摘要： PROBLEM TO BE SOLVED: To provide a shield machine which facilitates construction of a flexible structure at a tunnel joint portion, and to provide a method for constructing the tunnel joint portion, using the shield machine. SOLUTION: A shield machine S has a steel shell which includes therein an excavating mechanism (a cutter bit 21 and a cutter 22), a propelling mechanism (a shield jack 31), and an earth discharging mechanism (a slurry feeding pipe 32 and a slurry discharge pipe 33). The steel shell 10 is divided into a hood portion 20, a girder portion 30, and a tail portion 40. In the thus constructed shield machine S, a flexible member (flexible ring K) is interposed between the hood portion and the girder portion, and further the steel shell and the flexible member are for use as tunnel lining members.

摘要： PROBLEM TO BE SOLVED: To provide a shield driving machine capable of inexpensively constructing a large-diameter tunnel and a small-diameter tunnel from a starting shaft. SOLUTION: A separable and self-contained small-diameter shield driving part 2 is integrated at the center of a large-diameter shield driving machine 1 to form a driving machine, and the driving machine is brought in the starting shaft 38. After a tunnel 47 is constructed through the use of the driving machine, the small-diameter shield driving part 2 of the driving machine is pulled to the inside of the machine and returned to the location of the starting shaft 38 via the tunnel 47 in the shield driving machine. The small-diameter shield driving part 2 is provided in a shield frame 7 of the large-diameter shield driving machine 1 in such a way as to be pulled to the inside of the machine. A small- diameter cutter head 21 smaller in diameter than the small-diameter shield driving part 2 is rotation-freely provided for the small-diameter shield driving part 2. The small-diameter cutter head 21 is provided with a large-diameter cutter head 4 for performing excavation in front of the large-diameter shield driving machine 1. The small-diameter shield driving part 2 is provided with a drive device 11 for rotating the small-diameter cutter head 21.

摘要： PROBLEM TO BE SOLVED: To provide a tunnel construction method, which can construct a large- diameter tunnel and a small-diameter tunnel at a low lost from a starting shaft, and to provide a shield machine for use therein. SOLUTION: An auger machine, which is comprised of a large-diameter shield machine 1 and a separable small-diameter shield auger section 2 attached at the center of the machine 1 in a single body, is carried in a starting shaft 38, and a large-diameter tunnel 47 is constructed by using the auger machine. Thereafter, the small-diameter shield auger section 2 of the auger machine is pulled out to the interior of the machine, and then returned via the large- diameter tunnel 47 to the location of the starting shaft 38. Furthermore, a small- diameter tunnel 48 is constructed from the starting shaft 38, using the small- diameter shield auger section 2.

摘要： PROBLEM TO BE SOLVED: To facilitate the manufacture of a segment for a helical cylindrical wall, without increasing its cost, and to reduce the costs of the segment and a mold. SOLUTION: A segment 11 in the form of a circular plate is molded into a shape having a pair of first, parallel mating end faces 12 axially joined together, a pair of second, parallel mating end faces 13 circumferentially joined together, and a pair of third mating end faces 14 formed in such a way that a pair of opposite corner portions within a corner formed by the first and second mating end faces 12, 13 are notched. A helical cylindrical wall is constructed inside an excavated hole by assembling the segments 11 into a spiral shape. The third mating end face 14 of the segment 11 is divided from a diagonal so that it consists of mating faces (a), (b) formed by a plurality of triangular planes.

摘要： PROBLEM TO BE SOLVED: To provide a circumferential direction joint structure for segments in which opening can be suppressed from being generated between segments by looseness in a circumferential direction when coupling the segments.SOLUTION: A circumferential direction joint structure for segments comprises a male joint member 20 and a female joint member 30. The male joint member 20 is provided on an end face 11 of a segment 1 forming the shell of a tunnel and includes an engaging head 23. The female joint member 30 is provided on an end face 12 of the segment 1 and includes a head accommodation recess 32a which can be engaged with the engaging head 23 in an accommodated state and is disengaged from the engaging head 23 in a non-accommodated state. The circumferential direction joint structure for the segments is characterized in that the engaging head 23 is regulated by a regulation member 60 from moving in a retracting direction while being energized by a spiral spring 50 to be retracted, and can be engaged with the head accommodation recess 32 in the circumferential direction by canceling the regulation of the movement in the retracting direction by the regulation member 60 with shifting from the non-accommodated state to the accommodated state in the head accommodation recess 32a.
摘要翻译：要解决的问题：为了在连接段时提供一种可以抑制在圆周方向上通过周向松动而在节段之间产生开口的圆周方向接合结构。解决方案：用于段的圆周方向接头结构包括阳接头构件20和阴接头构件30.阳接头构件20设置在形成隧道壳体的段1的端面11上，并且包括阴接头构件30设置在区段1的端面12上，并且包括头部容纳凹部32a，该容纳凹部32a能够以接合状态与接合头23接合，并且以接合头23的形式从接合头23脱离不适应状态。用于各段的圆周方向接合结构的特征在于，接合头23由调节构件60调节，以便在被螺旋弹簧50通电的同时沿回缩方向移动，并且可以与头部容纳凹部在限位部件60中，通过从头部收容凹部32a中的非收容状态转移到容纳状态而消除在回退方向上的移动的调节。版权所有（C）2013，JPO＆INPIT
