Problems solved by technology
[0004] The purpose of the present invention is to provide a polyethylene-lined hose, a manufacturing method and a method for repairing water supply pipelines, so as to solve the problems of large area, long cycle, large environmental impact, road surface excavation damage, and traffic interference in the traditional water supply pipeline repair construction. Serious problems; moreover, polyethylene-lined hose materials can be used in flexible combinations, relying on the structural strength of the old pipe for functional repair; it is also possible not to use the structural strength of the old pipe, and cooperate with other pipe materials for structural and functional repair of the old pipe

Embodiment Construction
[0032] The following examples are used to illustrate the present invention, but cannot be used to limit the protection scope of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention fall within the scope of the present invention.
[0033] Such as Figure 1~2 As shown, a polyethylene lined hose 10 includes a nylon fleece layer 11, a polyester yarn 12 and a polyethylene film 13;
[0034] The nylon fleece layer 11, the polyester yarn 12 and the polyethylene film 13 are from the inside to the outside in sequence.
[0035] Among them, the thickness of the lining hose 10 is 3 to 4 mm.
[0036] Among them, the polyethylene film 13 is made by a cast film method.
[0037] Among them, the polyester spun yarn net 12 is knitted by cross needle punching of polyester spun yarns.
[0038] Wherein, the thickness of the nylon fleece layer ...

Abstract
The invention discloses a polyethylene lining hose, a manufacturing method and a water supply pipeline repairing method, and belongs to the field of water supply pipeline repairing materials. The polyethylene lining hose comprises a nylon velvet layer, polyester threads and a polyethylene film, wherein a polyester thread net is arranged in the nylon velvet layer through needling knitting, and thepolyethylene film is coated on the nylon velvet layer of the polyester thread net through a casting film method process. The polyethylene lining hose formed by combining the nylon velvet layer, the polyester threads and the polyethylene film is adopted for repairing a water supply pipeline, an old water supply pipeline with good structural strength can be rapidly repaired, an old water supply pipeline without the structural strength can also be repaired in cooperation with other pipes, the effect the same as that of replacing a novel pipe is achieved, and the advantages of being short in construction process period, small in environmental influence, less in traffic interference, good in safety and the like are achieved.
Description
Technical field [0001] The invention relates to the field of water supply pipeline repair, in particular to a polyethylene lined hose, a manufacturing method and a water supply pipeline repair method. Background technique [0002] The water supply pipeline is an important infrastructure of the city, and it undertakes the important task of the environment, resources, life and industry needs and social development. With the rapid development of urbanization and industrialization in my country, after 15-30 years of operation of the water supply pipeline network constructed in the early stage, a large number of water supply pipelines have cracks, damages, misplaced pipe joints or corrosion in the pipes, which will give residents a living and industrial production. There is a great safety hazard. [0003] Traditional water supply pipeline repair construction has problems such as large area, long period, large environmental noise impact, road excavation damage, and serious traffic interf...
