近几年,国家大力建设基础工程,交通工程的建设遍布全国,道路与桥梁的施工全国随处可见,预应力技术由于其耐久性、安全性等各方面都具有一定的优势而被广泛应用于路桥工程的施工中。文章主要从预应力筋下料制作、预应力筋安装、预应力张拉、孔道压浆几个方面,分析了路桥工程中预应力技术的施工要点,以供参考。 In recent years, the state has made great efforts to construct basic projects, and traffic engineering has been built all over the country. The construction of roads and bridges is ubiquitous across the country. Prestressed technology is widely used in roads and bridges due to its durability, safety and other aspects. Construction of the project. The article mainly analyzes the construction essentials of prestressing technology in road and bridge engineering for reference for the production of prestressing tendons, prestressing tendons installation, prestressing tensioning and pore pressure grouting.
