Drainage ditch for alleviating drainage pressure

Abstract

The invention relates to the field of drainage ditches and aims to provide a drainage ditch for alleviating drainage pressure. According to the technical scheme, the drainage ditch is characterized bycomprising a ditch bottom and ditch walls, wherein the ditch walls are respectively arranged on both sides of the ditch bottom; overflowing holes are formed in the ditch walls; overflowing holes aresealed and covered with baffle blocks; hollow chutes are formed in the ditch walls in axis directions of baffle blocks; screw rods are horizontally arranged inside the chutes; the screw rods are rotationally connected to the chutes and transversely penetrate through the baffle blocks; guide parts for guiding the baffle blocks to slide in length directions of the screw rods are arranged inside thechutes; first bevel gears are rotationally connected to the inner surfaces of the ditch walls in length directions of the ditch walls; transmission parts for driving the screw rods to rotate are arranged between the first bevel gears and the ditch walls; and torsional springs are arranged between the first bevel gears and the ditch walls. The drainage ditch is applicable to construction of road water drainage facilities.

Description

technical field [0001] The present invention relates to the field of drainage ditches, and more particularly, it relates to a drainage ditch capable of relieving drainage pressure. Background technique [0002] Drainage ditch refers to the ditch that guides the water collected in the side ditch, intercepting ditch, and low-lying places near the roadbed, in the crop field, and near the residence to the ditch outside the roadbed, crop field, and residential area. It is a kind of road drainage facility. [0003] The drainage ditch is generally arranged at both ends or the lower end of the intercepting ditch on the slope to remove the surface runoff that the intercepting ditch cannot accommodate, and its terminal is connected to a reservoir or a natural drainage channel. [0004] In recent years, affected by global climate change, extreme weather such as heavy rain frequently occurs. In areas where infrastructure construction such as drainage and waterlogging is lagging behind, ...

AI Technical Summary

Problems solved by technology

[0004] In recent years, affected by global climate change, extreme weather such as heavy rain frequently occurs. In areas where infrastructure construction such as drainage and waterlogging is lagging behind, and stormwater storage and emergency management capabilities are insufficient, the precipitation has increased sharply due to heavy rain. The pressure is high, and it is easy to have the problem of water accumulation on the road, and even cause serious rainstorm and waterlogging disasters, which will affect social management, urban operation and people's production and life
