锚网喷及W钢带支护在隧道衬砌加固中的应用

The Application of Anchor Net Spray and W-type Steel Strip Support in Tunnel Lining Reinforcement

结合浙赣铁路周里冲隧道衬砌开裂加固实例,介绍了针对电气化大断面双线隧道衬砌开裂加固,通过采用注浆锚杆和W钢带以及喷射钢纤维混凝土等新材料和新技术,取得了良好的整治效果。

Combined with the reinforcement of tunnel lining cracks in Zhoulichong Tunnel of Zhejiang - Jiangxi Railway, the reinforcement for lining cracks in electrization large cross section double track tunnel are introduced. New materials and techniques such as grouting anchor rod, W - type steel strip and sprayed steel fiber reinforced concrete are adopted and obtained a better repairing effect.
