  The present invention relates to the creation of a concrete part for road surface drainage, which can appropriately drain water from the road surface during rainfall and the like, and has an excellent workability, an L-shaped gutter block for road surface drainage and other concrete parts and road surface. It is intended to obtain a drainage device. In the present invention, the rigid body forming the water permeable section is a rigid body made of a resin such as metal, plastic, or the like, or ceramic.

  If a puddle occurs on the road surface during rainfall, etc., it will cause slippage on the running vehicle and water splashing, and irregular reflections such as lights will hinder the safe driving of the vehicle. For smooth operation, porous drainage pavement with a porous surface of a certain thickness has come to be used, and rainwater that has penetrated into this pavement can be quickly drained and installed on the roadside. In order to collect water in the ditch, some contrivance has been conventionally made.

  That is, FIGS. 1 and 2 show such a construction example. In the U-shaped groove block 8 and the gate-shaped groove block 8a, a water collecting hole 47 is provided, and a porous drainage material 50 is provided around the water collecting hole. A filled water collecting portion 48 is formed, and a waterproof sheet 49 is laid outside the water collecting portion 48. Rain water from the drainage pavement portion 21 formed on the road surface is drained into the side grooves 8 and 8a via the water collecting portion 48. It is designed to fall.

  In Japanese Utility Model Laid-Open Publication No. Sho 61-173585, several trapezoidal grooves are formed from the upper end of one of the outer surfaces of the side wall of the gutter, and a communication hole which is inclined at the inner surface of the side wall is provided at the bottom, and a filter is provided in the trapezoidal groove. It has been proposed to insert and guide rainwater into the gutter.

Further, JP-A-5-148814 discloses that a water-permeable road surface plate is laminated on a base concrete having a water-guiding groove on the surface, and rainwater is transmitted through the road surface plate to reach the surface of the base concrete, and water is drawn. It has been reported that water is collected and drained to the gutter side via a groove. These are all gutters, and are not supported by pedestrian road boundary blocks or L-shaped gutter blocks.
