预应力张拉与压浆是预应力桥梁施工中的两道关键工序,预应力张拉与压浆的施工质量直接关系到预应力桥梁的安全性和耐久性,特别是预制梁管道的压浆饱满程度直接影响到桥梁的寿命。文章主要介绍一种新的压浆工艺——大循环智能压浆工艺。该压浆工艺通过来马高速公路的工程实践证明,效果比较好,值得推广。
Prestressing and grouting are two key processes in prestressed bridge construction. The construction quality of prestressed tension and grouting is directly related to the safety and durability of prestressed bridges, especially the grouting Full extent of a direct impact on the life of the bridge. The paper mainly introduces a new grouting technology - big circulation intelligent grouting technology. The grouting process by Lai Ma freeway engineering practice proved effective and worth promoting.
