Embodiment 1

[0030] The present invention relates to a construction method for demolishing buildings on an existing track operation section, comprising the following steps: erecting a safety isolation protection structure in the track section of the existing track to separate the track section and the operation area, so as to ensure that the running of the train and the demolition construction will not be interrupted. Influence each other, and implement the requirements of safe operation and closed isolation of the track.

[0031] The safety isolation and protection structures are located on both sides and above the track area or only on both sides of the track area. When the building to be demolished crosses the track area, the safety isolation and protection structures on both sides and above the track area are used to protect the track area. When the buildings to be demolished are located on both sides of the track area and do not cross the track area, the safety isolation protection str...

Embodiment 2

[0037] The invention relates to a construction method for demolishing a building in an existing track operation section. The building to be demolished is a station, and the station includes a station main structure located on one side of the track area, a platform structure located on the track area, and a station located in the track area. The other side of the bridge is attached to the stairs, and the platform structure includes platform plates on both sides of the track area and a spanning structure above the track area.

[0038] The removal sequence is:

[0039] Step a, use the skylight points where the track is out of service at night to complete the erection of the safety isolation protection structure, and then erect the lighting glass protection net before removing the attached stairs of the overpass to protect the lighting glass on the platform wall, and finally use the shearing equipment. The auxiliary stairs of the overpass are removed, and the shearing equipment ad...

Abstract

The invention discloses a construction method for demolishing a building on an existing track operating section, comprising the following steps: erecting a safety isolation protection structure in the track running section of the existing track to separate the track running section and the working section; dismantling the building to be demolished Carry out safety risk zoning, high-risk areas are dismantled manually, medium-risk areas are dismantled with cutting or drilling equipment and cranes, and low-risk areas are dismantled with shearing equipment. Compared with the prior art, the present invention has the following advantages and beneficial effects: a safety isolation protection structure is set up in the track area of ​​an existing subway station to separate the subway operation area and the station demolition operation area, so as to avoid the mutual influence of the two areas; The ordinary formwork system provides safety isolation and protection for the subway operation area, which is convenient for installation and demolition; divides the safety risk of the buildings to be demolished, and formulates demolition plans respectively, which not only ensures the construction efficiency, but also ensures the construction safety; proposes shearing, cutting and drilling equipment Combined with the composite construction method of the crane, the static demolition of the subway station is realized, and the construction efficiency is guaranteed at the same time.

Description

technical field [0001] The invention relates to a construction method for building dismantling, in particular to a construction method for dismantling buildings in an existing track operation section. Background technique [0002] Due to the rapid development of the city and the continuous increase of the urban population, more and more buildings in the existing rail operation area can no longer meet the current demand, and it is necessary to construct new buildings or demolish old buildings in the existing rail operation area. objects, which is especially common at stations where multiple lines meet. [0003] When construction is carried out on the existing track operation section, since there is no block or barrier between the construction work surface and the track running area of ​​the track, building materials and mechanical equipment are likely to fall into the track running area during construction, resulting in potential On the other hand, in order to avoid the inte...
