Problems solved by technology

However, at present, for the renovation of existing elevated operating subway stations, the available technical means are very limited, especially for the expansion and reconstruction of elevated multi-storey island stations in operation, how to ensure the normal operation of the subway station? To realize the rapid dismantling of the existing canopy, there are almost no technical means that can be used for reference

Embodiment 1

[0068] see Figure 2 to Figure 7 , an embodiment of the present invention is a method for dismantling an existing canopy of an elevated operating subway station, wherein the method includes:

[0069] S1, build extended platforms on both sides of the outer track area of ​​the elevated subway.

[0070] The construction method of the extended support platform 30 is as follows: first build the foundation of the extended support platform 30, then build the extended support platform 30 columns, beams and panels, and complete the construction of the extended support platforms 30 on both sides according to the above procedures.

[0071] When it is necessary to expand the side platform 50 outside the existing platform 121, a section 51 of the side platform can be built outside the existing platform 121, and the extension support platform 30 is connected with the section 51 of the side platform to form an integral support platform. In order to facilitate the hoisting of the gantry truc...

Embodiment 2

[0092] see figure 1 , the existing elevated operating subway station 10 includes the existing foundation column 11, the existing subway platform 12 and the existing canopy 13, wherein the existing subway platform 12 is set on the existing foundation column 11, and the existing canopy 13 is arched shape, and set up on the existing subway platform 12, the existing platform 121 is provided in the middle of the existing subway platform 12, and the two sides of the existing platform 121 are provided with subway rails 122. During operation, passengers enter and exit the existing platform 121 side of the subway.

[0093] In this embodiment, a subway station to be expanded is an elevated three-story island station, the main structure of the station is 21 meters high, 17.7 meters wide, and 120 meters long, the structure is a concrete frame structure, and the canopy is a curved steel frame The structure has a vertical distance of 6m and a total of 21 blocks. In order to meet the transf...

Abstract

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.

Description

technical field [0001] The invention relates to a method for dismantling an existing canopy of an elevated operating subway station, and belongs to the technical field of elevated operating subway transformation. Background technique [0002] The subway is a fast, large-capacity, and electric traction rail transit built in the city. The trains run on fully enclosed lines. The lines located in the central urban area are basically set in underground tunnels, and the lines outside the central urban area are generally set on viaducts or on the ground. The subway is an urban rail transit system that covers various underground and above-ground right-of-way proprietary, high-density, and high-capacity urban rail transit systems. [0003] With the continuous expansion of the subway traffic network, the passenger flow attracted by the subway is increasing day by day. There are more and more cases where a new subway line is designed and built next to the original elevated operating s...
