THQ Bridge Girder Launcher for Tunnels
1.Introduction
THQ bridge girder launcher for tunnels is a kind of new high-speed rail bridging machine to address the problems of many tunnel in the construction of high-speed rail. The whole machine can go through the tunnel carried by the beam-conveying vehicle, not only saving the cost for disassembly and installation of bridge erecting and transport, but also ensuring the construction safety. It can be applied to the bridge erecting in the construction field continually.
2.Features
It can be used for the construction between the bridge and the tunnel, saving the cost for disassembly and installation and improving the efficiency.
The guide beam and the bridge girder launcher direct each other to vertically pierce the hole;easy operation, safety and reliability.
