed at the boundary of the walking road and at the opening located on the sidewalk side of the U-shaped side gutter as the sidewalk surface.
[0003]
However, in the conventional U-shaped side groove as described above, a notch recess for drainage is formed on the side end surface of the lid block installed in the opening of the U-shaped side groove. When installed in the opening of the letter-shaped side groove, the notch recess opens at the connection between the lid block on the upper surface of the side groove. As a result, there is a danger that a toe of a pedestrian, a tip of a walking stick, a wheel of a stroller or the like is caught in the opening of the notch recess, and there is a problem in terms of safety of the pedestrian or the like.
[0004]
As a means for solving such problems, a culvert type drainage groove block as disclosed in Japanese Patent Application Laid-Open No. 2000-34769 is used, and is erected on the roadway side on the top surface of the top wall. To the same level as the upper end surface of the curb forming portion, or not disclosed in the present invention, by installing the pavement material outside the drain groove block and the same level as the upper surface of the top wall portion, A method of using the upper part of the drainage channel as a sidewalk surface is also conceivable.
[0005]
As a result, the upper part of the drainage ditch can also be used as part of the sidewalk surface, and when the width of the sidewalk surface is increased by that amount, the sidewalk surface has no notch recesses that can interfere with pedestrians, etc. Safety is ensured. In addition, the side wall located on the road side has an opening of the water passage that communicates with the drainage channel in the drainage channel, so that there is an advantage that rainwater on the roadside is quickly drained into the side channel. .
[0006]
[Problems to be solved by the invention]
However, in the invention of the Japanese Patent Application Laid-Open No. 2000-34769, when the drainage groove blocks are installed in parallel, the space formed between the curbstone forming portions of both drainage groove blocks is filled with planting soil, The space between the curbstone forming portions is a planting portion such as a flower bed, and it is not assumed that the planting portion is used as a sidewalk surface.
[0007]
Therefore, no consideration is given to the drainage on the side of the planting part. For example, when the planting part is diverted to be used as a sidewalk surface, the drainage on the sidewalk surface is a curbstone forming part. However, most of the rainwater will remain on the sidewalk surface, causing obstacles during walking.
[0008]
[Means for Solving the Problems]
The present invention has been made to solve the conventional problems as described above. The culvert-type side groove block and the pedestrian boundary block portion are integrated, and the top surface or the upper portion of the top wall portion is formed on the sidewalk. In addition to being able to be used effectively as a part or sidewalk surface, it is widely used as a sideway block for pedestrian boundary of various installation styles by further draining from the sidewalk side and the roadway side respectively. It aims to provide what can be done.

[0018]
Therefore, corresponding to the construction site, the side groove blocks A to E for pedestrian boundary shown in the embodiment are appropriately combined, and the pedestrian boundary block 2 is located on the side of the road R so that the pedestrian boundary block 2 is positioned on the side of the road. Install. At this time, a vehicle entry portion is formed by installing a side groove block that is not provided with the pedestrian road boundary block portion 2 (not shown) between the pedestrian road boundary side groove blocks B to E.
[0019]
Next, the sidewalk W side of the side groove blocks A to E for the pedestrian road boundary installed at the boundary part of the pedestrian road is paved with a pavement material, and on the other hand, the side of the roadway R side is paved with a water-permeable pavement material. The sidewalk W and the roadway R are paved as follows. That is, on the sidewalk W side, a pavement material was laid on the outside of the top wall portion 1c such as a side groove block A for the pedestrian road boundary, and the pavement material was paved as shown in FIG. The upper surface of the paved sidewalk Wa is set to the same height as the upper surface of the top wall 1c. Thereby, the upper surface of the top wall portion 1c also becomes a part of the width of the sidewalk W, and can be effectively used as a sidewalk surface.
[0020]
On the other hand, on the roadway R side, a water-permeable pavement layer K is formed by laying a water-permeable pavement material on an impermeable roadbed G. When the water-permeable pavement layer K is formed on the water-impervious roadbed G, the end of the water-permeable pavement layer K on the side in contact with the side wall 1b on the road side is formed on the side wall 1b. It is formed at a position facing the drain hole 4. That is, as shown in FIG. 2 (b), the opening of the drainage hole 4 on the roadway side is entirely covered by the end face of the water-permeable pavement layer K formed on the water-impermeable roadbed G, or illustrated. However, only the lower part of the opening is covered so that the upper part of the opening of the drainage hole 4 is viewed from the upper surface of the water-permeable pavement layer K.
