Our roadheader is a new and advanced tunnel construction machine, which uses rotary tools to excavate and break the surrounding rock and tunneling in the tunnel to form the entire tunnel section.
Under the action of pushing the axial pressure of the oil cylinder, the motor drives the hob disc to rotate, and the rock is cut and crushed, and there is a spoon bucket around it, which is unloaded on the transport belt with the rotation. Hard rock does not need support. When soft rock supports, it can be sprayed, poured concrete or assembled precast blocks.
The machine is economical and reasonable in uniform lithology and over a certain length of roadway. It can be applied to urban subway tunnels, hydraulic tunnels, cross river tunnels, railway tunnels, road tunnels, municipal pipelines and other tunnel projects.
