Each single cylinder 11 is connected to a set of upper detection boxes 2, and the single cylinder 11 and the upper detection box 2 are detachably connected. The single cylinder 11 is a cylindrical tube with a stable base 12 at its lower end. In this embodiment, the stable base 12 is a rectangular flat plate, which facilitates the placement of the lower detection box 1 on the ground. A stepped cylinder 13 with a larger diameter is coaxially provided at the upper end of the single cylinder 11. The stepped cylinder 13 is also a cylindrical tube, and its upper end is connected to a lower connecting flange 14, which connects to the upper detection box 2.

A transparent observation window 5 is provided on the side wall of the single cylinder 11, which runs vertically. The transparent observation window 5 allows for easy observation of the permeation water inside the single cylinder 11.

The inner and outer diameters of the sample cylinder 22 are the same as those of the stepped cylinder 13. The upper connecting flange 23 is connected to the lower end of the sample cylinder 22. When the upper detection chamber 2 is connected to the lower detection chamber 1, it is fixed by bolts through the lower connecting flange 14 and the upper connecting flange 23. A water filling connector 24 and a valve are connected to the side wall of the water storage tank 21 to facilitate the addition of water to the water storage tank 21.

The lower sealing sleeve 32 is also cylindrical and is fitted and fixed inside the stepped cylinder 13 and abuts against the inner wall of the stepped cylinder 13. When the upper detection box 2 and the lower detection box 1 are connected, the end faces of the upper sealing sleeve 31 and the lower sealing sleeve 32 abut against each other.

[0028] The upper detection box 2 and the lower detection box 1 are equipped with sample chambers 33 for placing test samples.

The lifting push rod 42 is configured as a threaded rod, with its upper end passing through the top plate of the water storage tank 21 and threadedly connected to the top plate of the water storage tank 21. The rotating handle 43 is connected to the upper end of the lifting push rod 42 and is used to rotate the lifting push rod 42 to adjust the height of the piston disc 41, thereby adjusting the pressure inside the water storage tank 21.

[0030] The implementation principle of this application embodiment is as follows: During testing, the device is brought to the test site, the test target is sampled, the sample is placed in the sample chamber 33, and the sample is placed in the appropriate stepped groove in the sealing component 3 according to the sample size. Then, the upper test box 2 is installed on the lower test box 1 and tightened.

The permeation test experiment is started, and the permeation of the test sample is observed through the transparent observation window 5 and the scale 6.
