With the expansion of the application scope of waterproofing membrane, higher requirements are put forward for its performance during long-term use, especially in complex and extreme environments, it is required to have good acid resistance and good waterproof performance.

[0024] Working process: the waterproofing membrane is laid flat on the ground, and the limiting ball 28 is engaged with the groove 27. At this time, one end of the ball rack 24 extends out of the shell 23, so that the ball 25 directly contacts the waterproofing membrane and the counterweight water retaining frame 4 is separated from the waterproofing membrane, so that the movable support part 6 provides movable support for the counterweight water retaining frame 4. After the counterweight water retaining frame 4 moves above the membrane, as the handle 26 is pulled, the handle 26 pulls the ball rack 24, so that the ball rack 24 drives the ball 25 to move into the shell 23.

At this time, the counterweight water retaining frame 4 falls and is pressed onto the surface of the waterproofing membrane. At this time, the personnel injects the space enclosed by the counterweight water retaining frame 4 on the waterproofing membrane. During water operation, the counterweight water retaining frame 4 uses its own weight to press on the waterproof coiled material to prevent water from flowing out from between the counterweight water retaining frame 4 and the waterproof coiled material, so that a water storage layer is formed above the waterproof coiled material and the counterweight water retaining frame 4. The lifting part 8 drives the driving motor 9 to descend, so that the acid rain temperature measuring part 11 and the floating ball positioning part 12 are close to the water storage layer on the waterproof coiled material, and then the first motor 14 drives the first screw 15 to rotate, and the first screw 15 drives the first slide 16 to move along the first guide frame 13, so that the hydraulic measuring and shifting assembly 17 moves, and then the hydraulic measuring and shifting assembly 17 drives the hollow floating ball assembly 18 to enter the water storage, and in the process of the driving motor 9 rotating by driving the rotating frame 10, the acid rain temperature measuring part 11 and the floating ball positioning part 12 rotate around the rotation center of the driving motor 9 At this time, the hollow float assembly 18 measures the liquid level at different positions.

The second motor 32 drives the second screw 33 to rotate. The second screw 33 drives the second slide 34 to move along the second guide frame 31, thereby driving the box 36 to move. The first electric telescopic rod 35 is used to drive the box 36 to rotate to adjust the direction of the first semicircular frame 39 and the second semicircular frame 40. Under the drive of the second electric telescopic rod 37 to the connecting frame 38, the first semicircular frame 39 moves, thereby adjusting the distance between the first semicircular frame 39 and the second semicircular frame 40. At this time, the first semicircular frame 39 and the second semicircular frame 40 stir the water storage layer on the waterproof membrane to After the agent for adjusting the pH value is added to the water storage layer, the agent is quickly and evenly dissolved in the water to simulate the situation where acid rain falls on the roll material. The first semicircular frame 39 and the second semicircular frame 40 are separated from each other to enhance the stirring effect on the water. After the two groups of temperature sensors 41 are in contact with water, the temperature measurement operation is carried out. As the counterweight water retaining frame 4 is pressed on the waterproof roll material, the anti-skid pressure block 22 is pressed on the waterproof roll material, the first active telescopic frame 19 drives the first pressure sensor 20 to move, and the moving first pressure sensor 20 drives the pressure frame 21 to move, and the pressure frame 21 drives the anti-skid pressure block 22 to move, so that the moving anti-skid pressure block 22 pulls the waterproof roll material. At this time, the waterproof roll material is tensioned, so that the waterproof roll material can be detected for water leakage when it is tensioned.
