正常通车条件下注浆加固板梁铰缝技术研究

Research on the jointjoint technology of normal open grouting reinforcement plate beam

为了缓解高速公路桥梁养护过程中断道施工带来的交通疏导压力,成都绕城高速公路(含东段、西段)第一批次6座桥涵病害维修处治,探索性采用不中断交通进行板梁铰缝加固施工,既有效保证了交通顺畅,又确保了养护工作顺利完成。

Alleviate the traffic congestion pressure brought by the construction of the highway bridge maintenance process, the first batch of 6 bridge and culvert diseases in Chengdu Ring Expressway(including the eastern section and the west section), and explore and adopt uninterrupted traffic for the beam slab hinge The joint reinforcement construction not only ensures the smooth traffic, but also ensures the smooth completion of the maintenance work.
