Self-adaptive assembly type steel structure foundation pit supporting system
The invention belongs to the technical field of foundation pit supporting, and particularly relates to a self-adaptive assembly type steel structure foundation pit supporting system. The device comprises a transverse supporting rod and single-limb telescopic rods, wherein the two single-limb telescopic rods are matched to form a V-shaped supporting component; transverse supporting rods and single-limb telescopic rods which are arranged on the same plane serve as one layer of supporting modules, and all the supporting modules are carried on the corresponding vertical stand columns. Each single-limb telescopic rod comprises a fixed section and a pushing section, and each pushing section comprises a pushing piece and a compensation piece which are axially arranged in sequence; an intermediate medium and a semiconductor chilling plate are arranged in the pushing piece; and the compensation piece is used for adjusting a tail power end gear of the reduction gear box so as to drive a head reinforcement end gear to drive the reinforcement rack to generate a jacking force compensation action along the axial direction of the single-limb telescopic rod. The supporting structure is integrally stressed, so that the integrity, stability and operation safety of a foundation pit soil body can be ensured, and the supporting structure has the advantages of being high in construction flexibility, low in turnover cost and low in noise.
本发明属于基坑支护技术领域，具体涉及一种自适应装配式钢结构基坑支护系统。本发明包括横向支撑杆以及单肢伸缩杆，两根单肢伸缩杆配合形成V型支撑构件；以同平面布置的横向支撑杆及单肢伸缩杆为一层支撑模块，各支撑模块均搭载于相应的竖向立柱上；各单肢伸缩杆均包括固定段以及顶推段，而顶推段则包括轴向依序布置的顶推件和补偿件；顶推件内置有中间介质和半导体制冷片；补偿件依托调节减速齿轮箱的尾部动力端齿轮，从而驱动首部增力端齿轮带动增力齿条产生沿单肢伸缩杆轴向的顶推力补偿动作。本发明利于支护结构整体受力，从而能确保基坑土体的整体性、稳定性和作业安全性，并同步具备施工灵活性高、周转成本低和噪音低的优点。
