Embodiment
[0012] A method for strengthening the foundation of a cylindrical foundation by replacing water with air. A reserved pipe 3 is provided on the top sealing cover plate 2 of the cylindrical foundation 1. A one-way drainage port 4a is provided on the reserved pipe 3. The top sealing cover plate 2 There is a one-way drain 4b on the top, and the specific steps are as follows: 1) Firstly, inflate the cylindrical foundation 1 through the reserved pipe 3, and the water in the reserved pipe 3 is discharged through the one-way drain 4a on the reserved pipe 3; 2) ) When the air pressure in the reserved pipe 3 is higher than the atmospheric pressure, stop inflating, connect the reserved pipe 3 with the atmosphere, and the water body in the cylindrical foundation 1 passes through the one-way pipe on the top cover plate 2 of the pipe under the action of the pressure difference between the inside and outside of the pipe. 3) the foundation is consolidated repeatedly in this way, and the shallo...
