摘要： PROBLEM TO BE SOLVED: To muck debris from tunnel of a small section efficiently. SOLUTION: A plurality of muck cars 20 running forward and backward in prescribed allotted sections are allocated on tracks between the vicinity of a face 2 of a tunnel extended with the advance of the face and a pithead 8 of the tunnel. The muck produced at the face 2 is put in a container bag 10 which is brought into the vicinity of the face 2 and set temporarily in a folded state. The container bag 10 fully loaded with the muck is carried toward the pithead 8 by the muck car 20 waiting at a starting point A. The container bag 10 is transferred from the muck car 20 arriving at a load transfer point B, the terminal of the prescribed allotted section, to the subsequent muck car 20 waiting to run for carriage through the next section. Furthermore, cyclic running wherein the muck car 20 emptied after the operation for transfer returns to the starting point is executed for each of the allocated muck cars 20, and thereby the muck produced at the face 2 of the tunnel is brought to the pithead 8 thereof.

摘要： PROBLEM TO BE SOLVED: To provide a shield excavator which facilitates driving of an enlarged- width pit and taking-up of excavated soil, to thereby shorten a construction period required for construction of a width-enlarged tunnel and reduce construction costs for the same. SOLUTION: The shield excavator 1A is provided with a cutter 2 rotatably supported at a front portion of a shield main body 3, for driving a standard pit of a predetermined cross-sectional area. The shield excavator 1A is comprised of a width-enlarging cutter 4 which is protrudable from an external portion of the shield main body 3 in a direction that widens the width of the standard pit. The width-enlarging cutter 4 carries out driving of the enlarged- width pit, and taking-up of excavated soil of the enlarged-width pit into the shield main body 3.
