Foundation pit enclosure system with umbrella-shaped ring beam support and construction method
The invention discloses a foundation pit enclosure system with an umbrella-shaped ring beam support and a construction method. The system comprises a foundation pit, a plurality of vertical enclosure piles are arranged on the periphery of the foundation pit, a ring beam is arranged in the foundation pit, a plurality of stand column piles are annularly and vertically arranged at the bottom of the ring beam, and the bottom ends of the stand column piles are fixed in the foundation pit; a plurality of umbrella-shaped supporting components are arranged in the circumferential direction of the ring beam, and the other ends of the umbrella-shaped supporting components are fixedly installed on the fender posts to form overall supporting of the foundation pit. A plurality of force transmission belts are fixedly arranged on the side wall of the foundation pit, and the force transmission belts are connected with the corresponding cast-in-place slabs; the method comprises the steps of fender post construction, supporting system construction, force transmission belt and floor slab construction, supporting system dismantling and foundation pit backfilling. According to the structure, the foundation pit is integrally reinforced, supporting points are reasonably arranged, the overall stability is good, the supporting structure occupies a small space of the foundation pit, mechanical excavation operation is convenient, the construction period is convenient to shorten, the overall structure is simple and compact, and the method is short in construction period, small in construction difficulty and good in overall construction economical efficiency.
本发明公开了一种具有伞型环梁支撑的基坑围护体系及施工方法，该体系包括基坑，在基坑四周设置若干根竖向围护桩，在基坑内设有环梁，在环梁底部呈环状竖向设有若干立柱桩，立柱桩底端固定在基坑内；在环梁周向设有多个伞形支撑构件，伞形支撑构件另一端固定安装在围护桩上、形成对基坑的整体支撑；在基坑侧壁上固定设有多块传力带,传力带与对应现浇板连接；该方法包括围护桩施工、支撑体系施工、传力带及楼板施工、支撑体系拆除和基坑回填。该结构对基坑进行整体加固，支撑点布置合理，整体稳定好，支撑结构占用基坑空间较小，便于机械化挖掘作业，便于缩短施工周期，整体结构简单紧凑，该方法施工周期短，施工难度小，整体施工的经济性较好。
