DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter block for constructing a gutter provided on a road shoulder or the like for removing rainwater or the like.

[0002]

2. Description of the Related Art Conventionally, a side gutter is provided at a road shoulder or the like to remove rainwater or the like staying on a road surface. This side groove is generally constructed by connecting side groove blocks having a U-shaped cross section or a U-shaped cross section that are open at the top in the longitudinal direction. A groove cover such as a grating is provided at an upper opening of the side groove block, and the groove cover is laid so as to be substantially flush with a road surface.

[0003]

However, in the conventional gutter block, there is a problem that the earth and sand, dust and the like that have flowed in together with the rainwater stay in the bottom plate and are hardly discharged. In other words, if the amount of water flowing through the gutter is large, such as during heavy rain, the earth and sand, dust, and the like remaining in the bottom plate may be discharged along the flow of water. When the water content is small, the flow of water is not substantially generated, and the earth and sand, dust and the like remain in the bottom plate portion.
And these earth and sand, dust, and the like further hinder the flow of rainwater, and a vicious cycle of promoting stagnation of the soil, dust, and the like.

In addition, various conduits such as electric cables, gas pipes, and water pipes are laid underground, but are often laid separately from each other. In this case, the total laying cost is reduced. However, it is inefficient in terms of maintenance after installation.

[0005] Therefore, an object of the present invention is to provide a gutter block which makes it easy to discharge sediment, dirt, and the like that have accumulated in a bottom plate portion and makes the gutters versatile.

[0006]

In order to solve the above-mentioned problems, a gutter block according to the present invention has a U-shape whose upper portion is opened by a bottom plate portion and a side wall portion, and the upper surface of the bottom plate portion has a longitudinal direction. A groove is provided along the entire length of the groove.

[0007] By providing the grooves along the entire length of the bottom plate along the longitudinal direction, even if the amount of rainwater or the like flowing through the side grooves is small, the water flows preferentially through the grooves, so that the water flow is reduced. The sediment that is generated and stays on the bottom plate along this water flow,
Garbage and the like are easily discharged.

In the gutter block of the present invention, a lid plate is bridged between the groove provided on the bottom plate portion and the upper end of the side wall portion, and a space surrounded by the lid plate, the bottom plate portion and the side wall portion is provided. Pipes such as electric cables, gas pipes and water pipes can be laid.

With such a configuration, not only can the gutter be used for removing rainwater, but also it can be used as a space for laying conduits such as electric cables and water pipes, leading to effective use of the underground space. At the same time, it leads to a reduction in the cost of laying pipes. Further, the lid plate also has a function as a guide plate when a vehicle that has derailed in the gutter or when a small animal such as a cat or dog that has fallen into the gutter climbs up on the ground.

Further, when the cover plate is made detachable, when there is a possibility that rainwater overflows from the gutter during heavy rain, the rainwater can be removed and the rainwater flow path can be enlarged to perform emergency drainage.

[0011]

Embodiments of the present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 is a perspective view showing a first embodiment of a gutter block according to the present invention. As shown in FIG. 1, the gutter block A of the present invention is formed in a U-shape with an upper opening by a bottom plate portion 1 and side wall portions 2 and 3 rising from both ends thereof. Has a groove 1a formed over the entire length in the longitudinal direction. The material of the gutter block is generally concrete, but other materials such as synthetic resin may be used.

When a gutter is constructed by using the gutter block A, a plurality of gutters are connected in the longitudinal direction in the same direction and laid. (Not shown) and buried such that the upper surface of the groove cover is substantially flush with the road surface. Then,
The grooves 1a formed on the upper surface of the bottom plate portion 1 are continuously connected in the longitudinal direction. Even when the amount of water such as rainwater flowing in the side grooves is small, the water gathers in the grooves 1a to secure the water flow. In addition, the earth and sand, dust, and the like staying in the plate portion 1 along the water flow are easily discharged.

FIG. 2 is a perspective view showing a second embodiment of the gutter block of the present invention, and FIG. 3 is a sectional view taken along the line II of FIG.

The side groove block A shown in this embodiment is formed in a U-shape whose upper part is open for the bottom plate 1 and the side walls 2 and 3, and the groove 1a is formed in the bottom plate 1. This embodiment is the same as the previous embodiment. In this embodiment, however, in order to be able to lay a conduit such as an electric cable, a gas pipe, or a water pipe in the side groove, a gap between the groove 1a and the upper end of the side wall 2 is made. The cover plate 4 is hung.

The cover plate 4 is a rectangular concrete plate having the same length as the side groove block A, and one of its long sides is an engagement portion 4a fitted into the groove 1a. The other side of the side portion is a mounting portion 4b to be mounted on the upper end of the side wall portion 2.
It has been. As shown in FIG. 3, the engaging portion 4a has the same width and height as the groove 1a, so that the engagement portion 4a is securely fitted into the groove 1a. On the other hand, the mounting portion 4b is formed by bending so that the upper surface thereof is horizontal when the mounting portion 4b is mounted on the upper end of the side wall portion 2. The side wall portion 2 on which the mounting portion 4b is mounted is formed to be lower than the other side wall portion 3 by the thickness of the mounting portion 4b, and the cover plate 4 is formed between the groove 1a and the side wall portion 2. The upper surface of the mounting portion 4b and the upper end surface of the side wall portion 2 are made to have the same height when they are bridged between them. This is to allow the groove cover such as a grating cover to be installed horizontally when the upper opening of the side groove block A is covered.

The gutter block A of this embodiment has the above-described structure, and includes the cover plate 4, the bottom plate portion 1, and the side wall portion 2.
Thus, a space separated from the rainwater flow path is formed, and it is possible to lay pipes such as electric cables, gas pipes, and water pipes by using this space. When waterproofness is required in the space depending on the type of the pipeline to be laid, a sealing material may be used when the cover plate 4 is bridged.

Of course, the cover plate 4 is provided integrally in advance,
A space for laying a pipeline may be formed. However, as in this embodiment, if the cover plate 4 is separate from the gutter block main body and is detachable, when there is a possibility that rainwater overflows from the gutter during heavy rain, it is removed to remove rainwater. There is an advantage that the flow path can be expanded and emergency drainage can be performed.

[0019]

According to the gutter block of the present invention, even if the amount of rainwater or the like flowing through the gutter is small, the sediment, dust and the like staying in the bottom plate can be easily discharged.

Further, in the case where a cover plate is bridged between the groove provided on the bottom plate portion and the upper end of the side wall portion, an electric cable, a gas pipe,
Pipes such as water pipes can be laid, and the underground space can be effectively used, and the cost of laying pipes can be reduced.

Further, in the case where the cover plate is made detachable,
If there is a risk of rainwater overflowing from the gutter during heavy rain, the rainwater can be removed to enlarge the rainwater flow path and perform emergency drainage.
