摘要
冷轧取向硅钢工程中有很多的超长、大体积以及薄壁的混凝土结构,裂缝控制是土建施工的关键。在工程中,按照"抗放兼施、先放后抗、以抗为主"的原则,采用"无缝分块跳仓法",防止超长混凝土结构收缩产生裂缝;在隧道和池体的底板与墙板施工中,采用"整体浇筑"法,避免了墙板因约束应力而产生的裂缝。
In the Cold-rolled grain-oriented silicon steel project,there are many overlength,bulk mass,thin-walled concretes structures,how to control the crack is the key of civil engineering construction.In these projects,according to the principle of'release with resist,resist before release,resist is dominant ',the crack of the over-long structure and shrinkage can be prevented by the method of'seamless block skip bin '.In the construction of the bottom plate and wall of the tunnel and the pool,the cracks can be avoided by the method of'integral casting'.
