新华网河南频道10月22日电南水北调中线规模最大、技术难度最复杂的控制性工程之一的沙河渡槽工程目前正在紧张施工,总体工程量已完成约三分之二。其中由中国水电四局承建的沙河渡槽工程一标段预计在本月底实现贯通。在施工过程中,中国水电四局的工程技术人员克服渡槽预制件体型巨大、钢筋笼整体绑扎和吊装难度大、渡槽混凝土预制难度大等许多施工难点,所采用的U形双向预应力结构和现场预制架槽机架设施工方法,填补了国内外水利行业大流量渡槽设计及施工的技术空白。
沙河渡槽工程位于河南省鲁山县境内,于2009年12月30日开工建设,是国家南水北调中线工程的重要项目之一,是为帮助“南水”穿越平顶山境内的沙河、大浪河等河流“北上”而修建的大型水利设施,工程投资26亿元,全长11.938公里。
Xinhua Henan Channel October 22, the size of the middle route, Shahe Aqueduct, one of the technical difficulty controlling the most complex engineering project is being constructed, the overall project completed in about two-thirds. Shahe Aqueduct Project in four innings of China's hydropower construction tenders is expected to be achieved through the end of this month.Engineering and technical personnel in the course of construction, China's hydropower four innings to overcome the enormous size of the Aqueduct precast reinforced the cage overall lashing and lifting difficult, difficult Aqueduct precast concrete many construction difficulties, the U-shaped two-way prestressed structures and on-sitethe prefabricated frame slot machine erection fill technology gaps in the design and construction of a large flow of water conservancy industry at home and abroad aqueduct.
Shahe Aqueduct Project is located in Lushan County, Henan Province, started construction on December 30, 2009, is one of the important projects of the National Water Transfer Project, the Shahe, Big Wave River and other rivers through the territory of Pingdingshan for help "Nanshui" "north "and the construction of large-scale water conservancy facilities, engineering investment of 2.6 billion yuan, the total length of 11.938 km.
