悬臂灌注连续梁桥预应力通长束施工技术

On construction technique of prestressed threading in cantilever casting continuous girder bridge

结合泰东河大桥工程实践,就悬臂灌注连续梁桥预应力通长束的施工技术进行了论述,分别介绍了预应力孔道成型,通长束的穿束及双控张拉等关键技术,为类似工程提供了指导。

Combining with the engineering practice of Taidonghe Bridge,the paper indicates the construction technique of prestressed threading,introduces some key technique from the prestressed hole forming,the penetrating strand of treading and the double-control tension,so as to provide the direction for similar projects.
