Abstract

Research purposes:The main bridge of the Erqi Yangtze River Bridge in Wuhan is a composite girder cable－stayed bridge with three pylons and double cable planes． The Pylon Pier 5 is the side pylon pier among the three main pylons．The conventional scattered assembling method could not be used for the drilling platform and cofferdam for the deep water foundation because of the surrounding environment and the limitation of the construction schedule，so the special modular construction technology was studied and adopted．

Research conclusions:With this construction technology，the drilling platform and the cofferdam were divided into five large － scale modules，and the units manufactured in the factory were hauled to the pier site after being assembled integrally on the water in other places． On the construction site，the two modules used for supporting the cofferdam were hoisted by the large floating crane firstly．Then the steel casing was inserted，and the three modules of the drilling platform were hoisted to form a stable drilling platform． After these，the modules used for supporting the cofferdam were connected integrally and sunk to the design elevation． Finally，the cofferdam was built by inserting the steel casing along the inner support．This construction technology has features of the convenient installation，high construction security and reliable quality． Therefore，this construction technology can provide the reference to the similar works．

Key words
