[0003] With social development and the continuous expansion of engineering construction scale, the performance requirements for double-wall corrugated pipes are also increasing. However, traditional double-wall corrugated pipes have many defects.

[0004] In terms of pressure resistance, it is not good. When faced with greater external pressure, especially when buried deep underground or squeezed by heavy objects, the pipeline is prone to deformation and rupture, which affects its service life and transportation effect.

[0005] Therefore, a reinforced double-wall corrugated pipe is proposed to solve the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a reinforced double-wall corrugated pipe, which aims to improve the problem that the existing double-wall corrugated pipe has poor pressure resistance, which makes it easy to be damaged and deformed when facing high pressure, thus affecting the conveying effect.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a reinforced double-wall corrugated pipe, comprising a pipe body support section, one end of which is fixedly connected to a pipe body socket section, and the other end of which is fixedly connected to a pipe body insertion section. The pipe body socket section and the pipe body insertion section form a quick-installation assembly. A raised corrugated outer pipe is fixedly connected to the outer wall of the pipe body support section, and a connecting ring is fixedly connected to the outer wall of the pipe body support section.

[0008] The outer wall of the pipe body socket section is fixedly connected with reinforcing ribs, and the outer wall of the pipe body socket section is fixedly connected with a cutting and positioning strip.

[0011] As a further description of the above technical solution:

[0015] As a further description of the above technical solution:

[0016] The height of the arc-shaped bump is higher than the height of the smooth transition section.

[0017] As a further description of the above technical solution:

[0018] Multiple sets of the arc-shaped protrusions and smooth transition sections are connected in a ring shape, and the multiple sets of the arc-shaped protrusions and smooth transition sections are fixedly connected to the connecting ring.

[0019] As a further description of the above technical solution:

[0020] The arc-shaped protrusions are offset from the smooth transition section along the axial direction of the tube.

[0021] As a further description of the above technical solution:

[0022] The surface of the tube insertion section is configured with two levels of annular protrusions of different heights, with the outer diameters of the two annular protrusions at the far end of the tube support section being smaller than the outer diameters of the other annular protrusions.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a reinforced double-wall corrugated pipe, including a pipe support section 1, which is a common pipe for fluid flow. One end of the pipe support section 1 is fixedly connected to a pipe socket section 2, and the other end of the pipe support section 1 is fixedly connected to a pipe insertion section 35. The pipe socket section 2 and the pipe insertion section 35 form a quick-installation assembly, which facilitates the installation of multiple corrugated pipes. An outer pipe 4 is fixedly connected to the outer wall of the pipe support section 1, which can enhance the overall rigidity and strength of the pipe body. A connecting ring 5 is fixedly connected to the outer wall of the pipe support section 1.

[0033] Reference Figure 1 - Figure 2 The outer wall of the pipe body socket section 2 is fixedly connected with reinforcing ribs 31 for reinforcement and support, and the outer wall of the pipe body socket section 2 is fixedly connected with cutting and positioning strips 32.

[0034] Reference Figure 1 - Figure 3 The raised wave outer tube 4 includes several arc-shaped protrusions 41 and a smooth transition section 42 connecting the arc-shaped protrusions 41. The arrangement of the arc-shaped protrusions 41 and the smooth transition section 42 can save materials on the one hand, and the circumferential force is more evenly distributed and the support is stronger on the other hand.

[0035] Reference Figure 1 - Figure 3The arc-shaped protrusion 41, the smooth transition section 42, and the pipe body insertion section 35 are all hollow, which can reduce material consumption. The multiple sets of arc-shaped protrusions 41 have the same shape, and the multiple sets of smooth transition sections 42 have the same shape. The length of the arc-shaped protrusion 41 along the annular axis of the pipe body support section 1 is longer than the length of the smooth transition section 42, and the height of the arc-shaped protrusion 41 is higher than the height of the smooth transition section 42. The arc-shaped protrusion 41 and the smooth transition section 42 can increase the contact area between the pipe and the soil, improve friction, enhance the stability of the pipe during buried installation, and enhance the overall strength of the pipe.

[0036] Reference Figure 1 - Figure 3 Multiple sets of arc-shaped protrusions 41 and smooth transition sections 42 can be assembled into a ring shape. Multiple sets of arc-shaped protrusions 41 and smooth transition sections 42 are fixedly connected to the connecting ring 5. The arc-shaped protrusions 41 are staggered from the smooth transition sections 42 along the pipe body axis. The surface of the pipe body insertion section 35 is set with two levels of ring protrusions of different heights. The outer diameter of the two rings far from the pipe body support section 1 is smaller than the outer diameter of the other rings, which facilitates the installation of the rubber ring and facilitates the insertion of the pipe body support section 1 into the inner wall of the pipe body socket section 2.

[0037] Working principle: When using this device, first place multiple sets of pipe support sections 1 and pipe socket sections 2 in the excavated foundation in sequence, then install the rubber ring on the outer wall of the pipe insertion section 35, and then insert the pipe insertion section 35 into the pipe socket section 2.

[0038] In subsequent use, the outer tube 4 consists of several arc-shaped protrusions 41 and smooth transition sections 42. The arc-shaped protrusions 41 and smooth transition sections 42 save materials and make the circumferential force more evenly distributed, thus enhancing the support force. Multiple sets of arc-shaped protrusions 41 and smooth transition sections 42 are assembled into a ring and fixedly connected to the connecting ring 5. The arc-shaped protrusions 41 are staggered from the smooth transition sections 42 along the axial direction of the tube body. This structure increases the contact area between the device and the ground, improves friction, and enhances the stability of the device during use. At the same time, the arc-shaped protrusions 41, smooth transition sections 42, and tube insertion sections 35 are all hollow, which reduces material consumption while ensuring the strength of the structure. Together, they provide stable support for the tube body, making the corrugated pipe less prone to deformation when subjected to external pressure, thus ensuring smooth medium transmission.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
