Sponge city roadbed drainage device

Abstract

The invention discloses a sponge city roadbed drainage device. The device comprises a roadbed, a drainage channel and a water storage box. The middle of the top end of the roadbed is provided with thedrainage channel, a water leakage cover plate is hinged to one side of the top of the drainage channel through hinges, hooks are fixedly arranged at the four corners of the bottom end of the water leakage cover plate, and the bottoms of the four hooks are in clamped connection with the four corners of the top end of a filter screen respectively. T-shaped sliding grooves are formed in the middlesof the inner walls of the two sides of the drainage channel, the bottoms of one sides of the two T-shaped sliding plates are fixedly connected with the middles of the two sides of the water storage box respectively, and a permeable membrane is fixedly arranged in the middle of the inner wall of the water storage box. According to the sponge city roadbed drainage device, a water body flowing into the drainage channel is preliminarily filtered through the filter screen, and then the water body is filtered for the second time through the permeable membrane, so that the water body flowing into thedrainage channel can be effectively filtered, and the practicability of the sponge city drainage device can be effectively improved.

Description

technical field [0001] The invention relates to a roadbed drainage device, in particular to a sponge city roadbed drainage device. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge and has good elasticity in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development rainwater system construction", which absorbs, stores, infiltrates, purifies water when it rains, releases the stored water and utilizes it when needed, and realizes the free migration of rainwater in the city. Starting from ecosystem services, constructing water ecological infrastructure across scales and combining multiple types of specific technologies to build water ecological infrastructure is the core of the sponge city. [0003] Existing sponge city subgrade drainage devices can ...
