[0036] 1. The operation process of testing the water resistance of the waterproof roll material is as follows:

[0037] Firstly, the waterproof roll material 23 is cut to the size and shape of the inside of the water permeable disc 7, so that it can be placed flat in the water permeable disc 7. After the waterproof roll material 23 is placed, the annular pressing plate 9 is placed in the water permeable disc 7, so that it is pressed on the waterproof roll material 23. The air compressor 3 is started, and the air valve 4 on the air pipe is opened. The air cylinder 11 of the telescopic mechanism is controlled to be elongated through the control panel 12, so that the annular pressing piece 10 is tightly pressed on the annular pressing plate 9, and the fixing of the waterproof roll material 23 is completed.

The water pump 18 is started through the control panel 12, and the water pressure and the pressure duration are set. The test is started. The water pump 18 draws the water in the water storage tank 17, and delivers the water to the water permeable hole 8 through the water supply pipeline 19. The water flows into the water permeable disc 7 through the water permeable hole 8 for testing. After the test is completed, the water supply valve 5 is closed, the drain valve 6 is opened, and the telescopic mechanism is controlled to be retracted upward through the control panel 12. The annular pressing piece 10 is moved out to the upper side of the water permeable disc 7, and then the annular pressing plate 9 and the waterproof roll material 23 are taken out. The next group of waterproof roll material samples can be tested. After all the tests are completed, the air compressor 3, the water pump 18 and the water supply valve 5 are closed.

[0038] 2. The operation process of testing the water resistance of the waterproof blanket is as follows:

[0039] First, the waterproof blanket sample is loaded into the hopper 134 of the permeameter 13, the permeameter 13 is placed on the workbench, the exhaust port 132 and the water outlet 133 of the permeameter 13 are aligned above the drain groove 14, so that the water flow can flow back into the water recovery tank 21; then, the connecting pipe 15 is connected to the water inlet 131 of the permeameter 13, the water supply valve 5 corresponding to the connecting pipe 15 is opened, the other water supply valves 5 and the drain valve 6 are closed; then, the water pump 18 is started through the control panel 12, so that the water in the water storage tank 17 flows into the permeameter 13, the exhaust port 132 is observed, when the exhaust port 132 has water flowing out, it indicates that the air in the permeameter 13 has been exhausted, at this time, the valve of the exhaust port 132 is closed, the water pressure and the pressurization time are set through the control panel 12, and the water resistance test of the waterproof blanket is carried out. After the test is completed, the water supply valve 5 is closed, the waterproof blanket sample in the hopper 134 is replaced, the water supply valve 5 and the valve of the exhaust port 132 of the permeameter 13 are opened again, when the exhaust port 132 has water flowing out, the above steps can be repeated to continue the test, and when all the tests are completed, the water pump 18 is closed, the water supply valve 5 is closed, and the sample in the hopper 134 is taken out.

[0040] In the above test process, when there are too many sundries in the wastewater generated by the test, in order to avoid pollution of the inside of the water storage tank 17, the drain valve 6 can be kept closed, and the drain groove 14 is used to block the sundries, at this time the wastewater generated by the test will stay on the workbench 25, but after the test is completed, the wastewater on the workbench 25 needs to be wiped off with a dry cloth.
