Drainage structure of municipal road and construction method of drainage structure

Abstract

The invention discloses a drainage structure of a municipal road and a construction method of the drainage structure. The drainage structure comprises a drainage well which is arranged between a motor way and a non-motorized vehicle lane, wherein a grating component is arranged at the well mouth of the drainage well; the grating component is of a cylindrical structure and the latticed component (the grating component) is transversely arranged at the well mouth of the drainage well; the grating component is arranged in a mode of being partially higher than the well mouth of the drainage well; the sides, close to the motor way and the non-motor way, of the edge of the well mouth of the drainage well are provided with concave accommodating grooves, and the sides, facing the well mouth, of the accommodating grooves are connected to the well mouth; the parts, connected to the well mouth, of the accommodating grooves are provided with filter screen frames; the filter screen frames are in clearance fit with the surface of the grating component; the grating component comprises a central shaft and blades which are connected between the outer circle of the grating component and the central shaft; the central shaft is rotatably connected to the inner wall of the drainage well; and two ends, in an axial direction of the grating component, of the blades are provided with hollowed-out parts. The drainage structure provided by the invention has the characteristics of being not easy to block and stable in drainage effect.

Description

technical field [0001] The invention relates to the technical field of municipal drainage, in particular to a municipal road drainage structure and a construction method thereof. Background technique [0002] In the drainage structure of municipal roads in the prior art, drainage wells connected to the municipal drainage system are usually arranged on both sides of the road, and drainage grids are installed at the openings of the drainage wells. In rainy days, the accumulated water on the municipal road and the non-motorized vehicle lanes on both sides will flow to the drainage grille and be discharged into the municipal drainage system. [0003] However, when the precipitation is large, the surface runoff will easily carry the surface garbage to the drainage grille, and the surface garbage will block the drainage grille, and the reduced drainage of the drainage grid will easily cause water accumulation on the road. Contents of the invention [0004] In view of the defici...
