Narrow foundation pit overwater steel support mounting platform and construction method thereof
The invention discloses a narrow foundation pit overwater steel support mounting platform and a construction method thereof. The installation platform is formed by assembling module boxes which are produced in a standardized mode. According to the construction method, the assembled steel support mounting platform is hung and placed in a narrow foundation pit, the scabbling equipment, the steel supports and the winch are stored on the mounting platform, the working procedures of scabbling the wall surfaces of the underground diaphragm walls and erecting the steel supports are sequentially completed from top to bottom along with descending of the water level in the pit, and finally the mounting platform is disassembled, and the steel supports are hung out of the narrow foundation pit and reused. The narrow foundation pit overwater steel support mounting platform is simple in structure, all parts are machined in a standardized mode through a factory, mounting and dismounting are convenient, and the problems that cross operation space of narrow spaces such as small compartments is limited, and operation is difficult are solved. And compared with a ladder cage and operation platform erecting mode, the platform and the underground diaphragm wall do not need to be fixed and lengthened, steel is saved, the construction period is remarkably shortened, and the method has extremely high application and popularization value.
本发明公开了一种狭小基坑水上钢支撑安装平台及其施工方法。该安装平台由标准化生产的模块箱组拼而成。该施工方法中，组拼完成的钢支撑安装平台吊放入狭小基坑中，凿毛设备、钢支撑及卷扬机存放于安装平台上，随坑内水位下降自上至下依次完成各层地连墙墙面凿毛及钢支撑架设工序，最后拆除安装平台，自狭小基坑中吊出并重复利用。本发明的狭小基坑水上钢支撑安装平台结构简单，各部件由工厂标准化加工，安拆方便，解决了小隔舱等狭小空间交叉作业空间受限、作业困难问题。相对于架设梯笼和作业平台方式，无需将平台与地连墙固定并接长，节省钢材使用，显著缩短建造工期，具有极高的推广使用价值。
