Document Type and Number:
Japanese Patent JP3714475
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a road expanding structure for reducing foundation work for accompanying excavation, and superior in stability.
SOLUTION: A concrete floor slab 11 is arranged on a road 1 between a mountain side slope 3 and a valley side slope 2. A retaining wall 21 is arranged on the mountain side Y of the road 1, and a pressing-down part 23 is arranged in this retaining wall 21 for pressing down a mountain side end part 11Y of the concrete floor slab 11 from above. Since the mountain side end part 11Y of the concrete floor slab 11 is pressed down by the retaining wall 21 arranged on the mountain side slope 3, even if an overhang part 14H of a road surface 14 is lengthened, the concrete floor slab 11 is stabilized.
