Ultraviolet curing pipeline repair lining hose and winding type production process thereof

Abstract

The invention relates to the field of trenchless pipeline repair, discloses an ultraviolet curing pipeline repair lining hose and a winding type production process thereof, and breaks through the current situation of discontinuous production of manual lap joint and dry material manufacturing and glue injection processes at present. The process comprises the following three steps of: winding to manufacture a pipe, injecting glue in vacuum, and stacking and packaging. The first step comprises an inner film nesting unit, a winding unit and a wrapping and bonding unit. The second step comprises a vacuum unit, a glue injection unit and a rolling unit. The winding type production process has the advantages that the dry material hose is manufactured through winding, the problem that sheets at the lap joint position are prone to dislocation due to lap joint manufacturing in a traditional process is effectively solved, and the mechanical strength is easily guaranteed after curing; in cooperation with dry material winding, resin is injected in a vacuum infusion mode; and compared with traditional resin impregnation, the mode can quantitatively control the resin fiber ratio and is more uniform in impregnation. The continuous production process can greatly improve the production efficiency and reduce the application cost of raw materials, and the product is high in application strength and controllable in quality.

Description

technical field [0001] The invention relates to the field of non-excavation pipeline repair, in particular to an ultraviolet light-cured pipeline repair lining hose and a winding production process thereof. Background technique [0002] At present, with the development of urban construction in our country, urban underground pipelines have become an important infrastructure and part of the city. However, with the increase of service life, problems such as aging of underground pipelines, damage of pipe bodies, and falling off of pipe joints are becoming more and more serious. Compared with traditional excavation and laying new pipeline repair methods, trenchless pipeline repair technology has the advantages of fast construction speed, short construction period, high quality, tight fit between lining and pipeline, and small loss of flow area. . Among many trenchless pipeline repair technologies, UV curing has the advantages of real-time monitoring of the curing process, fast c...

AI Technical Summary

Problems solved by technology

The entire production process has no intermediate material transportation and storage process, which greatly improves production efficiency and reduces production costs; the dry material production part innovatively uses the winding production method, so that the hose has high mechanical properties of durable rebound after curing, effectively solving the problem. It solves the problems that the lap joint sheets are easy to dislocate due to lap joint production in the traditional production process of the hose, and the strength of the lap joint is difficult to grasp after curing; the glue injection process adopts vacuum infusion, the ratio of resin to fiber is more precise and controllable, and the vacuum infusion There is no resin exposure during the process, and the production environment is green and environmentally friendly
