Description

Fiber reinforced composite winding pipe

Technical Field

The utility model relates to a pipeline structure, concretely relates to compound winding pipe of fibre reinforcement.

Background

The drainage pipe is quite common in production and life, is widely applied to circulating, purifying and other equipment in the industries of environmental protection, chemical engineering and the like, and is mainly used for leading in or leading out liquid to a corresponding position to be reached. In practical application, the drain pipe is commonly used underground, and the use environment is severe, so that the corrosion resistance, the oxidation resistance and the ring rigidity of the pipeline are required to be ensured. In the prior art, most of pipelines are lack of protection from outside, so that the sealing performance, the ring rigidity and the like of the pipelines are affected to a great extent, and the existing requirements cannot be met.

In order to solve the technical problems, a steel wire mesh is wound outside the pipe body by some manufacturers to enhance the strength of the pipe body, and although the steel wire mesh has the advantages of good durability, high tensile strength and the like, the steel wire mesh is high in processing difficulty and manufacturing cost, the corrosion resistance of the steel wire is not well solved, and the steel wire can not be popularized and applied on a large scale. And most drainage pipe manufacturers in the market use old waste materials for production, the quality of pipeline products is difficult to ensure, the ring stiffness is low, and the problems of pipeline deformation, leakage, delamination and the like generally exist. The secondary maintenance caused by the quality problem of the pipeline in the pipeline industry not only causes the waste of a large amount of government resources, but also causes secondary pollution to the environment due to underground sewage.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a fiber reinforced composite winding pipe with good corrosion resistance, high strength and low production cost.

The utility model provides a technical scheme that its technical problem adopted is:

compound winding pipe of fiber reinforcement, including the body, the body from interior to exterior includes interior flat wall layer, hollow layer, outer flat wall layer in proper order, be equipped with the floor of multichannel "I shape" in the hollow layer, the one end top of floor is on interior flat wall layer, and the other end top is on outer flat wall layer, the parcel has the material enhancement layer on the outer flat wall layer, be equipped with the fibrous layer in the material enhancement layer.

In the present invention, the fiber layer is one or more layers.

In the present invention, the outer surface of the material reinforcing layer is provided with convex or concave lines.

In the present invention, the fiber layer is formed by vertically and horizontally interweaving a plurality of fiber strips.

In the present invention, the rib plate is spirally wound in the axial direction of the pipe body.

The utility model has the advantages that: the outer flat wall layer is wrapped with the material reinforcing layer and the fiber layer, so that the corrosion resistance and oxidation resistance of the pipe body are greatly improved, and the rigidity, the strength and the shock resistance are enhanced; meanwhile, the strength of the whole pipe body can be greatly enhanced by the I-shaped rib plate; furthermore, the material reinforcing layer and the fiber layer are simple to process, high in efficiency and low in production cost, are convenient to popularize and apply on a large scale, and are particularly suitable for large-scale application environments such as municipal engineering and the like. Furthermore, two or more fiber layers can be wound according to the requirements of the use environment so as to adapt to more complex or severe environment.

Drawings

The invention will be further explained with reference to the drawings and the embodiments below:

FIG. 1 is a schematic structural diagram according to a first embodiment;

FIG. 2 is an enlarged view of portion A of FIG. 1;

fig. 3 is a schematic structural diagram of the second embodiment.

Detailed Description

In a first embodiment, referring to fig. 1 to 2, the fiber reinforced composite winding pipe provided in this embodiment includes a pipe body, the pipe body sequentially includes an inner flat wall layer 1, a hollow layer 2, and an outer flat wall layer 3 from inside to outside, a plurality of ribs 4 in an "i" shape are provided in the hollow layer 2, the specific structure is that one rib 4 is wound around the pipe body in a spiral interval manner, one end of the rib 4 abuts against the inner flat wall layer 1, the other end abuts against the outer flat wall layer 3, the outer flat wall layer 3 is wrapped with a PE material reinforcing layer 5, and a fiber layer 6 is provided in the PE material reinforcing layer 5. In this embodiment, the fiber layer 6 is wound on the outer flat wall layer 3 and closely attached to the outer flat wall layer 3, and then the PE material is heated and softened and then laid on the fiber layer 6. The outer flat wall layer 3 may be corrugated, have the same technical effect, and is the same technical solution.

In a preferred embodiment, the fiber layer 6 is a single layer, and two or more layers may be used when strength is required. In order to enhance the surface strength, the outer surface of the PE material reinforcing layer 5 is provided with convex or concave lines. The texture is preferably wavy. Further, the fiber layer 6 is formed by longitudinally and transversely interweaving a plurality of fiber strips, preferably an alkali-free glass fiber mesh cloth, has high structural strength and low production cost, and can also adopt a medium-alkali glass fiber mesh cloth or a high-alkali glass fiber mesh cloth.

Second embodiment, referring to fig. 3, the principle and structure of the present embodiment are substantially the same as those of the first embodiment, and the difference is that: the fiber layer 6 is wrapped by the PE material, the fiber layer 6 is mixed in the PE material, and then the whole body is heated and softened and then is laid on the outer flat wall layer 3, so that the fiber layer 6 is arranged in the PE material reinforcing layer 5. The effect of this embodiment is substantially the same as that of the first embodiment, and is only different structures generated by different processing processes.

The above is only the preferred embodiment of the present invention, as long as the technical solution of the purpose of the present invention is realized by the substantially same means, all belong to the protection scope of the present invention.
