【摘要】 伴随环境治理需要,很多时候需在河涌中新建大型污水渠箱。渠箱如何穿越重要的跨河建构筑物有时是工程能否顺利推进的关键所在。以鸭涌河综合整治工程为例,分析过澳边界跨河供水管存在的难题,提前对现有供水管进行保护,改渠箱为钢管,变开挖为非开挖,采用一次性闷顶方式顺利顶进,可为类似工程提供参考。更多还原

【Abstract】 With the need of environmental governance, it is necessary to build a new large sewer canal box in the river. How does the canal box cross the important river crossing structures is sometimes the key to the smooth progress of the project. Taking the Yachong River Comprehensive Regulation Project as an example, the difficulties of the cross-river water supply pipe on the border of Macau are analyzed. The existing water supply pipe is protected in advance. The canal box is changed into the steel pipe. The excavation is changed into the trenchless. The one-time direct pipe jacking method is adopted, which can provide reference for similar projects.更多还原
