PC construction method pile and inclined strut combined supporting structure system and construction method
The invention discloses a PC construction method pile and inclined strut combined supporting structure system and a construction method.The structure system comprises a PC construction method pile enclosure structure and a supporting structure, the enclosure structure comprises PC construction method piles, steel enclosing purlins and C25 fine aggregate concrete between the PC construction method piles and the steel enclosing purlins, and the method comprises the steps that (1) the range of the enclosure structure is determined according to the outer contour line of a basement and the width of a fat groove; a PC construction method pile is driven; (2) slope excavation is conducted on earthwork of a foundation pit core area; (3) constructing a foundation bottom plate and a bracket of the main body structure of the core area; (4) structures such as enclosing purlins, steel throwing supports and movable end heads are installed; (4) excavating residual earthwork in the sloping area; (5) constructing a sloping area bottom plate and an underground structure side wall; and 6) backfilling the fertilizer groove, and removing the steel support. The PC construction method pile and inclined throwing support combined supporting structure is clear in force transmission path, a main body structure is adopted as an inner supporting structure, the force transmission path is clear, and use of a large-area foundation pit horizontal temporary inner support and residual enclosure structures in the underground environment are avoided.
本申请公开了一种PC工法桩与斜撑组合支护结构体系和施工方法，结构体系包含PC工法桩围护结构和支撑结构，围护结构包含PC工法桩、钢围檩以及二者之间的C25细石混凝土，方法步骤：1)根据地下室外轮廓线和肥槽宽度确定围护结构范围，并打设PC工法桩；2)放坡开挖基坑核心区土方；3)施工核心区主体结构基础底板及牛腿；4)安装围檩、钢抛撑、活络端头等结构；4)开挖放坡区剩余土方；5)施工放坡区底板、地下结构侧墙；6)肥槽回填，拆除钢支撑。PC工法桩与斜抛撑组合支护结构传力路径明确，采用主体结构兼做内支撑结构，传力路径明确，避免了大面基坑水平临时内支撑的使用，及地下环境中残留围护结构。
