摘要： PROBLEM TO BE SOLVED: To easily construct a peripheral wail and shorten a construction period for a tunnel with a large cross section by connecting each other neighboring cylinders in extremely easy way. SOLUTION: Joint tools 24 which have a pair of locking portions 26 with locking strips 26a formed as hooks to be mutually opposed are mounted on connection rods protruded from cylindrical walls. A connection tool 25 for which engagement portions 27 to be inserted into engagement spaces 28 between the locking portions 26 of the joint tools 24 are mounted on both sides of a connection tool mainbody 29 is mounted in such a marmer that the engagement portions 27 are inserted in the engagement spaces 28 between the joint tools 24. The engagement portions 27 of the connection tool 25 being inserted in the engagement spaces 28 between the joint tools 24 are formed large enough for somewhat of clearance therearound. Sealing materials 30 are mounted between the joint tools 24 and at the lower side between the joint tools 24 to fill grout material 31 in the inside spaces.

摘要： PROBLEM TO BE SOLVED: To use the flexible cross sectional sections of adjacent underground structures in common by arranging flexible face members onto one cross sections of the structures at the time of the construction of a plurality of the underground structures and executing the flexible face members in a specified process. SOLUTION: When a plurality of the underground structures 1 are built under an adjacent state, flexible cross sectional sections 2 consisting of flexible face members 4 such as a rubber are provided around the end sections of each structure 1. The face members 4 are formed in a U-shaped sectional form, and beltlike plane sections are used as cutoff sections while both-side edge sections are fixed at the end sections of the structures 1 by bolts, etc. A hardener is injected to a ground among the adjacent structures 1, parts of the face members 4 connecting the structures 1 are removed, and the cross sectional sections 2 are excavated and continuous spaces are formed among the structures 1. The face members 4 are coupled among the structures 1 in the spaces, and flexible sections are formed among the adjacent structures 1. Accordingly, deformation can be absorbed easily even when uneven settlement and an earthquake or meandering and rolling, the fluctuation of a distance and height, etc., at the time of the construction of the underground structures are generated, and cutoff properties can be improved.

摘要： PROBLEM TO BE SOLVED: To reliably connect shielded tunnels to each other even if they are dislocated by fastening mutual segment pieces by bolts through wedge-shaped washers to funnel-shaped holes bored in extremely thick plates of segment end parts of the tunnels. SOLUTION: Extremely thick plates 2 are installed in connecting end parts of segments of shielded tunnels. Inserting holes 3 penetrating through the extremely thick plates 2 are arranged at prescribed intervals in the extremely thick plates 2. One end parts of the inserting holes 3 are formed as tapering funnel-shaped holes 4. Wedge-shaped washers 5 are arranged in the funnel-shaped holes 4, and are fastened by nuts 6. Connecting bolts 7 connect segments 1 and 1 to each other. Therefore, they can be installed with respect to the axis of the connecting bolts 7 with a degree of freedom, and the wedge-shaped washers 5 can be brought into close contact with the funnel-shaped holes 4 by a wedge effect by fastening the nuts 6.

摘要： PROBLEM TO BE SOLVED: To propel excavation without exerting influence on a peripheral im proved layer and a structure by generating lateral force by installing a lateral force absorbing member on a surface on the side where a shield machine is close to an improved foundation and an existing structure. SOLUTION: Grout is injected into a periphery while propelling excavation by a preceding shield machine 1, and a foundation improved layer 12 is constructed on a periphery of a preceding tunnel 11. Excavation is propelled by a succeeding shield machine 2 while shaving a part of the foundation improved layer 12 in a condition adjacent to the preceding tunnel 11. A lateral force absorbing member 21 is installed on a surface contacting with the preceding improved foundation 12 on a periphery of the succeeding shield machine 2. As the lateral force absorbing member 21, a Teflon plate having a small friction coefficient is used, or abrasion resistant paint is applied, or a resilient face member such as hard rubber and urethane is installed. Excavation propulsion force of the shield machine 2 acts forward, but does not act in the vertical and lateral direction, and the occurrence of a crack or the like in the improved layer 12 can be restrained.

摘要： PROBLEM TO BE SOLVED: To construct an underground structure without being influenced by the ground by connecting the peripheral parts of a large number of adjacent tunnels, placing concrete inside to integrate them, and then dismantling a center tunnel group to arrange a new construction. SOLUTION: A large number of shield tunnels are constructed adjacently by a shield machine. The tunnels are constructed being arranged larger than the whole cross section of a predetermined underground construction 5 and being dispersed in a range of surrounding the outside. After soil improvement with a hardener and the like, segments 2 at side walls, floors and ceiling parts of a tunnel group at a peripheral part are dismantled, and the peripheral tunnel group is connected. Concrete 4 is successively placed in space areas for filling. Segments 2 of a tunnel group at a center part are then dismantled, and the underground construction 5 such as a large underground parking garage and an underground road is constructed in formed space. With such processes adopted, a large-scale underground structure is constructed without having any influence on the peripheral part.

摘要： PROBLEM TO BE SOLVED: To erect a conveyed segment into a specified position of a tunnel internal wall by providing a rear part of an excavator body with a vertical moving body, a horizontal moving body, a longitudinal moving body, a turning body and a rotating body, and providing the rotating body with a grip. SOLUTION: Vertical guides 31 are provided on both lateral sides of a support wall 22 of a rear drum 13 so as to support a vertical moving body 32. Lateral guides 34 are formed at the vertical moving body 32 so as to support a lateral moving body 35 movably. A longitudinal moving body 38 is movably supported to the lateral moving body 35 by a longitudinal rod. A turning body 41 is supported to the longitudinal moving body 38 through a bearing so as to be turnable around an axis parallel to an excavating direction. A support cylinder 43 is fixed to the turning body 41, and a moving cylinder 44 is movably fitted to the support cylinder 43. A rotating body 48 is rotatably supported to the moving cylinder 44 by a rotating shaft 47 through a support body 46. A grip is mounted to the rotating body 48 so as to be able to hold a segment. The grip is thereby moved, turned and rotated in three directions in a tunnel so as to easily erect the segment.
