Title:
TUNNEL EXCAVATION APPARATUS, AND TUNNEL EXCAVATION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/148871
Kind Code:
A1
Abstract:
Disclosed is a cylindrical excavation apparatus which has an annular cutter section that is driven into rotation. This cylindrical excavation apparatus is such that it is possible to transport excavated dirt in large quantities, and that the same can be easily removed even if clogging occurs. A tunnel excavation apparatus (1) for excavating a tunnel in the ground is equipped with an annular cutter section (32) which is provided at the tip in the excavation advancing direction, and the surface of which is equipped with bits for excavating the ground . The tunnel excavation apparatus (1) is also equipped with a cylindrical excavation mechanism (4) which is capable of driving the cutter section (32) into rotation; a shell body (10) which is connected to the rear of the cutter section (32), and is composed of a cylindrical outside tubular body (10C) that has an outside diameter approximately equal to the outside diameter of the cutter section (32), and a cylindrical inside tubular body (10B) that has an inside diameter larger than the inside diameter of the cutter section (32); a propulsion mechanism (9) which propels the excavation mechanism (4) in the excavation advancing direction; and an excavated soil discharge mechanism (6) which is mounted on the inner circumferential surface of the inside tubular body (10B), and comprises a spiral blade (42) that is driven into rotation together with the excavation mechanism (4).
