摘要
南水北调中线京石段应急供水工程南起石家庄古运河暗渠进口,北至北京团城湖,线路总长约307 km。工程设计和施工中的主要技术问题有:预应力钢筒混凝土管道(PCCP)工程技术问题;穿越五棵松地铁站、西四环快速路和立交桥的施工技术;大型渠道混凝土衬砌机的应用;大流量三向预应力输水渡槽设计与槽身混凝土裂缝防控措施。
The emergency water supply project for Beijing-Shijiazhuang section in Mid-route of South-to-North Water Transfer Project starts from the underdrain intake of the ancient canal in Shijianzhuang to the Lake Tuaneheng in Beijing with a total water transfer distance of 307 km. The key technical problems during both the design and the construction are ： engineering problems from pre-stress cylinder concrete pipe （PCCP） ; construction technique of crossing Wukesong Subway Station, Express Way and Cloverleaf Junctions of West Fourth Ring Road ; application of large canal concrete paver ; design of large discharge 3-D prestressed water conveyance aqueduct and the control measures for cracking of the aqueduct body.
