Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter block installed on a shoulder of a road on which drainage pavement is provided, and a road surface structure.

[0002]

2. Description of the Related Art When a large amount of rain falls on a general asphalt-paved road, rainwater flows on a pavement surface and is guided to a gutter installed on a road shoulder. It is jumped up and this bothers pedestrians on the sidewalk. Therefore, in order to prevent hydroplaning due to rainwater on the road surface, on the other hand, a low-noise drainage pavement for reducing a ground contact sound between the road surface and a vehicle tire has been used.

As shown in FIG. 6, in a conventional drain groove pavement block (a), the height of the top plate (c) of the road surface (b) is the same as that of the gutter block (a). For this reason, it is well known that the side wall vertical surface (d) of the side groove block (a) is provided with an inflow hole (e). Therefore, since the upper surface (f) of the concrete top plate of the gutter block (a) appears at the shoulder of the road, the rain falling on the shoulder flows down the upper surface of the concrete (f) of the gutter block (a). For the purpose, it is impossible to prevent the water running up by the vehicle traveling on the road side end.

[0004] Regarding the "drainage groove for water-permeable pavement" disclosed in JP-A-7-16620 and the "block for gutter" disclosed in JP-A-8-109673, drainage pavement is provided on the upper part of the gutter block. All have a water collecting structure made of metal or the like which is installed at the end of the drainage pavement, that is, material cost and mounting cost are different from concrete alone.

In the drainage pavement, an impermeable layer for flowing down the inside of the drainage pavement is provided below the drainage pavement having a drainage function. In all directions, the drainage pavement is provided to a position where the distance from the road surface in the road plan is constant. By setting the upper surface of the gutter block so as to coincide with the upper portion of the water-impermeable layer, the thickness of the drainage pavement on the upper surface of the gutter block and the road portion becomes the same. However, when the gutter block is installed in this way, the vertical slope of the road surface and the installation slope of the gutter must be equal.

Here, in a gutter block such as a culvert type in which the bottom of the gutter is integrally formed, the slope of the road surface is equal to the slope of the bottom of the gutter. If the user wants to drain the drained water in the direction, a problem occurs.

[0007]

Thus, by installing the upper surface of the gutter block whose bottom is integrally molded so as to coincide with the upper part of the water-impermeable layer, the thickness of the drainage pavement on the upper surface of the gutter block and the road portion is improved. There is a problem as described above in the same road structure. The problem to be solved by the present invention is this problem, and even with such a road surface structure, it is easy to flow into the gutter block through the drainage pavement, and the gutter is formed without being affected by the slope of the road surface. A flowable gutter block and road surface structure are provided.

[0008]

The gutter block of the present invention is constructed as a gate-shaped block having an open bottom surface so that concrete can be poured into the bottom so that a predetermined running water gradient is obtained after installation at the site. . Also, an opening is provided between the upper beams to facilitate the work of placing the concrete on the bottom and leveling the iron on the top surface of the cast concrete, and the cover plate is placed after the casting of the concrete on the bottom. Of course, these basic structures are well known for the side groove block.

In order to enhance the water collecting function of the drainage pavement side gutter block, a notch serving as an inflow hole is also provided at the end of the cover plate. In order to increase the water collecting function, a step is provided on one side of the beam part of the gutter block, and an inflow hole is formed at the end of the step to prevent the drainage pavement part on the upper surface from falling when the inflow hole is enlarged. In order to prevent sand and dust from entering the wastewater flowing from the drainage pavement, a thin plate-shaped mezzanine with water holes may be installed.

Further, in the structure in which the drainage pavement is entirely covered with the upper part of the gutter block, the step forms a space between the drainage pavement and the drainage pavement, and the drainage flows through the space as a mini channel. Also, a plurality of grooves are formed to improve the adhesion between the drainage pavement and the upper surface of the side groove block. Rainwater that reaches the upper surface after passing through the drainage pavement can flow into the inside through the ditch. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0011]

FIG. 1 is an embodiment showing a gutter block for drainage pavement according to the present invention. The gutter block has a substantially gate-shaped cross section, has an upper beam 1 and both side walls 2 and 2, and a central portion of the upper beam 1 has a large opening 3. Reference numeral 4 in the figure denotes a cover plate, and both cover plates 4 and 4 are attached to close the opening 3 of the upper beam portion 1. A step 5 is formed on one side of the upper beam portion 1 so as to be lowered, and an inflow hole 6 is formed at an end of the step 5.
Is formed.

