Construction Technology for Segment Precasting and Installation of Pier Stud in Shanghai Yangtze River Bridge Project

The pier stud of non-navigable pier in deepwater area of Shanghai Yangtze River Bridge used the segment precasting and installation technology to replace the traditional cast-in-situ construction technology for pioneering domestic.This paper introduces construction technologies include segment precating for pier stud,vertical transportation on land,segment installation and cast-in-situ wet connector for concrete.Project results show that this method is safe,high quality and efficient to complete the entire project,open up a newway to the construction of pier studs in rivers or seas of our country.
