治理深圳河第四期工程截污管沉井施工技术

Construction technology of sunk-shaft for sewage interception pipe of Phase IV of Shenzhen River Regulation Project

本文结合治理深圳河第四期工程深圳侧截污工程沉井施工实际,阐述沉井施工过程的步骤、控制和相关措施。沉井挖土下沉是沉井施工中的一道非常重要的工序,因此,在实际下沉施工过程中采用了相关沉井施工技术并采取了严格的质量控制措施,避免了深基坑开挖支护过程中安全风险及会发生的相关费用,缩短了施工工期。

Combined with the actual construction of the sunk-shaft for the sewage interception pipe（ Shenzhen Side） of the Phase IV of Shenzhen River Regulation Project,the step,control and relevant measures during the construction are expatiated herein.The sinking-down of sunk-shaft is an important working procedure during the construction of it,thus the relevant construction technology for the sunk-shaft along with the strict quality control measures are adopted during the actual construction,and then not only the safety risks and the related costs are avoided,but the construction period is also shortened.
