高层建筑高度比较高,相应计算荷载种类较多,且荷载大,建筑基础承载抗倾覆及抗变形压力要求等级相应较高,高层建筑基础较多用箱形基础,加以考虑到人防工程、设备层的要求及地下停车场等因素,一般将箱形基础设计成带有地下室的箱形基础。由于带有地下室箱形基础具有一定使用功能,在基础施工过程中具有一定施工特点,产生了不同于其它基础施工方法,本文就地下室底板钢筋砼施工的工艺流程作一些探讨。
The height of high-rise buildings is relatively high, the types of calculated loads are relatively large, and the loads are large. The pressure rating requirements for anti-overturning and anti-deformation of building foundations are correspondingly high. The foundations of high-rise buildings are mostly based on box-shaped foundations, taking into account civil air defense projects and equipment layers. Requirements and underground parking lots and other factors, the box-shaped foundation is generally designed as a box-shaped foundation with a basement. Because the basement with the basement has a certain function, it has certain construction characteristics in the foundation construction process, and it produces different from other foundation construction methods. This article discusses the process flow of the reinforced concrete construction of the basement floor.
