Abstract: The mountainous expressway has a high bridge-to-tunnel ratio, and the bridge-tunnel is often directly connected. The use of conventional bridge erecting machines is affected by the construction space of the tunnel and the construction difficulty is increased. Taking a certain highway project as an example, introduce the technology of bridge erecting machine through tunnel, beam slab erection in the limited space of tunnel entrance, and beam slab lateral movement technology, successfully solving the operation problem of bridge erecting machine in narrow limited space.
Keywords: roads; tunnels; beam slab erection; bridge erection machine; limited space; construction
