摘要

PROBLEM TO BE SOLVED: To rapidly carry out the concrete paving work for a wide area, such as airport pavement and also perform a repair work easily for a partial differential settlement, upon completion of concrete pavement.;SOLUTION: In this concrete pavement laid by arranging rectangular plate- shaped or square plate-shaped high-strength reinforced concrete precast slabs 1 on subgrade G, a support plate 12 for lifting up is embedded along the laying direction of the high strength reinforced concrete precast slab 1 inside the subgrade G and at a position corresponding to the pipe 6 for the lift up jack attaching jig provided at the precast slab 1, a support plate 12 for lift-up is embedded, a lift-up jack attaching jig 15 is installed to the pipe 6, when the high strength reinforced concrete precast slab 1 is settled, thereafter, the lift-up jack 16 is operated the reaction of the lift-up jack 16 is taken by the support slab 12 for the lift-up by operating the lift-up jack 16, and the high-strength reinforcing concrete precast slab 1 is raised.;COPYRIGHT: (C)2001,JPO
