摘要
文章简述了拱顶脱空、空洞等缺陷的常规处理方法以及如何预防拱顶脱空、空洞的方法,重点研究了衬砌台车拱顶预埋RPC管与带模及时注浆工艺。通过雷达扫描检测验证,该工艺有效地解决了拱顶脱空、空洞、混凝土不密实等缺陷,提高了注浆材料与衬砌的整体性,确保结构更加安全。
This paper briefly introduces the conventional treatment method for and prevention of the defects of voids at the tunnel crown, and focuses mainly on timely grouting with lining forms and embedded RPC pipe at the crown by a lining trolley. With this technology the problems of a hollow cavity, void and uncompacted concrete are solved and the integrity of the grouting material and lining are improved after being verified by radar scanning, there- by guaranteeing the safety of the structure.
