Energy Accumulating Cutting Technology in Steel Plate Cutting of Reservoir Gate

Abstract

Aiming at the problem that the gates of old reservoirs cannot be lifted normally, a gate energy concentrating cutting device was designed, which mainly studied the structure design of the cutting device, the structure design of the charge cover, the selection of the charge, the structure design of the detonation device, and the fixing method. The linear energy concentrating cutting technology is applied to the accident treatment after the reservoir gate is stuck, and realizes the rapid opening of the reservoir gate. The water outside the gate is diverted by the diversion tunnel so that the water pressure inside and outside the gate is balanced, and the stuck gate can be lifted smoothly. This technology can effectively solve the problem that the gates of old reservoirs cannot be lifted normally, and greatly reduce the construction difficulty and construction period. Through the ground cutting simulation test, it is verified that the designed energy concentrating cutting device can be reliably fixed on the gate steel plate, and its operation is simple and the construction is safe.
