注浆加固技术在桥头跳车处理中的应用

Application of Grouting Reinforcement Technology in Bridgehead Jump Treatment

桥头跳车问题在广西等南方地区的公路建设和运营中较为常见,文章结合武平高速(S52)马平段小桥涵桥台台背注浆加固施工实例,从注浆材料及配合比设计、压力注浆参数的确定、注浆加固施工技术要点三个方面,分析了注浆加固技术在处治桥头跳车中的具体应用。

The problem of bridgehead jumping is common in highway construction and operation in Guangxi and other southern regions.Combining the Xiaoqiao culvert abutment back grouting reinforcement construction example of Maping section in Wuping Expressway （S52）,and from the aspects of grouting material and mix ratio design,determination of pressure grouting parameters,and technical points of grouting reinforcement construction,this article analyzed the specific application of grouting reinforcement technology in bridgehead jump treatment.
