Subway station permanent and temporary combined open excavation sequential construction structure and construction method
The invention discloses a subway station permanent and temporary combined open excavation sequential construction structure and a construction method. The subway station permanent and temporary combined open excavation sequential construction structure comprises an enclosure structure and a main body structure, wherein the main body structure comprises a prefabricated top plate, a prefabricated middle plate and a stand column; the prefabricated top plate is located above the prefabricated middle plate; the stand column is vertically arranged in the middle of the prefabricated top plate and theprefabricated middle plate; the enclosure structure comprises a first support, a second support and a section steel lattice column; the first support and the prefabricated top plate are connected ina supporting mode to form a permanent and temporary combined top plate structure; the second support and the prefabricated middle plate are connected in a supporting mode to form a permanent and temporary combined middle plate structure; and the stand column and the section steel lattice column are connected in a supporting mode to form a permanent and temporary combined stand column structure. According to the subway station permanent and temporary combined open excavation sequential construction structure, structural members such as reinforced concrete inner supports, temporary stand columnsand temporary connecting beams in a temporary structure do not need to be dismantled or chiseled away, materials and labor are saved, noise pollution and energy loss are avoided, meanwhile, the construction period is shortened, the working efficiency is improved, the safety and stability of a foundation pit are guaranteed, the structure stress is reliable, and the structure durability is not reduced.
本发明公开了一种地铁车站永临结合明挖顺筑结构及施工方法，包括围护结构和主体结构；主体结构包括预制顶板、预制中板和立柱，预制顶板位于预制中板的上方，立柱竖向设置在预制顶板和预制中板的中部；围护结构包括第一道支撑、第二道支撑和型钢格构柱，第一道支撑和预制顶板支撑连接形成永临结合顶板结构，第二道支撑和预制中板支撑连接形成永临结合中板结构，立柱和型钢格构柱支撑连接形成永临结合立柱结构。该结构不需要拆除或凿除临时结构中的钢筋混凝土内支撑、临时立柱及临时连系梁等结构构件，节省材料和人工，避免了噪音污染和能源损耗，同时节约了工期，提高了工作效率，并且保证了基坑安全稳定，结构受力可靠、结构耐久性不降低。
