Construction method for reconstructing and expanding existing elevated operation subway station building main body structure
The invention discloses a construction method for reconstructing and expanding an existing elevated operation subway station building main body structure. The construction method comprises the steps that S1, landscape platforms are built on the two sides of an existing subway platform; S2, a side platform section I is built on each landscape platform; S3, an extension supporting platform is built outside an existing elevated operation subway in the subway rail direction; S4, a portal truss unit group is built outside the extension platform, and the portal truss unit group is hoisted to the extension supporting platform; S5, new canopy assembling unit blocks are hoisted to the portal truss unit group, moved to preset positions and then assembled to form a newly-built canopy; S6, an existing canopy is split into canopy split unit blocks, and after the canopy split unit blocks are hoisted and slid to the extension supporting platform through the portal truss unit group, integral hoisting is performed for disassembling; and S7, construction of a side platform section II is completed, and the side platform section II and the side platform section I jointly form a side platform. According to the method, construction can be conducted under the condition that normal operation of a subway is guaranteed, and the method has the advantages of being small in construction difficulty, short in construction period, low in manufacturing cost and the like.
本发明公开了一种改扩建既有高架运营地铁车站建筑主体结构的施工方法，S1，在既有地铁平台的两侧建造景观平台；S2，在景观平台上建造侧式站台一段；S3，在既有高架运营地铁外沿地铁铁轨方向搭建延伸支撑平台；S4，在延伸平台外搭建门式桁车单元组，并吊至延伸支撑平台上；S5，将新的雨棚组装单元块吊至门式桁车单元组上，并移动至预定位置后组装形成新建雨棚；S6，将既有雨棚拆分成各雨棚拆分单元块，并通过门式桁车单元组吊装滑移至延伸支撑平台后，整体吊装解体；S7，完成侧式站台二段的施工，由侧式站台二段与侧式站台一段共同构成侧式站台。本发明可以在保证地铁正常运营的情况下进行施工，具有施工难度小，施工周期短，造价低等优点。
