Underground pipeline leakage point plugging device

Abstract

The utility model relates to the technical field of pipeline leakage point plugging, in particular to an underground pipeline leakage point plugging device. The underground pipeline leakage point plugging device comprises an upper pressing disc and a lower pressing disc, a sleeving hollow ring which is coaxially arranged is fixedly installed on the lower disc face of the upper pressing disc, and an inserting ring which is coaxially arranged is fixedly installed on the upper disc face of the lower pressing disc; the upper pressing disc and the lower pressing disc are each provided with an annular elastic agent storage bag, and an annular elastic air bag is installed in the portion, between the annular elastic agent storage bags, of the telescopic barrel structure. According to the plugging device for the leakage point of the underground pipeline, the plugging agent in the annular elastic agent storage bag can be leaked and jetted, so that the pipeline at the leakage position can be plugged, and the expanded annular elastic air bag can be pressed on the plugging agent plugged on the leakage point in advance; and meanwhile, the expanded annular elastic air bag can also be used for tightly pressing the leakage point, so that the leakage point blocking effect is greatly improved.
