公路桥梁工程应急加固中新型预应力技术的应用

Application of new prestressing technology in emergency reinforcement of highway and bridge engineering

以某高速公路桥梁应急加固工程为例,从预应力技术应用要求、T梁模板及台座施工、预应力T梁施工以及孔道压浆等方面,论述新型预应力技术在高速公路桥梁工程应急加固中的应用要点,通过分析可知,应用新型预应力技术能够改善应急加固效果,可以提高桥梁的稳定性与安全性。

Taking an expressway bridge emergency reinforcement project as an example,from the application requirements of prestressing technology,T-beam formwork and pedestal construction,the application of new prestressing technology in emergency reinforcement of expressway bridge engineering is discussed in the construction of prestressing T-beam and grouting of tunnel. Through analysis,it can be seen that the application of new prestressing technology can improve the effect of emergency reinforcement and improve the stability and safety of bridges.
