Bucket type foundation reinforcing method by replacing water with air

Abstract

The invention relates to a bucket type foundation reinforcing method by replacing water with air. A reserved pipe is arranged on a sealing cover plate on the top of the bucket type foundation, and a one-way water outlet is respectively arranged on the reserved pipe and the sealing cover plate. The method comprises the following steps: (1) filling air into the bucket type foundation through the reserved pipe, so that water in the reserved pipe is discharged through the one-way water outlet on the reserved pipe; (2) when the air pressure in the reserved pipe is higher than the atmospheric pressure, stopping filling the air, and communicating the reserved pipe with the atmosphere, so that water in the foundation is discharged through the one-way water outlet in the cover plate on the bucket top under the action of the pressure difference between the interior and the exterior of the pipe; and (3) and repeatedly consolidating the foundation in this way, thereby reinforcing the shallow foundation. The bucket type foundation reinforcing method has the advantages of simple equipment and convenient construction. The bucket type foundation settlement, which is used as the shallow foundation in the regions with unfavorable geologic conditions, can enhance the bearing capacity, stability and safety of the bucket type foundation. Especially under deep water conditions, the method has the advantages of simple construction, short construction period and obvious economic benefit, and can effectively save the construction cost.

Description

Technical field

[0001] The invention relates to a method for strengthening the foundation of a cylindrical foundation by replacing water with air, which belongs to the foundation reinforcement treatment technology in port, ocean, water conservancy and bridge engineering. Background technique

[0002] At present, in port, ocean, water conservancy and bridge engineering, especially on silty soil, the settlement problem of the cylindrical foundation as a shallow foundation is the main problem in the application of the cylindrical foundation. In such areas with unfavorable geological conditions, it is difficult for the cylindrical foundation to meet the requirements of bearing capacity and stability. The present invention aims at solving these problems and improving the safety of the cylindrical foundation. Contents of the invention

[0003] The purpose of the present invention is to address the above existing problems, provide a method for strengthening the foundation of a cy...
