Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, and in particular to a corrugated pipe with strong pressure resistance. Background Technology

[0002] Urban underground pipelines refer to the pipelines and ancillary facilities within a city for water supply, drainage, gas, heating, electricity, communications, broadcasting and television, and industry. They are vital infrastructure and "lifelines" ensuring the operation of the city. Underground pipelines typically require high strength to prevent damage during long-term use. Corrugated pipes, with their high strength, are widely used in urban underground pipelines.

[0003] Although the bellows in the existing technology have high strength, their compressive strength is low, and they are easily damaged when subjected to high pressure.

[0004] Therefore, the existing corrugated pipes have the technical problem of low compressive strength. Summary of the Invention

[0005] This utility model provides a corrugated pipe with high compressive strength, which solves the technical problem of low compressive strength of corrugated pipes in the prior art.

[0006] Some implementation schemes for solving the above-mentioned technical problems include: A corrugated pipe with high pressure resistance, comprising a pipe body; and a pressure-resistant component, wherein the pressure-resistant component is disposed in the pipe body; The anti-compression component includes an anti-compression rib disposed within the pipe body and a support disposed within the pipe body that disperses the force to the outside of the pipe body; The tube body is provided with protrusions that form crests. The protrusions protrude from the outer surface of the tube body and are integral with the tube body. The anti-compression ribs are provided within the crests. A trough is formed between two adjacent protrusions, a portion of the support is located within the trough, and another portion of the support protrudes from the protrusion.

[0007] Preferably, each of the protrusions is provided with the anti-compression rib.

[0008] Preferably, the cross-sectional shape of the compression rib is polygonal, and the protrusion is provided with a receiving space to accommodate the compression rib.

[0009] Preferably, the two adjacent sides of the compression rib have an arc surface, and the arc surface is in surface contact with the accommodating space.

[0010] Preferably, the cross-sectional shape of the receiving space is circular, and the outer diameter of the circumscribed circle of the compression rib is equal to the diameter of the receiving space.

[0011] Preferably, the anti-compression rib is a stainless steel ring with a regular hexagonal cross-section.

[0012] Preferably, the support includes a support rib located within the trough, the support rib being in surface contact with the outer wall of the protrusion, and the support rib being completely located within the trough. The support also includes a guide plate that guides the force to the outside of the tube body, the support rib being welded to the guide plate, and the guide plate protruding from the protrusion.

[0013] Preferably, the guide plate is provided with a groove to accommodate the protrusion, and a portion of the protrusion is located within the groove.

[0014] Preferably, there are two guide plates, which are located at both ends of the support ridge, and the lower surface of the guide plate is flush with the end face of the support ridge.

[0015] Preferably, the guide plate is provided with reinforcing ribs, which are integral with the guide plate and protrude from the upper surface of the guide plate.

[0016] Compared with the prior art, the present invention has the following advantages: By incorporating anti-compression components, the pipe body achieves high bending strength, making it less prone to damage during long-term use.

[0017] By setting anti-compression ribs, the anti-compression ribs are used to improve the compressive strength of the protrusions. When the tube body is squeezed, the crests are not easily deformed, thus giving the tube body higher bending strength.

[0018] By setting up a support, with one part of the support located inside the trough and the other part outside the trough, when the pipe is buried underground, the part of the support outside the trough is embedded in the soil. When the support is subjected to force, it does not exert force on the pipe, but instead uses the protruding part of the support to guide the force to the soil. This allows the pipe to withstand a smaller force, making it less prone to damage during long-term use and effectively improving the compressive strength of the corrugated pipe.

[0028] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0029] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0030] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0031] Reference Figures 1 to 6 As shown, a corrugated pipe with high pressure resistance includes a pipe body 1; And the pressure-resistant component 2, wherein the pressure-resistant component 2 is disposed on the pipe body 1; The anti-compression component 2 includes an anti-compression rib 21 disposed inside the pipe body 1 and a support 22 disposed inside the pipe body 1 and dispersing the force to outside the pipe body 1; The tube body 1 is provided with a protrusion 11 forming a wave crest. The protrusion 11 protrudes from the outer surface of the tube body 1 and the protrusion 11 and the tube body 1 are an integral structure. The anti-compression rib 21 is provided inside the wave crest. A trough is formed between two adjacent protrusions 11, a part of the support 22 is located in the trough, and another part of the support 22 protrudes from the protrusion 11.

