Then add water into the water storage mechanism, and the water permeability test of the concrete pavement brick can be carried out. Through the setting of the sealing ring 202, the sealing between the water storage mechanism and the pavement brick can be realized, and the water in the water storage mechanism is prevented from flowing out through the surface of the pavement brick, thereby improving the accuracy of the test.

The thickness of the sealing ring 202 is greater than the thickness of the positioning ring 301. The sealing ring 202 is inserted into the interior of the positioning ring 301. Through the guiding mechanism, the positioning ring 301 and the top plate 102 are kept in longitudinal limit, and at the same time, the connecting ring 201 is clamped between the positioning ring 301 and the top plate 102, so that the sealing ring 202 will not be displaced between the top plate 102 and the paving brick, and the sealing ring 202 can effectively prevent the water in the water storage mechanism from flowing out through the surface of the paving brick, thereby improving the stability of the use of the sealing ring 202.

[0025] Among them, the guiding mechanism includes a limiting rod 402. A first insertion hole 401 is opened at the top end of the positioning ring 301.
