Segmental Bridge Zhengzhou Freeway Construction

Zhengzhou Freeway Project pictures from Gernot Komar on the freeway construction in China. The Precast Segmental units are shown in the casting yard and being placed in on a Pier section in Balanced Cantilever method. The Pier section shows double sections for freeway lanes and the single section units are for ramp construction. Gernot’s company SETI(SUNENGTECH.com). For more information contact us at PETutors . Freeways consist of a 100 km bridge and 100 km of ramps both are precast prestressed segmental construction. These structure types are cost effective is span ranges from 200 to 500 feet making these types of bridges very useful in locations of environmentally sensitive areas minimizing the ground disturbance and utilizing top down construction method.
