南水北调中线工程的输水渠道以薄壁混凝土为主,其受地形、地质条件、气候及施工工艺等因素影响极易出现裂缝.混凝土浇筑前,参建单位进行了多次工艺试验,总结出一系列有效的防范与治理措施并广泛应用于渠道混凝土工程,成功保证了工程实体和外观质量,为类似工程的施工积累了宝贵的经验,具有一定的借鉴意义.
Concrete Crack Prevention and Treatment Test in South-to-North Water Diversion Project
The water transmission channel of the South-to-North Water Diversion Project is mainly thin-wall concrete,which is affected by terrain,geology,climate and construction technology,and is prone to cracks.Be-fore the concrete pouring,the participating units took several process tests,summed up a series of prevention and treatment measures and were widely applied,which successfully ensured the quality of the project entity and appearance,accumulated valuable experience for similar projects,and had certain reference significance.
