Corrosion protection segment in sewage pipes - has anchoring outside projections embedded in concrete of large pipe

摘要

The corrosion protection lining is used especially the bottom part or invert of a sewage pipe or culvert. The segment has outward projecting surface plugs for anchoring into concrete which ensure good embedding on making large curved pipe bottom linings. The anchoring plugs are short cylinders or prismatic projections (5) or openings. These project radially relative to the convex outside surface (7) of the stable tube segment (4). These projecting plugs are arranged on a regular pattern of specified density per surface area.
