SOLUTION: A wire net 7 is arranged on an inner surface of a bottom wall part 6 of a chute 4. The wire net 7 is inserted into a plurality of support pieces 8 projected from the bottom wall 6 from an upper part in an attachable/ detachable manner, and slightly raised above the inner surface of the bottom wall part 6. The excavated stuff 9 such as earth and sand to be kept on the inner surface of the bottom wall part 6 is evenly kept making use of the mesh of the wire net 7. When the excavated stuff 10 produced during the excavation is charged into the chute 4, and carried out on the downstream side, the excavated stuff 10 slides down over the excavated stuff 9. A plurality of baffle plates are provided on the inner surface of the bottom wall part 6 in a crossing manner in place of the wire net, or a plurality of baffle plates are alternately projected from each side wall part 5 of the chute with the prescribed intervals in the discharging direction.
