九堡大桥步履式平移顶推与传统拖拉式施工对比分析

Comparative Analysis of Walking-type Horizontal Pushing Technology and Traditional Drag-type Technology for Jiubao Bridge

文章以九堡大桥为例,对新型步履式平移顶推施工与传统拖拉式施工方案进行对比分析,创新性地提出采用"步履式平移顶推装置"三跨带拱整体顶推施工工艺,突破了传统的拖拉式施工。确保了九堡大桥顶推施工质量和施工工期。

This paper takes Jiubao Bridge for example to make a comparative analysis of the walking-style horizontal pushing technology and the traditional drag-type construction technology. The innovative use of ＂walking-style horizontal pushing technology＂ to install three spans with arches in one process makes a breakthrough of the traditional drag-type construction technology and ensures the quality of the bridge construction and the completion of Jiubao Bridge within the specified construction period.
