深基坑土钉墙支护施工时,因击入钢管长度过长容易造成弯曲,从而影响支护体强度及稳定性。在综合分析支护体构造及施工成本的基础上,提出了深基坑炮锤击入钢管土钉墙支护施工技术,摆脱常规支护的构造形式,提高了施工功效,并对其工作原理、施工工艺流程、关键技术特点进行了深入研究。
Soil nailing wall construction of deep foundation pit, due to the length of the pipe into the tube is likely to cause bending, thus affecting the strength and stability of the support. Based on the comprehensive analysis of the support structure and the construction cost, the paper puts forward the construction technology of the deep foundation pit gunneling into the soil nailing wall of the steel pipe, gets rid of the conventional support structure and improves the construction efficiency, , Construction process, the key technical characteristics of an in-depth study.
