Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower engineering, in particular to a gate chamber bottom plate steel lining structure. Background Art

[0002] In water conservancy and hydropower projects, the lock chamber is an important hydraulic structure for regulating water flow and velocity, and its overall safety is of vital importance, especially for water transfer structures with relatively high water flow velocities such as diversion tunnels and diversion tunnels, where higher safety requirements are placed on the lock chamber.

[0003] Under the scouring effect of high-speed water flow, especially high-speed water flow carrying sediment and other bed loads, it will cause scouring damage to the concrete of the bottom plate of the gate chamber, resulting in the lifting of the bottom plate steel bars and difficulty in opening and closing the gate. For this reason, the industry has tried to arrange steel linings on the bottom plate of the gate chamber to protect the concrete, which has achieved certain results. However, the steel lining structure currently used generally has problems such as difficulty in fixing, inconvenient concrete pouring and vibration, and loose grouting. Utility Model Content
