[0035] When the detection device is in use, the staff will fix the cylinder 2 with the test module 3 placed in it to the cabinet 1, and then press the switch 14 to transport water from the water inlet pipe 4 into the connecting pipe 6 through an external water pump, and start the pressure pump 5 to pressurize the water injected into the connecting pipe 6. The water enters the cylinder 2 from the seepage hole 19 on the sealing block 18 and comes into contact with the test module 3 to perform an anti-seepage test on the test module 3. The water in the connecting pipe 6 is heated by the heating mechanism to facilitate the detection of the test module 3 at different temperatures and to facilitate the detection of the test module 3.

[0037] When the detection device is in use, the heating tube 10 is started to heat through the controller 12. The heat emitted by the heating tube 10 is conducted to the connecting tube 6 through the support plate 9 to heat the water in the connecting tube 6. The U-shaped heating tube 10 facilitates uniform heat transfer and heating. The heated water is then detected by the temperature sensor 11. When heated to a suitable temperature, the temperature sensor 11 feeds back to the controller 12 to stop the heating tube 10.

[0040] The implementation principle of the anti-seepage detection device for concrete research and development in this embodiment is as follows: when the detection device is used, the staff will fix the cylinder 2 with the test module 3 placed on the cabinet 1, and then press the switch 14, and the water will be transported from the water inlet pipe 4 into the connecting pipe 6 through the external water pump, and the pressure pump 5 will be turned on to pressurize the water injected into the connecting pipe 6, and the water will enter the cylinder 2 from the seepage hole 19 on the sealing block 18, and the sealing gasket 15 will increase the sealing effect between the fixing ring 16 and the cylinder 2, which is convenient for the anti-seepage detection, and the butter applied will increase the sealing performance between the experimental module and the cylinder 2, reduce the leakage of water from the gap between the test module 3 and the cylinder 2, and improve the accuracy of the detection, and contact with the test module 3 to perform the anti-seepage detection on the test module 3;

[0041] When testing the impermeability of concrete modules at different temperatures, the controller 12 starts heating the heating tube 10, and the heat emitted by the heating tube 10 is conducted to the connecting tube 6 through the support plate 9 to heat the water in the connecting tube 6. The U-shaped heating tube 10 facilitates the uniform transfer of heat for heating, and then the heated water is tested by the temperature sensor 11. When heated to a suitable temperature, the temperature sensor 11 feeds back to the controller 12, so that the heating tube 10 stops heating.
