The invention provides a pouring and injection integrated indoor testing device and method for monitoring underground water seepage and precipitation. The pouring and injection integrated indoor testing device comprises a visualized round model barrel; a plurality of water penetrating plates are inserted into the visualized round model barrel; a rectangular soil sample box is formed between the water penetrating plates; a soil sample is stored in the rectangular soil sample box; a recharge well and a water precipitation well, which are connected with a water supply device, are inserted into the soil sample, and can be used for pumping and injecting water layer by layer; a pore water osmotic pressure sensor, a soil pressure sensor, a displacement sensor and a water pressure metering instrument, which are connected with an information analysis system, are buried in the soil sample; a water level variable water tank chamber is formed between the water penetrating plates and the round model barrel; and the water level variable water tank chamber is used for simulating a real working condition by controlling the height of a water level through flow control valves mounted on the recharge well and the water precipitation well. |
