Two fixed handles 7 are fixedly provided on the outer walls on both sides of the detection cylinder 1, and the two fixed handles 7 are convenient for taking the utility model.

[0027] Working principle of this utility model:

[0028] Refer to the instruction manual Figure 1-3When the utility model is used, first, the bottom two ends of the strip concrete to be tested are overlapped on the supporting equipment. At this time, the detection cylinder 1 is placed on the top of the concrete, and the two support plates 16 are located on both sides of the bottom of the concrete. The two threaded rods 15 are rotated by the rotating block 18 to squeeze the extrusion pads 17 on the top of the two support plates 16 on the bottom outer wall of the concrete. At this time, the tension ring 10 is opened and moved downward. The tension ring 10 drives the positioning ring 9 downward through the tension spring 11 to apply downward pressure to the detection cylinder 1. The rubber sealing disk 3 at the bottom of the base 2 is tightly attached to the top outer wall of the concrete. The rubber sealing disk 3 is squeezed and deformed to fill the gaps on the concrete surface, which can effectively avoid The water in the detection cylinder 1 overflows from the surface of the concrete, which is beneficial to improving the detection efficiency of the concrete water permeability. After the detection cylinder 1 is fixed on the concrete surface, an appropriate amount of water is added to the detection cylinder 1. By observing the speed at which the water level in the detection cylinder 1 drops, it is convenient to understand the water permeability of the concrete. When the detection concrete is applied to the bottom of the pool, the water pressure on the concrete surface is high, so it is necessary to increase the pressure of the water for detecting the water permeability of the concrete. At this time, the sealing top cover 5 on the top of the fixing ring 4 is closed, and the gas pipe joint 6 on the top of the sealing top cover 5 is connected to the output hose of the air compressor, so as to apply pressure to the detection cylinder 1, increase the water pressure in the detection cylinder 1, and simulate the water permeability of concrete under high pressure environment.
