Shallow foundation pit excavation rigid frame supporting structure and construction method
The invention provides a shallow foundation pit excavation rigid frame supporting structure and a construction method. The shallow foundation pit excavation rigid frame supporting structure comprises a shallow foundation pit slope and a rigid frame supporting structure body; net sprayed concrete is arranged on the inner side of the shallow foundation pit slope; net sprayed concrete vertical steel bars and net sprayed concrete horizontal steel bars are arranged in the net sprayed concrete; the rigid frame supporting structure body is arranged on the outer side of the net sprayed concrete; one side of the rigid frame supporting structure body is attached to the inner side of the shallow foundation pit slope, and the bottom side of the rigid frame supporting structure body is attached to the bottom of a shallow foundation pit; the net sprayed concrete horizontal steel bars are reliably connected with the rigid frame supporting structure body; and a constraint structure is arranged at the bottom end of the bevel edge, away from the net sprayed concrete, of the rigid frame supporting structure body. According to the shallow foundation pit excavation rigid frame supporting structure which is simple in structure, reasonable in design and convenient and fast to construct, surrounding buildings (structures) and pipelines can be protected in the foundation pit excavation process, construction is convenient, and therefore the construction period is shortened, and the foundation pit construction cost is reduced.
本发明提供了一种浅基坑开挖刚架支撑结构及施工方法，包括浅基坑边坡、刚架支撑结构；所述浅基坑边坡内侧设置有网喷混凝土；所述网喷混凝土内设置有网喷混凝土竖向钢筋、网喷混凝土水平向钢筋；所述网喷混凝土外侧设置所述刚架支撑结构，所述刚架支撑结构的一边贴合所述浅基坑边坡内侧，底边贴合浅基坑底部；所述网喷混凝土水平向钢筋与所述刚架支撑结构可靠连接；所述刚架支撑结构远离所述网喷混凝土的斜边底端设置有约束结构。本发明通过一种结构简单、设计合理、施工便捷的浅基坑刚架支撑结构，在基坑开挖过程中可对周边建(构)筑物、管线进行保护，且施工便利，从而节约工期、降低基坑施工造价。
