摘要： PROBLEM TO BE SOLVED: To render the cross-sectional configuration changeable readily by making a pair of reversed C-shape frames into square cylinders, setting them to be movable to and away from each other by rendering its width adjustable by a jack, and attaching cutters being shifted in its rotation phase on the front side. SOLUTION: The excavator main body 11 is formed into a substantial square by fitting frames 12, 13 having its reversed C-shape cross-section, and a pair of upper and lower support sleeves 15, 16 are fastened within the frames 12, 13, and then a width controlling jack 17 is disposed therein. Bulk heads are secured left and right respectively on the frames 12, 13, and rotational shafts 22, 23 are supported rotatably at the front side. On the rotational shafts 22, 23. excavation arms 24, 25 are fixed at both sides in the horizontal direction, and cutters 26, 27 are fastened at the front part. The excavation arm 24 of the rotational shaft 22 and the excavation arm 25 of the rotational shaft 23 are installed by shifting the attachment angle at 90 degrees, and the excavation arms 24, 25 located at the intermediate position are installed in a shifted manner in the upper and lower direction as well. Thus, the frames are made expansible and contractible, and the rotational shafts are rendered movable to and away from each other, so that the tunnel can be changed in its cross-sectional configuration.

摘要： PROBLEM TO BE SOLVED: To enhance the operating easiness for recovering works and enhance the reliance upon waterproofness for the subsurface water pressure. SOLUTION: Bolt(s) coupling the over-part of a sliding member with its under-part is/are removed after the excavating works of a pit 508 are finished, followed by removal of bolt(s) which couple a bearing with a cutter ring. Then a motor 512 for driving cutter, bearing, an upper and a lower jack 530 for cutter, etc., are lifted and collected back to outside the pit 508. The collected motor 512, etc., are hung down to a shield body installed in the longitudinal arrangement and furnished with a bulkhead, and are inserted through a penetration part and fixed followed by installation of other members one after another so that an adit shield excavator is accomplished. This is inserted in a pit while it remains in the vertical attitude and turned in the prescribed position so as to face aside, and thus the preparation for the propulsive excavating operation is completed.

摘要： PROBLEM TO BE SOLVED: To easily inspect and change a cutter bit by mounting a cutter head having many cutter bits so as to be capable of being housing in a rotation body, and rotating the rotation body around a rotational axis orthogonal with the excavating direction. SOLUTION: A hollow and polyhedral rotation body 15 is held in the front barrel 11 of an excavator body along a rotation axis O orthogonal with the excavating direction, so as to be capable of freely turning. In addition, a cylindrical travel body 22 is provided within the rotation body 15, so as to be capable of moving in the excavating direction, and a freely rotatable cylinder 24 is mounted on the front of the travel body 22. In this case, a disc type cutter head 25 is fixed to the cylinder 24 and a cutter bit 26 is fitted to the cutter head 25. Also, the rotation body 15 houses the cutter head 25 and an expansion cutter 29. Then, the rotation body 15 is horizontally turned around the rotation axis O and the cutter head 25 is directed toward a position aft of the excavating direction within the front barrel 11, thereby inspecting the abrasion status of the cutter bits 26, 27 and 30, and implementing the change thereof whenever necessary.

摘要： PROBLEM TO BE SOLVED: To improve sealing performance by installing fixing sections on both sides of a contact sealing section, in which a front end section is narrowed and miniaturized, as sealing devices in spherical bodies, in which cutter devices are housed and which are supported rotatably, in a tunnel excavator. SOLUTION: Sealing materials 1 sealing the external surface of a spherical body 15 consist of gummous beltlike setting seats 3, in which reinforcing cloth 8 such as a woven fabric, knitted cloth, etc., is interposed in layers, contact sealing sections 4 and fixing sections 6. The retaining stages 6a of the fixing sections 6 formed on both side sections of the setting seats 3 are engaged with the engaging projecting sections 2a of fixing members 2 fixed on the excavator main body side, and fastened firmly. Front end sections are formed narrowly and in small size in the contact sealing sections 4, and the internal pressure of cavity sections 5 is adjusted through pressure ports 7 formed to the setting seats 3, and the contact sealing sections 4 are press-contacted with the external surface of the spherical body 15 at high pressure higher than external pressure such as slurry pressure and the spherical body 15 is sealed. Accordingly, the contact sealing sections 4 follow up properly to the displacement of the spherical body 15, and the biting of the contact sealing sections 4 and the damage of the fixing sections 6 are not generated even when the contact sealing sections 4 are brought into contact with the notched end sections of the spherical body 15.
