Abstract

The invention discloses a water supply and drainage pipeline with a glass fiber reinforced plastics lining and a manufacture method thereof. The water supply and drainage pipeline comprises a glass fiber reinforced plastics wear-resistant layer; a glass fiber reinforced plastics structure reinforcement layer is arranged on the outer surface of the glass fiber reinforced plastics wear-resistant layer; a threaded-type glass fiber reinforced plastics reinforcement rib layer is arranged out of the glass fiber reinforced plastics structure reinforcement layer; and a composite resin slurry reinforcement layer is arranged on the outer surface of the threaded-type glass fiber reinforced plastics reinforcement rib layer. The production technique and the structure of the water supply and drainage pipeline are reasonable; a novel layered structure and the novel layered technique are adopted; corrosion is resisted; water pollution is reduced; inner wall friction resistance is small; the bearing capacity is high; collision is resisted; excavation-resistance is high; and the service life is long.

Description

Technical field: [0001] The invention relates to a glass-steel-lined water supply and drainage pipe and a manufacturing method thereof. Background technique: [0002] At present, my country's water supply and drainage pipes mainly use a few types of pipes such as concrete pipes, reinforced concrete pipes, gray cast iron pipes and steel pipes. Commonly used pipes with pipe diameters <600mm include: ductile iron pipes, gray cast iron pipes, self-stressed reinforced concrete pipes, PVC-U pipes, steel pipes, PE pipes, etc. Reinforced concrete pipes, FRP pipes, prestressed steel cylinder concrete pipes, ductile iron pipes, etc.; commonly used pipes with diameters > 1200mm include: prestressed steel cylinder concrete pipes, prestressed concrete pipes, FRP pipes, and steel pipes. When the material of the water supply and drainage pipeline is prestressed steel cylinder concrete pipe, prestressed concrete pipe, cast iron pipe and steel pipe, under long-term operating condition...
