摘要： PROBLEM TO BE SOLVED: To absorb a compression force, in a tunnel axis direction, acting on a segment of a shield tunnel.SOLUTION: A steel segment 1 comprises main girders 2a, 2b, joint plates 3, 3, a skin plate 4, a longitudinal rib 5 and a stopper mechanism 6. The joint plate 3 connecting terminal portions of the main girders 2a, 2b with each other are divided into two joint plate members and between these members, a joint connecting plate is interposed. The skin plate 4 is divided into two skin plate members and a cover plate is disposed to cover a gap between these members. The longitudinal rib 5 connects the main girders 2a, 2b with each other between the joint plates 3, 3. One end of the stopper mechanism 6 is connected to the main girder 2a and the other end thereof has a clearance of a predetermined distance L between the other end and the main girder 2b. In the case where a compression force in a tunnel axis direction acting on the steel segment 1 is a predetermined value or more, the longitudinal rib 5 is buckled plastically to absorb the compression force. When plastic buckling of the longitudinal rib 5 is advanced and the stopper mechanism 6 is brought into contact with the main girder 2b, the stopper mechanism 6 supports the compression force.

摘要： PROBLEM TO BE SOLVED: To provide a construction method for an intermediate shaft wherein a shaft is formed economically in a short construction term at an intermediate position of a shield tunnel, and also to provide the intermediate shaft. SOLUTION: A continuous underground wall 7 is formed at an intermediate position of an existing tunnel 2 to improve the ground 5 in the vicinity of a lower end part of the continuous underground wall 7 as required. An opening part 4 is formed in the continuous underground wall 7 in a join part of the existing tunnel 2 and a tunnel 6 which is a branch pipe. The ground 1 on an inner side of the continuous underground wall 7 is digged down to the ground 1a, 1b by removing a part of a segment of the existing tunnel 2. The segment is removed in a part shown by a broken line in the existing tunnel 2, and the segment 3 is left in the vicinity of a bottom part shown by solid line to complete excavation. Next, a beam end part 11a and a side wall part 13a are formed between an end part of the segment 3 in the vicinity of the bottom part of the existing tunnel 2 and the continuous underground wall 7, thereby to integrate the segment 3 with the continuous underground wall 7.

摘要： PROBLEM TO BE SOLVED: To increase the workability, by connecting a working carrier on the main girder to a wagon stretched to the front end of the main girder and forming separate base frames in which vertical and horizontal reinforcements are arranged, on the working carrier and thereafter, superposing both base frames with each other to form a cage. SOLUTION: A wagon 1 is provided at the outside of the front end of an existing main girder 3 and 8 working carrier 2 is connected to the wagon 1 to arrange it on the front end of the main girder. Then, a vertical reinforcement base frame with vertical reinforcements and a horizontal reinforcement base frame with horizontal reinforcements are separately formed on the carrier 2. Then, the vertical reinforcement base frame is transferred to the position of the horizontal reinforcement base frame and superposed with each other and the vertical and horizontal reinforcements are assembled to form a steel rod cage 14 by use of a crane 4. And the steel rod cage 14 is transferred to the front end of the main girder 3 by the crane 4 and installed at every block on the basis of a specified position and order and complementary reinforcements are assembled and arranged. And further, concrete is placed in the main gierder by use of automatically extensible forms after arrangement of reinforcements. In this way, construction works can be rapidly executed and the cost can be reduced.
