管道土建工程的冬季施工措施

Winter Construction Measures of Pipeline Civil Engineering

在管道工程建设中,由于工期的需要有时不得不在冬季进行施工。当室外平均气温连续5 d稳定低于5℃时,应采取相应的冬季施工措施。文章结合大量的工程实践,主要从土建工程冬季施工的准备、冬季施工的主要技术质量控制、冬季施工中混凝土的常见质量通病和预防措施等方面进行了阐述。

For pipeline construction,sometimes winter construction has to be carried out because of time limit requirement.While the outdoor average temperature in five sequential days is steadily lower than 5℃,then winter construction measures should be taken.Based on a great deal of engineering practice,this paper describes winter construction preparation,key technical and quality control,common concrete defects and their prevention and cure measures.
