空心板梁公路桥梁拆除施工技术

Demolition Construction Technology of Hollow Slab Beam Highway Bridge

结合某公路桥梁拆除工程实例,对该桥梁结合梁拆除采用单片切割、架桥机吊离法施工;对桥墩采取吊车配合线切割、整体吊拆的施工方法。系统介绍该桥梁拆除施工工艺环节,可为同类工程提供参考实例。

This paper combines the example of a highway bridge demolition project. The bridge joint beam is removed by singlepiece cutting and bridge erecting method. The construction method of crane with line cutting and overall hoisting is adopted for the pier. The system introduces the construction process of the bridge demolition and provides a reference example for similar projects.
