摘要
严寒地区桩锚深基坑越冬保温防护关系到整个越冬基坑的安全性、可靠性和稳定性,是基坑越冬施工的关键技术问题,因未进行保温防护使深基坑遭受冻害、产生严重变形的现象屡屡发生。依托长春市地铁2号线西兴站装配式车站基坑工程,通过理论分析和现场施工相结合的方法,研究了严寒地区桩锚深基坑越冬保温防护技术的施工流程、施工工艺和关键操作要点,并对采用桩锚深基坑越冬保温防护技术的潜在问题进行分析,得到相应结论。
The safety, reliability and stability of the whole winter foundation pit are the key technical problems in the construction of the winter pit. The failure of the deep foundation pit is caused by the heat preservation protection. The phenomenon of deformation often occurs. Based on the combination of theoretical analysis and field construction, this paper studies the construction process, construction technology and key operation of wintering insulation technology of deep foundation pit in deep and cold area of Changchun Subway Line Ⅱ Xixing Station.
