A tunneling device for performing a series of processes such as excavating, mucking, and lining sequentially from a face side in a tunnel and at the inlet of the tunnel, comprising a sheet truck (7), an arch center (8), and a continuous belt conveyor (5) for discharging excavated muck (3), wherein the continuous belt conveyor (5) is divided into three districts: the front and rear portions of the sheet truck part and arch center part designated as tunnel supported districts supported from the tunnel (1) side (timbering district (1a) and lining district (1c)) and the other designated as a non- tunnel supported district not supported from the tunnel (1) side (water- proof sheet district (1b)) so that the conveyor can pass through the sheet truck part and the arch center part, whereby, when the continuous belt conveyor is used for discharging muck in tunneling, a lining operation can be performed simultaneously with an excavating operation (muck discharging operation), rapid tunneling is enabled, safety in the tunnel can be increased remarkably, and a clean environment in the tunnel can be achieved. |
