通风和粉尘治理是隧道施工中的技术难题,采用独头掘进的特长隧道的施工通风问题更是难以得到有效解决。本文通过大坪里隧道的施工实践,介绍了在不同施工里程所采用的施工通风技术。
Ventilation and dust control are the technical problems in the construction of tunnels. The ventilation problems of construction of tunnels with unique tunneling are more difficult to be solved effectively. This article introduces the construction ventilation technology adopted in different construction mileage through the construction practice of Dapingli Tunnel.
