摘要
沉管法工艺隧道,沉管预制在干坞内进行,叙述了干坞坞口结构施工技术,介绍了钢管桩墙加工与安装,钢管桩外辅助止水措施。针对施工难点和风险,采取相应技术措施,屏蔽了风险,保证了坞口止水效果,达到了预期的目标。
The immersed tube would be prefabricated in the dry-dock in the construction of tunnel by the immersed tube method. This article describes the construction technology of the dry-dock entrance structure; introduces an approach of installation and processing of the steel pipe pile wall, and an approach of auxiliary water-sealing measure to the outside portion of steel pipe pile. Corresponding technologies are applied to solve the difficulties and avoid the risks during construction, which guarantees the water-sealing effect of the entrance of dry-dock and achieves the prospected destination.
