静态破碎施工在既有建筑结构拆除中的应用

Application of Static Crushing Construction to Demolishing of Existing Building Structure

上海浦东国际机场T1航站楼流程改造工程,需要拆除原有连廊层的钢筋混凝土梁和楼板结构,但要在不影响航站楼正常使用的前提下完成。通过对静态破碎方法的优化设计和实施,有效地控制了拆除过程中的粉尘、噪声等的影响,监测数据表明整个结构的变形也在设计允许范围之内。

The process reconstruction of Shanghai Pudong International Airport Terminal T1 needs to demolish the existing reinforced concrete beam and floor structure of the connecting corridor floor, without affecting the normal airport operation. Thanks to the optimal design and implementation of the static crushing method, the influences of dust, noise and so on in process of demolition have been effectively controlled. The monitoring data show that the deformation of the whole structure is within the scope of design allowance.
