Ltd.10.26689/jwa.v9i3.10932ArticleResearch on Multi-functional Excavation Trolley for Single-track Tunnel Facehttps://artdesignp.com/journal/JWA/9/3/10.26689/jwa.v9i3.10932ZhangGuangming2025932025-07-01The construction of the tunnel face is a critical aspect of tunnel excavation, and its supporting equipment mainly includes drilling jumbos, arch installation trolleys, wet spraying manipulators, and anchor bolt trolleys. To address the issues of high construction costs and the need to replace equipment for different processes, this paper designs an economical and practical multi-functional integrated trolley based on engineering cases. This trolley is suitable for various construction methods such as full-face excavation and benching method, and integrates functions such as drilling and blasting holes, anchor bolt holes, advance grouting holes, pipe roof construction, charging, anchor bolt installation and grouting, and arch mesh installation. It reduces the number of operators, improves the tunnel working environment, lowers construction costs, and enhances construction efficiency.
