- 在分析了大型抗渗混凝土水池极易产生裂纹的原因基础上,文章从水池及混凝土结构的优化设计、抗渗混凝土质量控制、现场混凝土施工技术等方面介绍了该水池混凝土结构的防裂纹施工技术,确保了水池的质量。
The fifth bidding section of Pingchang-Yuanba pipeline in Sichuan Northeast to West Gas Pipeline Project has the length of 12.2 km and the maximum elevation difference of 456 m.Its pressure test is one of difficulties in the project construction.This paper analyzes the factors which should be considered in the pipeline section pressure test,discusses the optimal section partition for pressure test,and presents the construction scheme and measures of the subsection pressure test.Finally,the pipeline pressure test task is completed smoothly.2013,3(3): 75-77 收稿日期:2012-9-20DOI:10.3969/j.issn.1001-2206.2013.03.022作者简介:孙庆文(195-),男,山东章丘人,工程师,1987年毕业于中央电视大学化工机械专业,现从事工程项目管理工作。参考文献:
