Description

Technical Field

[0001] The utility model relates to the technical field of river section construction, and in particular to a water replenishment type ecological river channel construction structure. Background Art

[0002] How to optimize the ecological water replenishment method, improve the efficiency of water resource utilization, and take into account water landscape, water ecology, and water safety is of great significance to the ecological management of rivers.

[0003] In order to achieve ecological water replenishment and water purification in rivers, a variety of solutions have been proposed. For example, the invention patent with publication number CN116676910B discloses a method for ecological water replenishment using tidal power, including constructing a first water replenishment river channel in the middle and upper reaches of the main stream and tributaries of the river channel, storing water at high tide and replenishing the tributaries at low tide based on the first water replenishment river channel; setting up a regulating reservoir at the urban river channel, constructing a second water replenishment river channel at the other end of the regulating reservoir and the urban river channel, and replenishing the city based on the interconnected regulating reservoir, urban river channel, and second water replenishment river channel. For another example, the invention patent with publication number CN117700050A discloses a rainwater regulation and storage wetland purification system and purification method, which regulates and stores urban rainwater by setting a pre-pond, dry creek, wetland purification pond and river channel that are connected in sequence along the water flow direction, realizing the rational utilization and discharge of rainwater resources, reducing the risk of urban waterlogging, purifying rainwater, avoiding water pollution, and protecting the environment.
