In water conservancy and hydropower engineering, a high-water-head sluicing tunnel usually adopts a shaft type lock chamber, and the arrangement of the lock chamber needs to mainly consider the operation requirement of a gate, the water flow condition in the lock chamber and the maintenance and overhaul conditions of a metal structure. For a working gate with high operation requirement, a radial gate is generally adopted in engineering, and has no gate slot, smooth flow channel and better water flow condition. The flow state in the flat gate slot is relatively disordered, cavitation is easy to generate under high flow velocity, and the local opening limitation is strict, so that the flat gate slot is generally used for accident maintenance of a high-head water drainage tunnel. In view of the water flow condition defect of the flat gate, the arc-shaped working gate is generally adopted in the engineering for the sluicehole without the requirement of partial opening. When a shaft type lock chamber is adopted, in order to meet the arrangement requirements of a radial working gate hinge and a hoist, the bottom of the shaft needs to be expanded and dug towards the downstream side; in part of projects, the condition of maintenance and overhaul of equipment is taken into consideration simultaneously, and only an accident overhaul gate is arranged in a vertical shaft gate chamber, and then an arc-shaped working gate chamber is additionally arranged. A few sluices without local opening requirements adopt flat plate working gates and are intensively arranged in a vertical shaft together with an accident overhaul gate, but the rear part of the working gate is directly connected with a non-pressure flow passage.
For a drainage tunnel without a local opening requirement, the length of the bottom of a lock chamber needs to be increased when an arc-shaped working gate is arranged in a vertical shaft, and the daily maintenance and overhaul conditions of the gate and a hydraulic hoist are extremely poor; the working gate chamber arranged outside the vertical shaft needs to increase more investment and is more dispersed in maintenance and overhaul. And the plate accident overhaul gate and the working gate are arranged in the vertical shaft in a centralized way, so that although the investment is saved and the maintenance and the overhaul are convenient, the defects of gate chamber section water flow disorder, high cavitation erosion risk and the like exist when the non-pressure flow channel is directly connected behind the working gate.
