Abstract: A packer structure for grouting injects a repair liquid into a crack of a concrete structure. The packer structure includes a packer body having a flange adhered onto the crack and a central tube extending upwards from a central portion of the flange, an elastic tube having a first end connected to a first coupling portion of the central tube, a repair liquid injecting tube having a second coupling portion connected to a second end of the elastic tube and a check valve coupled to the repair liquid injecting tube and preventing the repair liquid from flowing backward; a first coupling cap having an inner circumference surface of a lower portion screwed to the central tube, and a second coupling cap having an inner circumference surface of an upper portion screwed to the repair liquid injecting tube.

Abstract: Provided is a packer structure for grouting which is used to inject a repair liquid into a crack of a concrete structure, the packer structure including: a packer body including a flange adhered onto the crack by a sealer, wherein a groove portion accommodating the sealer is formed on a lower surface of the flange, and a central tube that is a hollow tube extending upwards from a central portion of the flange, wherein a first coupling portion is formed at an upper portion of the central tube, has an external circumference that decreases upwards, and includes a first inclined surface; and an elastic tube having a first end connected to the first coupling portion, wherein the elastic tube inflates and deflates elastically, a repair liquid is contained in the elastic tube while the elastic tube inflates, and the repair liquid is injected into the crack by a deflation force; a repair liquid injecting tube including a second coupling portion connected to a second end of the elastic tube 20, having an external circ
