1. An experimental device for simulating a subsurface erosion process, comprising a constant-pressure water supply device, a subsurface erosion generator, and a water-soil collection device, wherein the constant-pressure water supply device and the subsurface erosion generator communicate with each other by a pipeline;
the constant-pressure water supply device is used to simulate a natural water flow in the subsurface erosion;
the subsurface erosion generator is used to carry sand and display the occurrence process of water-soil subsurface erosion; and
the water-soil collection device is used to collect soil and water loss data required for an experiment;
characterized in that:
the constant-pressure water supply device comprises a water tank, a top of the water tank is provided with a water inlet end, a bottom of the water tank is provided with a water outlet end, and the water outlet end of the water tank is connected to the subsurface erosion generator by a pipeline;
the subsurface erosion generator comprises a model box for soil loading and a water inlet pressure measuring box which are in communication with each other, and the model box for soil loading is located above the water inlet pressure measuring box;
the model box for soil loading and the water inlet pressure measuring box are separated by a perforated partition plate, and an upper end of the perforated partition plate is covered with a gauze mesh;
a bottom of the water inlet pressure measuring box is provided with a water inlet end, and the water inlet end of the water inlet pressure measuring box communicates with the water outlet end of the water tank by a pipeline;
a side wall of the model box for soil loading is provided with a water outlet end, and the water outlet end of the model box for soil loading extends into the water-soil collection device by a pipeline; and
a pressure gauge is connected to a side wall of the water inlet pressure measuring box by an elbow joint.
