摘　　要：咬合桩作为一种支护围挡结构已得到广泛应用,介绍了咬合桩施工工艺及渗漏原因,分析了咬合桩施工阶段预防渗漏处理方法,对常见咬合桩渗漏类型进行分类,提出相关渗漏修补技术,结合工程实例对咬合桩渗漏修补技术进行验证,实践表明导管引流渗漏修补及引孔高压旋喷桩渗漏修补效果良好,可供相关设计及施工参考。As a kind of retaining structure,the occluded pile has been widely used.This paper introduces the construction technology and leakage reasons of occluded pile,analyzes the leakage prevention treatment methods in the construction stage of the occluded pile,classifies the common leakage types of the occluded pile,and puts forward the relevant leakage repair technology.Combined with the engineering example,the leakage repair technology of the occluded pile is verified.The results show that the repairing effect with the conduit drainage and pilot hole high pressure jet grouting pile is good,which can be used as a reference for design and construction.
