Method for dismantling existing canopy of elevated operation subway station
The invention discloses a method for dismantling an existing canopy of an elevated operation subway station. The method comprises the following steps of S1, building extension platforms on two sides of an outer edge rail-mounted area of an elevated operation subway; S2, building a portal truss unit group outside the extension platforms, hoisting the portal truss unit group onto the extension platforms, and moving the portal truss unit group to a position above the existing canopy along the extension platforms; S3, splitting the existing canopy into canopy unit blocks; and S4, using the portal truss unit group for sequentially hoisting the canopy unit blocks, and after the portal truss unit group travels to the ends of the extension platforms, integrally hoisting the portal truss unit group to the ground to be disassembled. According to the method, under the condition that normal operation of the subway station is guaranteed, the existing canopy of the station can be rapidly dismantled, the construction period can be shortened, and the construction cost is reduced.
本发明公开了一种高架运营地铁车站既有雨棚的拆除方法，其中，所述方法包括：S1，在高架运营地铁外沿轨行区两侧搭建延伸平台；S2，在所述延伸平台外搭建门式桁车单元组，将所述门式桁车单元组吊至所述延伸平台上，并沿所述延伸平台移动至既有雨棚上方的位置；S3，将所述既有雨棚拆分成各雨棚单元块；S4，利用所述门式桁车单元组依次吊装所述各雨棚单元块，走行至所述延伸平台的端部后，将所述门式桁车单元组整体吊装至地面后解体。本发明可在保证地铁车站正常运营的情况下实现对车站既有雨棚的快速拆除，并能缩短施工周期，降低施工成本。
