The water permeability can be detected according to the amount and speed of penetration. The upper part of the measuring tube 8 is elastically connected to the upper part of the connecting shaft 7 through a spring three 6.

At this time, the block 12 slides into the upper part of the measuring tube 8 under the squeeze of the spring 13 to fix it, then rotate the threaded rod 5 to drive the connecting shaft 7 to slide down, the connecting shaft 7 drives the block 12 to slide down, and the block 12 drives the measuring tube 8 to slide down until the lower end sealing ring 9 contacts the ground, then Clean water is discharged into the hose 3 through the water tank 4, and finally enters the measuring tube 8. The water permeability is measured by the height and time of the clean water falling. When shifting is required, the return blocks 17 at both ends can be pressed to squeeze the block 12 out of the measuring tube 8. At this time, the spring three 6 pulls the measuring tube 8 to slide up, and then the shift rod 14 slides to the left under the pressure of the spring two 15 to block the lower part of the sealing ring 9, and then moves to the next position, slides the shift rod 14 to the right to squeeze the spring two 15, and then slides the measuring tube 8 down again until it contacts the ground for measurement.
