PROBLEM TO BE SOLVED: To provide belt conveyer equipment capable of advancing a bypass part for avoiding interference with a mold device, following an advancing mold device. SOLUTION: This earth removing conveyer equipment for tunnel carries out excavated earth and sand in a tunnel 1, wherein a carrier belt 15 is wrapped and stretched between a movable end roller provided in a rear truck and a fixed end roller in the rear of the tunnel to form a conveyance route. On the front part of a mold device advancing inside the tunnel, a belt route displacement device 10 displacing the carrier belt 15 from an upper position to a lower position and from the outside to the central side by a pair of two sets of reversing rollers 23US, 23DS, 23UR, 23DR is disposed so as to freely advance. A belt storage device capable of sending out the carrier belt 15 is disposed to follow up the belt route displacement device 10 with the advance of the mold device 4.
