本基坑为亳州地区软弱土场地-素填土地质条件下的基坑支护工程。根据基坑深度、周边建筑条件,采用了土钉墙支护。施工工艺为跟管钻进,二次高压注浆。通过信息化施工进行动态设计,有效限制了土体位移,在确保基坑侧壁的稳定性和安全性的同时,节约了工程造价。
The foundation pit is a soft soil site in Bozhou area - foundation pit supporting project under the condition of plain fill. According to the depth of the pit, the surrounding construction conditions, the use of soil nailing wall support. Construction technology for follow-drilling, secondary high-pressure grouting. Dynamic design through information construction, effectively limiting the displacement of soil, while ensuring the stability and safety of the sidewall of the pit, while saving construction costs.
