Fabricated vertical truss supporting system for deep foundation pit and construction method of fabricated vertical truss supporting system
The invention discloses a deep foundation pit fabricated vertical truss supporting system and a construction method thereof. According to the system, front-row H-shaped steel stand column piles and rear-row H-shaped steel stand column piles corresponding to the front-row H-shaped steel stand column piles are arranged in a foundation pit; the front-row H-shaped steel stand column piles and the rear-row H-shaped steel stand column piles are connected through supporting structures. The front-row H-shaped steel stand column piles and the rear-row H-shaped steel stand column piles are connected through the horizontal pressing rods and the X-shaped supporting rods, so that the front-row H-shaped steel stand column piles, the rear-row H-shaped steel stand column piles, the horizontal pressing rods and the X-shaped supporting rods jointly form the vertical truss with high rigidity, and deformation of a foundation pit is resisted through the rigidity of the vertical truss. The device has the characteristics of safety, reliability, high integral rigidity, high deformation control capability, capability of effectively retaining soil and water, complete assembly, high construction efficiency, reusability, low manufacturing cost, capability of greatly improving the excavation efficiency of the foundation pit without arranging a support in the foundation pit, and the like.
本发明公开一种深基坑装配式竖向桁架支护系统及其施工方法。所述系统包括：在所述的基坑内设置有前排H型钢立柱桩以及对应前排H型钢立柱桩设置的后排H型钢立柱桩；所述的前排H型钢立柱桩与后排H型钢立柱桩间通过支撑结构相连。本发明通过用水平压杆和X形撑杆将前排H型钢立柱桩与后排H型钢立柱桩相连，使“前排H型钢立柱桩、后排H型钢立柱桩、水平压杆、X形撑杆”共同组成具有很大刚度的竖向桁架，用竖向桁架的刚度抵抗基坑变形。具有安全可靠，整体刚度大，变形控制能力强，可有效挡土和止水，完全装配化、施工效率高、可重复利用、造价低、基坑内不必设置支撑可大大提高基坑开挖效率等特点。