[0021]
By using the pedestrian boundary side groove block A or the like having the above-described configuration, the rainwater that has fallen on the top wall portion 1c has the top surface of the top wall portion 1c inclined slightly downward toward the pedestrian boundary boundary block portion 2. Therefore, it is guided by this inclined surface and drained into the drainage channel through the drainage hole 3 on the sidewalk side formed in the base of the walking road boundary block 2. On the roadway R side, rainwater on the permeable pavement layer K penetrates the permeable pavement layer K, passes through the drainage holes 4 on the roadway side, and is drained into the drainage channel. Here, the clogging of the drain hole 4 can be prevented by installing the filter 5 at the opening of the drain hole 4.
[0022]
As shown in FIG. 2 (b), the side groove blocks A to E for the pedestrian boundary according to each of the above-described embodiments are such that the upper surface of the paved sidewalk Wa and the upper surface of the permeable pavement layer K on the side of the roadway R are the same height. In addition, the flat type is configured to be lower than the upper end surface of the walking road boundary block portion 2 or the upper surface of the permeable pavement layer K is slightly lower than the upper surface of the paved sidewalk Wa, and from the upper end surface of the walking road boundary block portion 2. It is used for building a semi-flat pedestrian road with a low configuration.
[0023]
However, depending on the installation location, the top surface of the paved sidewalk Wa is flush with the top surface of the walking road boundary block 2 and the top surface of the walking road boundary block 2 from the top surface of the permeable pavement layer K on the road R side. In some cases, a so-called mount-up type pedestrian road is constructed in which the upper surface of the permeable pavement layer K is configured to have a predetermined height, that is, the level difference is required for the pedestrian boundary block. .
[0024]
FIGS. 7 and 8 show a pedestrian boundary side groove block according to a sixth embodiment of the present invention that is used when a pedestrian road having such conditions is constructed. The difference between the pedestrian road boundary side groove block F and the pedestrian road boundary side groove blocks A to E according to the embodiment lies in the structure of the drainage holes on the sidewalk, and the other configurations are the same. More specifically, when the concave groove 7 in the vertical direction is formed on the side wall surface 2c on the sidewalk side of the pedestrian road boundary block portion 2, the top wall portion 1c located at the lower end of the concave groove 7 is drained. A drainage hole 3 communicating with the road is formed.
[0025]
The pedestrian boundary side groove block F is installed at the boundary of the pedestrian path in the same manner as described above. And on the sidewalk W side, paving materials are laid on the upper surface of the top wall portion 1c of the side groove block F for the pedestrian road boundary and on the outside of the top wall portion 1c, respectively, as shown in FIG. an upper surface and a walking road upper end surface of the boundary block portion 2 of the paving sidewalk W _b paved by the paving material to build at the same height.
In the figure, K is a water-permeable pavement layer formed on a water-impermeable roadbed G.
[0026]
The use in constructing a walking road construction as the walking roadway boundary for gutter block mount up format F as described above, rainwater that falls on the pavement sidewalk W _b is the slope gradient of the pavement sidewalk W _b It flows down in the direction of the pedestrian road boundary block part 2 along. The rain water flowing in the direction of the walking road boundary block portion 2 enters the recessed groove 7 formed on the side wall surface 2c on the sidewalk side of the walking road boundary block portion 2, and the side of the footpath formed at the lower end of the recessed groove 7 is drained from the drain hole 3 in the drainage path of the groove, it is prevented from accumulating water on the upper surface of the paving sidewalk W _b.
[0027]
【The invention's effect】
Since the side groove block for the pedestrian road boundary according to the present invention is configured as described above, rainwater and the like can be quickly drained from two directions on the sidewalk side and the roadway side by drainage holes on the sidewalk side and the roadway side. A single gutter block having a sufficient drainage function and a function as a walkway boundary block can be obtained. Also, since the drainage hole on the sidewalk is formed at the base of the pedestrian boundary block part, it does not disturb pedestrians, and the sidewalk surface is made barrier-free, ensuring the safety of pedestrians etc. In addition, since the top or top of the top wall can be effectively used as a sidewalk surface, it can be used freely in various installation formats required by the installation location, and there are various effects such as expansion of the range of use. .
