摘要： A pipe is assembled from sections (10, 12) of a liner pipe formed of a moulded glass reinforced plastics material (GRP). A sleeve (14), also of moulded GRP, sealingly surrounds the joint between the sections (10, 12). An outer pipe of polymer concrete is formed in sections (18, 20) on the liner pipe sections (10, 12) to surround the latter together with the sleeve (14). The sections (18, 20) have a packer (22) provided between adjacent ends, and the joint is offset from the joint between the liner pipe sections (10, 12). The GRP of the liner pipe can withstand high chemical concentrations in toxic sewage, the sleeve (14) preventing seepage of sewage and being able to withstand chemical attack by any passing through the inner joint. The polymer concrete enables the pipe to withstand jacking forces, and is also resistant to chemical attack from a basically saline surrounding soil.

摘要： A method of forming a tubular conduit comprises providing first and second ring moulds (14, 16). A plurality of generally flat wall members (12) provide inner (22) and outer (20) liners for the tubular conduit. The method comprises deforming the wall members (12) to provide tubular members (20, 22), arranging the tubular members (20, 22) to extend between the first and second ring moulds (14, 16) to define an annular space therebetween and disposing a curable material (18) in the annular space to provide a core layer between the inner and outer liners (20, 22). A tubular conduit formed by such a method is also claimed.
摘要翻译：形成管状导管的方法包括提供第一和第二环形模具（14,16）。多个大致平坦的壁构件（12）为管状导管提供内部（22）和外部（20）衬垫。该方法包括使壁构件变形以提供管状构件（20,22），使管状构件（20,22）在第一和第二环形模具（14,16）之间延伸以在其间限定环形空间，将可固化材料（18）设置在环形空间中以在内衬层（20,22）之间提供芯层。还要求保护由这种方法形成的管状导管。

摘要： A pipe (12, 14) comprising a pipe wall having an inner layer (18) to withstand internal pressure on the pipe wall. The pipe wall also includes an outer layer (20) to withstand external pressure on the pipe wall. At least one of the inner and outer layers (18, 20) comprises a reinforcing material.
摘要翻译：管道（12,14）包括具有内层（18）的管壁，以承受管壁上的内部压力。管壁还包括能够承受管壁上的外部压力的外层（20）。内层和外层（18,20）中的至少一个包括增强材料。