[0032] Corrugated pipes are typically made of plastic, and they possess high strength and good corrosion resistance.

[0033] Typically, the pressure-resistant component 2 should be able to withstand a large force. The pressure-resistant component 2 can be made of metal material so that it can withstand a greater force, thereby protecting the pipe body 1 and making the pipe body 1 less susceptible to damage.

[0034] In some embodiments, each of the protrusions 11 is provided with the anti-compression rib 21.

[0035] In practice, the anti-compression rib 21 should not be subjected to frequent forces. For example, when the force applied to the pipe body 1 is small, the strength of the protrusion 11 itself can withstand the force. In this case, the anti-compression rib 21 should not be subjected to forces to prevent fatigue failure of the anti-compression rib 21. In some embodiments, the cross-sectional shape of the anti-compression rib 21 is polygonal, and the protrusion 11 is provided with a receiving space to accommodate the anti-compression rib 21.

[0036] There is a certain gap between the accommodating space and the anti-compression rib 21. When the force applied to the protrusion 11 is small, the protrusion 11 bears the force. Only when the protrusion 11 undergoes excessive elastic deformation and the inner wall of the protrusion 11 comes into contact with the anti-compression rib 21 will the anti-compression rib bear the force.

[0037] Reference Figures 1 to 6 As shown, the anti-compression rib 21 should have a large contact area with the inner wall of the accommodating space to prevent the protrusion 11 from being damaged. In some embodiments, the anti-compression rib 21 has an arc surface 211 between two adjacent sides, and the arc surface 211 is in surface contact with the accommodating space.

[0038] In some embodiments, the cross-sectional shape of the receiving space is circular, and the circumcircle diameter of the anti-compression rib 21 is equal to the diameter of the receiving space.

[0039] In some embodiments, the anti-compression rib is a stainless steel ring with a regular hexagonal cross-sectional shape.

[0040] In some embodiments, the support 22 includes a support rib 221 located within the trough, the support rib 221 being in surface contact with the outer wall of the protrusion 11, and the support rib 221 being completely located within the trough. The support 22 also includes a guide plate 222 for guiding the force to the outside of the tube body 1, the support rib 221 being welded to the guide plate 222, and the guide plate 222 protruding from the protrusion 11.

[0041] In practice, corrugated pipes are usually buried underground. During construction, a tunnel is first excavated, then the pipe body 1 is placed in the tunnel, and then the tunnel is backfilled. The backfill height of the tunnel is flush with the lower surface of the guide plate 222 after the support 22 is installed on the pipe body 1. Then the support 22 is placed on the pipe body 1 so that the lower surface of the guide plate 222 is in contact with the backfilled soil or backfill material. Finally, the remaining soil or backfill material is backfilled again until the backfill material completely covers the corrugated pipe or meets the backfill requirements.

[0042] Since the guide plate 222 is in contact with the soil or backfill material, when the support rib 221 is subjected to force, the force is transmitted through the support rib 221 to the guide plate 222, and then from the guide plate 222 to the backfill material. This allows the pipe body 1 to withstand a smaller force, the pipe body 1 to have higher compressive strength, and the pipe body 1 to be less prone to damage.

[0043] In some embodiments, the guide plate 222 is provided with a groove 223 for receiving the protrusion 11, a portion of the protrusion 11 being located within the groove 223.

[0044] In some embodiments, there are two guide plates 222, which are located at the two ends of the support ridge 221, and the lower surface of the guide plate 222 is flush with the end face of the support ridge 221.

[0045] Typically, the overall height of the support 22 is the radius of the protrusion 11, or slightly smaller than the radius of the protrusion 11.

[0046] When the support 22 performs its main load-bearing function, the overall height of the support 22 can also be greater than the radius of the protrusion 11.

[0047] In some embodiments, the guide plate 222 is provided with a reinforcing rib 2221, the reinforcing rib 2221 and the guide plate 222 are an integral structure, and the reinforcing rib 2221 protrudes from the upper surface of the guide plate 222.

[0048] The cross-sectional shape of the reinforcing rib 2221 is rectangular. Alternatively, the cross-sectional shape of the reinforcing rib 2221 can also be polygonal.

[0049] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0050] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

[0051] When implementing the subject matter technical solution of this utility model, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter technical solution and the accompanying drawings. Obviously, these details are still within the scope of the subject matter technical solution of this utility model without departing from it.
