TUNNEL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a tunnel structure capable of sufficiently withstanding earth pressure and further reducing cost. SOLUTION: The tunnel structure is provided with a plurality of precast concrete slabs 12 coupled to one another so as to constitute a tunnel wall body and elastic bodies 13 installed on the outer peripheral surfaces of the concrete slabs 12. The elastic body 13 can be installed on the approximately whole surface of the concrete slab 12.
