Earthquake-induced landslide lake rescuing drainage device and implementation method

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of water discharge and emergency rescue, in particular to an emergency water discharge device for an earthquake dammed lake and an implementation method. Background technique [0002] China is a country severely affected by earthquakes with high frequency, high intensity, shallow focus and wide distribution. If a strong earthquake causes landslides, landslides, and dams, the river will be interrupted and a barrier lake will be formed. The water level of the barrier lake may rise rapidly. Once the barrier lake breaches, it will form a flood peak downstream, which is as destructive as the earthquake disaster itself. For highly dangerous barrier lakes, manual excavation, blasting, etc. must be used to drain the water and gradually lower the water level to avoid major floods. However, after the strong earthquake, the casualties were serious and the roads were damaged and interrupted. It was very difficult for ...

Problems solved by technology

However, after the strong earthquake, the casualties were serious and the roads were damaged and interrupted. It was very difficult for the rescuers to transport the large-scale excavation machinery to the barrier lake, and it took a long time. find a good solution
