Foundation pit supporting structure for upper-wall lower-pile construction
The invention relates to the technical field of building supporting structures. The foundation pit supporting structure comprises a steel reinforcement cage, locking opening pipes are symmetrically arranged on the two sides of the steel reinforcement cage and located in containing grooves, a plurality of horizontal steel bars are arranged in the steel reinforcement cage at equal intervals, and the two ends of each horizontal steel bar extend into the adjacent containing grooves correspondingly; reinforcing and locking devices attached to the outer wall of the fore shaft pipe are arranged at the two ends of each horizontal steel bar respectively, a connecting and cushioning device is arranged at the center in the steel reinforcement cage, limiting frames are symmetrically arranged on the two sides of the connecting and cushioning device and located on the top of the steel reinforcement cage, and grouting pipes are arranged in the limiting frames. Through work of the reinforcing locking device and the connecting cushioning device, the inner walls of the grooves in the two sides of the reinforcement cage can be further supported when the locking opening pipe is pulled out, concrete in the reinforcement cage can be further condensed when the grouting pipe is pulled out, and the enclosure strength and stability are greatly improved.
本发明涉及建筑支护结构技术领域。本发明公开了一种上墙下桩施工用基坑支护结构，包括钢筋笼，所述钢筋笼的两侧对称设有锁口管且位于放置槽内，所述钢筋笼内等距设有若干根水平钢筋，且水平钢筋的两端分别延伸至相邻的放置槽内，每一个所述水平钢筋的两端上分别设有贴合在锁口管外壁的加固锁定装置，所述钢筋笼内的中心处设有衔接缓震装置，所述衔接缓震装置的两侧对称设有限位架且位于钢筋笼的顶部，所述限位架内设有注浆管。本发明通过加固锁定装置和衔接缓震装置工作，在拔出锁口管时可以对钢筋笼两侧的开槽内壁进一步支撑并且在拔出注浆管时使钢筋笼内的混凝土进一步凝聚，使围护强度和稳固性大大提高。
