摘要
目前,设计单位往往采用设置施工后浇带的方法来解决建筑物因温度变化、混凝土收缩导致的混凝土裂缝问题,这是一种防止混凝土开裂的很有效的手段,但是工程实践表明,施工后浇带的存在会给现场施工造成很多困难,同时也存在一些质量隐患。跳仓法施工工艺是一种取代施工后浇带,解决超大、超长、超宽混凝土结构收缩、温度裂缝问题的有效手段,并且便于实施,已经越来越广泛地被用于工程实践。
At present,design units often adopt the method of setting up pouring belts after construction to solve the problem of concrete cracks caused by temperature changes and concrete shrinkage.This is a very effective means to prevent concrete cracking.However,engineering practice shows that pouring after construction The existence of the belt will cause many difficulties for on-site construction,and there are also some hidden quality problems.The construction technology of skipping warehouse method is an effective means to replace the post-construction pouring belt and solve the problems of shrinkage and temperature cracks in super-large,super-long and super-wide concrete structures,and is easy to implement.It has been increasingly used in engineering practice.
