The gas generating device comprises a gas cylinder A, a gas cylinder B, a flow guiding pipe, a branch pipe, a pressure gauge, a gas guiding pipe and a valve C; a sodium bicarbonate solution is contained in the gas cylinder A, an acetic acid solution is contained in the gas cylinder B, the gas cylinder A and the gas cylinder B are connected through the flow guidingpipe, the pressure gauge is arranged in the middle of the flow guiding pipe, and the branch pipe is connected to the flow guiding pipe; a gas inlet of the branch pipe is located above the liquid level, the inlet end of the gas guiding pipe is arranged in the gas cylinder A, the outlet end of the gas guiding pipe is connected with the bottom of the water tank, the valve C is mounted on the gas guiding pipe, a water inlet of the siphon is formed in the drilled hole in a slope, and a water outlet of the siphon is formed in the sealed water tank; and the drainage pipe is mounted on the top of thewater tank, the valve A is mounted on the exhaust pipe, the inlet end of the drainage pipe is connected to the bottom of the water tank, and the valve B is mounted at an outlet of the drainage pipe.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and in particular relates to an inflatable oscillating slope drainage system and method, which are suitable for drainage of water-rich cohesive soil slopes. Background technique [0002] my country has a vast territory, complex geological topography, and frequent geological disasters, among which landslide disasters pose a huge threat to human production and life. The occurrence of most landslide hazards is related to the change of groundwater level. The rise of the groundwater level leads to an increase in the bulk density of the landslide, a decrease in the effective stress of the sliding surface, and a decrease in the shear strength, which in turn leads to the instability of the landslide. For slopes, when the water level in front of the slope drops rapidly, the groundwater inside the slope seeps out of the slope, generating seepage force, increasing the sliding force, and causing...
