In Long-span bridge construction by incremental launching method ( ILM for short ), because its complex structural loads, the dragging-type launching equipment commonly used at present no longer applies. Based on Jiubao bridge construction project, a new launching system of the Automatic Walking-type Launching System ( AWLS for short ) is developed. This paper mainly introduces and describes the operation principle, component, main technical performance and features of the AWLS. The 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 the AWLS, Jiubao Bridge was successfully erected by ILM for the first time as a three-span beam-arch composite bridge in the world. Meanwhile the AWLS can be widely used in construction of bridges with various kinds of structures due to its very wide generality. |
