Abstract: A borehole closure includes a supply line made of plastic and having formed therein a longitudinal passage between a feed end for inlet of an impregnating fluid and a discharge end. The supply line is formed with transverse passages, each covered by a sealing ring. A non-return valve is provided to block a flow of impregnating fluid in the direction toward the feed end. The supply line is sealingly surrounded by an inflating tube to define an elongate annular chamber therebetween which is in communication with the transverse passages. A rupture assembly having a rupture disk is secured at an end surface of the discharge end of the supply line and constructed to burst when a pressure applied by the impregnating fluid exceeds a predetermined value.
