南水北调中线山庄河渠道倒虹吸是新卫段一标最大的水工建筑物,倒虹吸管身段共有九节,混凝土浇筑分两期施工,采用混凝土搅拌车水平运输和吊车垂直运输,配合混凝土吊罐及布料机送混凝土入仓,并采用串桶进行缓降。同时制定了严格的混凝土平仓、振捣和养护措施。该施工技术为管身段工程按节点工期和工程质量要求完工奠定了基础。
In the middle section of South-to-North Water Diversion Project, the inverted inverted siphon is the largest hydraulic structure of Xinwei section with a total of nine inverted siphon sections. The concrete pouring is carried out in two phases. The horizontal transport of concrete mixer and vertical transport of the crane are used together with the concrete hanging tank and Conveyor delivery of concrete warehousing, and the use of string bucket slow down. At the same time developed a rigorous concrete positions, vibration and conservation measures. The construction technology for the body section of the project by node duration and project quality requirements laid the foundation for completion.
