摘要： PROBLEM TO BE SOLVED: To eliminate an overlapping excavation area and to control cutters, independent from one another. SOLUTION: A plurality of first cutters 2a, 2b adapted to be rotated for excavating a working face, are arranged in one and the same plane with a predetermined space therebetween, and a swingable second cutter 3 is provided in a place other than rotating areas of the first cutters 2a, 2b. The second cutter 3 is provided so as to be axially movable from a position in a plane the same as the plane of the first cutters 2a, 2b. When the second cutter 3 is axially shifted with respect to the first cutters 2a, 2b, its swingable range is widened or is rotationally driven.

摘要： PROBLEM TO BE SOLVED: To provide a cutter structure for a shield drilling machine with a bit having a longer life by preventing the wear of the backs of positively and revesely running bits. SOLUTION: When a cuter rotor 9 is driven to a positively running direction A, a positively running bit 20 provided on an oscillator 13 cuts a facing 21 and the oscillator 13 subjected to its reaction is inclined backward in a seesaw manner so that a reveresely running bit 22 is separated from the facing 21. When the cutter rotor 9 is in turn driven to a reversely running direction B, a reversely running bit 22 provided on the oscillator 13 cuts the facing 21 and the oscillator subjected to its reaction is inclined to the opposite direction in a seesaw manner so that the positively running bit 20 is separated from the facing 21. In this way, the wear of the backs of the bits 20, 22 is prevented and the life of the bits 20, 22 are extended. The oscillator 13 is automatically inclined by the erection of the bits 20, 22 from the facing 21, thus to basically require on special actuator.

摘要： PROBLEM TO BE SOLVED: To improve the strength and execution by providing a loading block to mount on and fix to a cutter frame a holder of a roll cutter in an attachable/ detachable manner. SOLUTION: During the execution, a projected part 50c of a positioning member 50 is inserted in a clearance 47 between loading blocks 45, 46, so that a projected part 50a abuts on an upper surface of projected parts 34a, 35a of a holder 32, a tightening piece 60 is inserted in a through hole 46a of the block 46, and screwed in a screw hole 50d in the manner 50 to fix a roller bit 30 to a roller bit support part 40. In a case of the overbreak for executing a curved part, the tightening piece 60 is detached, the bit 30 is moved inwardly together with the member 50, and the bit 30 is moved inside an excavator and drawn from the support part 40. After an expansion space of the bit 30 is formed through the ground aside the excavator, the bit 30 is moved outside from the inside of the excavator through the clearance 47, 48, and fixed to the block 45 by the tightening piece 60. The tightening piece can be prevented from being damaged, and the roller bit can be easily exchanged from the inside.

摘要： PROBLEM TO BE SOLVED: To prevent an interference in an entrance of a projection formed to a shield frame when the entrance is excavated to a new material concrete wall by a cutter and start and arrival are conducted by installing the rotary driving type cutter in front of the projection to the outside in the shield frame. SOLUTION: In the slurry type shield machine, a rotary driving type cutter 30 such as a drill device is mounted in front of a projection 16 such as the device of back-filling continuously while shoving in a shield frame 10. A rotary internal cylinder 36 for cutting is rotated to an external cylinder casing 39 by a rotary driving device 40 such as a motor, and a place corresponding to the projection 16 of a new material concrete wall forming the peripheral section of the entrance of a shaft retaining wall is cut by a cutter bit section 37, in which a plurality of bits 46 are set up to a crossed spoke 45 fitted at the front end of the rotary internal cylinder 39 for cutting. Accordingly, the damage of the entrance and, on the contrary, the damage of the projection due to an interference in the entrance of the projection such as the device of back-filling continuously while shoving can be prevented.

摘要： PURPOSE: To form no projection on the outer peripheral face of a skin plate by providing a back-filling material passage and a coagulant passage in parallel in the skin plate, and opening the outlet sections of the passages adjacently to the rear end section of the skin plate. CONSTITUTION: Injection ports 39 of check valves 26 injecting a back-filling material and a coagulant are adjacently provided to face a tail void section 42, and the back-filling material and the coagulant from the injection ports 39 are mixed immediately after they are injected to the tail void section 42. When a back-filling material passage 4 is clogged, the passage is switched in sequence, and a couple of a coagulant passage 5 and the back-filling material passage 4 are invariably used. When all back-filling material passages 4 are clogged, another injection unit is used for similar actions. The check valve 26 opened by the prescribed pressure or above is provided at a large-diameter section 27, and the coagulant injected from an outlet section is prevented from flowing back and infiltrating into the unused back-filling material passage 4. When the unused back-filling material passage 4 is newly used, the solidification reaction in the passage 4 can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a cutter structure for a shield drilling machine with a bit having a longer life. SOLUTION: Plural main bits 14 placed at preset spaces to a radial direction are mounted on a cutter rotor 10 provided on a shield mainbody, and sub-bits 17 are respectively mounted between the main bits 14. Plural bit columns 20 formed with the main bits 14 and the sub-bits 17 along the radial direction are radially provided from the rotation center of the cutter rotor 10 and the sub-bits 17 of the bit columns 20 adjacent thereto are located on the same radius of the main bits 14 of the bit columns 20. In this way, the mounting numbers of bits 14, 17 is almost doubled than usual and the same number of lines to be drilled as the number of the bit columns 20 is obtained, thereby to reduce the burden of the bits 14, 17, make a slow wearing speed and promote the longer life of the bits 14, 17.

摘要： PROBLEM TO BE SOLVED: To provide a shield drilling machine with a bit having a long life by preventing the wear of the backs of positively and reversely running bits. SOLUTION: When a cutter 6 is first positively rotated A to frill a facing 5, only a positively running bit 16 formed higher has contact with the facing 5 and a reversely running bit 18 formed lower is prevented from being pushed against the facing 5, so that the wear of the back of the reversely running bit 18 is restricted. Then, the positively running bit 16 is worn to a level similar to that of the reversely running bit 18 and the cutter 6 is reversely rotated B to drill the facing 5 so that the reversely running bit 18 left not to be worn at its back in turn drills the facing 5 to thereby avoid useless wear of the bits 16 18 and extend the total life of the bits 16, 18.
