摘要：A borehole plug for ground stabilisation in rock consists of only a few, simple parts and can be secured in a borehole (20) in a defined manner on account of positive-locking means (4, 17). Here, a sealing sleeve (11) is radially expanded in a known manner. A reliable non-return valve (16) consists of a sealing tube (13). The sealing tube (13) covers radial bores (6) of the supporting body (2) provided with a passage (3). <IMAGE>
