Construction method for implementing transfer between platform floor of existing subway station and platform floor of new subway station
The invention relates to a construction method for implementing transfer between a platform floor of the existing subway station and a platform floor of a new subway station. The construction method comprises the following steps of constructing the platform floor of the new subway station to a pedestrian path below a structural bottom plate of the existing subway station; reinforcing strata surrounding the pedestrian path; dividing a structural bottom plate longitudinal beam of a passageway which is arranged at a position of a table board of the existing subway station and is connected to the pedestrian path into a left portion and a right portion; respectively constructing the left portion and the right portion; correspondingly constructing surrounding rock of an excavation structure at a position of a structural bottom plate longitudinal beam on a side wall of a constructed pedestrian passage structure; breaking down a waterproof layer, a reinforcement cover, construction preliminary bracings and cross braces, a construction waterproof layer and assembling reinforcements on a structural bottom plate portion of a platform of the existing subway station; connecting a new structure and the existing structure by using embedded steel bars; pouring side walls and middle walls; constructing another structural bottom plate longitudinal beam to obtain a complete passageway structure; finishing construction of the passageway of the pedestrian path; and connecting the platform floor of the existing subway station to the platform floor of the new subway station. A construction process is safe, the practicability is high, and normal operation of the existing subway lines is not affected.
