    摘要: The components forming the layers of a composite pipe are successively introduced into a rotary drum (1). Initially, a plastic reinforcing layer (8), including a fibre reinforcement, is introduced into the drum, the ends of the drum (1) being bounded by rings. A concrete core layer (16) is then introduced and the length of the core layer (16) is shortened relative to that of the drum (1) by shaping rings fixed to the drum ends. The shaping rings are then replaced by other shaping rings (20, 21) so that, on either side of the core layer (16), two annular spaces (22, 23) are formed which are filled by a socket material (24, 25) of the same composite as the reinforcing layer (8). Thus, at one pipe end a socket end (28) is formed and at the other pipe end a spigot end (30) is formed, each such end being located within the composite pipe wall thickness. After introducing a second reinforcing layer (26), the production of the composite pipe is completed. By producing the socket connecting elements (28, 30) simultaneously with the construction of the composite pipe, a reliable and rational production of the composite pipe with its socket connecting elements (28, 30) is achieved. By shaping a shoulder (33) on to the spigot end (30), when sliding together two composite pipes, the socket end (28) is centered. Simultaneously, an annular space (34) is formed, in which can be inserted an elastic seal (35) for drip-tight sealing.
