However, the traditional intermediate pipe jacking assembly has many deficiencies in practical application, especially in preventing deformation and guaranteeing the sealing property of connection.

[0003] The traditional intermediate pipe jacking assembly often adopts simple straight pipe structure, lacks effective anti -deformation mechanism. After burying in soil, due to soil pressure, underground water level change and external force in the construction process, the pipe jacking is easy to deform, leads to the leakage phenomenon at the connection, seriously affects the normal operation of the pipeline system. In addition, the connection mode of traditional pipe jacking assembly is often simple, lacks reliable locking and sealing mechanism, makes the connection easy to fall off or leak, further reduces the stability of the pipeline system. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing an intermediate pipe jacking assembly of anti -deformation of expansion lock type to solve the problem that the traditional intermediate pipe jacking assembly often adopts simple straight pipe structure, lacks effective anti -deformation mechanism in the background art.

[0005] To achieve the above object, the utility model provides an intermediate pipe jacking assembly of anti -deformation of expansion lock type, including the pipe jacking, the upper end of the pipe jacking is installed with the upper port, the lower end of the pipe jacking is installed with the lower port, the outside of the upper port and the lower port is installed with the expansion lock structure, the expansion lock structure includes a plurality of arc bracing plates, the bracing plate is annular and is arranged at equal intervals, the adjacent bracing plate is connected through the soft connecting block, the inner side of the bracing plate is installed with the elastic sheet.

[0006] As preferred, the middle outer wall of the pipe jacking is installed with a ring of limit convex ring.

[0007] As preferred, the upper port and the lower port are both circular ring structure, and the thickness is same.

[0008] As preferred, the inner wall of the bracing plate is provided with recess, the elastic sheet is arc structure, the convex surface is butted on the recess inner wall, and the concave surface is butted on the outer wall of the pipe body.

[0009] As preferred, the outer wall of the bracing plate is inclined plane structure, so that the expansion lock structure as a whole forms a circular boss structure, and the diameter of the expansion lock structure gradually increases from the upper end to the lower end.

[0010] Preferably, the spring pieces are arranged in a ring-shaped manner with equal intervals.

[0011] Preferably, the inner wall of the groove is a planar structure, and the middle portion of the outer wall of the elastic piece contacts the inner wall of the groove.

[0012] Preferably, the soft connection block is an arc-shaped silicone structure with telescopic function.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This expansion-locking, anti-deformation intermediate pipe jacking assembly features an expansion-locking structure installed on the outside of the upper and lower ports. This structure consists of several arc-shaped support plates, arranged in a circular pattern with equal spacing and connected by flexible connectors. This design allows the expansion-locking structure to evenly distribute pressure when subjected to external forces, effectively resisting soil pressure, groundwater level fluctuations, and external forces during construction, significantly enhancing the pipe's ability to prevent deformation.

[0015] The spring element in the expansion-lock mechanism is cleverly designed: its convex surface abuts the inner wall of the support plate's groove, while the concave ends abut the outer wall of the tube.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides an expansion-locking anti-deformation intermediate jacking pipe assembly, such as Figures 1-4 As shown, it includes a top pipe 1, an upper port 11 is installed at the upper end of the top pipe 1, a lower port 12 is installed at the lower end of the top pipe 1, and an expansion lock structure 2 is installed on the outer side of the upper port 11 and the lower port 12. The expansion lock structure 2 includes a plurality of arc-shaped support plates 21, which are arranged in a circular manner with equal spacing. Adjacent support plates 21 are connected by soft connecting blocks 22, and elastic pieces 231 are installed on the inner side of the support plates 21. The component is provided with an upper port 11 and a lower port 12 at the upper and lower ends of the top pipe 1, respectively, and the expansion lock structure 2 is cleverly installed on the outer side of these two ports. The expansion lock structure 2 is composed of a plurality of arc-shaped support plates 21, which are arranged in a circular manner with equal spacing. This not only enhances the overall rigidity of the structure, but also realizes flexible connection through the soft connecting blocks 22 between adjacent support plates 21, so that the expansion lock structure 2 can evenly distribute the pressure when subjected to external force, effectively avoiding the deformation of the top pipe 1.

[0027] More importantly, spring pieces 231 are installed on the inner side of the support plate. When the expansion and locking structure 2 is subjected to external force, these spring pieces 231 will fit tightly on the tube body to form a reliable sealing barrier, thereby greatly improving the sealing of the connection and effectively preventing problems such as leakage and seepage.

[0028] In this embodiment, a retaining ring 13 is installed around the central outer wall of the jacking pipe 1. This design effectively restricts the axial movement and rotation of the jacking pipe 1 in the soil, enhancing its stability during installation. Acting as a physical barrier, the retaining ring 13 resists external factors such as soil pressure and water flow, ensuring that the jacking pipe 1 maintains its correct position and orientation, thereby improving the reliability and safety of the entire pipeline system.

