Abstract
In order to ensure that the foundation of the pump station in karst areas can meet its subsequent operational needs,this article takes the drainage pump station in the urban river management project of Rongshui County as the engineering background,and combines the survey results to carry out foundation treatment design first.The effectiveness of foundation treatment is evaluated through methods such as drilling core method,compressive strength test,single pile static load test,water pressure test,and deformation prediction.The analysis results indicate that the geological conditions in the project area are relatively poor,and the geological problems mainly include bearing capacity issues,seepage deformation issues,and permeability issues.After screening the foundation treatment plan,the treatment method is determined as rotary jet grouting pile composite foundation;Combined with design and various experimental verifications,the rotary jet grouting pile composite foundation can effectively solve the problems of bearing capacity,permeability deformation,and water permeability,which has a good treatment effect and fully verifies the rationality of the rotary jet grouting pile composite foundation in this project,accumulating a certain theoretical basis for similar projects.关键词
