Abstract: A casing pipe extends in a vertical direction and is configured to be lowered into a borehole, and a mounting hole penetrates a side wall of the casing pipe; a push body is mounted in the mounting hole, a push groove is provided in one side, facing an interior of the casing pipe, of the push body, a flexible body is attached to an inner side wall of the casing pipe, one end of the flexible body is connected to the push body, the other end thereof is located in the casing pipe, and a sensor is mounted on the flexible body; and a propelling portion is connected to a driving mechanism and configured to be lowered to a position, opposite the push groove, in the borehole, and the driving mechanism drives the propelling portion to move towards the push groove.

Abstract: The present invention discloses a landslide experimental device for remotely controlling and simulating a constant seepage flow and weight load and an experimental method thereof in centrifuge test. The landslide experimental device includes a model box, a landslide device, a near-constant water flow control box, remote control devices and a water outlet pipe. The landslide device comprises a landslide model, a load balancing device, a weight storage device, an angle control panel and a tension bar. The remote control devices are arranged at the control box water outlet, at the control box water inlet, on the tension bar, on telescoping control sensors and on the weight storage device, respectively. With the present invention, the influences on the stability of landslide model with different landslide angles under the condition of the seepage flow and weight load can be simulated.
