[0035] Among them, the water inlet cylinder 33 is lifted upward by the hydraulic cylinder 31, and then the concrete test block 13 is placed directly on the surface of the infiltration net 12. Next, the hydraulic cylinder 31 pushes the water inlet cylinder 33 downward so that the lower end of the water inlet cylinder 33 is tightly against the surface of the concrete test block 13, which is convenient for taking and placing the concrete test block 13 and improving the detection efficiency.

[0036] At the same time, the water inlet pipe 36 injects water into the water inlet cylinder 33.
