Large-span deep foundation pit steel concrete combined supporting structure
The invention provides a large-span deep foundation pit steel concrete combined supporting structure, and belongs to the technical field of foundation pit supporting. The large-span deep foundation pit steel concrete combined supporting structure comprises a plurality of prestressed beams and a plurality of supporting beams which are installed on the inner side of a structural beam, and each prestressed beam comprises a plurality of first connecting beams fixedly arranged on the inner side of the structural beam and first pull rods movably connected to the ends, away from the structural beam, of the first connecting beams through first inhaul cable connector joints. According to the large-span deep foundation pit steel concrete combined supporting structure, the problem that a vertical bearing component, namely a stand column or a stand column pile, must be arranged in a foundation pit of a conventional steel supporting system is solved; in addition, compared with the prior art, the stand column is not arranged, and therefore the cost can be reduced to a great extent; meanwhile, excavation of earthwork in the foundation pit is facilitated, and after prestress is applied through a tensioner, the self weight can be overcome, and self balance is achieved; and in addition, the prestressed beams and the supporting beams can be repeatedly used, and the beneficial effects of being safe, capable of saving energy, environment-friendly and the like are achieved.
本发明提供了一种大跨度深基坑钢砼组合支撑结构，属于基坑支护技术领域，包括安装在结构梁内侧的若干预应力梁以及若干支撑梁，所述预应力梁包括固定设置在所述结构梁内侧的若干第一联系梁以及通过第一拉索接头节点活动连接在所述第一联系梁远离所述结构梁一端的第一拉杆。本发明实施例解决了常规钢支撑系统必须在基坑内设置竖向承载构件即立柱或立柱桩的问题，另外相较于现有技术，不设立柱，可极大程度的降低成本，同时便于基坑内部土方的开挖，利用张紧器施加预应力后，可克服自重，实现自平衡，另外本发明实施例提供的预应力梁以及支撑梁可重复使用，具有安全、节能、环保等优点。
