Diversion tunnel blockage gate detecting system and detecting method
The invention belongs to the field of construction of hydraulic and hydroelectric engineering, and provides a diversion tunnel blockage gate detecting system simple in operation and capable of quickly detecting the sealing condition after the gate closing of a blockage gate, and a corresponding detecting method. The system comprises a water inlet tower, wherein a diversion tunnel is arranged in the water inlet tower; a blockage gate is arranged in an inlet of the diversion tunnel; and an operation room is arranged in the water inlet tower above the blockage gate. The system further comprises a detecting hole; the upper end of the detecting hole is communicated with the operation room, and the lower end is communicated with the diversion tunnel at the downstream of the blockage gate; and an openable blockage cover plate is arranged at the upper end of the detecting hole. The system is simple in operation, can immediately detect after the gate closing of the blockage gate, has no need to wait total discharge of water in the diversion tunnel, and has no need to pass through a longer tunnel at the downstream of the diversion tunnel, so that the needed detecting time can be largely shortened, the gate state inspection can be finished in a shortest time to quickly make such key decisions as renewed gate closing, and the plug construction difficulty caused by large water leakage at the later period is reduced.
