| Abstract: | In light of the low-lying,shallow buried condition and the low hole in the Ganzhou to Longyan Railway in Meihuashan Mountain Tunnel,horizontal directional drilling is used which can complete 60 meters long pipe shed advanced support by one-time,which can effectively solve the problem of large-pipe-shed lap and work space in ultra shallow buried,provides reference for similar mountain tunnel construction of super shallow buried. |
