连续刚构桥预应力箱梁施工技术研究

Study on Pre-stressed Box Girder Construction Technology of Continuous Rigid Frame Bridge

预应力施工是连续刚构桥施工中的重点和难点,结合某连续刚构桥工程,系统分析了预应力箱梁施工中的钢筋、预应力筋的加工、绑扎,模板加工及安装,混凝土拌和、浇注和养护,张拉压浆的施工工艺,可为同类桥梁施工提供参考。

The pre-stressing construction is the importance and difficulty in the construction of continuous rigid frame bridge.Combined with a continuous rigid frame bridge project,the article systematically analyzes the construction technologies of the reinforcing bar and pre-stressed reinforcement processing and binding,the template processing and installation,the concrete mixing pouring and curing,and tension grouting,which can be referred for the construction of the similar bridges.
