福建永春县煤炭大厦基坑支护

Retaining and Excavation of the Coal Building in Yongchun City

单独用单管高压旋喷桩对基坑进行围护 ,在福建省内应用较少 ,本文通过一个由单管高压旋喷桩结合静压注浆对基坑围护的成功实例 ,指出单管高压旋喷桩在基坑挡土止水中起着重要作用 ,文中同时论述了在施工中所遇到的问题 。

One-pipe high pressure jet grouting pile play an important role in retaining soil and seal water for a pit foundation excavation.A successful engineering case for using this method to retain pit foundation is introduced in this paper.
