盾构下穿河道施工技术探究

Wear River Construction Technology to Explore Under The Shield

盾构下穿河道施工技术具有一定的风险性和施工难度,施工中需要做好盾构穿越过程中隧洞背后填充和管片防水工作,并通过合理控制盾构掘进过程中的各项指标来有效降低施工难度和施工风险。文章以南水北调东干渠工程9#盾构井~8#盾构井盾构区间施工为切入点,探讨穿越该区间河道的施工技术。

Under the shield in river channel construction technology has certain risk and difficulty of construction,the construction of the need to be behind the shield through the tunnel in the process of filling and segment waterproof,and through the reasonable control of shield tunneling in the process of the indicators to effectively reduce the construction difficulty and risk.Water flows east of the project based on the 9#shield well^8#shield well shield construction as the breakthrough point,discusses through the channel between the construction technology.
