摘要

The device for the sealing of a pipe (9) led through a brick wall (1) has a second fiber concrete pipe (4) fitted inside a first fiber concrete pipe (3) fitted in a cylindrical penetration (10) in the wall. An adhesive course (5) is introduced into the space (12) between the larger inside diameter of the first pipe and the smaller outside diameter of the second pipe and interconnects the two. A commercially available sealing element (8) is installed in the annular space (11) between the pipe and inner surface of the second fiber concrete pipe.
