有关咬合桩在基坑支护中的应用

The Application of Secant Pile in Foundation Pit Supporting

在基坑开挖施工期间,为保证基坑支护安全,必须对基坑采取一定的支护措施。基坑支护设计与施工应综合考虑工程地质与水文地质条件、降排水与止水措施,保证基坑及周边建筑安全。本文主要介绍咬合桩在基坑支护中较好的止水效果:相对高压旋喷桩及搅拌桩而言,咬合桩在基坑支护中的止水效果更好,更适合对止水效果要求高的工程项目。

During the excavation,in order to ensure the safety of foundation pit,some foundation supporting measures should be taken. The engineering geological and hydrogeological conditions,drainage and waterproof measures should be considered in the foundation pit design and construction,to ensure the security of foundation pit and surrounding buildings. This paper mainly introduces good sealing effect of secant pile in foundation pit,and sealing effect is better than high pressure jet grouting pile and stirring pile. So it is more suitable for high requirements on the sealing effect.
