悬臂式掘进机在小断面、长隧洞中的应用

Application of Cantilever Tunneling Machine in Small Section and Long Tunnel

以EBZ160型悬臂式掘进机在毗河供水工程新生灌区长沟隧洞的施工为例,介绍了在小断面、长隧洞中悬臂式掘进机和钻爆施工的方案比选,悬臂式掘进机的设备选择、掘进机施工的应用,所取得的经验可为今后EBZ系列掘进机在特长引水隧洞中的成功应用提供借鉴。

Taking the application of EBZ160 cantilever tunneling machine in construction of Changgou Tunnel of Xinsheng Irrigation Area of Pihe Water Supply Project as an example, the scheme selection between cantilever tunneling machine and drilling & blasting construction in small section and long tunnel is introduced, as well as the equipment selection of cantilever tunneling machine and the application of tunneling machine in construction. The experience gained can provide reference for the successful application of EBZ series tunneling machine in extra-long diversion tunnel in the future.
