Foundation pit beam string structure and concrete supporting structure
The invention relates to a foundation pit beam string structure and concrete supporting structure. The foundation pit beam string structure and concrete supporting structure comprises enclosing purlins, supporting structures, sealing plates, a beam string structure and a prestress applying structure. The enclosing purlins are arranged around the foundation pit; the supporting structures and the sealing plates are arranged at four corners in the enclosing purlins and are rigidly connected with the enclosing purlins, and outer main supports are arranged on the outer sides of the supporting structures; the prestress applying structure is connected with the supporting structure and the beam string structure; the beam string structures are arranged on the four sides in the enclosing purlins and connected with the prestress applying structure. The prestress applying structure is arranged at the connecting position of the concrete main support and the beam string structure, deformation of a key point at the position can be actively controlled, foundation pit deformation of the connecting position of the concrete main support and the beam string structure and the range of the beam string structure is effectively controlled, and the safety of the foundation pit is more effectively guaranteed.
本发明涉及一种基坑张弦梁与混凝土支撑结构，包括围檩、支撑结构、封板、张弦梁、以及预应力施加结构；围檩设置在基坑四周；支撑结构与封板设置于围檩内四角并与围檩刚性连接，其中支撑结构外侧设有外主撑；预应力施加结构连接支撑结构与张弦梁；张弦梁设置于围檩内四边并与预应力施加结构相连接。本发明中混凝土主撑与张弦梁连接处设置预应力施加结构，能够主动控制此位置关键点的变形，有效地控制混凝土支撑与张弦梁连接位置和张弦梁范围的基坑变形，更加有效地保证基坑的安全。
