Dried-up river ecological management system capable of converting rain flood into available water

Abstract

The invention provides a dry river ecological management system for converting rain flood into available water, and relates to the field of ecological management, the dry river ecological management system comprises a plurality of groove storage riverbed units arranged above a water-bearing layer, and the groove storage riverbed units are distributed in a step shape along the extension direction of a river slope so as to allow the plurality of groove storage riverbed units to store water step by step; the groove storage riverbed unit comprises a foundation pit, and first anti-seepage structure layers are arranged at the bottom and the peripheral side walls of the foundation pit; water supplementing seepage layers are arranged in the underground areas between the adjacent groove storage riverbed units and between the groove storage riverbed units and the aquifer, the water supplementing seepage layers are communicated with the side wall of the foundation pit through water supplementing pipelines, and a second anti-seepage structure layer is arranged between the bottom of each water supplementing seepage layer and the aquifer. Rain and flood resources in the flood season are reserved and stored through the groove storage riverbed unit, and a riverway ecological water quantity support is built; meanwhile, through water storage, water storage and seepage water replenishing of the dry river, the river can basically keep a constant flow state, and the ecological environment of the river is restored.

Description

technical field [0001] The invention relates to the technical field of ecological management, in particular to an ecological management system for dry rivers that converts rain and flood into usable water. Background technique [0002] While my country's rapid economic growth and urbanization have made remarkable achievements, due to people's excessive development and utilization of environmental resources, the ecological problems of small and medium-sized rivers in my country have become more and more prominent, and the phenomenon of river cut-off and dryness has become increasingly serious. Especially for many seasonal rivers, the dry season has become the norm. As the country attaches great importance to the ecological environment, the comprehensive management of dry rivers has become an indispensable part, including solving the problems of water resource storage and lack of base flow. At present, water diversion from reservoirs and other sources is mostly used to replen...

AI Technical Summary

Problems solved by technology

At present, most of the water sources such as reservoirs are diverted to replenish water and maintain river ecology, but this method is costly and requires a large amount of engineering
