1. A test device for simulating deposition of filling media in karst caves and occurrence of tunnel intermittent water and mud inrush disasters, comprising
a mixing tank,
a water tank,
a water collection tank and a plurality of depositing tanks, wherein an outlet of the mixing tank is connected to one end of a pipe, another end of the pipe extends to one end of the water tank, the plurality of depositing tanks are arranged under the water tank at intervals, the water collection tank is arranged at another end of the water tank, and a position within the water tank at an inlet of each of the plurality of depositing tanks is configured to receive detachable baffles, wherein the detachable baffles have different heights and/or square holes of different size in the middle, and
a valve, a flowmeter and a recorder arranged on the pipe, wherein
the valve is configured to control flow rate and flow volume of a mud-water mixture being poured in and flowing out of the mixing tank, the flowmeter is configured to measure an outflow per unit time of the mud-water mixture flowing out the mixing tank, and the recorder is configured to record a profile of the flow rate of the mud-water mixture flowing out of the mixing tank per unit time, and
each of the plurality of depositing tanks respectively is connected with the water tank by a flange structure, and a permeable plate and permeable stones are arranged at a bottom of each of the depositing tanks respectively, a switch is arranged on one side of each of the plurality of depositing tanks respectively, an articulated joint connected with a tube is arranged on another side of each of the plurality of depositing tanks respectively, a control valve is arranged between the articulated joint and a corresponding one of the plurality of depositing tanks, and a camera is arranged on the tube and configured to capture images of a process of an occurrence of a simulated water and mud inrush disaster in the corresponding one of the plurality of depositing tanks respectively.
