[0036] After the overall device is placed in the well pit, the flat mechanism is manually started to scrape the soil at the bottom of the well pit, and then the pipeline assembly in the resin water meter well shell is assembled by hand, and then the resin water meter well shell is placed in the guide frame 101, so that the four corners of the resin water meter well shell correspond to the corners of the four guide frames 101 respectively. After the resin water meter well shell is placed in the guide frame 101, the lifting mechanism is started manually, and the lifting mechanism drives the resin water meter well shell to move downward. Initially, the rotating plate 204 is in a vertical state, the rotating plate 204 drives the limiting rail 205 to be in an initial state, the limiting rail 205 drives the elastic wedge block 206 to be in a vertical state, the elastic wedge block 206 is in contact with the teeth on the upper side of the limiting ratchet wheel 207, and the bottom rear edge of the resin water meter well shell is in contact with the adjacent swing rod 203 and extrudes the swing rod 203 in the moving process.
