摘要
后张法预应力箱梁是高速铁路的重要组成结构,它的预应力位置直接影响着产品质量和寿命。通过对预应力管道定位技术的研究,很好的解决了预应力管道精准布设的施工作业要求,提供了可靠的技术方法和工艺措施,收到了预期的技术经济效果。
The post-tensioned box girder is an important component of high-speed rail structure, and its prestressed position has a direct impact on quality and life of product. Through research on prestressed pipe positioning technology, construction operations requirements to the precise layout of prestressed pipeline is solved, which provide a reliable technical methods and process measures and receive the expected technical and economic effect.
