The prior patent (publication number: CN 210830815U) discloses a lining pipe for repairing a non-excavation pipeline, which comprises the following components in sequential stacking arrangement in the radial direction: the waterproof layer, the first non-woven fabric layer, the glass fiber reinforced layer and the second non-woven fabric layer; the pipe body formed by the glass fiber reinforced layer is positioned between the pipe body formed by the first non-woven fabric layer and the pipe body formed by the second non-woven fabric layer, one surfaces of the first non-woven fabric layer and the second non-woven fabric layer are attached to the glass fiber reinforced layer between the first non-woven fabric layer and the second non-woven fabric layer, the other surface of the first non-woven fabric layer is combined with the waterproof layer, and glue is filled in gaps of the glass fiber reinforced layer, gaps of the second non-woven fabric layer and gaps between the glass fiber reinforced layer and the second non-woven fabric layer. The utility model discloses a bushing pipe accessible adhesive action fixes in the inboard of pipeline in non-excavation pipeline restoration to restore the damaged position of pipeline, its convenient to use has reduced the prosthetic construction degree of difficulty of pipeline. And simultaneously, the utility model discloses a bushing pipe intensity is higher in non-excavation pipeline restoration, has longer life.
When the prior art is used, hot water or steam needs to be introduced, so that the resin is cured at high temperature to realize repair, and the phenomenon of nonuniform local heating of a pipeline exists when the hot water or the steam is introduced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a bushing pipe in non-excavation is restoreed the corrosion-resistant application of steam curing to solve the problem that proposes in the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the trenchless repairing steam curing corrosion-resistant lining pipe comprises a lining pipe main body, wherein a spiral hose is wound on the outer side of the lining pipe main body, an input port is formed in one end of the spiral hose, and an output port is formed in the other end of the spiral hose.
In a preferred embodiment of the present invention, the outside of the spiral hose is corrugated, and the side of the spiral hose near the liner tube main body is open.
As a preferred embodiment of the present invention, the spiral hose is made of rubber.
As a preferred embodiment of the present invention, the input port is made of stainless steel
Compared with the prior art, the utility model provides a bushing pipe in corrosion-resistant application of non-excavation restoration steam solidification possesses following beneficial effect:
this bushing pipe in corrosion-resistant application of steam curing is restoreed to non-excavation, through the helical coiled tube that sets up, targets in place at the bushing pipe main part, during the fixed resin, can let in steam or hot water in the helical coiled tube, concentrate steam or hot water for steam or hot water all positions of bushing pipe main part inner wall in through, avoided prior art, directly let in steam or hot water and lead to the existence of bushing pipe local position and be heated inhomogeneous phenomenon, the result of use is splendid.

fig. 3 is a schematic view of the use state of the lining pipe in the trenchless repairing steam curing corrosion-resistant application of the utility model.
In the figure: 1. a liner tube body; 2. a spiral hose; 3. an input port; 4. and an output port.
Detailed Description
In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings for the non-excavation repair of the corrosion-resistant lining pipe in steam curing application.
As shown in fig. 1-3, the utility model provides a technical solution: trenchless repair steam solidification corrosion-resistant lining pipe used in application comprises a lining pipe main body 1, wherein a spiral hose 2 is wound on the outer side of the lining pipe main body 1, one end of the spiral hose 2 is provided with an input port 3, and the other end of the spiral hose 2 is provided with an output port 4.
In this embodiment, the outside of the flexible hose 2 is corrugated, and the side of the flexible hose 2 close to the liner pipe main body 1 is open.
In this embodiment, the spiral hose 2 is made of rubber, and the rubber provides flexibility for the spiral hose 2 on the one hand, so that the corrugated structure has a telescopic characteristic, after the lining pipe body 1 is turned outwards, the shape of the spiral hose can be changed according to the state of the lining pipe body 1 (the spiral hose 2 is located outside the lining pipe body 1, the outside of the spiral hose 2 is in a stretching state, the spiral hose 2 is located inside the lining pipe body 1, and the outside of the spiral hose 2 is in a compressing state), and meanwhile, the rubber also has heat insulation and corrosion resistance, and the heat insulation can improve the thermosetting effect and efficiency of steam or hot water on resin on the lining pipe body 1.
In this embodiment, the input port 3 is made of stainless steel.
The working principle is as follows: one end of a lining pipe main body 1 with resin soaked inside is turned over and fixed at an inlet of a pipeline to be repaired by a clamp, and then the inner wall of the lining pipe main body 1 with resin soaked is turned over to the outside by water or air pressure and is bonded with the inner wall of an old pipe;
when the lining pipe main body 1 reaches the end point, steam or hot water is introduced into the spiral hose 2 through the input port 3, and the steam or the hot water is concentrated, so that the steam or the hot water passes through all positions of the inner wall of the lining pipe main body 1, and the lining pipe main body 1 forms a layer of hard lining which is tightly attached to the inner wall of the old pipe and has the functions of corrosion prevention and seepage prevention.
It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are intended to be covered by the present invention.
