Abstract: The present invention relates to a drilling and grouting rod apparatus, which allows a rubber jacket to be brought into close contact with a drilled hole by rotating wings rotated when a lower portion thereof is lowered by the weigh thereof, and a method for blocking an underground water leak by using the same. When a grouting material is injected into a drilled hole, foldable wings are unfolded toward the inner circumferential surface of the drilled hole so that the outer diameter of a jacket is extended while a lifting member is lowered by the weight thereof. The jacket thus closes the space between drilled hole and a unit rod, so that the grouting material injected into the drilled hole and raised can be easily blocked and working processes can be simplified. Therefore, the drilling and grouting rod apparatus allows the outer diameter of the jacket to be extended by the foldable wings to maintain the extended outer-diameter of the jacket even when a portion of the jacket is damaged by the inner circumferential surface of the drilled hole, thereby increasing the blocking efficiency of the grouting material.
