Inorganic reinforced fiberglass pipe jacking and molding process

Abstract

The invention discloses an inorganic reinforced fiberglass top pipe and forming craft, which is characterized by the following: choosing fiberglass reinforced organic resin composite material as seepage control and preserve lining; using fiberglass reinforced modified inorganic material as middle forced structure layer; using fiberglass fiber reinforced organic resin as covering layer; adopting top advanced construction method; adopting metal collar and plug with rubber ring to bell and spigot joint. The inner pressure of this pipe is 1.0MPa.

Description

technical field

[0001] The invention relates to a water delivery pipe and a molding process Background technique

[0002] At present, the pipes used in the jacking construction method for water supply and drainage, sewage treatment, etc. mainly include glass fiber reinforced thermosetting resin sand pipes, reinforced concrete prestressed pipes, etc. Plastic pipes are easy to age, become brittle, and cost high; reinforced concrete prestressed pipes have thick walls, heavy weight, high resistance during jacking construction, and difficulty in installation and transportation; glass fiber reinforced thermosetting resin sand pipes have smooth inner and outer surfaces , The resistance is small during jacking method construction, but the main raw material of the pipe is petroleum by-products, the resources are limited, and the cost is also high; the inorganic composite materials with magnesium chloride, magnesium oxide, etc. as the main materials generally have low strength, are no...
