摘要：PCT No. PCT/GB95/02809 Sec. 371 Date Aug. 8, 1997 Sec. 102(e) Date Aug. 8,1997 PCT Filed Dec. 1, 1995 PCT Pub. No. WO96/18064 PCT Pub. Date Jun. 13, 1996A pipeis assembled from sections of a liner pipe formed of a moulded glass reinforced plasticsmaterial (GRP). A sleeve, also of moulded GRP, sealingly surrounds the joint between thesections. An outer pipe of polymer concrete is formed in sections on the liner pipesections to surround the latter together with the sleeve. The sections have a packerprovided between adjacent ends, and the joint is offset from the joint between the linerpipe sections. The GRP of the liner pipe can withstand high chemical concentrations intoxic sewage, the sleeve preventing seepage of sewage and being able to withstandchemical attach by any passing through the inner joint. The polymer concrete enables thepipe to withstand jacking forces, and is also resistant to chemical attack from a basicallysaline surrounding soil.
