Since the two second test boxes 44 have drive wheels 47 that roll in the first slide, and the curvature of the first slide is consistent with the curvature of the tube segment, the height of the two test boxes will adjust with the change of the curvature of the first slide when they move, thus placing the two second test boxes 44. 4.

The two second support beams 84 then drive the hydraulic cylinder 85 and the guide telescopic rod 86 to move. Then the hydraulic cylinder 85 and the guide telescopic rod 86 drive the pressure plate 87 to move to adapt to the size of the tube segment. When it moves to the position, the drive motor 91 stops, and then the hydraulic cylinder 85 is started. The drive end of the hydraulic cylinder 85 drives the pressure plate 87 to move towards the tube segment. At the same time, the drive end of the guide telescopic rod 86 extends to guide. After the pressure plate 87 presses the tube segment, the external water supply equipment is started. The external water supply equipment injects water into the test grooves 45 on the first test box 41 and the two second test boxes 44 through three hoses 48. Then the water pressure is maintained for a period of time to test the permeability of the tube segment.
