PROBLEM TO BE SOLVED: To efficiently perform a continuous underground wall forming work. ;SOLUTION: A continuous underground wall forming excavator includes two cutter drums 11, 11, a suction device, and a body part 13, and a cut surface cleaning jig 2 is combined with the excavator. With this arrangement, the excavator has a cleaning function. The two cutter drums 11, 11 are parallelly disposed so that rotation axes 111 are disposed parallel to each other below the body part 13 so as to be rotated in opposite directions a, b. A cut surface cleaning jig 2 includes a plurality of brushes 21 and a mount member 22. The bushes 21 are mounted on the member 22 so as to be spaced apart, one from another. The member 22 has flexibility so that it can be wrapped around the outer periphery of the drums 11, 11.;COPYRIGHT: (C)1997,JPO
