Construction method for synchronously carrying out auxiliary construction and shield construction of subway station
The invention discloses a construction method for synchronously carrying out auxiliary construction and shield construction of a subway station, which is characterized in that horizontal and vertical displacement monitoring points of a gantry crane track beam are added after a gantry crane is installed and shield construction is carried out, so that the influence of auxiliary construction on the operation stability of the gantry crane can be monitored in real time; and the safety of shield construction is ensured. And then station accessory structure construction is carried out, station accessory construction is synchronously carried out in the shield construction process, an accessory construction stage is started in advance, 90% of station accessory structure construction can be completed after shield construction is completed, the construction progress is greatly accelerated, and the construction period is greatly shortened. Moreover, only a small part of the cast-in-situ bored piles are reserved after shield construction is completed, the post-cast strip construction can be completed in a whole area at a time conveniently, the small reserved cast-in-situ bored piles are cut off after the post-cast strip construction is completed, the cast-in-situ bored pile dismantling scheme is optimized, the construction progress of an accessory structure is accelerated, and the accessory construction period is shortened.
本发明公开了一种地铁车站附属施工与盾构施工同步进行的施工方法，其在安装好龙门吊进行盾构施工后增加了龙门吊轨道梁的水平和竖直位移监测点，以便于实时监测附属施工对龙门吊的运行稳定性所造成的影响，保证了盾构施工的安全性。然后进行车站附属结构施工，实现了在盾构施工过程中同步进行车站附属施工，提前进入附属施工阶段，在盾构施工完成后车站附属结构可以施工完成90％，大大加快了施工进度，极大地缩短了施工周期。并且，在盾构施工完成后仅预留少部分钻孔灌注桩，便于后浇带施工全区域一次性完成，待后浇带施工完成后再割除预留的少量钻孔灌注桩，优化了钻孔灌注桩拆除方案，加快了附属结构的施工进度，缩短了附属施工周期。
