S15标渠道混凝土机械衬砌施工试验

Construction Test to Canal Concrete Mechanical Lining in Beijing-Shijiazhuang S15 Bidding Section of the Middle Route in South-to-North Water Transfer Project

南水北调中线京石段应急供水工程全面开工,渠道机械衬砌施工工艺都在不断的试验阶段,结合渠道项目S15标衬砌试验的全过程,从衬砌基面清理,保温板及土工膜铺设,机械衬砌混凝土,混凝土的振捣、抹面、切缝等几个方面,对机械衬砌的施工工艺方法进行了总结归纳,确定了其中的工艺参数,为今后的类似工程提供借鉴和参考。

The Beijing-Shijiazhuang emergency water supply section comprehensively begins and the channel mechanical lining craft is m experimental stage. In the entire process of lining in S15 bidding section, it is summarized that the base cleaning, the heat preservation panel and the earth labor membrane pavement, the concrete inspires pounds, surface plasters and so on. The parameters are determined and this will provide reference for similar projects.
