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： PURPOSE:To automatize fixing operation of rails to sleepers by providing means to move rails in widthwise direction, means to move clip plates, and means for tightening bolt and nut. CONSTITUTION:Sleepers 2 are set on a place where rails are to be set, and clip plates 9 are temporarily fixed to given positions on the sleeper 2 by bolt and nuts. A rail 1A is placed between the clip plates 9, and its position is adjusted in the longitudinal direction to a position where the rail 1A is connected to the end of a rail 1 already set. The widthwise position of the rail 1A is also adjusted by a pusher to move the rail to the widthwise direction, and the clip plates 9 are moved to the position where they are coupled with the bottom of the rails 1A by using a mover to move the plates 9. The temporarily fixed bolt and nuts are further clamped by the clamper for bolt and nut to fix the rail 1A.

摘要： PURPOSE:To maintain the soil in a stable state by making the outer peripheral part of the cutter disk of a shield machine divided in the peripheral direction expandable in the radial direction and the outside diameter of a skin plate almost equal to that of the cutter disk. CONSTITUTION:A tunnel is driven with two shield machines 1 and 2 which respectively make excavate the ground toward a meeting position 76 from both sides of the tunnel and the preceding machine 1 of the two machines 1 and 2 is made to reach the meeting position 76 prior to the other machine 2 and stopped at the position 76. Then the other machine 2 is made to reach the position 76 and the cutter disk 32a of the machine 2 is retreated into a skin plate 34a. After the cutter disk 32a is retreated, the preceding machine 1 is made to get into the skin plate 34a of the other machine 1 and a hardener is injected between the machines 1 and 2. After the hardener hardens, the machines 1 and 2 are dismantled and the inside of segments 19 and 19a in their radial directions are covered with concrete 79. Therefore, caving of the tunnel roof and side walls can be prevented at the time of tunnel driving.

摘要： PURPOSE:To construct the spiral twin tunnels by constituting two continuous ring sections with multiple pieces respectively and twisting both ring sections together at the connection portion. CONSTITUTION:The first connecting piece 13 is used as a common piece, and the second connecting piece 14 and circular arc pieces 15-19 are connected to the connecting piece 13 in sequence counterclockwise on one ring section and clockwise on the other ring section to form circular ring sections 11 and 12. Both ring sections 11 and 12 are twisted in opposite directions to each other to form a segment 10.

摘要： PROBLEM TO BE SOLVED: To improve the cut-off effect, and to efficiently perform the tunnel excavation by providing a hardener discharge mechanism on a cutter disk of a reception side excavator to harden a skin plate, and excavating a piercing side excavator to perform the joining. SOLUTION: When an excavator excavating from each side is joined with each other, an over cutter 11 of a reception side excavator 1 is retracted in the center direction of a cutter disk 4, and the disk 4 is pulled inside a skin plate 13 in a slidable manner by a pull-in jack. The hardener is discharged from a hardener discharge device 17 into an excavation space generated by the pull-in, and the earth and sand is hardened. A piercing side excavator 2 excavates the hardened earth and sand, and proceeds into the reception side excavator 1. Ingress of underground water is prevented by expanding a tube seal 16 on the piercing side. After both excavators 1, 2 are joined with each other (after piercing a tunnel), the excavators are disassembled. Excavation of the tunnel can be efficiently performed.

摘要： PROBLEM TO BE SOLVED: To efficiently allow an excavation both in hard ground and soft ground by making a roller cutter and a cutter bit fitted to a cutter disk mutually exchangeable from the inside on a tunnel excavator. SOLUTION: A cutter holder main body 4a is fixed to the cutter support frame 3 of a cutter disk. A rotary saddle 8 and a spacer 8b are fitted to angular shaft sections protruded on both sides of a roller cutter, the roller cutter is rotatably fitted with the engaging recess of the cutter holder main body 4a, and it is fixed by bolts 9a via a bearing cap 9. When the roller cutter is to be removed, the bolts 9a are loosened, a rotary saddle 8 is rotated by 180', and the roller cutter is extracted to the inside. A cutter bit 11 is inserted into the cutter holder main body 4a in combination with two support members 12, the support members 12 are separated to be locked on stoppers 6 of the cutter support frame 3, and their upper end edges are locked on the lock pieces 4b of the cutter holder main body 4a. The roller cutter and the cutter bit 11 can be exchanged from the inside in response to the excavated ground.
