DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterway structure for constructing an artificial waterway for road gutters, civil engineering and agricultural purposes.

[0002]

2. Description of the Related Art Generally, a waterway structure is described by taking, for example, a gutter of a road as an example. A concrete waterway body which is buried in the ground with an opening directed upward to flow water, and a waterway body And a concrete lid for closing the opening. In recent years, in order to prevent noise during driving of automobiles, a technique of forming a roadbed in a porous manner has become widespread. In this case, since water such as rainwater reaches the gutter through the roadbed, a waterway main body is formed. The wall adjacent to the roadbed is made porous so that water can penetrate, and water flows down from the porous portion into the recess.

[0003]

By the way, in such a conventional water channel structure, foreign matters such as fine particles of earth and sand and dust adhere or stay on the porous portion of the water channel main body due to long-time use. Clogging occurs and the drainage function may be reduced.
The present invention has been made in view of the above-described problems, and makes it difficult for the water channel main body to be clogged with foreign matters such as fine particles and dust of the earth and sand adhered or retained therein, thereby reducing the drainage function. It is an object of the present invention to provide a water channel structure in which suppression is achieved.

[0004]

The technical means of the present invention for solving such a problem includes a recess having an opening, which is buried in the ground with the opening facing upward, and is provided with water. In a channel structure comprising a water channel main body through which water flows, and a lid placed on the open end of the opening of the water channel main body and closing the opening, acts on the lid at the open end of the opening of the water channel main body. The structure is provided with a water-permeable block that is elastically deformed by a load. As a result, water such as rainwater flows down through the permeable block into the recess of the waterway main body. In this case, even if foreign matter such as fine particles of earth and sand or dust adheres or stays on the water-permeable block, the load is not applied when, for example, a vehicle wheel passes or a pedestrian is placed on the lid. When actuated, the water-permeable block is pressed through the lid, and when there is no load, it returns to its original state by elasticity, so that the water-permeable block is expanded and contracted. Therefore, the foreign substance to be clogged is easily moved and caused to flow down due to the expansion and contraction, so that the clogging is suppressed. In other words, the load acting on the lid causes the water-permeable block to be washed, as it were, so that foreign substances are less likely to stay, so that clogging is suppressed. This prevents a situation where the water permeability is reduced and the drainage function is deteriorated.

[0005] If necessary, the water-permeable block is formed of an elastic resin material. Also, if necessary,
The water permeable block is formed by mixing an aggregate and an elastic resinous binding material that binds the aggregate. In this case, it is effective that the aggregate is formed of an elastic resin material. Further, if necessary, one of the lid and the water-permeable block is provided with an engagement projection, and the other of the lid and the water-permeable block is provided with an engagement recess to be engaged with the engagement projection. I have. Thereby, since the engaging concave portion and the engaging convex portion are engaged with each other, it is possible to prevent the lid from easily coming off, and to reliably expand and contract the water-permeable block by the load acting on the lid. Furthermore, as necessary, the water-permeable block is configured to be detachably attached to the opening end of the opening of the waterway main body. Thus, when the water-permeable block is replaced with a new one, it can be easily attached and detached, and the replacement operation can be easily performed.
