However, it is always technically difficult to measure the pore water pressure of frozen soil. Although it is common to measure frozen soil pore water pressure changes, in the prior art there has not yet been a specific standard or device for measuring frozen soil pore water pressure changes, as these substances contaminate the soil. Therefore, there is currently a need for a device that measures pore water pressure changes in frozen soil.

The inner diameter of the medium tank pipe is 0.05 to 0.08 mm, the medium tank pipe uses a hydrophilic material, and the medium tank pipe is filled with interfacial water. The surface of a hydrophilic material interacts with water molecules with a micron-level interaction force, and the water within this range is generally called interfacial water, and the physical and mechanical properties of the interfacial water are significantly different from those of bulk water. Therefore, by setting the inner diameter of the medium tank pipe to 0.05 to 0.08 mm, the medium water filled in the medium tank pipe becomes interfacial water, and an air cavity is formed under negative pressure. The lower limit of the force is lowered, the measurement range of the device is effectively expanded, and the use of interfacial water as the force transmission medium effectively avoids the problem of environmental pollution caused by the use of other media.

The beneficial effects of the present invention compared to the prior art are as follows. The present invention has a rational design of the structure as a whole, and by combining the special structure and material of the medium tank piping with the interfacial water, water bubbles are likely to occur in the medium, resulting in measurement failure and measurement range reduction.

It is effectively avoided, and combined with the structure of the whole device, it enables good sealing performance, which makes the measurement range wider for practical application.
