Assembly type detachable waist beam supporting structure and using method thereof
The invention provides an assembly type detachable waist beam supporting structure and a using method thereof.The assembly type detachable waist beam supporting structure comprises a main supporting block of a circular structure composed of a plurality of steel pipes and a main supporting block of a circular structure composed of a plurality of steel pipes in an end-to-end hinged mode, every two adjacent steel pipes are connected through an adjusting device, and jacking devices are arranged on the outer rings of the steel pipes and can extend outwards; the ends of the jacking devices abut against a stress steel plate of the foundation pit support, and pressure sensors are arranged between the stress steel plate and the jacking devices. The main supporting block, the jacking device and the true circle adjusting device are basically connected through hinges or threaded sleeves, are convenient to install, dismantle and replace and can be repeatedly used. And the construction period for mounting and dismounting the inner supporting structure in the foundation pit needing enough hoisting space is effectively shortened. The method can be used for excavation of the foundation pit which is tight in construction period node, high in rainfall requirement, strict in foundation pit deformation control, provided with a support and needs enough hoisting space in an urban area, and has very high popularization value.
本发明提供一种装配式可拆卸腰梁支撑结构及其使用方法，包括多个钢管组成的圆形结构的主支撑块，多个钢管首尾铰接组成圆形结构的主支撑块，两个相邻的钢管间还通过调整装置连接，钢管外圈还设有顶紧装置，顶紧装置可向外延伸，多个顶紧装置端部地靠在基坑支护的受力钢板上，受力钢板与顶紧装置之间设有压力传感器。主支撑块、顶紧装置及真圆调整装置间基本都采用铰接或螺纹套筒连接，安装、拆除、更换方便，且可重复使用。有效的缩短了需要有足够吊装空间的基坑中内支撑结构安装拆除的工期。可以用于城区工期节点紧、降水要求高、基坑变形控制严的有支护需足够吊装空间的基坑开挖，具有很高的推广价值。
