Method for installing corridor with ultra-high double-tower steel structure

A method for installing a corridor with an ultra-high double-tower steel structure is applied after podium building construction and is characterized by comprising the steps that (a) an assembly platform and a jig frame are established for the corridor with the steel structure; (b) the corridor with the steel structure is assembled; (c) the assembly platform and the steel corridor slide; (d) a main body structure of the steel structure corridor is lifted as a whole synchronously through a hydraulic manner; (e) the main body structure of the steel structure corridor is finally positioned; and (f) lifting equipment, the steel corridor assembly platform and the jig frame are dismounted, so that the main body structure of the steel structure corridor is installed. The method for installing the corridor with the ultra-high double-tower steel structure disclosed by the invention has the advantages that safety risks in installation of an ultra-high tower steel corridor can be reduced greatly; and a construction period can be shortened for advanced use of a bottom podium building of an owner.
