Abstract: Fengshi River Bridge,the first highest bridge in Henan,is the largest concrete continuous rigid frame bridge in Henan express way.The superstructure of main span is the pre-stressed concrete continuous rigid frame,and the substructure is rectangular hollow thin wall pier,and the height of the highest pier is 107 m and with 2.2 m wide pile group foundation.The self-lifting platform trap door method was adopted to construct high pier;and the two-T synchronous suspending crane construction method with cantilever concreting was adopted to construct box girder.A field construction quality group was established,which was in charge of the entire process quality safety control and the technical guarantee,such key links as safety,material quality and so on;thus speeding up the construction progress and guaranteeing the project quality and the construction security,and which accumulated important project experience for the structural design and the construction quality control of continuous rigid frame bridges.
