[0024] Embodiment

[0025] Please refer to Figures 1 - 4 , this embodiment provides a jacking pipe, which includes an outer pipe 1 and a cushion pipe 2 fixed to the inner side wall of the outer pipe 1. A sleeve 5 is fixedly arranged on the inner side wall of the cushion pipe 2. The outer pipe 1, the cushion pipe 2 and the sleeve 5 are coaxially arranged; one end of the sleeve 5 extends to the outside of the outer pipe 1, and a waterproof rubber ring 3 is sleeved on the outer side wall of the sleeve 5. The waterproof rubber ring 3 is located outside the outer pipe 1, and the maximum outer diameter of the waterproof rubber ring 3 is greater than the inner diameter of the outer pipe 1.

[0026] In actual use, two jacking pipes are spliced and installed. During the installation process, the sleeve 5 of one jacking pipe is embedded into the outer pipe 1 of the other jacking pipe, thus completing the splicing and installation of the two jacking pipes. Therefore, the jacking pipes provided in this application can be spliced with each other through the process of concave-convex socket connection, reducing the welding process of pipe splicing compared with the original operation method, and more safely and efficiently completing the task of pipe splicing and laying.

[0027] Since the maximum outer diameter of the waterproof rubber ring 3 is greater than the inner diameter of the outer pipe 1, the waterproof rubber ring 3 can abut between the outer side wall of the sleeve 5 of one jacking pipe and the inner side wall of the outer pipe 1 of the other jacking pipe after the installation of the two jacking pipes, better preventing water seepage at the joint of the jacking pipes. Moreover, there is a gap left at the socket position, which is easy to handle during bending, improving the speed of pipe splicing construction operations.

[0028] The jacking pipe production process provided in this application can be corrected, cut, pre-bent, rolled into a circle, and welded using a large laser device according to the domestic raw material specifications and negative tolerances, controlling the diameter error within <5mm, and the outer surface adopts a spraying anti-rust process.

[0029] As Figures 1 - 4 shown, in some embodiments of the present utility model, the number of the waterproof rubber rings 3 is multiple and they are arranged at intervals. The arrangement of the multiple waterproof rubber rings 3 can further improve the sealing performance at the joint of the two jacking pipes.

[0030] As Figures 1 - 4 shown, in some embodiments of the present utility model, a plurality of limiting retaining rings 4 are arranged at intervals on the outer side wall of the sleeve 5, and the waterproof rubber ring 3 is located between two adjacent limiting retaining rings 4. By setting the limiting retaining rings 4 in the present utility model, the position of the waterproof rubber ring 3 can be limited by the limiting retaining rings 4, preventing the waterproof rubber ring 3 from shifting during use.

[0031] As Figures 1 - 4 shown, in some embodiments of the present utility model, a reinforcing ring 6 is provided on the inner side wall of the outer pipe 1, and the reinforcing ring 6 is coaxially arranged with the outer pipe 1. By setting the reinforcing ring 6 in the present utility model, the inner side wall of the outer pipe 1 can be supported by the reinforcing ring 6, improving the compressive performance of the outer pipe 1.

[0032] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, it is obvious that this application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this application.

[0033] Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present application is limited by the attached claims rather than the above description, so it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims in the present application. Any figure mark in the claims should not be regarded as limiting the claims involved. For those skilled in the art, the utility model can have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
