Bin cylinder type secant pile underground lattice wall foundation pit supporting structure
The invention discloses a silo-type secant pile underground lattice wall foundation pit supporting structure. Transverse secant piles are arranged between front-row longitudinal secant piles and rear-row longitudinal secant piles. Front-row pile top lattice deep beams are arranged at the tops of the front-row longitudinal secant piles; the tops of the rear-row longitudinal secant piles are provided with rear-row pile top lattice deep beams. And transverse pile top lattice deep beams are arranged at the tops of the transverse secant piles. The transverse pile top lattice deep beams, the front-row pile top lattice deep beams and the rear-row pile top lattice deep beams form a plane rigid frame structure; the waist beam is not arranged or arranged in front of the front row of longitudinal secant piles, and the inter-pile short anchor rods are correspondingly arranged behind the front row of longitudinal secant piles provided with the waist beam. The pile top lattice deep beam plane rigid frame structure, the pre-stressed anchor cables and the like and the longitudinal and transverse secant piles jointly form a silo type supporting space structure of the secant pile underground lattice wall. The construction cost is reduced, medium and hard strata are overcome, the occupied area of a mud pit and mud making equipment is reduced, construction is convenient and fast, turning is flexible, and the variable supporting requirement of the outer contour of the foundation pit is met according to the complex shape of the outer contour of the foundation pit.
本发明公开了一种仓筒型咬合桩地下格构墙基坑支护结构，前排纵向咬合桩与后排纵向咬合桩之间设有横向咬合桩；前排纵向咬合桩顶部设有前排桩顶格构深梁；后排纵向咬合桩顶部设有后排桩顶格构深梁；横向咬合桩的顶部设有横向桩顶格构深梁。横向桩顶格构深梁与前排桩顶格构深梁及后排桩顶格构深梁形成平面刚架结构；前排纵向咬合桩前不设或设有腰梁，设有腰梁的后方则相应设有桩间短锚杆。桩顶格构深梁平面刚架结构、预应力锚索等与纵横咬合桩共同形成咬合桩地下格构墙的仓筒型支护空间结构。降低工程造价，克服中、硬地层，减少泥浆池及制浆设备的占地面积，施工便捷，转折灵活，根据基坑外轮廓的复杂形状，满足基坑外轮廓多变的支护要求。
