Watercourse and rubber dam water storage system

Abstract

The invention belongs to the technical field of river water storage, and particularly relates to a watercourse and rubber dam water storage system. A plurality of rubber dam bodies are arranged along a watercourse from upstream to downstream; one end of each rubber dam body is directly connected with one bank of a watercourse dike; the other end of each rubber dam body is connected with the other bank of the watercourse dike by a biological hanging film; and every two adjacent rubber dam bodies are directly connected with embankments on the two sides of the watercourse dike respectively, that is every two adjacent biological hanging films are positioned on different embankment sides of the watercourse dike respectively. Rubber dams are distributed in a plane in a staggered manner, and a water flow is urged to go forward in a bending manner, so that the retention time of a water body is prolonged, a flow rate of the water flow is increased, and an overall water quantity discharge rate is reduced; when water inflow quantity is increased, the water flow can be discharged automatically, and a water storage effect is not affected; multiple low water head rubber dam groups are used jointly, so that a water storage area and the length of the watercourse with the water are increased effectively; and when the water flow flows across the biological hanging films, water quality purification treatment is performed, so that a purpose of improving the water quality is achieved.

Description

technical field [0001] The invention belongs to the technical field of river water storage, in particular to a river rubber dam water storage system, which is especially suitable for water storage and water quality improvement projects of urban rivers in northern arid regions. Background technique [0002] The ecological environment of rivers in the north is generally poor. A considerable part of the rivers is in a state of water shortage or dryness all year round, and there is a lack of ecological water. However, during the flood period, these rivers are often responsible for flood control and drainage. Therefore, how to rationally use these rivers, rationally store water, and ensure ecological water and landscape water without affecting their flood drainage functions has become a research hotspot. Therefore, while constructing water storage projects in rivers in northern cities, it is also necessary to take into account flood control and water quality issues. [0003] Wit...

AI Technical Summary

Problems solved by technology

This kind of situation is suitable for nodal water storage in dry rivers, but due to the static water body and the front of the dam, the self-purification ability is weakened, and eutrophication is prone to occur

When the height of the dam crest is lower than the water level in front of the dam, the water body is discharged through overflow. Although the discharged water body has a certain aeration function when passing through the dam head, most of the bottom layer in front of the dam is a dead water area, which is not conducive to improving water quality.
