However, during rainfall, rainwater easily accumulates on the surface of permeable concrete, and this water is difficult to drain, leading to slippery surfaces and affecting traffic safety. Therefore, testing the rainwater retention performance of permeable concrete is of great significance for improving its permeability and ensuring traffic safety.

This invention, through the combination of the electric telescopic rod, support plate, and positioning groove, can push the permeable concrete module to be tested upwards, so that the upper surface of the permeable concrete module is in contact with the bottom side of the connecting block. Opening the solenoid valve allows water from the water tank to be introduced into the surface of the permeable concrete module through the water guide pipe.
