摘要
对西北闹市区超厚高透水砂质地质无止水帷幕条件下深基坑施工技术进行研究,介绍在无止水帷幕情况下深基坑降水、支护和抗浮施工方法。通过不使用止水帷幕,采用合理的基坑降水、支护和抗浮方式,在保证工程安全的前提下,缩短工期,节约成本。
This paper studies the construction technology of deep foundation excavations in the ultra-thick and high-permeable sandy geology in the downtown area of Northwest China without water curtain,and introduces the construction methods of deep foundation excavation precipitation,support and anti-floating without water curtain.By not using water stop curtains,and adopting reasonable foundation excavation dewatering,support and anti-floating methods,on the premise of ensuring the safety of the project,shorten the construction period and save costs.
