Description

PE-HM corrugated pipe with Kong Jiajin

Technical Field

The utility model belongs to the technical field of corrugated pipes, and particularly relates to a PE-HM corrugated pipe with Kong Jiajin.

Background

Buried pipelines require a large bearing capacity because they are buried deep in the ground (for drainage, pollution discharge, ventilation, etc.), and reinforced corrugated pipes are widely used in buried pipelines.

The Chinese patent publication No. CN219493336U discloses a PE-HM corrugated pipe with Kong Jiajin, wherein a middle hole is formed through the upper supporting rib, the lower supporting rib and the side walls at two sides of the supporting groove, so that the bending modulus is released, the pipe has stronger tensile property, but only one middle hole is arranged in the structure, the released bending modulus is limited, so that the improvement of the tensile property is limited, and the middle hole in the structure is formed by plugging the supporting ribs at two sides, so that the structure and the process are complex, and the production is not facilitated.

Disclosure of utility model

Aiming at the problems in the prior art, the utility model provides a PE-HM corrugated pipe with Kong Jiajin, and specifically discloses the following technical scheme:

The utility model provides a PE-HM takes Kong Jiajin bellows, includes the bellows main part, the spiral seam has been seted up in the bellows main part, be provided with on the outer wall of bellows main part and add muscle bearing structure, it includes two sides and add the muscle to add muscle bearing structure, two the side adds the muscle and is located respectively the both sides of spiral seam, two be provided with the seam between the side adds the muscle, in the spiral seam and all fill with the adhesive in the seam, two the center that the side adds the muscle all is provided with the centre bore, the inside that two sides add the muscle is located a plurality of release hole has been seted up respectively to the both sides of seam.

Further, the release holes in each side reinforcement are uniformly distributed along the radial direction of the corrugated pipe main body.

Further, the release holes inside the two side reinforcing bars are symmetrically arranged along the joint.

Further, the cross section of the side reinforcement is semi-arch, and the middle hole in the center of the side reinforcement is semi-arch.

Furthermore, the adhesive adopts a melt adhesive.

Further, joints are arranged at two ends of the corrugated pipe main body.

Compared with the prior art, the utility model has the beneficial effects that:

In the utility model, the inside of the side reinforcing bars positioned at two sides of the joint is provided with a plurality of release holes, so that the bending modulus can be released more and the tensile property is stronger;

the release hole is directly arranged in the side reinforcement and is formed together with the side reinforcement, so that the structure and the manufacturing process can be simplified, and the production is facilitated.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, a PE-HM belt Kong Jiajin corrugated pipe comprises a corrugated pipe main body 1, a spiral seam is formed in the corrugated pipe main body 1, a reinforcement supporting structure is arranged on the outer wall of the corrugated pipe main body 1, the reinforcement supporting structure comprises two side reinforcement ribs 3, the two side reinforcement ribs 3 are respectively located on two sides of the spiral seam, a seam is formed between the two side reinforcement ribs 3, adhesive 2 is filled in the spiral seam and the seam, middle holes 4 are formed in the centers of the two side reinforcement ribs 3, and a plurality of release holes 5 are formed in the two sides of the seam, which are located inside the two side reinforcement ribs 3.

In this embodiment, the reinforced support structure of the bellows body 1 is made of PE-HM (high molecular weight high density polyethylene) material.

In this embodiment, the release holes 5 inside each side reinforcement 3 are uniformly distributed along the radial direction of the corrugated tube main body 1, so that the bending modulus can be better released, and the tensile property of the corrugated tube is improved.

In this embodiment, the release holes 5 inside the two side ribs 3 are symmetrically arranged along the seam.

In this embodiment, the cross section of the side reinforcement 3 is semi-arch, and the middle hole 4 in the center of the side reinforcement 3 is semi-arch. The two semi-arched side reinforcing ribs 3 can form a finished arch after being spliced, and the arched structure not only can strengthen the rigidity of the corrugated pipe, but also can enlarge the outer surface area of the corrugated pipe, thereby being beneficial to improving the compression resistance of the corrugated pipe. The arrangement of the middle hole 4 in the center of the side reinforcement 3 can effectively reduce the total weight and consumable materials of the corrugated pipe, thereby reducing the production cost.

In this embodiment, the PE-HM band Kong Jiajin corrugated pipe is manufactured by a hot winding process, the adhesive 2 is a melt adhesive, and the melt adhesive forming process is fixedly connected with the corrugated pipe body 1 and the side reinforcing ribs 3, so that the spiral seam and the seam are sealed.

In this embodiment, the two ends of the bellows body 1 are provided with the connectors 6, which can facilitate connection with other pipelines.

As an optimization, the reinforced support structure continuously winds the corrugated pipe main body 1, so that the external load is rapidly and thoroughly decomposed and transferred to the corrugated pipe main body 1, and the impact of the external load on the corrugated pipe main body 1 is reduced to the greatest extent.

The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the technical scope of the present utility model, so any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical principles of the present utility model still fall within the scope of the technical solutions of the present utility model.
