摘要
水利工程施工过程中,增加地基承载力、改善地基稳定性、减小地基沉降作为项目工程的重点内容。钻孔灌注桩施工技术具备适用范围广、成桩效率高等优势能满足水利工程基础项目建设要求。基于此,依托水利工程项目实例,采用钻孔灌注桩施工技术进行项目作业。工程实际表明:钻孔灌注桩施工技术运用时通过在地下进行钻孔并将混凝土灌注至孔内形成桩体,能有效地增加地基承载力,改善地基稳定性,并且减小地基沉降。
During the construction process of hydraulic engineering,increasing the bearing capacity of the foundation,improving the stability of the foundation,and reducing the settlement of the foundation are the key contents of the project engineering.The construction technology of bored pile has the advantages of wide applicability and high pile forming efficiency,which can meet the requirements of water conservancy engineering foundation projects.Based on this,this article relies on examples of water conservancy engineering projects and adopts drilling and grouting pile construction technology for project operations.Engineering practice has shown that the application of drilling and grouting pile construction technology can effectively increase the bearing capacity of the foundation,improve the stability of the foundation,and reduce the settlement of the foundation by drilling underground and pouring concrete into the hole to form the pile body.
