谈地下水丰富的深基坑开挖施工技术

Discussion on construction technology of deep foundation pit excavation with rich groundwater

根据桂林市桃花江肖家船闸基坑开挖施工实例,主要对富水深基坑开挖施工方法、工艺进行阐述,提出了先止水、降水、排水,再进行土方开挖的方法,解决了富水深基坑开挖的边坡失稳、滑塌等问题,减少了基坑开挖边坡防护支撑的复杂工序,同时确保了施工安全和节约成本。

According to the foundation pit excavation construction examples of Xiaojia ship lock in Guilin Taohuajiang, mainly elaborated the construction method, technology of deep foundation pit excavation with rich water, put forward the method which first sealing, rainfall, drainage, then earth excavation, solved the problem of slope instability, slumping of deep foundation pit excavation with rich water, reduced the complex process of foundation pit exeavation slope protection supporting , at the same time ensured the construction safety and cost saving.
