摘要
A concrete pipe (2) having an end face (6, 14) is provided with a load-distributing means, which consists of at least one load-distributing strip (5). The strip has a first portion (5') which is embedded in the concrete pipe (2), and a second portion (5') which projects essentially axially from the end face (6, 14) of the concrete pipe (2). The first portion (5') is made of a vulcanised rubber material, and the second portion (5') projecting from the end face (6, 14) of the concrete pipe (2) is made of an unvulcanised rubber material, which is externally enclosed by a layer of vulcanised rubber material. A bottom ring for a mould for casting the concrete pipe (2) is adapted to form the end face (6, 14) of the concrete pipe (2). The bottom ring has at least two slots extending in the circumferential direction of the ring and adapted to hold the rubber strips (5) during casting of the concrete pipe (2).
