An Integrated Erection Method for Segmental Assembled Bridge in Urban District

Segmental assembled bridge erection has become the researching hotspot for constructors as demands of large interchange projects increase in recent years. In this paper, we mainly proposed an integrated bridge erection method and a newly designed multifunctional erection machine-TP120 that is capable of implementing super- and sub-structures construction simultaneously compares to traditional erection method, wherein, brief introductions of erector TP-120’s, bridge erection and retreat procedures, and a typical engineering practice are described. The implemental results show the proposed method is considerably competitive when facing strict environmental and technical requirements in urban area.
