Abstract

The incremental launching construction method firstly is applied to the prestressed concrete composite girder bridge with corrugated steel webs and the bridge belongs to Zhengzhou Longhai Road Fast Track Project at Chang-zhuang reservoir in domestic. Under this background, ZLD automaticly continuous launching system is applied to the prestressed concrete composite girder bridge with corrugated steel webs and the construction scheme design, related construction technology and key points is introduced. Engineering practice shows that the advantage is synchronous control, automation, flexible construction, the force of incremental launching can be adjusted according to level of reaction force and deformation at the pier top. The construction efficiency, safety and reliability is improved for launching engineering, and it has a wide application prospect.
