Problems solved by technology

[0002] In order to study the thermal pollution of urban land subsidence and urban geology, it is necessary to test the heat transfer and flow properties of water-containing porous media materials. Among the existing technologies, the patent No. 94103302.3 is the invention patent of "Rapid Measurement Method for Weak Aquifer Permeability Coefficient". It is a measurement technology for the hydrogeology and permeability coefficient of weak aquifers; the invention patent of "Method and Device for Monitoring the Flow of Seawater to Freshwater Aquifers in Coastal Cities" with the patent number of 01806143.5 can only monitor the movement of seawater to cities
Neither of the two patented technologies can complete the test of heat transfer and flow properties of porous media after water is contained

Embodiment Construction

[0010] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, the present invention includes: test box 1, water injection pipe 2, water supply tank 3, solenoid valve 4, heating water tank 5, water injection pump 6, D stop valve 7, heating device 8, A stop valve 9, B stop valve 10 , C shut-off valve 11, return pump 12, flow meter 13, water collection tank 14, filter screen 15, water inlet pipe 16, filter water tank 17, drain pipe 18, thermocouple element 19.

[0012] The test box body 1 is filled with the porous medium material to be tested, and multi-layer mesh thermocouple elements 19 are arranged in the material. One end of water inlet pipe 16 communicates with running water, and the other end stretches in the heating water tank 5, and is connected with float valve. A heating device 8 with temperature control is installed in the heating water tank 5 , and an out...
