The application of mobile frame type bridge assembling machine in PC box girder construction;

Construct PC box girders using mobile frame type bridge assembling machine;

According to the PC segment construction for Houhaiwan Approach Viaduct in Hongkong-Shenzhen Western Corridor (abbreviated as HSWC) ,the paper introduces and analyzes the steel construction design for PC segment according to British Standard and makes comparison with domestic design to the similar type of bridge construction for reference .

6-m simple-supported box girders of the Yangtze River Bridge at Tianxingzhou are cast in place with two sets of self-propelled forming frames made in Norway.

This paper gives an introduction to the applicable scope, main design parameters, design features, structural form, construction and erection requirements, structure constitution and so on of simple-supported box girder on passenger dedicated line in combination with the design situation of span-girder commonly adopted on Chinese passenger dedicated line.

Post-tensioned prefabricated concrete simple-supported box girders have been widely used in China including general railway bridges, passenger transportation railways and express railways; however, the pre-tensioned ones are mainly used in T-shaped girders.

From mode designing and making,installment and dismantlement of mode,reinforced concrete making and installment,concrete pouring and maintaining,and prestress tensile,it introduces the constructing skill of prestress simple support box beam,so as to offer reference for familiar projects.
