摘要： PURPOSE:To excavate a tunnel which is so formed as to have an almost flat lower portion by deciding most part of a tunnel opening using a first cutter face, and surely drilling a front working face with a second cutter face. CONSTITUTION:A first cutter face 10 is installed the outer form of which when seen from the front side is like a fan including a circular portion extending along the upper portion of a tunnel and which has drilling blades 11 and earth inlets 12 radially disposed therein and which oscillates about the center O of curvature of the circular portion. A tunnel opening which is so formed as to have a circular upper portion and a rectilinear lower portion is almost determined by the first cutter face 10. A second cutter face 20 which has drilling edges 21 and earth inlets 22 disposed therein and which rotates or oscillates within an angle range larger than the angle S of oscillation of the first cutter face 10 is installed near the center of the radial arrangement of the first cutter face 10. A front working face is surely drilled by the second cutter face 20.

摘要： PROBLEM TO BE SOLVED: To provide a shield machine for excavating a rectangular cross-section tunnel, which is simple in structure, not long in length, and ensures its stable excavation performance and stable earth removing performance. SOLUTION: According to the structure of the shield machine, four sets of screw cutters 6 are arranged in four corner portions in a chamber 3, and they are driven for rotation by cutter driving mechanisms 8 to excavate unexcavated four corner portions of the tunnel by a cutter disk 5, to thereby excavate the rectangular cross-section tunnel. Then, a mud additive is discharged from a discharge port in a circumferential surface of a drum member of each screw cutter 6 in order to improve the fluidity of excavated earth, and the excavated earth is transferred toward the lateral center of the chamber 3 by rotating the screw cutters 6.

摘要： PROBLEM TO BE SOLVED: To solve problems of a simultaneous backfilling device protruded from a tail plate to cause difficulty in sealing to the simultaneous backfilling injection device in a starting or arrival vertical shaft, and difficulty in cleaning from a backfilling material supply port to a backfilling material injection port by pig. SOLUTION: An injection device main body 1 is integrally provided with a tail plate T to reduce radial protrusion quantity, and a piston rod 6 provided on the injection device main body 1 is set at an opening position (e) for communicating a backfilling material injection port 7 with an opening of a backfilling material supply hole 12 to inject backfilling material to a tail void part B, and at a closing position (f) to close the backfilling material injection port 7, but communicate the opening of the backfilling material supply hole 12 with an opening 13a of a cleaning water supply hole 13 to wash the backfilling material supply hole 12 by washing water. The backfilling material supply hole 12, the backfilling material infection port 7, and communicated openings are formed roughly in similar inner diameters, thereby cleaning of inner walls by insertion of pig P is possible.

摘要： PROBLEM TO BE SOLVED: To apply a method of 'NOMST' construction to departure and arrival shafts by installing an overexcavating device and forming a passing grove for passing a projected projecting section to the outer circumferential section of a shield frame in a shield machine. SOLUTION: In the shield machine 1, an overexcavating device 40 is mounted to a simultaneous back-filling injection device 25 projected from the outer circumferential section of a shield frame 2 and to the front in the direction of excavation of the projecting section of a putty grease injection device 35. The overexcavating device 40 has a rotary type cutter 45 driven by a hydraulic motor 61, and a cutter 45 is lifted and lowered by a pair of hydraulic cylinders 64 and changed over to the place of overexcavation and the places of a retreat and entrance. Accordingly, the shield machine 1 cuts the 'NOMST' wall of departure and arrival shafts by a cutter disk 3 and a passing opening is formed while a passing groove for passing the simultaneous back-filling injection device 25 and the projecting section of the putty grease injection device 35 is formed by the overexcavating device 40, and the contact and damage of the projecting section and the passing opening are prevented.

摘要： PURPOSE:To excavate a tunnel efficiently, by a method wherein the bottom surface of a carrier for carrying construction equipment and materials at the rear of an excavator is formed in the same shape with a segment-made inner wall and the carrier is composed so as to be able to travel without the use of rails. CONSTITUTION:The bottoms surface of a carrier 10 for carrying construction equipment and materials, such as segments Aa, at the rear of a tunneling shield machine 1 is formed in the same shape with a segment wall Ab and traveling wheels 11 are provided thereon. Telescopic arms 12 are provided on the both sides of the upper part of the carrier 10 and prevent the carrier 10 from inclining. The carrier 10 is composed so as to be able to travel on the segment wall Ab without the use of rails. In this way, the excavation of a tunnel can be efficiently performed.
