Construction Technology of Tunnel Lining Vault Embedded Pipe Timely Grouting
摘要
In order to solve the grouting problem of tunnel lining vault cavity and local uncompacting, based on the project example of Qing-shiling tunnel and Yin-dongxia tunnel of Baoping Expressway, combined with the existing tunnel vault grouting construction technology, a construction method of embedded pipe grouting for tunnel lining vault is proposed, and the key construction technology and the best parameter index of pipe grouting are given. The engineering practice proves that the grouting method has good construction effect and can provide technical reference for similar tunnel lining defect treatment construction.
