The present invention relates to a packer for the injection of a repair solution, capable of injecting a repair solution into a crack generated in a concrete structure. More specifically, the present invention includes: an injecting member connected with a repair solution injector; and a sleeve installed in the injecting member to secure sealing force against a crack. The injecting member includes a first spiral part, a spiral forming part, a second spiral part, an expansion inducing part, a third spiral part, and a flattening part, which are sequentially placed. If the injecting member is tightened by including a sloped surface in the second spiral part, the sleeve is moved from the spiral forming part to the third spiral along the second spiral part to gradually increase the diameter, and thus the present invention is capable of securing sealing force against a crack and expanding the sleeve of the expansion inducing part.
본 발명은 콘크리트 구조물에 균열이 발생되는 경우 보수액을 주입하기 위하여 균열에 삽입되는 보수액 주입용 패커에 관한 것으로서, 보다 상세하게는 보수액 주입기와 연결되는 주입부재와, 상기 주입부재에 구비되어 균열과의 밀폐력을 확보하는 슬리브를 구비하되, 상기 주입부재에 제1 나선부, 나선비형성부, 제2 나선부, 팽창유도부, 제3 나선부, 평탄부를 순차적으로 구비하되, 제2 나선부에 경사면을 구비하여 주입부재를 조이면 슬리브가 나선비형성부에서 제2 나선부를 따라 제3 나선부방향으로 이동하여 직경을 점차 증가시켜 균열과의 밀착력을 확보하고 팽창유도부 부분의 슬리브가 더 팽창될 수 있는 보수액 주입용 패커에 관한 것이다.
