EXPANSION JOINT REMOVING METHOD AND ROAD CUTTING METHOD

PROBLEM TO BE SOLVED: To provide an expansion joint removing method that suppresses water leakage from an expansion spacing section and that enables an expansion joint to be removed in a short amount of time without cutting of a reinforcement, and a road cutting method.SOLUTION: The formation of a weir 7b can inhibit water, which is jetted from a collision nozzle 41, from flowing into an expansion spacing section 2, restrain a noise, which is generated by water injection, from being propagated to the expansion spacing section 2, prevent the water from falling onto a store installed below a bridge 52, a parked vehicle and the like, and restrain a noise problem from being caused by the reverberation of the noise in the expansion spacing section 2.
