DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete block with an anti-clogging material, and its purpose is to collect not only rainwater flowing on a road surface but also rainwater that has permeated into the road surface. An object of the present invention is to provide a drainage facility block that can prevent clogging of a headrace for collecting water, can maintain water collection and drainage for a long period of time, and has excellent workability.

2. Description of the Related Art In general roads, expressways, parks, and urban roads, drainage facilities are provided to prevent a phenomenon that water is stored on a road surface due to rainfall or the like. Examples of such drainage facilities include a U-shaped gutter as shown in FIG. 69, a culvert as shown in FIG. 70, and an open channel having a circular waterway as shown in FIG.

[0003] As a method of collecting water from these drainage facilities, in the case of a U-shaped gutter having an open upper part or a circular waterway having a water inlet at the upper part, water flowing on the road surface is taken in from the upper part as it is. We collect water by thing. In the case of a culvert, water collecting basins are provided at required intervals, and water flowing on the road surface is taken in from the water collecting basins to collect water.

[0004]

However, in the above-mentioned conventional drainage system, only the water flowing on the road surface can be collected, so that the water collection is poor. When constructed on a drainable pavement road with a permeable surface layer constructed on the surface of the base layer, there was a problem that if there was a large amount of rainfall, rainwater that could not penetrate into the road surface would accumulate on the road surface. In view of such a situation, the inventor of the present application has previously described in Japanese Patent Application No. Hei 6-131109 a gutter that can guide rainwater that has permeated the road surface from a water inlet provided on a side wall to an internal drainage channel. is suggesting. This technology was excellent in that it could collect and drain not only the water from the road surface but also the water that had permeated the road surface, but had the following problems. In other words, rainwater that has penetrated the road surface flows into the headrace with a small amount of sediment, but from the viewpoint of strength, the headrace is narrower than the drainage channel. However, there is a problem that water is collected and drainage performance is reduced. This problem can be almost solved by burying stones and crushed stones in the part facing the water inlet and making them play the role of a filter. It took a lot of time and labor to bury the parts, and the workability was extremely poor. In addition, it is difficult to bury stones and crushed stones accurately over long distances at the location of the water supply port in field construction.
In some cases, the stones and crushed stones are displaced from the position of the water inlet and soil and the like intrude from that position, and the water inlet is clogged, and the water collection and drainage properties are sometimes reduced. Furthermore, in the field construction, materials that can be used to prevent clogging are limited to limited items such as chestnut stone and crushed stone, and materials with higher clogging prevention function and water collecting property are used in a wide range of materials. It was difficult to choose from among them. Therefore, the industry can collect not only rainwater that flows on the road surface but also rainwater that has penetrated into the road surface, and can prevent clogging of the headrace channel that collects rainwater and collect it for a long period of time. Creation of a highly versatile block for drainage facilities that can maintain water and drainage properties, is excellent in workability, and can position and fix various types of clogging prevention materials with high precision is desired.
