Construction method for zero-distance vertical connection between newly-built subway station and existing subway station
The invention relates to the technical field of metro construction, and discloses a construction method for zero-distance vertical connection of a newly-built metro station and an existing metro station, which is characterized by comprising the following specific construction steps: S1, preparation before construction; s2, a fender post of the existing subway station top plate is broken and removed, punching is conducted on the fender post through a hand air drill, static expansion cracking is conducted on concrete through an expanding agent, and finally chiseling is conducted through an air pick; and S3, steel bars are planted on the top plate portions of the existing subway station and the newly-built subway station, formworks are installed on the top plate portions, the steel bars needing to be planted into the top plates are machined, the steel bars are arranged on the formworks, and the steel bars are fixed to the formworks through steel bar supports. The method not only ensures the safe operation of the existing subway line and the stability of the existing station structure, but also minimizes the influence of construction on station operation and passengers.
本发明涉及地铁施工技术领域，公开了一种新建地铁站与既有地铁站零距离垂直帮接的施工方法，施工的具体步骤如下：一种新建地铁站与既有地铁站零距离垂直帮接的施工方法，其特征在于，施工的具体步骤如下：S1，施工前准备；S2，既有地铁站顶板的围护桩破除，用手风钻在围护桩上进行打孔，通过膨胀剂将砼进行静态涨裂，最后用风镐进行凿除；S3，既有地铁站和新建地铁站顶板部位植筋，在顶板部位安装模板，将需要植入顶板的钢筋加工，在模板上布置钢筋，用钢筋支撑器将钢筋固定在模板上。该方法不仅确保了既有地铁线路的安全运行和既有车站结构的稳定性，而且最小化了施工对车站运营和乘客的影响。
