Double-row pile enclosure structure and construction method thereof
The invention relates to the field of foundation pit support, in particular to a double-row pile support structure and a construction method thereof. The building envelope comprises front-row piles, front-row pile waist beams, front-row waist beam supporting brackets, anchor cables, anchor heads, rear-row piles, rear-row pile waist beams, front-row waist beam supporting brackets, anchor cables and anchor heads. The upper portions of the front-row piles and the upper portions of the rear-row piles are connected through the anchor cable structures, the anchor cable structures are fixed through the pile waist beams and the anchor heads, and the anchoring cantilever type enclosure structure is formed. The front-row pile waist beam is supported by a front-row waist beam supporting bracket; when the front-row piles are combined by the steel pipe piles and the steel sheet piles, the front-row steel pipe piles and the steel sheet piles are connected through rabbets; when the steel pipe piles are adopted in the front row, the steel pipe piles in the front row are connected through rabbets. Soil pressure is mainly borne by the front-row piles, and the rear-row piles mainly provide anchoring force for the front-row piles and bear certain soil pressure at the same time. The retaining structure is reliable in water stopping, environmentally friendly, recyclable, high in construction efficiency, low in manufacturing cost, short in construction period, small in influence on surrounding buildings (structures) and free of influence on later facility construction, and has good economic benefits and social benefits.
本发明涉及基坑围护领域，具体地说是一种双排桩围护结构及其施工方法。围护结构包含前排桩、前排桩腰梁、前排腰梁支撑牛腿、锚索、锚头、后排桩、后排桩腰梁、前排腰梁支撑牛腿、锚索、锚头。前排桩和后排桩上部由锚索结构连结，锚索结构由桩腰梁与锚头进行固定，形成一种锚拉式悬臂式围护结构。前排桩腰梁由前排腰梁支撑牛腿支撑；当前排桩采用钢管桩与钢板桩组合时，前排钢管桩与钢板桩之间由企口连接；当前排桩采用钢管桩时，前排钢管桩与钢管桩之间由企口连接。土压力主要由前排桩承受，后排桩主要为前排桩提供锚拉力，同时也承担一定土压力。本发明围护结构止水可靠、绿色环保可回收，施工效率高，造价节约，工期节省，对周边建(构)筑物影响小，不影响后期设施施工，具有较好的经济效益和社会效益。
