[0002] In modern construction and municipal engineering, winding pipe as an important pipe connection mode is widely used in various drainage, water supply and cable laying engineering. However, the traditional winding pipe connection mode has some obvious problems, especially in the stability and sealing of pipe connection. Since the pipe is usually buried underground, it is affected by soil pressure, underground water and external forces, if the connection is unstable or the sealing is insufficient, it is easy to cause pipe leakage, disconnection and even damage, thereby bringing serious safety hazards and maintenance costs to the engineering.

In the construction process, due to improper operation or soil pressure and other factors, the pipe is easy to deform or shift, causing gaps in the connection, and thus affecting the sealing and stability of the pipe. In addition, the traditional pipe assembly also has certain limitations in material selection, which is often difficult to meet the use requirements in complex geological environment. SUMMARY

[0027] 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.
[0028] This utility model provides a self-locking spiral wound tube intermediate jacking tube assembly, such as... Figures 1-5 As shown, the assembly includes a jacking pipe 1. A male end 11 is installed at the upper end of the jacking pipe 1, and a female end 12 is installed at the lower end. Several upward-convex structures 2 are installed on the outer side of the male end 11. An annular groove 121 is provided on the outer wall of the female end 12, and an iron ring 3 is installed at the annular groove 121. An anti-detachment structure is installed on the inner wall of the iron ring 3. The upper and lower ends of the jacking pipe 1 are respectively connected to an external spiral pipe body. The jacking pipe 1, as the main body of the assembly, with its upper male end 11 and lower female end 12, together form the connection interface with the external spiral pipe body. The several upward-convex structures 2 on the outer side of the male end 11 can form a tight fit when connected to the external spiral pipe body, effectively increasing the friction and stability of the connection and preventing the pipe from easily detaching due to external forces. The iron ring 3 embedded in the annular groove 121 on the outer wall of the female end 12 not only provides additional support for the lower end of the jacking pipe, preventing deformation of the jacking pipe due to soil pressure and other factors during construction, but also the anti-detachment structure installed on the inner wall of the iron ring 3 further enhances the firmness of the connection. This anti-detachment structure design can effectively prevent relative sliding of the wound pipe during the connection process, ensuring the stability and reliability of the connection.
[0029] In this embodiment, the outer diameter of the male end 11 is the same as the inner diameter of the female end 12. This design ensures that the male end 11 can be tightly inserted into the female end 12, forming a stable connection. The identical diameter ensures good alignment and sealing during connection, effectively preventing loosening or leakage due to size mismatch.
[0030] Specifically, the male end 11 and the female end 12 have the same thickness. This uniform thickness design ensures a uniform distribution of stress on the pipe jacking assembly, avoiding stress concentration caused by thickness differences. This helps improve the overall pressure-bearing capacity and durability of the pipe jacking assembly.
[0031] Furthermore, the upper convex structure 2 is a hemispherical protrusion, and it is arranged at equal intervals on the outer wall of the male end 11. The hemispherical upper convex structure 2 not only increases the contact area and friction between the male end 11 and the externally wound pipe body, but also makes this reinforcement effect more uniform and stable through the equally spaced arrangement design. This helps to prevent the pipe from falling off at the connection due to external forces, and improves the stability of the connection.
[0032] Furthermore, the outer wall of the iron ring 3 is flush with the outer wall surface of the jacking pipe 1. This ensures the neatness and consistency of the entire jacking pipe assembly in appearance. At the same time, it also avoids the accumulation of soil or debris due to height differences, thereby reducing the potential risk of corrosion and damage.
[0033] Furthermore, the outer wall of the male end 11 is provided with a convex groove 111, and a clamping spring 112 is installed inside the convex groove 111. The outer end of the clamping spring 112 is connected to the upper convex structure 2. The design of the convex groove 111 and the clamping spring 112 provides additional radial support for the male end 11. When the male end 11 is connected to the external wound tube body, the clamping spring 112 will be compressed and generate a rebound force, further tightening the connection. This design enhances the tightness and self-locking capability of the connection.
[0034] Furthermore, the first type of anti-detachment structure employs a lower convex hull structure 31, which consists of several hemispherical protrusions. The design of the lower convex hull structure 31, in conjunction with the upper convex hull structure 2, constitutes a dual anti-detachment mechanism. The lower convex hull structure 31 prevents relative sliding of the externally wound tube during the connection process, thereby enhancing the stability and reliability of the connection.
[0035] Furthermore, the second type of anti-detachment structure employs a toothed ring 32 structure. The toothed ring 32 is a ring-shaped sawtooth structure, arranged at equal intervals from top to bottom. The design of the toothed ring 32 provides a more robust anti-detachment mechanism. The ring-shaped sawtooth structure increases the interlocking force and friction between the ring and the externally wound pipe body, effectively preventing the pipe from detaching at the connection point. The evenly spaced arrangement ensures the uniformity and stability of this interlocking effect.
[0036] Furthermore, the jacking pipe 1 is made of PP, PVC, or HDPE materials, while the iron ring 3 is made of stainless steel or iron, with the inside of the iron ring filled with asphalt material. The stainless steel or iron ring 3 provides additional support and corrosion resistance. The asphalt material filling the inside of the iron ring further enhances the sealing and corrosion resistance of the connection, extending the service life of the entire jacking pipe assembly.
[0037] In use, the self-locking spiral wound pipe intermediate jacking assembly of this utility model first inserts the male end 11 into one end of the outer spiral wound pipe body. The upper convex structure 2 fits tightly with the inner wall of the outer pipe body, providing initial stability and friction. When the female end 12 is connected to the other end of the outer spiral wound pipe body, the iron ring 3 provides additional support to prevent the jacking pipe from deforming due to soil pressure and other factors. At the same time, the anti-detachment structure (lower convex structure 31 or toothed ring 32) on the inner wall of the iron ring tightly engages with the outer pipe body, effectively preventing relative sliding. During the connection process between the male end 11 and the outer pipe body, the clamping spring 112 in the convex groove 111 is compressed and generates a rebound force, further tightening the connection and forming a self-locking mechanism. The asphalt material filled inside the iron ring 3 forms a sealing layer at the connection, enhancing the sealing performance and preventing corrosion.
[0038] Through the combined action of the upper convex structure 2, the clamping spring 112, and the anti-detachment structure (lower convex structure 31 or toothed ring 32), self-locking and anti-detachment at the connection are achieved, ensuring the stability and reliability of the connection. The iron ring 3 and the asphalt material on its inner side provide an additional sealing layer to prevent the intrusion of moisture and corrosive substances, extending service life. The male end 11 and the female end 12 have the same thickness, ensuring uniform stress distribution under load, improving pressure resistance and durability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
