钢波纹管涵加固技术在高速公路中的应用

On consolidation of steel corrugated pipe culvert on expressways

结合广明高速广州段既有涵洞加固工程实例,介绍了钢波纹管涵加固技术原理,从清淤、波纹管安装、封端、注浆等方面,阐述了钢波纹管涵加固施工技术,指出钢波纹管涵具有延性好、变形能力强、施工周期短等优点,应用前景十分广阔。

Combining with the existing culvert consolidation project of Guangzhou section along Guangzhou-Gaoming expressway,the paper indicates the principle for the consolidation technique of steel corrugated pipe culvert,illustrates it construction technique from the desilting,installation of corrugated pipe,end sealing and grouting,and points out the culvert has better ductility and strong deformation with short construction periods,so it has broad application.
