摘要： PROBLEM TO BE SOLVED: To form a tunnel having an arc-shaped cross section via the use of arc-shaped segments of the same shape by applying the constitution that a connecting segment laid between adjacent arc-shaped segments of a tunnel having an arc-shaped cross section is formed to have a larger cross section at external surface than at internal surface. SOLUTION: Three rows of shafts are drilled from the ground. The side wall 52 of a tunnel body structure and a center pillar 53 are erected and the shafts are back filled. A tunnel 21 having an arc-shaped cross section is excavated with an underground excavator 20 so as to connect the upper side between the side wall 52 and the center pillar 53. Then, an arc-shaped segment 41, an upper connecting segment and a lower connecting segment are combined for erecting a pillar segments 46, thereby constructing the tunnel 21 having a circular arc cross section. Thus tunnel 21 has a different curvature between an inner peripheral part and an outer peripheral part and each arc-shaped segment 41 can be formed to have the same shape, when the upper connecting segments is made larger than the lower connecting segment. Internal space is excavated using the constructed top plate, side wall 52 and center pillar 53 as timbering, thereby constructing a tunnel having a large cross section.

摘要： PROBLEM TO BE SOLVED: To simplify the structure of a cutter driving unit by providing a crank in a rear end of a rotary driving body of a cutter unit, and fitting a connecting plate to the periphery of the rear end of the crank, and rotating the rotary driving body with plural fluid pressure jacks. SOLUTION: A rotary driving body 7 of a cutter unit 6 is supported freely to be rotated by a bearing 5 provided in a bulk head 3. A cutter spoke 8 is integrally fitted to a front end of the rotary driving body 7. A cutter driving unit 10 is provided with a crank 11, a connector 11 and plural fluid pressure jacks 18a, 18b, 18c. The crank 11 uses the rotary driving body 7 as a crank shaft, and a crank pin 13 is provided with a deviation by a deviation distance (e). A connecting plate 14 is provided in the periphery of the crank pin 13 freely to be rotated. The fluid pressure jacks 18a-18c are driven so as to push the crank pin 13 through the connecting plate 14, and the rotary driving body 7 is rotated so as to rotate the cutter 6. Structure of the device is thereby simplified without using parts requiring high accuracy such as a pinion and a gear.

摘要： PROBLEM TO BE SOLVED: To locate a roller bit closer to the peripheral edge of a cutter frame, to make the oscillating motion unnecessary, to locate adjacent roller bits closer to each other, to improve the excavating ability and to simplify the construction. SOLUTION: In this underground excavator 21, a surrounding cutter frame 25 is located in a freely rotatable manner through a parallel crank mechanism on the front side of a partition wall portion 23, and a plurality of surrounding roller bits 27 are arranged in a freely rotatable manner through a rotating shaft on the front surface of the surrounding cutter frame 25 in configuration. In this case, the surrounding cutter frame 25 has an umbrella shape having the central portion projected forward, on the other hand, the axis O2 of the rotary shaft of the surrounding roller bit 27 is so arranged as to intersect with the center axis O3 of the umbrella shape.

SOLUTION: Circular arc-shaped members 2, 8 are cylindrically combined to form a tunnel lining body 1. The members 2, 8 are made of a concrete board having a rectangular plan view and a circular arc-shaped cross section, they are framed with a steel member on four sides, and the concrete board is provided with a reinforcing member made of a flat steel or a welded wire net. Guide plates 9, 37 are protruded outward from the steel member in the perpendicular direction to the steel member. No bolt joint is used at the time of assembling, the members 2, 8 are supported by erectors and positioned by the guide plates 9, 37, and execution is accelerated. Steel frame bodies manufactured at a factory are arranged on the circular arc-shaped face of a circular arc- shaped member manufacturing rack, and concrete is placed in the frame bodies to manufacture the members 2, 8. Rigidity is secured, safety can be improved, the members 2, 8 can be quickly manufactured, and the cost can be reduced.
