Construction method of combined anti-floating structure of open cut underground station in rock stratum
The invention discloses a construction method of a rock stratum open cut underground station combined type anti-floating structure. The construction method comprises the following steps that earth surface earthwork is excavated, and an earth surface intercepting ditch is constructed; excavating earth and stone at the upper part of the station, constructing a side slope spraying and mixing support, and arranging a side slope anchor rod; a slope bottom platform is constructed, and a platform intercepting ditch is constructed in the slope bottom platform; excavating earth and stone at the lower part of the station, and constructing a plate rib type anchor rod retaining wall; a foundation pit cushion layer is constructed, a waterproof layer is laid, and a station negative second layer structure is poured; anti-floating toes are arranged on a slope bottom platform to form a combined anti-floating structure; and a waterproof layer is laid, and station structure construction is completed. The advantages of high efficiency, safety and the like of rock stratum sloping method excavation are combined, the combined anti-floating structure is formed by the sloping platform and the anti-floating anchor rod retaining wall through permanent and temporary combination, the combined anti-floating structure has the advantages of being simple and convenient in construction procedure, high in safety, good in anti-floating effect, free of waste projects and the like, meanwhile, the construction period is shortened, the manufacturing cost is reduced, and the combined anti-floating structure has wide popularization prospects.
本发明公开了一种岩质地层明挖地下车站组合式抗浮结构的施工方法，包括以下步骤：开挖地表土方，施作地表截水沟；开挖车站上部土石方，施作边坡喷混支护，打设边坡锚杆；施作坡底平台，并在坡底平台上施作平台截水沟；开挖车站下部土石方，施作板肋式锚杆挡墙；施作基坑垫层，铺设防水层，浇筑车站负二层结构；在坡底平台施作抗浮脚趾，形成组合式抗浮结构；铺设防水层，完成车站结构施工。本发明结合岩质地层放坡法开挖的高效安全等优势、通过永临结合利用放坡平台与抗浮锚杆挡墙形成组合式抗浮结构，具备施工工序简便，安全性高、抗浮效果好、无废弃工程等特点，同时也节约了工期和造价，有着广泛的推广前景。
