Improved regulation and storage system for urban road rainwater collection and green land conservation

Abstract

The invention discloses an improved regulation and storage system for urban road rainwater collection and green land conservation. The improved regulation and storage system comprises a control system, a drainage ditch, a coarse filtration tank, a fine filtration tank, a regulation and storage tank and a back-flushing device, wherein the drainage ditch, the coarse filtration tank, the fine filtration tank, the regulation and storage tank and the back-flushing device are communicated in sequence, a frame-shaped filtration grille for filtering the rainwater collected by a rainwater perforated strainer is hung at the top end of a wall body of the drainage ditch, a filtration screen is arranged at the connecting position of the drainage ditch and the coarse filtration tank, a seepage well is communication with the regulation and storage tank through a drainage pipe, a filtration structure for filtering the rainwater is arranged at the top end of the seepage well, and the bottom of the seepage well is installed in a sponge water-storage layer. The regulation and storage tank comprises a side wall, a bottom wall and a plurality of watering water pipes, the back-flushing device comprises a water inlet pipe, a water pump, a back-flushing pipe and a blow-off pipe, and the bottom end of the coarse filtration tank and the bottom end of the fine filtration tank are communicated through a mud discharging pipe. The control system comprises a control unit, a magnetic valve and a plurality of humidity sensors. A liquid level sensor is installed on the upper surface of the section, where the regulation and storage tank is located, of an overflow pipe. The water pump, the humidity sensors and the liquid level sensor are all connected with the control unit.

Description

technical field [0001] The invention relates to the technical field of rainwater regulation and storage, in particular to an improved regulation and storage system for urban road rainwater collection and green space conservation. Background technique [0002] With the significant acceleration of the urbanization process in our country, the continuous expansion of the city scale, the intensification of the urban ground hardening, resulting in the increase of the rainwater runoff coefficient and the acceleration of the confluence, in case of heavy rain, the road surface is prone to water accumulation, and in severe cases, it is easy to cause urban road traffic paralysis and casualties. The non-point source pollution caused by rainwater erosion has increased the difficulty of urban sewage treatment, and at the same time brought a certain pressure on the urban pipeline network for flood discharge. However, after the heavy rain, it fell into the predicament of dryness and water ...

AI Technical Summary

Problems solved by technology

[0003] 1. In the event of heavy rain, the surface runoff of the city will be greatly increased, and the flood discharge capacity of the municipal pipe network is far from sufficient, causing road floods and waterlogging; 2. Rainwater soaking will carry a large amount of domestic garbage and pollutants on the ground, which will block the municipal pipe network. 3. A large amount of rainwater is discharged into the natural water body through the municipal pipe network, which will increase the load on the river system and even cause ecological environment damage; 4. Cause a large loss of rainwater resources , cannot be fully recycled
