Embodiment Construction

[0034] The specific implementation of the present invention will be described in further detail below with reference to the accompanying drawings.

[0035] Depend on Figure 1-Figure 9 As shown, when simulating a rainfall-induced landslide, the slope simulation version 7 corresponding to the contact surface required by the experiment is first loaded into the landslide simulation device 6, and then the overall control board 13 controls the landslide simulation device 6 to rise to a specified height. Then the water receiving tank 1 is pushed into the bottom of the landslide simulation device 6 , and then the overall control board 13 controls the landslide simulation device 6 to descend as a whole until it fits with the water receiving tank 1 . Fill the soil to be tested into the landslide simulator 6, turn on the fully automatic camera 15 through the main control board 13 to start recording, and the video recording will be transmitted to the remote terminal through the wireless ...

Abstract

The invention belongs to the technical field of mountain landslide detection, and particularly relates to a physical experiment device for exploring a rainfall induced landslide mechanism. The systemcomprises a water collecting groove, a water collecting groove water level control valve, water collecting groove rolling wheels, a rainfall system support body, a rotary rainfall simulation system, alandslide simulation device, a slope surface simulation plate, a hydraulic slope regulator, a flooding simulation device, a flooding device control door, a water pumping pump, a water conveying pipe,a total control plate, a base, a fully automatic camera, an electric wire, a rotating motor, a rotating shaft, a triangular flow guide plate, a guide pulley and a rope fixing post. The device can simulate two conditions including a rainwater induced landslide condition at different contact surfaces, different slopes and different rainfall quantities and a water soaking induced landslide conditionunder extreme conditions. The rainfall simulation system uses a creative rotary rainfall simulation system, and the uniform rainfall on a soil body is ensured. The whole experiment process can be recorded by the fully automatic camera, and can be transmitted to a remote terminal in a wireless way to be watched and stored.

Description

technical field [0001] The invention belongs to the technical field of landslide detection, and in particular relates to a physical test device for exploring the mechanism of rainfall-induced landslides. Background technique [0002] Landslides are one of the main forms of geological natural disasters, and rainfall is one of the main factors inducing landslides. With the increase of rainfall, the rainwater in the slope will generate great buoyancy on the surface soil of the slope, which will significantly reduce the formation pressure, resulting in a significant decrease in friction and landslides. At present, existing technologies and devices are difficult to provide simulation of precipitation-induced landslides under various conditions. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, adapt to actual needs, provide a kind of physical experiment device of exploring the mechanism of rainfall-induced...
