Earthquake-induced landslide lake rescuing drainage device and implementation method

The invention discloses an earthquake-induced landslide lake rescuing drainage device and an implementation method. The drainage device comprises a water inlet, a check valve, a check valve rubber gasket, a check valve rotating shaft, a water outlet, a valve, a valve rubber gasket, a valve rotating shaft, a valve clamping part, a valve clamping part rotating shaft, a telescopic pipe, a spiral telescopic bracket, a light high-strength and waterproof fabric, a female flange, a bump, a notch, a male flange, a screw rotating shaft, a thumb screw, a screw rod, a water filling nozzle and a water filling nozzle switch. The earthquake-induced landslide lake rescuing drainage device disclosed by the invention is composed of siphon parts which are telescopic and are easy to disassemble and assemble; and the drainage device is light in weight, high in strength and convenient for rescue workers to carry or for a helicopter to deliver. The rescue workers can conduct a drainage operation on a landslide lake which is formed by earthquake-induced landslide before large excavating machineries arrive, so as to reduce a water level and to avoid burst of the landslide lake as well as to provide time guarantee for the large excavating machineries, which arrive later, to excavate the landslide lake.
