Steel-concrete combined inner support for deep foundation pit and dismantling construction method of steel-concrete combined inner support
The invention relates to the field of foundation pit supporting, in particular to a deep foundation pit steel-concrete combined inner support and a dismantling construction method thereof.The deep foundation pit steel-concrete combined inner support comprises a retaining wall arranged along the inner side wall of a foundation pit, surrounding purlins are fixedly installed on the inner wall of the retaining wall in the circumferential direction, supporting columns are installed between the two adjacent sides of the surrounding purlins, and supporting pipes are arranged between the two opposite inner side walls of the surrounding purlins; steel brackets are arranged at the two ends of the supporting pipe and fixedly installed on the inner wall of the enclosing purlin, a fixed connector is connected to one end of the supporting pipe through a flange, a sliding column is arranged at the other end of the supporting pipe in a sliding and penetrating mode, a pressing plate is fixedly installed at the end, away from the fixed connector, of the sliding column, and the sliding column is provided with a threaded rod and a bayonet allowing the threaded rod to penetrate through. A limiting block is fixedly installed at one end of the screw, the screw is sleeved with a first limiting ring in a threaded mode, a clamping block is installed on the screw in a sliding mode, the clamping block is located between the first limiting ring and the limiting block, and the clamping block is connected to the bayonet in a clamped mode. The dismounting method has the effect of reducing the dismounting difficulty of the steel-concrete combined inner support of the deep foundation pit.
本申请涉及基坑支护的领域，尤其是涉及一种深基坑钢混组合内支撑及其拆除施工方法，包括沿基坑内侧壁设置的挡土墙，挡土墙的内壁沿周向固定安装有围檩，围檩的相邻两侧之间安装有支撑柱，围檩的相对两内侧壁之间设置有支撑管，支撑管的两端均设置有钢托架，钢托架固定安装于围檩的内壁，支撑管的一端法兰连接有固定接头，支撑管的另一端滑移穿设有滑移柱，滑移柱远离固定接头的一端固定安装有压板，滑移柱设置有螺杆，滑移柱开设有供螺杆穿设的卡口，螺杆的一端固定安装有限位块，螺杆螺纹套设有第一限位环，螺杆滑移安装有卡块，卡块位于第一限位环和限位块之间，卡块卡接于卡口。本申请具有减小深基坑钢混组合内支撑的拆除难度的效果。
