南水北调中线滹沱河倒虹吸工程施工门架式管身混凝土皮带布料系统研究

滹沱河倒虹吸管身混凝土浇筑属于大体积混凝土浇筑。三孔一联的结构特点，大跨度的布置型式，使得混凝土浇筑布料成为关键控制点。经过分析研究，借鉴移动门吊结构，对通常采用的布料方式进行革新，较好地解决了这一难题。实践证明，自行研制的混凝土布料系统具有节省投资和高效、方便、适用的功效。可供同类型工程施工参考。

Research of the Concrete Distribution System in Placement at Hutuo River Inverted Siphon of South-to-North Water Transfer

Hutuo River's inverted siphon concrete placement belongs to big volume concrete placement. 3 holes running structural characteristics, big span arrange form, make concrete placement a key control point. By analysis, refer to the jenny, to improve the distribution system that usually adopted and have better solved this problem. The practice has proved that the concrete placement system has advantage of saving investment, high efficiency, convenient and applicable. It can be reference for same type project construction.
