Recyclable supporting mechanism for foundation pit support
The invention belongs to the technical field of building or reinforcement of excavation in fixed buildings, and particularly relates to a recoverable supporting mechanism for foundation pit bracing. The connecting columns are arranged at the soil drilling cones at the lower ends of the steel pipe piles, and when the steel pipe piles are dismounted outwards, the connecting columns are driven by soil to be disengaged from the steel pipe piles, so that medium sand filled in the steel pipe piles flows out according to the gravity of the medium sand, and the technical problem of clearing away the filling sand in the pipes when the supporting structure is dismounted is solved. The method has the advantages that when the steel pipe pile is dismounted outwards, the connecting column unit is separated from the lower end of the steel pipe pile, so that medium sand in the steel pipe pile flows out according to the gravity of the medium sand; fourthly, by arranging a clamping block unit and a locking pin unit, the connecting column and the bottom end of the steel pipe pile can be directly locked by installing the inserting column; and fifthly, by arranging a reset plate unit, when the steel pipe pile is dismantled, the connecting column can be smoothly disengaged, and the soil drilling cone is automatically left in foundation pit soil.
本发明属于固定建筑物中挖方的修砌或加固技术领域，尤其涉及一种用于基坑围护的可回收支护机构。本发明在钢管桩下端钻土锥处设置了连接柱，当向外拆除钢管桩时，连接柱在泥土的带动下与钢管桩脱离卡合状态，从而钢管桩内部填充的中砂根据自身重力而流出，解决了支护结构拆除时清除管中填充砂的技术问题。本发明的优点在于：向外拆除所述钢管桩时，连接柱单元与所述钢管桩下端脱离卡合，使得钢管桩内的中砂根据自身重力而流出；第四、通过设置卡接块单元与锁定销单元，使得安装插入柱的行为可以直接锁定连接柱与钢管桩底端；第五、通过设置复位板单元，使得拆除钢管桩时，连接柱能够顺利脱离，使得钻土锥自动留在基坑土内。
