摘要： PROBLEM TO BE SOLVED: To easily connect a new tunnel to the side part of an existing tunnel by providing the first and the second cutter device having an endmill type cutter edge in the outer periphery of a face plate of a cutter head and on the face plate. SOLUTION: A cutter head 4 is rotatably provided in the front part of a shield body 2. The first cutter device 7 and the second cutter device 8 severally having an endmill type cutter edge are provided in the outer periphery of the face plate 5 of the cutter heat 4 and on the face plate 5. The cutter edge in each of cutter devices 7, 8 is provided so as to be freely movable ahead from the face plate 5. Thus, a hole can be formed in a reinforced concrete segment composing an existing tunnel, and a new tunnel can be easily connected to the side wall part of the existing tunnel. In the case of usual excavation, even if a reinforcement is buriedly provided in a natural ground, the reinforcement can be easily broken to process the excavation.

摘要： PROBLEM TO BE SOLVED: To prevent lowering of cutting efficiency by burying a large number of cemented carbide made rod type tips harder than a parent material in the orthogonal direction against a cutting surface in the inside of the metallic parent material and forming a plural number of broken grooves along the overall circumference in the longitudinal direction with constant intervals respectively on the rod type tips. SOLUTION: A large number of cemented carbide made rod type tips 11 harder than a parent material 1 are cast in the orthogonal direction against a cutting surface in the inside of the metallic parent material 1. Thereafter, a plural number of broken grooves 12 along the overall circumference are formed with constant pitches in the shaft center direction within a surface orthogonal with their shaft centers on outer peripheral surfaces of the rod type tips 11. Consequently, edges on head end parts of the rod type tips 11 are rounded while cutting, before cutting efficiency drops, the rod type tips 11 are broken on the broken grooves 12 on the extreme head end sides by an autogenous blade function and new knife edges appear, and the cutting efficiency never drops. Additionally, even in the case when a more than specified load is applied on a cutting bit, the rod type tip 11 is broken on the broken groove 12 on the extreme head end side and impact can be absorbed, and it is possible to prevent breakage of the cutting bit itself.

摘要： PROBLEM TO BE SOLVED: To crush and penetrate only penetrated portions made of reinforced concrete, such as the side walls of existing segments connected together, by cutting reinforcement using a plurality of cutter devices, and crushing the concrete using roller cutter main bodies. SOLUTION: A shield excavator, for example, is brought close to an existing segment, running holes are formed using a core drill, and roller cutter devices 41A, 41B are fitted into the holes. Next, a cutter rotating motor is actuated to rotate rotary cutter main bodies 31A to 31G at high speed, and a cutter head 7 is rotated to advance a cutter moving cylinder. Then the rotor cutter main bodies 41A, 41B are moved to the outside diameter side, and reinforcement buried in a structure is cut into predetermined lengths using the rotary cutter main bodies 31A to 31G. Further, concrete is crushed by the roller cutter main bodies 41A, 41B to enlarge the running holes to form large-diameter holes. Through holes are repeatedly formed, and after the cutter head 7 and inner equipment are dismantled and conveyed out, a new segment assembled is connected to the existing segment.

摘要： A rectangular shield excavating machine comprises a quadrangularly tubular shield body having a space for receiving an excavated matter at the front end, a rotor disposed in the space so as to be capable of being rotated onward and backward angularly around an axis extending in the direction orthogonal to a pair of facing exterior portions of the body, and excavating means disposed in the body, drive means for rotating onward and backward the rotor angularly around the axis, and for driving the excavating means. Large gravels contained in the excavated matter are crushed by being put between the rotor and a member defining the space with the rotationally reciprocating motion of the rotor.

摘要： PROBLEM TO BE SOLVED: To establish an outer shell preceding type shield tunnel construction method in which the shell part is in advance excavated in a ring form and a lining is provided in this part for supporting the earth pressure and water pressure from the natural ground reasonably, whereby it is possible to effectively erect the lining and make use of the excavated section. SOLUTION: This shield excavating machine concerned is composed of an outer steel shell 1 and an inner steel shell 2, wherein the outer shell 1 is furnished on the whole periphery with a mildly curved surface in convex form over the whole circumference while the inner shell 2 is positioned confronting the outer with a prescribed spacing reserved in between and has a curved surface 5 swelling inward in four places. In this part, working shaft is formed, and segments carried in therefrom are assembled along the inner surface of the outer shell 1 so that a lining is formed having a mildly curved surface convex outward. Segment(s) for the working shaft is attached to the inside of this lining in the zone with the working shaft and removed along with excavation of the inside of the lining.
