Device for fixing and sealing a conduit through a wall opening of a building wall

摘要

The device has a hollow body (9) surrounding a conduit (3) within a wall opening with a radial distance. The hollow body is firmly connected with the conduit at two lateral ends by closing pieces (11, 12). The hollow body limits a hollow space (10) for accommodating a flowing, hardened filling substance. The hollow body comprises a rigid pipe with a wall, which comprises small holes. The holes are distributed over circumference and arranged at uniform distance from each other in the circumferential direction.
