Research on the Automatic Walking-Type Launching System Applied in Jiubao Bridge Construction

Abstract:

In Long-span bridge construction by incremental launching method, due to its quiet heavy launching weight, long cantilever and complex structural stress. The dragging-type launching equipment commonly used at present no longer applies. Based on Jiubao bridge project, a new launching system of Automatic Walking-type Launching System (AWLS) was developed. This AWLS is a self-balancing launching system that integrates with functions of lifting, pushing and rectifying. It features highly automation, safety and reliability in operation. By using this system, Jiubao Bridge was successfully erected by incremental launching method for the first time as a three-span beam-arch composite bridge at home and abroad.
