Description

Interior bushing pipe with additional strengthening
Technical Field
The utility model belongs to the technical field of lining pipes, and particularly relates to a lining pipe with a reinforcing structure.
Background
Many infrastructures in cities around the world were installed many years ago and now started to age and decay. For example, ageing pipes for sewage, storm water, gas, oil etc. start to leak due to cracks/damages in the walls of the pipes and in the connections between pipe sections. In the case of pipelines carrying sewage or other hazardous materials, it is unacceptable to allow leakage into the environment. Therefore, an important task for regional, state, and national governments around the world is to replace damaged pipelines with new pipelines, often using stronger, lined pipes.
The underground pipeline usually needs a lining pipe, and the prior art has the problems that: the existing lining pipe structure has lower strength.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems in the prior art, the utility model provides the lining pipe with the reinforcing structure, which has the advantages of improving the structural strength of a pipe body and bearing larger pressure and solves the problem of lower structural strength of the existing lining pipe.
The utility model is realized in such a way that the lining pipe with the reinforcing structure comprises a pipe body, wherein a spiral groove is formed in the pipe body, a lining layer is arranged in the groove, and an anti-corrosion layer is arranged on the surface of the pipe body.
Preferably, a threading wire is arranged between the groove and the inner liner layer.
Preferably, the cross section of the groove is an isosceles trapezoid with a small inner part and a large outer part.
Preferably, the inner liner layer is made of fluoroplastic.
Preferably, the anticorrosive layer is made of polyurea materials.
Preferably, the lining layer and the anticorrosive layer are covered on the surface of the pipe body and the groove in an injection molding or spraying mode.
Compared with the prior art, the utility model has the following beneficial effects:
1. according to the utility model, through the matched use of the pipe body, the groove, the lining layer, the anticorrosive layer and the threading wire, the structural strength of the pipe body can be improved, larger pressure can be borne, and the problem of lower structural strength of the existing lining pipe is solved.
2. The utility model improves the toughness of the pipe body by arranging the threading wire which is made of iron wires or copper wires.
3. According to the utility model, the isosceles trapezoid-shaped groove is arranged, so that the contact area of the lining layer can be increased, and the stability of the lining layer is improved.
4. The strength of the pipe body is improved by the inner liner layer made of the fluoroplastic.
5. The strength of the lining pipe can be further improved by the anti-corrosion layer made of the polyurea material.
6. According to the utility model, through the lining layer and the anticorrosive layer which cover the surface of the pipe body, the adhesion strength among the pipe body, the lining layer and the anticorrosive layer can be improved, and the higher strength of the lining pipe can be maintained.

Detailed Description
In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.
The structure of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 4, an inner lining pipe with a reinforcing structure according to an embodiment of the present invention includes a pipe body 1, a spiral groove 2 is formed on the pipe body 1, an inner lining layer 3 is disposed in the groove 2, and an anti-corrosion layer 4 is disposed on a surface of the pipe body 1.
Referring to fig. 2 and 4, a threading wire 5 is arranged between the groove 2 and the lining layer 3.
Adopt above-mentioned scheme: through setting up threading silk 5, threading silk 5 is made for iron wire or copper wire, improves the toughness of body 1.
Referring to fig. 3, the cross section of the groove 2 is an isosceles trapezoid with a small inside and a large outside.
Adopt above-mentioned scheme: through setting up isosceles trapezoid's recess 2, can increase inner liner 3's area of contact, improve inner liner 3's stability.
Referring to fig. 3, the inner liner 3 is made of fluoroplastic.
Adopt above-mentioned scheme: the strength of the pipe body 1 is improved through the inner liner 3 made of fluoroplastic.
Referring to fig. 4, the corrosion prevention layer 4 is made of polyurea material.
Adopt above-mentioned scheme: the strength of the lining pipe can be further improved by the anticorrosive layer 4 made of polyurea material.
Referring to fig. 4, the lining layer 3 and the corrosion-resistant layer 4 are coated on the surfaces of the pipe body 1 and the groove 2 by injection molding or spraying.
Adopt above-mentioned scheme: through lining layer 3 and anticorrosive coating 4 that cover body 1 surface, can improve the adhesive strength between body 1, lining layer 3 and anticorrosive coating 4, keep the higher intensity of interior bushing pipe.
The working principle of the utility model is as follows:
when in use, the pipe body 1 with the spiral groove 2 is made through extrusion molding or rotational molding, then the threading wire 5 is wound inside the groove 2, then the lining layer 3 is coated inside the groove 2, and finally the anticorrosive layer 4 is sprayed on the surface of the pipe body 1.
In summary, the following steps: this interior bushing pipe with additional strengthening uses through the cooperation that sets up body 1, recess 2, inner liner 3, anticorrosive coating 4 and threading silk 5, can improve the structural strength of body 1, can bear bigger pressure, has solved the lower problem of current inner liner tubular construction intensity.
