Japanese Patent JP6803693
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a concrete side ditch with a slit buried when constructing a road, the side ditch being hard to be cracked and damaged, not causing concrete peeling, fall-off or crack due to small vibration and impact even when having aged, not resulting in depression of a top surface or cluttering when a vehicle travels due to a damage on the top surface, not requiring large heavy equipment for construction as with a conventional side ditch and therefore not causing a noise problem in the neighborhood, keeping a construction period relatively short, and preventing a rise in a construction cost.SOLUTION: A side ditch with a slit of the present invention has a slit provided in a longitudinal direction of the side ditch, the slit penetrating in a vertical direction from a top surface toward a space formed inside the side ditch, and the side ditch being provided with a reinforcing bar embedded inside. A planar reinforcement material is embedded between a top wall surface and the reinforcing bar of the side ditch.SELECTED DRAWING: Figure 1
