RESIN INJECTOR FOR ANCHOR EMBEDDED IN CONCRETE SURFACE

PROBLEM TO BE SOLVED: To provide a resin injector capable of improving compensation of construction strength by sealing so as to prevent press-fitting pressure from escaping from between a nozzle of the resin injector and a base end part of an anchor pipe and by efficiently injecting a resin into a clearance between the anchor pipe and a lower hole and cracks produced around the lower hole when injecting the resin into the anchor pipe, and capable of increasing the lifetime of the anchor pipe by suppressing its corrosion.SOLUTION: A resin injector is provided with a cylindrical nozzle at it tip, with the nozzle being formed so that its diameter is smaller than the inner diameter of the anchor pipe and having a length reaching a depth nearly before a slot of the anchor pipe. A packing for sealing a gap between a base end part/collar part side of the anchor pipe and the injector is provided at a base end part of the nozzle.
