[0027] The transparent display box body 1 is made of transparent acrylic material or transparent glass. A detachable box cover 2 is buckled and installed on the top of the transparent display box body 1. The elastic pressure regulating members 3 are arranged in a 5×5 array on the box cover 2. The elastic pressure regulating member 3 includes a pressure regulating end and an extrusion end. The extrusion end extends downward into the interior of the transparent display box body 1, and the pressure regulating end extends upward to the top of the box cover 2. The pre-pressure of the entire elastic pressure regulating member 3 can be adjusted through the pressure regulating end. The interior of the transparent display box body 1 is divided into at least two independent comparison partitions 4. The comparison partitions 4 can be formed by arranging partition boards inside the transparent display box body 1 for isolation, or by placing transparent partition cylinders in the transparent display box body 1. A filling port 5 is arranged at the top of the comparison partition 4, and a comparison soil sample is filled into the interior of the comparison partition 4 through the filling port 5. A liquid leakage port 6 is arranged at the bottom of the comparison partition 4 for subsequent comparison of the water seepage of the comparison soil samples.

[0028] The process of soil sample comparison is as follows:

[0029] Place equal weights of underlying saline-alkali soil at the bottom of the comparison partition 4 through the filling port 5, and drive the pressing plate assembly 7 to press down through the elastic pressure regulating member 3 to compact the underlying saline-alkali soil. Scales are arranged on the side walls of the comparison partition 4 to ensure that the thickness of the underlying saline-alkali soil in each comparison partition 4 is equal. Then add equal weights of comparison soil samples into the comparison partition 4 through the filling port 5, for example, one comparison soil sample is mixed with a stabilizer, and the other comparison soil sample is mixed with clear water. Then drive the pressing plate assembly 7 through the elastic pressure regulating member 3 to compact the comparison soil samples equally and maintain static pressure for at least 5 minutes. Then add equal weights and heights of top-layer saline-alkali soil into the comparison partition through the filling port 5, and then water can be filled into the comparison partition equally and at a constant speed through the filling port 5. At the same time, observe the water seepage process through the transparent display box body 1, and observe the water seepage volume and water seepage rate of different comparison soil samples through the liquid leakage port 6 at the bottom of the comparison partition 4.

[0033] A rotation slot is arranged at the top of the box cover 2, and the rotation slot is rotationally clamped with the lifting adjustment nut 34, so that the lifting adjustment nut 34 can rotate on the top of the box cover 2 but cannot move axially. By rotating the lifting adjustment nut 34, the pressure regulating rod 32 is further driven to lift. A boss is arranged at the bottom end of the pressure regulating rod 32. When the pressure regulating rod 32 rises, it drives the boss to squeeze the spring 31, causing the spring 31 to compress. By controlling the rising stroke of the pressure regulating rod 32, the compression amount of the spring 31 is further adjusted, and then the pressing plate assembly 7 is installed at the bottom of the pressing plate 33. Then, some of the lifting adjustment nuts 34 are loosened, and by controlling the number of loosened lifting adjustment nuts 34, the pressure exerted by the pressing plate 33 on the pressing plate assembly 7 is adjusted.
