Device and method for simulating corrosion of concrete soaked by underground water at different temperatures

The invention discloses a device and a method for simulating corrosion of concrete soaked by underground water at different temperatures. The device comprises a corrosion-resistant water tank with a cover and a constant-temperature heater, the corrosion-resistant water tank with the cover comprises a heating water tank and a soaking water tank; the soaking water tank is arranged in the heating water tank, and heating water used for conducting water bath heating on the soaking water tank is contained in the heating water tank. A corrosive solution is contained in the soaking water tank, and a concrete test block is placed in the soaking water tank and immersed in the corrosive solution; the constant-temperature heater is arranged in the heating water tank to heat the heating water, so that the corrosive solution and the concrete test block are indirectly heated at constant temperature. The device for soaking the concrete in the corrosive solution under water bath heating is adopted, so that the test cost can b
