摘要
为降低软土地区深基坑支护施工的沉降位移,保证深基坑支护效果,设计一种软土地区深基坑支护施工技术,结合A工程概况,通过安装高稳定支护排桩提高支护强度,通过施打抗压支护钢板排除支护外部压力,通过埋设抗沉降止水帷幕进行深基坑排水,避免深基坑沉降,从而完成软土地区深基坑支护施工。施工结果表明,按照设计技术进行施工后各个基坑支护点位的沉降位移均低于施工允许沉降位移,支护效果较好,具有一定应用价值。
In order to reduce the settlement displacement of deep foundation pit support construction in soft soil area and ensure the support effect of deep foundation pit, this paper designs a deep foundation pit support construction technology in soft soil area. Combined with the general situation of project a, it improves the support strength by installing highly stable support piles, removes the external pressure of the support by driving compressive support steel plates, and discharges the deep foundation pit by embedding anti settlement water stop curtain to avoid the settlement of deep foundation pit, So as to complete the construction of deep foundation pit support in soft soil area. The construction results show that the settlement displacement of each foundation pit support point after construction according to the design technology is lower than the construction allowable settlement displacement, and the support effect is good, which has certain application value.
