At this time, the buoyancy of the water will make the floating rod 15 float up, and a plug 18 is placed in the water injection port 17, which can be used to inject water The box 14 acts as a seal to reduce the evaporation of water and cause inaccurate measurements. Then the anti-seepage wall block 13 is placed on the top of the placement table 12 and the box door 11 is closed. After standing for a period of time, the position of the marking line 16 on the surface of the float rod 15 is observed to determine whether the height of the float rod 15 has changed, so as to determine whether the anti-seepage property of the anti-seepage wall block 13 is qualified. In this step, the water tank 14 is connected to the anti-seepage wall block 13 and connected to the float rod 15, so that the float rod 15 can float on the water surface. By observing whether the position of the marking line 16 on the float rod 15 has changed, it is convenient to determine whether the water level has changed, so as to determine whether the anti-seepage property of the anti-seepage wall block 13 is qualified, so as to improve the convenience of water level measurement or observation.

[0028] like Figure 3 As shown, an electric heating tube 2 is fixedly connected to the top of the placement table 12; a pad 21 is fixedly connected to the top of the electric heating tube 2; when working, the electric heating tube 2 is energized to make it generate heat and then conduct the heat to the pad 21. The pad 21 is made of metal, which can make the heat conduction faster. At this time, the anti-seepage wall block 13 is placed on the top of the pad 21. The pad 21 conducts heat to the anti-seepage wall block 13, which can change the temperature of the anti-seepage wall block 13, and simulates the anti-seepage property of the anti-seepage wall block 13 under high temperature conditions. In this step, the electric heating tube 2 is connected to the pad 21 to conduct heat to the anti-seepage wall block 13 on the top of the pad 21, so as to increase the temperature of the anti-seepage wall block 13. It can simulate whether the anti-seepage property of the anti-seepage wall block 13 is qualified under high temperature conditions.

[0029] like Figure 3 As shown, a plurality of groups of heat conducting plates 3 are fixedly connected to the side wall of the electric heating tube 2; the top of the heat conducting plate 3 is in contact with the pad 21; during operation, when the electric heating tube 2 generates heat, the heat can be transferred to the heat conducting plate 3, and the heat conducting plate 3 is in contact with the pad 21 to transfer the heat to the pad 21.

[0030] like Figure 2As shown, a cold air machine 4 is fixedly connected to the top of the test box 1; an air outlet duct 41 is connected to the side wall of the cold air machine 4; an exhaust duct 42 is connected to the top of the test box 1; when working, starting the cold air machine 4 can allow cold air to enter the air outlet duct 41, and then the air outlet duct 41 blows the cold air into the inside of the test box 1 to cool down the inside of the test box 1, and can simulate the condition of testing the impermeability of the anti-seepage wall block 13 under low temperature. In this step, the inside of the test box 1 can be cooled down by setting the cold air machine 4 connected to the air outlet duct 41, and can simulate the condition of testing whether the impermeability of the anti-seepage wall block 13 is qualified under low temperature.

[0031] like Figure 5 As shown, a fixed frame 5 is fixedly connected to the inner wall of the test box 1; a plurality of guide plates 51 are fixedly connected to the side wall of the fixed frame 5; during operation, when the cold air flows from the air outlet duct 41 to the inside of the test box 1, it will pass through the guide plates 51, and the plurality of guide plates 51 are symmetrically arranged on both sides. At this time, the guide plates 51 can guide and disperse the passing airflow to expand the flow range of the cold air. In this step, the fixed frame 5 is arranged to connect the guide plates 51 to guide and disperse the cold air ejected from the air outlet duct 41, which can expand the flow range of the cold air and make the temperature in the test box 1 drop more evenly.

[0032] like Figure 4 As shown, a slide groove 6 is provided on the top of the water tank 14; a plurality of balls 61 are rotatably connected to the side wall of the slide groove 6; during operation, when the float rod 15 floats on the water surface, the surface of the float rod 15 will contact the plurality of balls 61, and when the float rod 15 moves, the balls 61 will rotate as the float rod 15 moves. In this step, by setting the balls 61 in contact with the float rod 15, the float rod 15 can rotate while it moves, thereby reducing the friction between the surface of the float rod 15 and the test box 1, making it easier for the float rod 15 to move and reducing the possibility of the float rod 15 getting stuck.

[0033] like Figure 5 As shown, the inner wall of the test box 1 is fixedly connected with an insulation layer 7; the insulation layer 7 is arranged on three sides; when working, when the electric heating tube 2 or the cold air blower 4 changes the temperature in the test box 1, the insulation layer 7 can insulate the inside of the test box 1 to reduce temperature loss. In this step, the insulation layer 7 can be arranged to insulate the inside of the test box 1, reduce temperature loss in the test box 1, and improve the temperature maintenance effect, thereby improving the stability of the test at different temperatures.

In this step, by setting the observation window 8, it is possible to directly observe whether the height of the float rod 15 changes, thereby reducing the need to open the box door 11 to cause internal temperature loss, so as to improve the convenience of observing data.

[0035] Working principle: When conducting an anti-seepage test on the anti-seepage wall block 13, connect the water tank 14 with the anti-seepage wall block 13, and then fill water into the water tank 14 through the water inlet 17. At this time, the buoyancy of the water will cause the floating rod 15 to float up. A plug 18 is placed in the water inlet 17 to seal the water tank 14 and reduce the evaporation of water that leads to inaccurate measurement. Then put the anti-seepage wall block 13 on the top of the placement table 12 and close the box door 11. After standing for a period of time, observe the position of the marking line 16 on the surface of the floating rod 15. The height of the floating rod 15 is determined to determine whether it changes, so as to determine whether the anti-seepage property of the anti-seepage wall block 13 is qualified. The electric heating pipe 2 is energized to make it heat up and then conduct the heat to the pad 21. The pad 21 is made of metal, which can make the heat conduction faster. At this time, the anti-seepage wall block 13 is placed on the top of the pad 21. The pad 21 conducts the heat to the anti-seepage wall block 13, which can change the temperature of the anti-seepage wall block 13. The anti-seepage property of the anti-seepage wall block 13 is tested under the condition of high temperature. When the electric heating pipe 2 is heated, the heat can be conducted to The heat conducting plate 3 is in contact with the pad 21 to conduct heat to the pad 21. At this time, the heat conducting plate 3 can increase the contact surface between the electric heating tube 2 and the pad 21. Starting the air cooler 4 can allow cold air to enter the air outlet 41, and then the air outlet 41 blows the cold air into the test box 1 to cool the inside of the test box 1. The impermeability of the anti-seepage wall block 13 can be tested under low temperature conditions. When the cold air flows from the air outlet 41 to the inside of the test box 1, it will pass through the guide plate 51. The multiple guide plates 51 are on both sides. Symmetrically arranged, the guide plate 51 can guide and disperse the passing airflow to expand the flow range of the cold air. When the float rod 15 floats on the water surface, the surface of the float rod 15 will contact multiple balls 61. When the float rod 15 moves, the balls 61 will rotate with the movement of the float rod 15. When the electric heating tube 2 or the air cooler 4 changes the temperature in the test box 1, the insulation layer 7 can insulate the test box 1 to reduce temperature loss. During the test, the height of the float rod 15 can be directly observed through the observation window 8 to observe whether it changes.
