Foundation pit supporting structure adopting steel sheet pile reverse construction method
The invention discloses a foundation pit supporting structure adopting a steel sheet pile reverse construction method. The foundation pit supporting structure comprises a bottom plate, a plurality of shells arranged at equal intervals are fixedly connected to the upper surface of the bottom plate, springs are fixedly connected to the bottom walls of the inner sides of the shells, supporting plates are fixedly connected to the top ends of the springs, the outer side walls of the supporting plates are slidably connected to the inner side walls of the shells, top plates are fixedly connected to the top ends of the supporting plates, sliding plates are slidably connected to the rear surfaces of the supporting plates, a plurality of forward and reverse rotation motors arranged at equal intervals are installed on the upper surface of the bottom plate, threaded rods are fixedly connected to output shafts of the forward and reverse rotation motors, threaded sleeves are in threaded connection with the outer side walls of the threaded rods, first connecting rods are hinged to the upper surfaces of the threaded sleeves, and the first connecting rods are hinged to the rear surfaces of the sliding plates. The forward and reverse rotation motors drive the threaded rods to rotate through the output shafts of the forward and reverse rotation motors, so that the threaded sleeves move along the track of the outer side walls of the threaded rods, the sliding plates are pushed to move up and down through the first connecting rods, supporting points of foundation pit supporting are freely adjusted, and the supporting effect is improved.
本发明公开了一种钢板桩逆作法基坑支护结构，包括底板，所述底板的上表面固接有若干个等距排列的壳体，壳体的内侧底壁固接有弹簧，弹簧的顶端固接有支撑板，支撑板的外侧壁滑动连接于壳体的内侧壁，支撑板的顶端固接有顶板，支撑板的后表面滑动连接有滑动板，底板的上表面安装有若干个等距排列的正反转电机，正反转电机的输出轴固接有螺纹杆，螺纹杆的外侧壁螺纹连接有螺纹套管，螺纹套管的上表面铰接有第一连接杆，第一连接杆铰接于滑动板的后表面。正反转电机通过其输出轴带动螺纹杆转动，从而使螺纹套管沿着螺纹杆外侧壁的轨迹进行移动，进而通过第一连接杆推动滑动板上下移动，从而对基坑支护的支撑点进行自由调整，提高了支撑效果。
