Problems solved by technology

[0002] In the existing technology, pipelines such as underground water pipes and sewage pipes are generally made of PVC materials. Due to the poor antifreeze performance of this water pipe, it is easy to freeze and crack in the cold winter, causing a large area of ​​overflowing water to escape, which is a big problem for residents. Or industrial use has brought some negative effects; although some antifreeze pipelines have added some insulation measures during the construction process, due to the increase of the insulation layer, it has also brought a lot of inconvenience to the construction, increasing the difficulty of construction and construction costs

Embodiment Construction

[0011] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0012] like figure 1 As shown, the invention includes a pipeline 1, an insulation layer 2, a hard protection layer 3, a soft protection layer 4 and a rigid protection cover 5. The outside of the pipeline 1 is provided with an insulation layer 2, and the outside of the insulation layer 2 is arranged in sequence. There is a hard protective layer 3 and a soft protective layer 4, and a rigid protective sheath 5 is arranged outside the protective layer.

[0013] The material of the hard protective layer 3 is hard polyurethane.

[0014] The material of the soft protective layer 4 is but not limited to asbestos or expanded perlite.

[0015] The rigid protective cover 5 is made of fiberglass or plexiglass.

[0016] An embodiment of the present invention has been described in detail above, but the content described is only a preferred embodiment of the present inven...

Abstract

The invention provides a thermal insulation leakage-proof pipeline which comprises a pipeline body, a thermal insulation layer, a hard protection layer, a soft protection layer and a rigid protection sleeve. The thermal insulation layer is arranged on the outer side of the pipeline body. The hard protection layer and the soft protection layer are sequentially arranged outside the thermal insulation layer. The rigid protection sleeve is further arranged outside the protection layers. The thermal insulation leakage-proof pipeline has the beneficial effects that the anti-freezing performance of the pipeline body is improved, the service life period of the pipeline body is prolonged, and good waterproofness and corrosion resistance are achieved.

Description

technical field [0001] The invention belongs to the pipeline field, and in particular relates to a thermal insulation and leak-proof pipeline. Background technique [0002] In the existing technology, pipelines such as underground water pipes and sewage pipes are generally made of PVC materials. Due to the poor antifreeze performance of this water pipe, it is easy to freeze and crack in the cold winter, causing a large area of ​​overflowing water to escape, which is a big problem for residents. Or industrial use has brought some negative impacts; although some antifreeze pipelines have added some insulation measures during the construction process, due to the increase in insulation layer, it has also brought a lot of inconvenience to the construction, increasing the difficulty and cost of construction. Contents of the invention [0003] The problem to be solved by the invention is to provide a thermal insulation and leak-proof pipeline, especially by improving the antifree...
