Abstract
The invention discloses a production process of a glass fiber reinforced plastic jacking pipe. The production process comprises the steps of making an inner lining, making an outer protective layer, mounting a die, making a structural layer, curing, demolding and baking, and after-treatment. In the jacking pipe produced with the production process disclosed by the invention, a larger thickness of the structural layer between the inner lining and the outer protective layer can be designed as required; if the jacking pipe is produced by adopting a general process, the requirement of structural strength can only be met by further increasing the using quantity of glass fiber long cutting yarns. According to the jacking pipe, the using quantity of the glass fiber long cutting yarns can be saved greatly while the requirement of the structural strength is met; the jacking pipe is lower in production cost and firmer in structure under the condition of the same jacking force; moreover, due to the design of the structural layer in the jacking pipe, the structural strength is higher than an ordinary jacking pipe; high-granularity quartz sand is added into the structural layer, so that the using quantity of other raw materials and resin can be saved while the effect cannot be achieved with the ordinary jacking pipe production method.
