Description

Technical Field

It is a component of the road boundary surface drainage facilities and an indispensable part of the road drainage system. As municipal construction becomes more rigorous and beautiful, people's requirements for side ditches are also increasing. Drainage side ditches are mainly set up on both sides of the road surface, and then set up grates on the drainage ditch to drain water. However, in the actual drainage process, a large amount of debris will enter the side ditch through the gaps in the grate, which can easily cause blockage of the side ditch.

[0003] In the prior art, application number 202020466222.3 discloses a permeable drainage ditch for municipal roads, comprising a ditch body, the ditch body being detachably connected with a rainwater grate, the ditch body being movably connected with a permeable device, the permeable device comprising a permeable plate and a fixed frame, the permeable plate and the fixed frame being slidably connected, the fixed frame and the ditch body being cooperatively arranged, the permeable plate comprising a permeable concrete layer, a pressure mesh layer and a permeable pressure plate, the ends of the permeable pressure plates close to each other are fixedly connected to the pressure mesh layer, and the pressure mesh layer and the permeable concrete layer are fixedly connected; the above structure can only perform permeable treatment on rainwater entering the ditch, and rainwater on the road surface needs time to flow before it can be collected and drained through the grate, which greatly reduces the drainage effect of the road surface, and the flat grate and the ditch structure are simple, and the ditch receiving the flow of rainwater for a long time will reduce the stability of the concrete inner wall of the ditch.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
