Abstract

Cracks round a bore hole (19) are sealed while at the same time a rock bolt (20) is anchored in the bore hole by injecting a sealing material (23) through an injection nozzle. This comprises a sealing sleeve (10-14) with a through hole and a nonreturn valve device and is left in the bore hole after injection. The rock bolt (20) is inserted through the through hole of the valve nozzle and through the nonreturn valve device (16, 20). According to the invention, one sealing element of the non return valve device is formed of the rock bolt (20) and its other sealing element is formed of a sealing socket (16). This is pressed in a yielding and sealing manner against the rock bolt. The injection of the sealing material (23) is carried out through a gap (21) between the rock bolt and the sealing sleeve (10-14) and through the non return valve device (16, 20) during elastic deformation of the sealing socket (16).
