Highway-railway combined construction underground station structure and construction method thereof
The invention relates to a highway-railway combined construction underground station structure. The highway-railway combined construction underground station structure comprises a plurality of shieldsegments, wherein concrete linings are arranged in the shield segments; underground station spaces are formed in the concrete linings; top plates, underground second-layer plates, underground third-layer plates and underground fourth-layer plates are arranged in the concrete linings; the underground station spaces are divided into highway pipeline layers, municipal highway layers, subway station hall layers, subway station platform layers and comprehensive bottom layers, and brackets are arranged on the bottom sides of the top plates, the underground second-layer plates and the underground third-layer plates of the concrete linings; the municipal highway layers comprise highways and evacuation passages, first partition walls are arranged between the evacuation passages and the highways, and a plurality of escape doors are formed in the first partition walls; the subway station platform layers comprise prefabricated platforms and subway tracks, platform cast-in-place layers are arrangedon the prefabricated platforms, and prefabricated air ducts are formed in the bottoms of the underground third-layer plates; and prefabricated box-shaped frames are arranged in the comprehensive bottom layers. The invention further relates to a construction method of the highway-railway combined construction underground station structure. The construction method comprises seven steps. According to the highway-railway combined construction underground station structure and the construction method thereof, the problem of underground excavation construction of underground stations under complexenvironmental conditions can be solved.
本发明涉及一种公铁合建地下车站结构，包括若干节盾构管片，盾构管片内设砼内衬，砼内衬内形成地下车站空间，砼内衬内设顶板、地下二层板、地下三层板和地下四层板，将地下车站空间分为公路管线层、市政公路层、地铁站厅层、地铁站台层和综合底层，砼内衬在顶板、地下二层板和地下三层板的底侧均制有牛腿；市政公路层包括公路和疏散通道，疏散通道与公路间设第一隔墙，第一隔墙开设若干逃生门；地铁站台层包括预制站台和地铁轨道，预制站台上设站台现浇层，地下三层板的底部设预制风道；综合底层内设预制箱型框架；还涉及该公铁合建地下车站结构的施工方法，包括七个步骤。本发明可解决复杂环境条件下暗挖施工地下车站的难题。
