摘要： PROBLEM TO BE SOLVED: To provide a new eccentric multi-axis excavator allowing a cutter frame to be attached easily and securely. SOLUTION: One end 3a of a support beam 3 of this eccentric multi-axis excavator is oscillatingly connected to the cutter frame 2 side through oscillating mechanism 11, and the inner diameter of a fit-in hole 4a of a rotor 4 to which the other end 3b of the support beam 3 is fit-in connected is made larger than the outer diameter of the support beam 3. The support beam 3 is therefore oscillated optionally in vertical and lateral directions with the cutter frame 2 side as an axis, and a suitable clearance is formed around the other end 3b of the support beam 3, so that the cutter frame 2 can be attached easily and positively even with slight dislocation between the support beam 3 and the fit-in hole 4a of the rotor 4.

摘要： PROBLEM TO BE SOLVED: To provide a new eccentric multi-axis excavator that can effectively permit the displacement of a cutter frame while facilitating distribution of a control line. SOLUTION: A guide pipe 20 inserting a control line L through to guide it is laid between a cutter frame 2 and a bulkhead 7. One end of the guide pipe 20 is rotatably journalled to the bulkhead 7 side, and the guide pipe 20 is bent to decenter the other end by the distance R of the rotating radius of the cutter frame 2 and to journal the other end to the cutter frame 2 side. The control line L is therefore distributed easily, and the axial and diametrical displacement of the cutter frame 2 is effectively permitted.

摘要： PROBLEM TO BE SOLVED: To provide a new eccentric multi-axis excavator that can effectively permit axial and diametrical displacement generated to a cutter frame. SOLUTION: A rotating cylinder 22 of a bulkhead 7 is provided with an eccentric pipe 26 for making a control line L pass through to the cutter frame 2 side, and the cutter frame 2 is provided with a guide pipe 30 for guiding the control line L extended from the eccentric pipe 26. A clearance permitting the displacement of the guide pipe 30 is formed at a fitting part R between the end of the guide pipe 30 and the end of the eccentric pipe 26. The axial and diametrical displacement of the cutter frame 2 is therefore permitted effectively so as to avoid adverse effect on the rotating cylinder 22 and the bulkhead 7.

摘要： PROBLEM TO BE SOLVED: To simplify a structure by providing a penetration ring that can project forward in the front potion of a machine body and extruding the penetration ring from behind with a shield jack. SOLUTION: A penetration ring 18 is arranged in the front portion of the body 2 of a jacking machine 1 on the extrusion side. To force the ring 18 out, after a shoe 27 which is made to contact a segment 6 is fixed to the body 2 by extending an extrusion shield jack 22, and the fixed condition of the shield jack main body 23 with the body 2 is released. And then, after a clearance is made between the main body 23 and the ring 18 by shrinking the jack 22, the jack 22 is extended by fixing a connecting rod to a rod 30 in the rear portion of the ring 18, and the ring 18 is extruded by extruding the main body 23 forward. And then another connecting rod is spliced to the rear portion of the connecting rod by shrinking the jack 22, and the ring 18 is extruded repeatedly by extending the jack 22, and the ring 18 is inserted into the penetration room of the facing shield boring machine on the reception side. Therefore, it is possible to reduce costs by omitting a jack exclusive for extrusion.

摘要： PROBLEM TO BE SOLVED: To prevent interference with an entrance of a projection by providing a fixing cutting blade frontward of the projection to the outside of a shield frame. SOLUTION: A fixing cutting blade 30 is provided frontward of a projection 16 such as a simultaneous back-fill agent injector in a shield frame 10. The entrance peripheral part of the shaft earth retaining wall of a starting shaft and a reach shaft is formed by using a new material concrete wall. The cutter 11 of the edge of the shield frame 10 of a shield excavator 3 directly excavates a new raw material concrete wall, so that in the case where an entrance is formed, a fixing cutting blade 30 attached to the shield frame simultaneously excavates at a position corresponding to the projection 16 such as a simultaneous back-fill agent injector of the new raw material concrete wall. Thereby when the shield cutter 3 is passed in the portal excavated by the cutter 11, the projection 16 interferes with the entrance to damage it, and reversely the projection 16 is prevented from being damaged.
