Description

Technical Field

[0001] This utility model relates to the field of underground pipeline construction technology, specifically to a pipe jacking and pipe-insertion device. Background Technology

[0002] Pipe jacking is a construction method for laying underground pipelines using minimal or no excavation techniques, and it is commonly used in water diversion projects. Pipe jacking typically uses reinforced concrete pipes. Poor installation quality of the rubber sealing rings between pipe sections can lead to poor overall pipe sealing. Therefore, it is necessary to install a separate steel pipe inside the jacking pipe as a flow channel.

[0003] The traditional method of pipe jacking involves inserting steel pipes into the pipe by adding pulleys at the bottom of the pipe. However, this method is prone to derailment and deviation during the pipe insertion process, which affects construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe-passing device for pipe jacking construction, which solves the technical problem that the traditional method of passing steel pipes through pipe jacking construction involves adding pulleys to the bottom of the steel pipe for construction, but this method is prone to derailment and deviation during the pipe-passing process, which affects the construction efficiency.

[0005] To achieve the above objectives, this application provides a pipe jacking and pipe insertion device, which includes a pipe jacking and a pipe insertion assembly, wherein the pipe insertion assembly includes a support plate, a vertical plate and an arc-shaped guide plate;

[0006] The support plate is embedded in the wall of the jacking pipe;

[0007] The support plate is connected to the vertical plate on both sides along the radial direction of the jacking pipe;

[0008] The bottom of the arc-shaped guide plate is connected to the vertical plate, and the top surface of the arc-shaped guide plate is concave.

[0009] Furthermore, the curvature of the top surface of the arc-shaped guide plate is adapted to the curvature of the outer wall of the steel pipe.

[0010] Furthermore, reinforcing ribs are welded between the bottom of the upright plate and the support plate.

[0011] Furthermore, reinforcing ribs are welded between the top of the upright plate and the arc-shaped guide plate.

[0012] Furthermore, the bottom of the support plate is welded with steel reinforcement components pre-embedded in the inner wall of the jacking pipe.

[0013] Furthermore, the steel reinforcement component is inverted U-shaped.

[0014] Furthermore, the two ends of the steel reinforcement are provided with hook portions.

[0015] Furthermore, multiple pipe-penetrating assemblies are provided inside the jacking pipe, and the multiple pipe-penetrating assemblies are arranged sequentially at intervals along the axial direction of the jacking pipe.

[0016] Furthermore, the spacing between multiple tube-insertion assemblies is 1m-2m.

[0017] By adopting the above technical solution, the pipe jacking and pipe-insertion device provided in this application has the following technical advantages compared with the prior art:

[0018] The pipe-threading assembly includes a support plate, a vertical plate, and an arc-shaped guide plate. The support plate is embedded in the wall of the jacking pipe. The vertical plates are connected to both sides of the support plate along the radial direction of the jacking pipe. The bottom of the arc-shaped guide plate is connected to the vertical plate. The top surface of the arc-shaped guide plate is concave. In application, the steel pipe is placed directly on the arc-shaped guide plate, which allows for faster and more stable pipe-threading operations, improving the speed of pipe-threading and the stability of construction.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1 and Figure 2 As shown, this application provides a pipe jacking and pipe insertion device, including a pipe jacking 1 and a pipe insertion assembly. The pipe insertion assembly includes a support plate 2, a vertical plate 3 and an arc-shaped guide plate 4.

[0027] The support plate 2 is embedded in the pipe wall of the jacking pipe 1, forming an integral structure with the jacking pipe 1, thereby improving the overall structural strength. The support plate 2 is connected to the vertical plate 3 on both sides along the radial direction of the jacking pipe 1. The bottom of the arc-shaped guide plate 4 is connected to the vertical plate 3. The top surface of the arc-shaped guide plate 4 is concave. The arc-shaped guide plate 4 serves to both support the steel pipe and guide its movement.

[0028] As a preferred implementation, the top surface curvature of the arc-shaped guide plate 4 is matched with the outer wall curvature of the steel pipe to be operated, which can ensure that the steel pipe is not prone to deviation during the pipe threading operation and improve the pipe threading efficiency.

[0029] As a preferred embodiment, a reinforcing rib 5 is welded between the bottom of the upright plate 3 and the support plate 2 to increase the structural strength between the upright plate 3 and the support plate 2.

[0030] As a preferred embodiment, a reinforcing rib 5 is welded between the top of the upright plate 3 and the arc-shaped guide plate 4 to increase the structural strength between the upright plate 3 and the arc-shaped guide plate 4.

[0031] As a preferred embodiment, the bottom of the support plate 2 is welded with a steel reinforcement 6 pre-embedded in the inner wall of the jacking pipe 1. For example, the steel reinforcement 6 is in the shape of an inverted U, and the two ends of the steel reinforcement 6 are provided with hooks 7 to increase the connection strength between the support plate 2 and the jacking pipe 1.

[0032] As a preferred embodiment, multiple pipe-passing assemblies are installed inside the jacking pipe 1, and the multiple pipe-passing assemblies are arranged sequentially at intervals along the axial direction of the jacking pipe 1.

[0033] As a preferred implementation, the spacing between multiple tube-mounted components is 1m-2m.

[0034] Compared to existing technologies, the traditional method of inserting steel pipes into the pipe during pipe jacking involves adding pulleys to the bottom of the steel pipe. However, this method has low construction efficiency, poor performance, and is prone to derailment and deviation during the insertion process. The pipe insertion device provided in this application has a simple structure, ingenious design, low manufacturing cost, low construction difficulty, and high stability, which can significantly improve the efficiency of inserting steel pipes.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
