Slip-loading device of slide belt conveyer springing-out type

PURPOSE: To enhance working efficiency in an NATM process by providing a springing-out conveyer which extends from a position above a refuse separating screen provided on a frame which slides on a rail toward a face plane. CONSTITUTION: A screen C for separating muck from concrete refuse is provided on the tunnel opening side of a frame A adapted to slide on a rail 1 laid in a tunnel. A springing out belt conveyer E is extended from a position above the screen C toward a face plane. Then excavated sediment is directly shifted from back-horn shovels E, F into pockets 11 of the belt conveyer, and is divided by the screen C so as to be carried and delivered by means of a slip carrying steel vehicle B and a concrete refuse collecting steel vehicle D.
