长大隧道机械化配套快速施工技术

On speedy construction technique for mechanization matching for long tunnels

以三都隧道出口施工机械化配套为例,介绍了机械化配套施工方案,对隧道开挖、喷射混凝土、仰拱等施工机械配套技术进行了阐述,以加快施工进度,确保施工安全及质量。

Taking the mechanization matching of Sandu Tunnel entrance construction as the example, the paper introduces the construction scheme for the mechanization matching, and illustrates the techniques for the mechanization matching, including the tunnel excavation, the sprayed concrete, and the inverted arch, so as to accelerate the construction progress, and ensure the construction safety and quality.
