南水北调沙河U形渡槽混凝土浇筑施工技术研究

介绍了南水北调中线沙河Ⅰ标预制渡槽混凝土浇筑施工技术。大型预制渡槽混凝土的浇筑质量是整个渡槽预制的核心部分,渡槽预制质量的优劣直接关系到整套预制工艺的合理性,经过认真分析、现场试验、多次总结、专家咨询等多种途径优化渡槽浇筑工艺。

Study on Technology for Concrete Placement of U-type Aqueduct over Shahe River, South-to-North Water Diversion Project

In this paper, technology for concrete placement of the precast aqueduct, Lot 1, the middle line of south-to north water diver- sion project, is described. The concrete placement quality of the large precast aqueduct is the core of the whole aqueduct precast. The quality of the precast aqueduct is related to the seasonality of the complete precast technology. In this project, the technology for the aq- ueduct concrete placement is optimized through a couple of manners such as careful analysis, site test. summaries and consultation, etc.
