三角形挂篮的设计与施工

The Design and Construction of Triangular Cradle Scaffolding

随着桥梁设计、施工技术和预应力混凝土技术的飞速发展,悬臂施工的工艺越来越成熟。无水平推力后支点挂篮作为悬臂施工最主要的施工设备,在桥梁建设中发挥着越来越重要的作用。结合白庙北江特大桥的施工实践,对三角形挂篮进行结构设计和承载力校核,并付诸施工,可为同类工程提供借鉴。

Along with the rapid development of bridge design, construction technology and prestressed concrete technology, the cantilever construction technology is more and more mature. The cradle scaffolding with no-horizontal thrust and rear fulcrum, being as the most important construction equipment in cantilever construction, plays a more and more important role in bridge construction. Connecting with the construction practice of the North Baimiao Bridge, this paper makes the structural design and bearing capacity checking for triangular cradle scaffolding and puts into construction, which can provide references for the similar projects.
