摘要： PROBLEM TO BE SOLVED: To make it possible to excavate easily and in a short period of time a gap between tunnel portions for lining. SOLUTION: After a lining portion 1 having a rectangular cross section is built intermittently around a tunnel, this driving machine excavates a gap 2 between these lining portions 1. A shield main body 13 having a rectangular cross section in response to a rectangular gap 2 between lining portions 2 and a cutter head 21 for excavating an rectangular-shaped hole arranged at a front end portion of the shield main body 13 in a freely rotatable manner are provided; and an end edge of a side skin plate 12 of the shield main body 13 is extended so as to overlap with the side of the existing lining portion 1A respectively, and a cutter device 31 for excavating an outer portion of the existing lining portion 1A is provided at the front end portion corresponding to an extended portion 12a.

摘要： PROBLEM TO BE SOLVED: To make easy to built the corners of the circumferential wall of a large-diameter tunnel by arranging two cutter heads that drive reciprocatingly near a plane perpendicular to the axial center of a shield using a cutter driver comprises of a parallel link manipulator in the front of the main body of the shield with an L cross section. SOLUTION: A cutter driver 4 is comprised of a parallel link manipulator made up of hydraulic cutter driving cylinders 5A to 5H, pairs of extension actuator, the front end of which is connected to a cutter head 2 in a rotatable manner and the rear end of which is connected to the pressure bulkhead 3 of the shield main body 1 in a rotatable manner. The cutter driving cylinders 5A to 5H are extended and retracted by controlling pressure oil that is connected to and discharged from the cutter head driver 4, the cutter heads 2A, 2B move right and left, and up and down reciprocatingly in a plane perpendicular to the axial core of the shield, and cutter bits 34, 35 bore the natural ground. Thus a tunnel having an L-shape cross section can be excavated at a time and corners of the circumferential wall of a large diameter rectangular tunnel can be built in a short time and accurately.

摘要： PROBLEM TO BE SOLVED: To improve the structural strength and cutoff properties of a joint section between tunnels constructed in parallel, and to joint the tunnels flexibly regardless of an error on the execution of works of the tunnels when a section between these tunnels is opened for traffic and formed in integral structure. SOLUTION: When an upper-stage tunnel 11U is built in parallel with a lower-stage tunnel 11L, sheet piles are installed on the outsides of both joint sections. A set of two upper and lower comb-tooth shaped fittings 29U, 29L are interposed to the joint sections while opening both tunnels 11U, 11L for traffic. These comb-tooth shaped fittings 29U, 29L consist of approximately plate-shaped bases 30 and standing plates 31, 31, 31 respectively, and the upper and lower standing plates 31, 31 are engaged and abutted mutually when the bases 30 are fixed at edges on the joint sides of the tunnels 11U, 11L respectively. Since boltholes 34 are bored beforehand to the standing plates 31 of the upper comb-tooth shaped fittings 29U, boltholes 39 are bored to the standing plates 31 of the lower comb-tooth shaped fittings 29L so as to be superposed to the boltholes 34, and the upper and lower standing plates 31, 31 are fixed mutually through these boltholes 34, 39.

摘要： PROBLEM TO BE SOLVED: To increase the strength of connecting sections, and to improve the efficiency of the execution of works by a method wherein the end faces of the main girders of the adjacent segments of a shield tunnel are abutted, and connecting plates are disposed on each both side of flanges and webs and bolted. SOLUTION: Connecting plates 35 are inserted among webs 23, 23, and the bolts 27 of both welding sections 25a and projecting sections 25b of segments 20 made of steel are applied to the internal-surface side joint sections of flanges 22, 22 while being inserted into boltholes 36, and clamped by nuts. Both flanges 22, 22 are coupled by the connecting plates 25 and 35. Other connecting plates 37, 37 are applied to both sides of the joint sections among the webs 23, 23. The boltholes 38 of the connecting plates 37 and the boltholes 24 of the webs 23 are conformed and bolted, and the webs 23, 23 are connected. Accordingly, both main girders 21, 21 are bridged by the connecting plates 25, 35, 37 in joint structure among the segments by the segments 20 made of steel, and bolted while interposing the flanges 22 and the webs 23, thus increasing joint strength.

摘要： PROBLEM TO BE SOLVED: To improve connecting strength without injuring the strength of concrete by alternating, in a joint between tunnel covering body segments, the directions of joint boxes and insert nuts. SOLUTION: Front plates 15, in each of which a bolt hole 18 is formed, are disposed on a joint surface 12L of one of segments 11L. Joint boxes 13 each having a blackout 16 inside the segment 11L are formed inside the plates 15. An insert nut 14 is disposed on a joint surface 12R of the other segment 11R at a position opposite to the bolt hole 18 of the joint box 13. The joint surfaces 12L, 12R are joined together and the hole 18 is combined with the nut 14. A bolt 20 is tightly screwed into the nut 14 from the blackout 16 through the hole 18 to connect both the segments 11L, 11R. The joint boxes 13 and the insert nuts 14 are arranged so as to be alternately oriented along the longitudinal direction of the joint, whereby even if the joint is made tight, failure in cross section can be dispersed and hence high connecting strength can be obtained.

摘要： PROBLEM TO BE SOLVED: To efficiently excavate a rectangular-section tunnel. SOLUTION: Three shield machines 4a, 4b, 4c are layered up and down to individually excavate a natural ground therewith. A liner 14 is constructed for a rectangular-section drilled hole formed in this way to take the reaction of an advancing jack 13 out arranged on the outer shell of the whole shield machines 4a, 4b, 4c at the end thereof. A temporary beam 15 is mounted in the cavity of the cover 14 along a boundary between the each other neighboring shield machines to take the reaction of an advancing jacks 13 in arranged inside the outer shell.
