Ecological landscape barrage and construction method thereof

Abstract

The invention discloses an ecological landscape barrage and a construction method thereof. The ecological landscape barrage comprises a barrage and various stages of hydraulic drops, wherein the barrage is a water-retaining building, the zigzag multi-stage tandem hydraulic drops are arranged at the downstream part of the barrage and next to the barrage, so that a multi-stage artificial waterfall with fall change is formed, hydraulic drop ponds are arranged between the barrage and the first-stage hydraulic drop, and between each two stages of the hydraulic drops separately, and used for energydissipation, and meanwhile, a fish way is arranged or a fish ladder is directly formed as a biological migration channel by virtue of the multi-stage tandem hydraulic drops; each stage of the hydraulic drop pond doubles as a landscape pool; and in addition, with regard to the barrage without overflow in dry seasons, ecological flow drainage holes are formed in the middle part of the barrage, and double as fish passing holes. According to the ecological landscape barrage and the construction method thereof, the problems of passing-over of fishes and other migratory organisms, and local cutoff of the downstream part of the barrage, are solved; protection for the biological diversity of a river is benefited; and the plane landscape effect, the elevation landscape effect and the overall landscape stratification of the barrage are improved, so that the barrage has the functions of being convenient for people and hydrophilic, and has good social and economic comprehensive benefits.

Description

technical field [0001] The invention relates to the technical field of barrage engineering, in particular to an ecological landscape barrage and a construction method thereof. Background technique [0002] Barrages and dams appeared earlier in the history of human water control. People built barrages and dams on rivers to meet the needs of production, irrigation and domestic water. Especially in modern times, with the improvement of productivity, a large number of barrages and dams have been built in our country, mainly distributed in river courses in hilly areas. [0003] As a low-head water-retaining structure, traditional barrages and dams are mainly used to back up high water levels to facilitate water intake or shipping, and their functions are relatively single. In recent years, with the development of society and economy, people's requirements for water landscape have been increasing day by day. Various landscape barrages and dams have been built purely for landscape...

Problems solved by technology

[0006] In order to solve the problems existing in existing barrages and dams and give more functions to the barrages and dams, the present invention provides an ecological landscape barrage and its construction method that is flat, beautiful in facade shape, and has the functions of ecological flow discharge and fish passing. , can be widely used in the fields of water conservancy, environment and landscape engineering
