Excavation and Construction Technology of Small Section Tunnel Milling Machine
The cross-section of the water conveyance tunnel is small,and the local burial depth is relatively shallow.The traditional blasting excavation process causes significant disturbance to the surrounding rock,poses certain safety production risks,and incurs high costs in the use,management,and construction of initiating explosive devices.Taking into account the geological conditions of the palm face and the actual operating space on site,a tunnel specific milling machine with appropriate performance parameters is selected.It can not only integrate excavation and slag loading,improve construction efficiency,but also minimize disturbance to the surrounding rock and improve the safety and security of construction personnel.
