Adjustemet spacer for rehabilitation pipe position and Adjustment method using the same

The present invention relates to a spacer for adjusting a position, which inserted into a gap between an existing pipe and a rehabilitation pipe that restores or rehabilitates the existing pipe to adjust the position of the rehabilitation pipe, and a position adjustment method using the same. The present invention relates to a spacer for adjusting a rehabilitation pipe position, which is inserted into a gap between an existing pipe and a rehabilitation pipe that rehabilitates the existing pipe to adjust the position of the rehabilitation pipe with respect to the existing pipe. The spacer comprises: a first wedge-shaped member which is inclined at an angle so that an inner side thereof in an insertion direction ascends, and has a guide groove extended in an inclination direction and having teeth formed thereon at a predetermined pitch; and a second wedge-shaped member which is overlapped with the first wedge-shaped member to match inclined surfaces thereof, and has teeth engaging with those of the guide groove so that the second wedge-shaped member can move with respect to the first wedge-shaped member in the insertion direction in which the total height of the spacer increases and the movement is prohibited in a direction opposite the insertion direction. The second wedge-shaped member has a filler passage hole for passing a filler, injected into the gap between the existing pipe and the rehabilitation pipe, therethrough. Portions in which the teeth of the second wedge-shaped member are formed as an elastically deformable piece that can be elastically deformed into the filler passage hole. When the elastically deformable piece is elastically deformed into the filler passage hole, the teeth of the second wedge-shaped member and the teeth of the guide groove disengage from each other so that the second wedge-shaped member can move in the direction opposite the insertion direction. Therefore, the spacer allows the amount of displacement of the elastically deformable piece to be increased, thereby easily releasing the locking of the first and second wedge-shaped members. 본 발명은 기설관과 이 기설관을 수복 또는 갱생하는 갱생관의 틈에 삽입되어 갱생관의 위치조정을 수행하기 위한 위치 조정용 스페이서 및 이를 이용한 위치 조정방법에 관한 것이다. 본 발명은 기설관과 이 기설관을 갱생하는 갱생관과의 틈새에 삽입되어 기설관에 대한 갱생관의 위치를 조절하는 갱생관 위치 조정용 스페이서에 관한 것으로, 삽입방향의 안쪽이 높아지도록 소정 각도로 경사지고, 소정 피치로 이가 형성되어 경사방향으로 연장되는 가이드홈을 구비한 제1쐐기형부재와, 상기 제1쐐기형부재에 경사면을 맞춰 포개지고, 스페이서 전체의 높이가 높아지는 삽입방향으로는 제1쐐기형부재에 대한 이동이 가능함과 동시에 반대 방향으로는 이동이 저지되도록 상기 가이드홈의 이와 계합하는 이가 형성된 제2쐐기형부재를 구비하고, 상
