[0008] With this setting, when in use, the swirl preventer can prevent air from entering the water pipe and interfering with water penetration, thereby ensuring the accuracy of the test. The on-off of the water pipe can be controlled by the valve to guide water along the glass measuring cylinder to the bottom of the chassis for penetration testing.

[0009] Preferably, a ring groove is formed on the lower surface of the chassis, the ring groove is filled with sealing putty, and the ring pressure plate is slidably inserted into the ring groove and presses the sealing putty.

[0018] Rotating the push rod downward will drive the push plate to move downward along the second support rod, so that the push plate can push the guide cylinder to move downward, and then the guide cylinder will push the counterweight block downward to press the counterweight block. The counterweight block with pressure applied is convenient for pressing the chassis more tightly, thereby facilitating the application of pressure to the sealing oil seal. At the same time, the counterweight block presses the pressure plate downward, and the pressure plate presses the corresponding pressure rods, which is convenient for pressing the ring pressure plate in multiple directions, and then it is beneficial for the ring pressure plate to squeeze the sealing putty in multiple directions at the same time, so that the sealing putty can more tightly seal the holes or cracks on the surface of the bridge, preventing the test water from leaking to the outside along the holes and cracks during the test, thereby improving the detection efficiency. Rotating the push rod upward can drive the counterweight block to reset, and then replace the pressure plate to reset. The operation is simple, time-saving and labor-saving.
