施工缝的相关知识-----外文翻译.doc

Construction joint refers to the concrete pouring process, design or construction needs due to pouring the earlier section, after the pouring of concrete joints formed between. Construction joint is not a real problem of "joint", it is only after the pouring of concrete for more than the initial setting time, and the first one between the pouring of concrete joint surface, called the combination of the surface of the construction joint.
Concrete pouring for the formation of the joint surface successively prone to various hazards and quality problems, therefore, different structural works on the construction joint of the address have to be doubly cautious.

Construction joint is not a real problem of "joint", it is only after the pouring of concrete for more than the initial setting time, and the first one between the pouring of concrete joint surface, called the

施工缝指的是在混凝土浇筑过程中，因设计要求或施工需要分段浇筑而在先、后浇筑的混凝土之间所形成的接缝。 施工缝并不是一种真实存在的“缝”，它只是因后浇筑混凝土超过初凝时间，而与先浇筑的混凝土之间存在一个结合面，该结合面就称之为施工缝。
　　因混凝土先后浇注形成的结合面容易出现各种隐患及质量问题，因此，不同的结构工程对施工缝的处理都需要慎之又慎。
