Self-propelled segment assembly equipment and self-propelled segment assembly method

摘要

PPROBLEM TO BE SOLVED: To facilitate the centering of a segment assembling mechanism on a truck, while making the truck travel on a rail laid in an excavated tunnel. PSOLUTION: This self-propelled segment assembling equipment includes: the truck 5 which moves on the rail 4 laid in the excavated tunnel 1; a main body 8 which is supported on the truck 5, and which has the segment assembling mechanism 7 for fitting a segment 6 for tunnel lining into a predetermined position in the state of holding it; an attitude adjusting mechanism 9 which is provided between the truck 5 and the main body 8 of the segment assembling mechanism 7, and which adjusts an attitude of the main body 8 so that the axial center ca of the main body 8 can correspond to that cb of the tunnel 1; and an attitude maintaining jack 10 which is provided in the main body 8, so as to be expanded in vertical and horizontal directions and keep the main body 8 in an attitude-adjusted state by a reaction force pushing an inner surface 1a of the tunnel 1.
