摘要： PROBLEM TO BE SOLVED: To enable low-cost excavation while allowing the barrel part of an excavator for excavating a tunnel widened relative to a basic circular cross section to have a simple composition. SOLUTION: The cylindrical shell of a shield body 1 capable of expansion and contraction corresponding to the shape of a tunnel is separated and composed of a fixed barrel 4 on the side of a long circular arc and a widened barrel 5 on the side of short circular arc. The fixed barrel 4 is formed with a guide surface 8a for guiding a slide member 7 installed in such a manner as to be extended from both end parts of the widened barrel 5 to the side of the fixed barrel 4. A widening jack 9 is installed so as to move the widened barrel 5 in an expansion-contraction direction orthogonal to the axial center O of the tunnel. The shape of a segment 31 assembled within the shield body 1 is taken as an approximately circular cross section having parallel planar walls 32 parallel to each other at the normal excavation and taken as an oval cross section wherein the planar walls 32 are extended at the widening excavation.

摘要： PROBLEM TO BE SOLVED: To provide a tunnel excavator having a plurality of cutter heads for drilling a different-diameter tunnel even in excavation of the tunnel with a large bore. SOLUTION: On a rotational receiving base arranged in a partition wall member arranged in the front part of a shield main body, a main cutter head 3 having six first spoke-shaped long cutter members 21 protruded radially is supported via a supporting leg body 25, and in the partition wall member, an auxiliary cutter head 4 having a pair of second cutter members 33 protruded on the both sides is supported freely rotationally behind the main cutter head 3. The supporting leg body 25 is constructed of a pair of supporting leg parts 25a arranged symmetrically to each other. When both of the cutter heads 3 and 4 are turned, the second cutter members 33 of the auxiliary cutter head 4 can be guided into a guiding space part A formed between the both supporting leg parts 25a.

摘要： PROBLEM TO BE SOLVED: To provide a construction method for a widened tunnel that can, with the use of a shield machine, excavate a tunnel body part for road building and at the same time smoothly and efficiently construct a widened part of a given width for the building of an emergency parking lane part beside the tunnel body part. SOLUTION: A shield machine with a small-diameter cutterhead 23 for excavating a widened part beside a cutterhead 13 for excavating a tunnel body part is used to excavate a tunnel body part T1 and a widened part T2 beside the tunnel body part over the overall tunnel length. In a tunnel section with only a road part built, the tunnel body part T1 is lined with a tunnel lining, and the widened part T2 covered in the tunnel lining is filled with a filling B. In a section with an emergency parking lane part beside the road part, the tunnel body part T1 and the widened part T2 are lined as a whole with a tunnel lining, and the road part and the emergency parking lane part widening from the road part are built respectively in the tunnel body part T1 and the widened part T2.
