Securing and sealing pipeline comprising individual pipes for concreting into place - involves pipe line having pipe seam in each transition area with external pipe sleeve of thermoplastic and/or elastomer material

摘要

On the outside of the sleeve and outside the transition area (19) is a labyrinth seal (25) working in conjunction with the concrete. On the sleeve inside is a pipe distance holder (22) engaging in the transition area. The pipe sleeve is formed by a strip-shaped profile(15) with high elasticity in a peripheral direction, which in the transition area has an elastic expansion hose (23) in the longitudinal direction of the pipe line (R), a labyrinth seal on the outer surface comprising anchor ribs (25) connected to the profile, and on the inner peripheral surface two stop webs(22). USE/ADVANTAGE - A device for securing and sealing a pipeline in the expansion seam area, the formation of which is simple with no tendency towards constructional errors.
