River channel multi-level intelligent ecological revetment system based on sponge city

Abstract

The invention discloses a river channel multi-level intelligent ecological revetment system based on a sponge city. The system comprises a river channel, an ecological slope protection and a river bank, wherein a step type stone cage is arranged between the ecological slope protection and the river bank; trees and shrubs are planted on the river bank, the ecological slope protection comprises a clay layer, a denitrification layer, an adsorption layer, a filtering layer and a soil layer, wherein herbaceous plants are planted on the soil layer, and a water distribution pipeline is arranged at the top end of the ecological slope protection; an inductor control cabinet is arranged at the upper end of the step type stone cage, a water level sensor is arranged at the front end of the step type stone cage, the water level sensor is provided with a DO monitoring probe, and an aeration pump and a sewage pump are arranged in the river channel; and the water level sensor, the DO monitoring probe,the aeration pump and the sewage pump are connected to the inductor control cabinet, and the sewage pump and the water distribution pipeline are connected through a water collecting pipeline. According to the system, the effects of "water absorption, water storage, water seepage and water purification" during rainfall are fully realized, the problem that the purification effect in rainfall or river flood season of an ordinary ecological revetment is limited is solved, and the problem of poor water quality of the river channel in dry season is solved.

Description

technical field [0001] The invention relates to the field of river management, and more specifically relates to a sponge city-based multi-level intelligent ecological revetment system for rivers. Background technique [0002] In recent years, the ecological environment of river courses has been severely damaged, and eutrophication and soil erosion have occurred frequently. Bank revetment is an important transition zone for material exchange, energy flow, and information transmission between water ecosystems and terrestrial ecosystems. It is of great practical significance to enter river and lake water bodies, prevent large-scale erosion of water and soil, stabilize river banks and beautify the environment. [0003] The existing revetment technologies for river regulation mainly include the following categories: natural revetment, hard revetment, ecological revetment, etc. Among them, the natural bank revetment is a revetment that plants plants on the river revetment, uses p...

AI Technical Summary

Problems solved by technology

However, there are also some deficiencies in ecological bank revetments, which do not fully realize the effect of sponge city "fully accumulating during rainfall and releasing the stored water for use when needed"; these technologies have limited purification effects on pollutants during rainfall or river flood seasons , cannot purify rainwater and river water at the same time; the degree of firmness is not as good as traditional hard revetment; the popularization and use are limited
