摘要： PROBLEM TO BE SOLVED: To simplify a driving system by providing a short cutter having length reaching a minor axis part from the center of a flat hole and excavating a circular hole by swinging or rotating around the center, and a long cutter having length reaching a major axis part from the center of the flat hole and excavating the outside part of the circular hole by swinging around the center. SOLUTION: A short cutter 22 has length L, reaching a minor axis part 19a from the center O of a flat hole H2 , and a long cutter 23 has length reaching a major axis part from the center O of the flat hole H2 . The short cutter 22 and the long cutter 23 have the same rotational center O. A circular hole H1 is excavated by the short cutter 22 around the center O, and the remaining outside part is excavated by the long cutter 23. These cutters 22, 23 are driven around the same center so as to be drivable by the same means. A driving system can therefore be simplified.

摘要： PURPOSE:To carry out a construction work, using only one kind of segment, by spirally assembling segments, shifting little by little to the working face side, of which planes are formed warp with a specified curvature and cut at two corners not adjacent to each other. CONSTITUTION:Segments, of which plane 11 is formed warp with a specified curvature and cut at two corners not adjacent to each other, are connected to be spiral around the axis of a shield machine 2, while being shifted little by little to the working face side. Next, segment rings and segments 1 are connected by bolts and adjacent segments 1 and planes 11 are surface-contacted to connect with each other for assembling. The shield machine 2 is pushed forwards by means of the reactive force of the segment 1 by the forwarding jack, while the segments are assembled.

摘要： PURPOSE:To make excavation easier by a method in which a guide wall having a central hole to be inerted with a shield excavator is provided from the ground's surface and a supporter is provided through support legs and a support jack on the guide wall. CONSTITUTION:A cylindrical guide wall 1 of concrete is constructed from the ground's surface, and a central hole 3 of a sufficient size to insert a shield excavator in a downward attitude is also formed. Support legs 4 and a support jack 5 are provided, and a disc-shaped supporter 6 is also horizontally attached. Arms 7 are projectionally provided, the excavator 2 is hung down through a lowering jack 8, and the jack 5 is expanded or contracted to unblock the legs 4 for downward excavation.
