灌注桩、钢管桩连接及锚杆联合支护技术

COMBINED SUPPORTING TECHNIQUE OF CAST-IN-LACE PILE, STEEL TUBE PILE CONNECTION AND ANCHOR ROD

本文通过工程实例介绍了基坑支护技术。灌注桩构成连续墙起档土作用;钢管桩解决地下水位以下无法进行灌注桩施工的难题,起嵌固作用;锚杆起锚固作用;三者构成基坑支护体系。

By presenting case histories , this paper introduces the foundation pit supporting technique. The cast -in -place pile comprises a continuous wall with retaining action; the steel tube pile solves the difficult problem of impossibility of the constrction of cast梚n-place pile under the water table, which possesses an action of embedment and the anchor rods play the role of anchorage. All these three elements comprise the supporting system of foundation pit.
