Water gate energy dissipation structure

Abstract

The invention discloses a water gate energy dissipation structure which comprises gate bottom plate. The lower portion of the gate bottom plate is provided with a concrete cushion. A drop wall is connected to the lateral side of the gate bottom plate. The drop wall is of an integral structure poured and formed by concrete at one step. More than one draining pipes are arranged in the drop wall. The distance between every two draining pipes is 2-3cm. A cyclone section is disposed at the bottom of the drop wall and communicated with the drop wall. A falling limb is disposed at the bottom of the cyclone section and parallel and communicated with the cyclone section. A Reno mattress armor layer is parallelly disposed on the lateral side of the drop wall. The water gate energy dissipation structure has the advantages that the structure is applicable to riverway deformation with large upstream and downstream fall cause by sand excavation and the like, easy to maintain, low in noise and sufficient in energy dissipation effect, the requirement of upstream and downstream water connection can be satisfied, and energy dissipation is achieved by using the mutual effects such as buffering, impact and fluctuation of water flows.

Description

technical field [0001] The invention relates to an energy dissipation structure, in particular to a sluice energy dissipation structure. Background technique [0002] The existence of large-scale dangerous sluices affects the operation of sluices, and even endangers the flood control safety of water conservancy structures such as embankments, which restricts the sustainable development of the national economy to a certain extent. Therefore, promoting the reinforcement of large and medium-sized dangerous sluices as a It is an important task to strengthen the construction of weak links in farmland water conservancy, and it is an urgent problem to be solved. In some provinces and cities, the phenomenon of sand mining is widespread in most rivers and has been repeatedly prohibited. Excessive excessive mining and dredging of river sand will seriously affect the shape of the river bed, the flow of water, and even lead to severe downcutting of local river sections or the entire riv...

Problems solved by technology

In some provinces and cities, the phenomenon of sand mining is widespread in most rivers and has been repeatedly prohibited. Excessive excessive mining and dredging of river sand will seriously affect the shape of the river bed, the flow of water, and even lead to severe downcutting of local river sections or the entire river bed, changing and deteriorating. Therefore, it is necessary to take corresponding countermeasures for this series of problems, so as to better avoid the problem that the river bed is not easy to be damaged.
