The rubber The bag 206 and the sealing ring 212 are tightly fitted with the inner wall of the water supply and drainage pipe 101. When the device needs to be disassembled, the water in the rubber bag 206 can flow out through the threaded groove 207 by removing the rotating screw. It should be noted that the water output of the threaded groove 207 is 4 times that of the water inlet groove 209. According to the characteristics of the clay soil that the volume of the expansive soil 211 expands sharply after being immersed in water and shrinks significantly after losing water, the expanded volume of the expansive soil 211 is smaller than the contracted volume at this time. The rubber bag 206 can be easily taken out, and then the expansive soil 211 can be replaced by opening the cover 205, so as to facilitate the next use.
