A gate bottom sill seepage sealing device and its construction method

Abstract

The invention discloses a gate sill leakage blocking device and a construction method thereof. The blocking device comprises a gate panel, wherein fixed lifting pegs are arranged on the top surface of the gate panel, a blocking mechanism and a shield are arranged on the other side of the gate panel, and the blocking mechanism, which is connected with the gate panel through positioning fastening plates, comprises a blocking system and a hydraulic system; the blocking system comprises metal connecting parts, a holding plate and a rubber blocking board, the hydraulic system comprises a hydraulic line and hydraulic cylinders, the hydraulic cylinders are connected with each other through the hydraulic line, and the hydraulic line is connected with an external hydraulic power station. The blocking device is put down nearby a sill along with a gate, the hydraulic control system is switched on if the gate cannot drop to the bottom, the piston rods of the hydraulic cylinders extend out to push the rubber blocking board to the bottom water leakage place, and thereby blocking is complete. The gate sill leakage blocking device has a simple structure, and is highly practical, and the blocking effect of the gate sill leakage blocking device is enhanced, the severe water leakage of the gate is prevented , and the service life of the gate sill leakage blocking device is prolonged.

Description

technical field [0001] The invention relates to a leakage sealing device for a gate bottom sill and a construction method thereof. Background technique [0002] The sluice is one of the important buildings in the irrigation and drainage project. It is a low-head hydraulic structure that uses the gate to block or discharge water. It can control the flow and adjust the water level. When the gate is closed, it can hold back flood and store water, keep out the tide or raise the water level in front of the gate; when the gate is opened, it can discharge flood, drain waterlogged or supply water to downstream rivers or channels. [0003] During the construction of hydropower stations and reservoirs, temporary diversion facilities, such as diversion tunnels, diversion holes and other hydraulic structures, generally need to be blocked at the entrance of the diversion structure and cut off the water flow after completing the corresponding diversion mission, so as to facilitate constru...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a technical scheme of a gate bottom sill leakage sealing device and its construction method in view of the deficiencies in the prior art. When the gate cannot fall to the bottom, the hydraulic system is activated, and the piston in the hydraulic cylinder Stretch out and push the rubber sealing plate to the leaking part, which not only improves the sealing effect of the leakage sealing device at the bottom sill of the gate, prevents large water leakage of the gate, but also prolongs its service life. The protective cover can protect the hydraulic cylinder And the hydraulic pipeline plays a protective role to prevent the stones mixed in the impact of the water flow from damaging the hydraulic cylinder and hydraulic pipeline
