Diversion ecological spur dike

Abstract

The invention relates to a diversion ecological spur dike which is a dike-shaped construction with one end connected with a river bank and the other end extending to a river channel, and the diversion ecology spur dike and the river bank form a T shape on a plane. The dike is characterized in that a plurality of layers of diversion plates are arranged at the periphery of the lower part of a dike body, the diversion plates are rigid plates, one side of each diversion plate is fixed on a spur dike body, and two vertical side edges of each diversion plate are connected with side edges of other diversion plates at two sides. Compared with the common spur dike, the diversion ecological spur dike disclosed by the invention has an ecological effect, high stability and the same regulation effect.The diversion plates are beneficial to the attachment and the survival of various water-based creatures, low turbulent fluctuation zones among the diversion plates are beneficial to the retention andthe attachment of the water-based creatures, strong turbulent fluctuation zones provide spaces for fishes to play with water, so that the needs of various biological natures can be met, and the ecological effect is remarkable. The maximum scouring depth and the scouring pit range of a dike head of the dike can be reduced to certain extent, a scouring pit has the tendency of moving facing downstream, and being far away from the direction of the dike head, so that the diversion ecological spur dike is beneficial to the stability of the dike body.

Description

technical field [0001] The invention relates to a spur dike, in particular to a diversion ecological spur dike with a new structure. Background technique [0002] Groove dam, also known as T-shaped dam, is the most commonly used type of river channel regulation and channel regulation structure. It is a dam-shaped building with one end connected to the river bank and the other end extending to the river channel. It is connected to the river bank in a T-shape on the plane. In the river control project, the spur dike protects the river bank from erosion by deflecting and diverting the flow; in the channel improvement project, it satisfies the navigation depth by narrowing the river channel and converging water to attack sand. There are many types of spur dikes, which can be classified into linear, hook-shaped and T-shaped according to the plane shape. As far as the materials for constructing spur dikes are concerned, block stone spur dikes are most commonly used in renovation ...

AI Technical Summary

Problems solved by technology

The ecological investigation of the Xijiang River shows that the development of the waterway improvement project of the Xijiang River has reduced the quality of habitat conditions and even caused the loss of the original biological habitat, which will have an adverse impact on the survival of benthic animals; The spawn ground of the

Therefore, while spurting water to attack sand to meet the navigation depth, it also destroys and threatens the river ecosystem, and the formation of scour pits at the head of the dam brings new problems to the stability of the dam body
