Abstract

PROBLEM TO BE SOLVED: To drain percolating water quickly, and to prevent water retained on a road surface by forming drain holes to receiving frames for a drainage basin for a road, laid with a draining paving material, and for a ditch cover used for a side ditch. SOLUTION: Drain holes 8 are bored to the vertical sections or corner sections among vertical sections and horizontal sections of a receiving frame 6 laid on a water gathering basin and the top face of a side ditch 2 formed of water-impermeable concrete. A draining paving material 5 is laid up to the same height as the top face of the receiving frame 6. Consequently, rainwater permeates into the draining paving material 5, and quickly flows into a drainage basin and the side ditch 2 from the drain holes 8. Accordingly, since the draining paving material 5 can be laid up to sections near to the drainage basin and the side ditch 2 and percolating water is drained rapidly through the drain holes 8, water retained on a road surface can be prevented.

いる。2. Description of the Related Art Conventional road pavement is usually formed of a material such as asphalt or cement concrete having high density. For this reason, road surface water generated by rainfall and snow melting is collected and drained by a drainage basin through a drainage means at the shoulder of the road using cross slope, etc., but it is inevitable that some amount of road surface water remains. In addition, it is inevitable that the road surface water stays in a rut or a locally defective portion of the vehicle. The accumulated road surface water causes not only a hydroplaning phenomenon, a slip, a splash, a smoking phenomenon, and the like, but these phenomena themselves often cause a vehicle driving error and cause a traffic accident. It is said that.

にしたものが存在する。In recent years, a drainage pavement has been proposed and put into practical use in which the surface layer of a road is formed of a material having a high porosity and rainwater or the like is directly immersed in the surface layer so that road surface water is not generated. A surface layer is formed by laying a drainable pavement material at a predetermined thickness on a base layer of a road, and a spiral-shaped infiltration water drainage channel is buried along the longitudinal edge of the drainage surface layer portion. In addition, there is a configuration in which the permeated water drainage channel is connected to a drainage device so that the permeated water permeated from the surface of the permeated water drainage is drained quickly and reliably.

使用している。Conventional drainage basins and gutters are generally formed by casting concrete in a formwork. To connect the seepage drainage channel to the drainage basin, an opening is provided on the side as shown in FIG. It is provided and drained through the seepage water drainage channel (11).
Normally, drainage basins and gutters are made of impervious concrete.

る。[0005] Since the receiving frame of the groove lid used in such a place is considered to be used only in close contact with the impermeable concrete, a steel angle member or plate is bent into an L shape or a Z shape. It is common to just attach an anchor.
