闸墩混凝土施工裂缝预防与控制

Prevention and Control of Cracks in Pier Concrete Construction

受水泥水化热、气温、闸墩厚度、混凝土收缩、施工等多种因素影响,闸墩混凝土结构在施工和使用中不可避免地会出现裂缝问题。这在一定程度上影响了闸墩的使用寿命,给整个工程带来安全隐患。基于此,对闸墩混凝土施工裂缝预防与控制问题进行研究,目的在于改善闸墩混凝土施工条件与工艺,预防混凝土裂缝的出现,提高工程施工质量。

Influenced by many factors,such as cement hydration heat,air temperature,pier thickness,concrete shrinkage,construction and other factors,cracks will inevitably appear in the construction and use of pier concrete structure.This affects the service life of the pier to a certain extent,and brings hidden danger to the whole project.Based on this,this paper studies the prevention and control of pier concrete construction cracks>the purpose is to improve the pier concrete construction conditions and technology,prevent the occurrence of concrete cracks,and improve the construction quality.