.. Are provided on the upper surface 7 of the upper beam portion 1 in the vertical and horizontal directions.
Also, a groove 8 is formed. The center of the end surface 9 of the cover plate 4 is notched in a concave portion 10, and also has a notch 11 in a corner portion. From these inflow holes 6 and notches 11, rainwater that permeates the drainage pavement and flows down into the gutter block. The rainwater that has reached the upper surface 2 is in the grooves 8, 8 ...
Through the notch 11 and the step 5, and can flow into the side groove block.

FIG. 2 shows the cover plate 4. The end surface 9 is provided with a concave portion 10 at the center and a cutout portion 11 at a corner.
The recess 10 functions as a handle for the cover plate 4, and the notch 11 serves to flow rainwater into the inside of the side groove block. The rainwater that has reached the upper beam portion 1 and the cover plate 4 flows on the upper surface 7, and a part of the rainwater falls on the step 5, passes through the inflow hole 6 from the step 5, and falls into the gutter block. Also, the rainwater flowing on the upper surface 7 can flow down into the side groove block from the inflow hole formed by the notch 11.

FIG. 3 shows another embodiment of the present invention. In this embodiment, the upper surface of the upper beam 1 and the upper surface 7 of the cover plate 4 attached to the opening 3 have no grooves. The grooves 8, 8,... Formed on the upper surface 7 mainly improve the adhesion to the drainage pavement, but may not be used. Then, the rainwater that has reached the upper surface 7 flows from the notch 11 formed in the end surface 9 of the lid plate 4 into the inside of the side groove block. Step 5 from top surface 7
The rainwater that has flowed down flows into the side groove block from the inflow hole 6 formed at the end of the step 5. Further, in the embodiment shown in the figure, a mesa 12 is attached to the inflow hole 6 so that dust, sand and the like do not flow.

FIG. 4 shows a case where the gutter block according to the present invention is installed on a road shoulder, and FIG. 5 shows a sectional view in that case. When installing the gutter block, use the basic crushed stone 1

Here, the groove bottom 15 creates water flowing in the side groove block regardless of the inclination of the road surface. That is, the gutter block is disposed on the foundation concrete layer 14, and the impermeable layer 16 is provided so as to be at the same height as the upper surface 7 of the upper beam 1. Asphalt is used for the water-impermeable layer 16, and a cover plate 4 is attached to the opening 3 to provide a drainage pavement 17. The thickness of the drainage pavement 17 is the same as that of the upper surface 7 of the upper beam portion of the gutter block on the road surface. In this way, the gutter block is installed parallel to the road surface,
The groove bottom 15 can be formed without being affected by the inclination of the road surface, and it is possible to arbitrarily drain water.

A boundary block 18 is disposed between the side edge of the road and the sidewalk, and the side groove block of the present invention is installed such that the step 5 is located on the boundary block 18 side. Therefore, even if the drainage pavement 17 is provided so as to cover the upper surface 7 of the gutter block and a space 19 is formed between the step 5 and the drainage pavement 17, the drainage pavement 17 does not collapse. Also, the rainwater that accumulates facing the boundary block 18 flows through the drainage pavement 17 and flows down into the space 19 formed by the step 5, and then flows down through the space 19 and falls into the inside of the gutter.

As described above, the gutter block according to the present invention has a substantially gate-shaped cross section, has a large opening in the upper beam, and has a step on the side of the upper beam and an edge at the end.

[0019]

The gutter block of the present invention has a gate-shaped cross section, and the upper beam has a large opening to which a cover plate is attached. Therefore, even in a road surface structure in which drainage pavement is provided on the upper surface of the upper beam portion of the gutter block, concrete can be poured from the large opening of the gutter block and the groove bottom slope can be leveled without being affected by the road surface. I can do it.

The side groove block is provided with a step at the side of the upper beam portion, an inflow hole is formed at the end, and a notch is provided at the end face of the cover plate, so that drainage is prevented. Rainwater flowing in the pavement flows down from these inflow holes into the gutter block. In addition, by attaching a mesa to the entrance of the inflow hole, dust and sand can be prevented from flowing down to the gutter block. On the other hand, by forming a narrow groove on the upper surface, the adhesiveness with the drainage pavement is improved, and at the same time, rainwater flows through the groove and flows down to a notch or a step.

Further, by installing the gutter block such that the step is located on the boundary block side, a space is formed between the gutter block and the drainage pavement provided so as to cover the upper surface of the gutter block, and the rainwater flowing down to the step is removed. It flows smoothly in the space and falls into the gutter. Since the space is on the boundary block side, the vehicle load traveling on the road does not directly act, and the drainage pavement does not collapse into the stepped space.
