Large-diameter large-weight pipeline suspension protection foundation pit supporting structure and construction method
The invention discloses a large-diameter large-weight pipeline suspension protection foundation pit supporting structure and a construction method thereof. The large-diameter large-weight pipeline suspension protection foundation pit supporting structure comprises a foundation pit enclosure structure, a concrete transverse support, a pipeline and a suspension protection system; the suspension protection system comprises a concrete tie beam, a steel truss and a steel wire rope; the concrete tie beam is arranged in the direction of the pipeline, and the concrete tie beam is combined with the foundation pit enclosure structure and the concrete transverse support to form a concrete supporting truss system; the steel truss and the steel wire rope are arranged between the pipeline and the concrete transverse support to achieve suspension protection on the pipeline; and the steel truss comprises a plurality of vertical rods and a plurality of transverse rods, and the plurality of vertical rods and the plurality of transverse rods are connected through bolts or fixed in a welding mode. When construction is conducted, the concrete tie beam is arranged in the pipeline direction to form the concrete supporting truss system, and then suspension protection is conducted on the pipeline through the steel truss and the steel wire rope. According to the large-diameter large-weight pipeline suspension protection foundation pit supporting structure and the construction method thereof, the concrete supporting truss system is adopted, and therefore not only can the horizontal foundation pit supporting stress requirement be met, but also the large-weight pipeline suspension stress requirement can be met.
本发明公开了大直径大重量管道悬吊保护的基坑支撑构造及其施工方法，包括基坑围护结构、混凝土横撑、管道和悬吊保护体系；悬吊保护体系包括混凝土系梁、钢桁架和钢丝绳；混凝土系梁沿管道方向设置，且混凝土系梁与基坑围护结构和混凝土横撑结合形成混凝土支撑桁架体系；钢桁架和钢丝绳设置于管道与混凝土横撑之间对管道进行悬吊保护；钢桁架包括若干竖杆和若干横杆，若干竖杆和若干横杆之间通过螺栓连接或者焊接方式固定。施工时，先沿管道方向设置混凝土系梁形成混凝土支撑桁架体系；然后利用钢桁架和钢丝绳对管道进行悬吊保护。本发明采用混凝土支撑桁架体系，既满足水平向基坑支撑受力的要求，又能满足大重量管线悬吊受力的要求。
