Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of corrugated pipes, and particularly relates to a PE-HM perforated reinforced corrugated pipe. BACKGROUND

[0002] Buried pipelines need a large bearing force because they are deeply buried underground (for drainage, sewage, ventilation, etc.), and the reinforced corrugated pipe is a kind of pipe widely used in buried pipelines.

[0003] A PE-HM perforated reinforced corrugated pipe is disclosed in the Chinese utility model patent with the publication number CN219493336U, which forms an intermediate hole through the upper support rib, the lower support rib and the two side walls of the support groove, thereby releasing the bending modulus, so that the pipe has stronger tensile resistance. However, there is only one intermediate hole in the structure, and the released bending modulus is limited, so the improvement of the tensile resistance is also limited. In addition, the intermediate hole in the structure is composed of two sides blocked by the support rib, and the structure and process are relatively complex, which is not conducive to production. UTILITY MODEL CONTENT

[0004] In view of the problems existing in the prior art, the utility model provides a PE-HM perforated reinforced corrugated pipe, and specifically discloses the following technical scheme:

[0005] A PE-HM perforated reinforced corrugated pipe, comprising a corrugated pipe body, a spiral seam is formed on the corrugated pipe body, a reinforced support structure is arranged on the outer wall of the corrugated pipe body, the reinforced support structure comprises two side reinforcements, the two side reinforcements are respectively located on the two sides of the spiral seam, a joint is arranged between the two side reinforcements, an adhesive is filled in the spiral seam and the joint, an intermediate hole is arranged at the center of each side reinforcement, and a plurality of release holes are formed in the inside of each side reinforcement and located on the two sides of the joint.

[0006] Further, the release holes in the inside of each side reinforcement are uniformly arranged along the radial direction of the corrugated pipe body.

[0007] Further, the release holes in the inside of each side reinforcement are uniformly arranged along the radial direction of the corrugated pipe body.

[0008] Further, the cross section of the side reinforcement is semicircular, and the intermediate hole at the center of the side reinforcement is semicircular.

[0009] Further, the adhesive is molten glue.

[0010] Further, the two ends of the corrugated pipe body are provided with connectors.

[0011] Compared with the prior art, the utility model has the advantages that:

[0012] The utility model discloses, be located in the release hole of the inside of the side reinforcement of the joint two sides, can release bigger bending modulus, and its tensile resistance is stronger because of this.

[0013] The release hole is directly arranged in the inside of the side reinforcement and is formed together with the side reinforcement, so that the structure and the manufacturing process can be simplified, thereby being more beneficial to production. BRIEF DESCRIPTION OF DRAWINGS

[0017] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of the utility model protection.

[0018] Referring to Figures 1-2 A PE-HM perforated reinforcement bellows, comprising a bellows main body 1, the bellows main body 1 is provided with a spiral seam, the outer wall of the bellows main body 1 is provided with a reinforcement support structure, the reinforcement support structure comprises two side reinforcements 3, the two side reinforcements 3 are located on the two sides of the spiral seam, the two side reinforcements 3 are provided with a joint, the spiral seam and the joint are filled with adhesive 2, the center of the two side reinforcements 3 is provided with an intermediate hole 4, and the inside of the two side reinforcements 3 is provided with a plurality of release holes 5 on the two sides of the joint.

[0019] In the embodiment, the reinforcement support structure of the bellows main body 1 is made of PE-HM (high molecular weight high density polyethylene) material.

[0020] In the embodiment, the release holes 5 in the inside of each side reinforcement 3 are uniformly arranged along the radial direction of the bellows main body 1, so that the bending modulus can be better released, and the tensile property of the bellows is improved.

[0021] In the embodiment, the release holes 5 in the inside of the two side reinforcements 3 are symmetrically arranged along the joint.

[0022] In the embodiment, the cross section of the side reinforcing rib 3 is semi-arched, and the middle hole 4 in the center of the side reinforcing rib 3 is semi-arched. The two semi-arched side reinforcing ribs 3 can form a complete arch after splicing, and the arch structure can not only enhance the stiffness of the corrugated pipe, but also increase the outer surface area of the corrugated pipe, thereby facilitating the improvement of the pressure resistance of the corrugated pipe. The arrangement of the middle hole 4 in the center of the side reinforcing rib 3 can effectively reduce the total weight and material consumption of the corrugated pipe, thereby reducing the production cost.

[0023] In the embodiment, the PE-HM perforated reinforced corrugated pipe is made by using the hot winding process of melting, the adhesive 2 is a molten adhesive, and the molten adhesive is fixedly connected with the corrugated pipe body 1 and the side reinforcing rib 3 during the forming process, thereby sealing the spiral seam and the joint.

[0024] In the embodiment, the corrugated pipe body 1 is provided with a joint 6 at each end, which can facilitate the connection with other pipelines.

[0025] As an optimization, the reinforcing support structure continuously winds the corrugated pipe body 1, so that the external load is rapidly and completely decomposed and transmitted to the corrugated pipe body 1, thereby minimizing the impact of the external load on the corrugated pipe body 1.

[0026] The above is only a preferred embodiment of the present application, and does not limit the technical scope of the present application. Therefore, any slight modification, equivalent change and modification made according to the technical essence of the present application still belongs to the scope of the technical scheme of the present application.
