Foundation pit support system with firstly-supported and secondly-excavated all-steel structure combined with inclined piles
The invention relates to a foundation pit support system combining a first-supporting and second-digging all-steel structure with inclined piles, a portal frame type structure comprises a front-row HU support structure and a rear-row H-shaped steel, and an integral structure is formed through a coping ring beam and a connecting beam; the inclined pile can be H-shaped steel, a steel pipe, a hollow square pile, a hollow pipe pile, a solid square pile, a water stop groove square pile, a water stop groove circular pile and the like; the raking piles are embedded in the coping ring beam, and when the raking pile bodies are H-shaped steel or steel pipes, pre-embedded steel plates can be arranged on the coping ring beam to serve as welding connection measures; the vertical angle of the inclined pile can be adjusted within 15-50 degrees; the inclined pile can be pressed in through a special construction machine. The portal structure has the advantages that the portal structure is an all-steel structure (an HU enclosure structure and rear-row H-shaped steel), the inclined piles can be directly used and can be bought in the market, and the portal structure is convenient and fast to construct, low in manufacturing cost, energy-saving, environment-friendly, few in technical difficulty and convenient to popularize; meanwhile, the structure has multiple functions of reinforcement, skid resistance, soil retaining and water stopping.
本发明涉及一种先撑后挖全钢结构结合斜桩的基坑围护体系，所述的门架式结构包括前排HU围护结构+后排H型钢，通过压顶圈梁及连系梁形成整体结构；斜桩可以为：H型钢、钢管、空心方桩、空心管桩、实心方桩、止水槽方桩、止水槽圆桩等；斜桩埋入压顶圈梁内，当斜桩桩体为H型钢或钢管时，可在压顶圈梁设置预埋钢板作为焊接连接措施；斜桩竖向角度可以在15°～50°之内调整；斜桩可通过专用施工机械压入。本发明的优点是：门架结构为全钢结构(HU围护结构+后排H型钢)，斜桩为可直接使用桩体，可在市场上买到，施工方便、快捷，造价低，节能环保，技术难点少，推广便利；同时，结构本身具有加筋抗滑、挡土、止水多重作用。
