The invention relates to the field of tunnel construction platforms, in particular to a starting steel platform for a pipe jacking method overlapped tunnel and a construction method of the starting steel platform. According to the technical scheme, the device is characterized by comprising a raft located at the bottom of a starting well; the at least four rail supporting columns are vertically arranged on a raft plate, and the multiple rail supporting columns are evenly distributed on the periphery of the raft plate; the lifting platform is arranged on the multiple track supporting columns in a sliding mode; the lifting mechanism is connected with the lifting platform and used for driving the lifting platform to ascend and descend; and the locking mechanism is arranged on the lifting platform and used for being locked to the rail supporting columns so that the lifting platform can horizontally stay at the multiple height positions of the rail supporting columns, the function of meeting the rapid starting construction requirement of the multi-section overlapped tunnel can be achieved, and meanwhile the overall construction benefit can be improved.

    本申请涉及隧道施工平台的领域,尤其是涉及一种用于顶管法叠交隧道的始发钢平台及其施工方法。其技术方案的要点是:包括位于始发井底部的筏板;至少为四根轨道支柱,竖向设置于筏板上,多根所述轨道支柱均匀排布于所述筏板的四周;升降平台,滑动设置于多根所述轨道支柱上;升降机构,与所述升降平台连接,用于驱使所述升降平台升降位移;以及锁止机构,设于所述升降平台,用于锁合至所述轨道支柱,以使所述升降平台水平停留至轨道支柱的多个高度位置处,本申请具有满足多段叠交隧道快速始发施工要求的功能,同时还可提升整体的施工效益。