[0029] Specifically, both the upper port 11 and the lower port 12 are circular ring structures with identical thickness. This design not only ensures the structural strength of the ports but also ensures a more uniform and secure connection between the ports and the expansion-locking structure 2. The circular ring structure evenly distributes external forces, reducing stress concentration, thereby improving the durability and deformation resistance of the ports. Furthermore, the identical thickness ensures consistency in the loads applied to the upper and lower ports 12, avoiding uneven performance due to thickness differences.

[0030] Specifically, the inner wall of support plate 21 is provided with a groove 23. Spring clip 231 is an arc-shaped structure, with its convex surface abutting the inner wall of groove 23 and its concave ends abutting the outer wall of the tube. This design allows spring clip 231 to fit tightly against the tube when external forces act on expansion-locking structure 2, forming an effective sealing ring and significantly improving the sealing of the connection. Furthermore, the curved structure of spring clip 231 and the groove 23 enhance the stability of expansion-locking structure 2, preventing spring clip 231 from falling off or shifting.

[0031] Specifically, the outer wall of support plate 2 is sloped, forming a circular boss structure. The diameter of the expansion-locking structure 2 gradually increases from its upper end to its lower end. This design is not only aesthetically pleasing but also enhances the expansion and locking effect of the expansion-locking structure 2. When external forces act on the expansion-locking structure 2, the sloped surface more effectively converts the external forces into radial expansion forces, thereby more firmly fixing the expansion-locking structure 2 in the soil and improving the pullout resistance and stability of the jacking pipe 1.

[0032] Specifically, the spring pieces 231 are arranged in a circular pattern with equal spacing. This layout ensures uniform force distribution across the expansion-locking structure 2. Each spring piece independently absorbs a portion of the external force, and the force is transmitted to each other via the flexible connectors 22, forming a stable force transmission network. This design enhances the overall load-bearing capacity and deformation resistance of the expansion-locking structure 2.

[0033] Specifically, the inner wall of groove 23 is planar, and the middle portion of the outer wall of spring clip 231 contacts the inner wall of groove 23. This design simplifies the installation of spring clip 231 and ensures a tight fit between spring clip 231 and groove 23. Furthermore, the planar structure facilitates uniform distribution of force and stable operation of spring clip 231 under load, thereby improving the reliability and durability of the sealing ring.

[0034] Specifically, the flexible connector 22 is a curved silicone structure with telescopic functionality. This material provides both the rigidity necessary to support the expansion-locking structure 2 and the flexibility to accommodate various deformations in the piping system. The curved design matches the curved structure of the support plate 21, enhancing the stability and aesthetics of the connection. This design ensures that the expansion-locking structure 2 maintains rigidity and stability while also possessing excellent flexibility and adaptability, enabling it to cope with complex and changing soil environments and construction conditions.

[0035] It is worth noting that the pipe body is made of PP / PVC / HDPE / or plastic with basalt added to improve the bearing capacity of the top pipe 1.

[0036] When using the expansion-locking, anti-deformation intermediate jacking pipe assembly of the present invention, the jacking pipe 1 is first installed in a predetermined position. The upper and lower ends of the jacking pipe 1 are provided with an upper port 11 and a lower port 12, respectively. The outer sides of these ports are pre-installed with an expansion-locking structure 2. The expansion-locking structure 2 is composed of a plurality of arcuate support plates 21, which are arranged in a circular pattern with equal spacing and interconnected by flexible connecting blocks 22 to form a rigid yet flexible overall structure. Spring clips 231 are mounted on the inner sides of the support plates 21. These spring clips maintain a certain degree of elasticity in their initial state, ready to function when subjected to external forces.

[0037] When the jacking pipe 1 assembly is subjected to soil pressure, groundwater level fluctuations, or external forces from construction, the expansion-locking structure 2 begins to bear force. The rigidity of the curved support plate 21 and the elasticity of the flexible connector 22 evenly distribute the external force, preventing deformation of the jacking pipe 1. Simultaneously, the springs 231 on the inner side of the support plate 21 are compressed, their convex surface fitting tightly against the inner wall of the groove 23, while their concave surface abuts tightly against the outer wall of the pipe, forming an effective sealing barrier.

[0038] On the central outer wall of jacking pipe 1, a retaining ring 13 plays a key role. It restricts axial movement and rotation of jacking pipe 1 in the soil, enhancing its stability. Acting as a physical barrier, retaining the ring 13 resists external factors (such as soil pressure and water impact), ensuring that jacking pipe 1 maintains its correct position and orientation.

[0039] The outer wall of the support plate 21 is designed with a sloped surface, forming the expansion-locking structure 2 into a circular boss. When subjected to external forces, the sloped surface more effectively converts the force into radial expansion force for the expansion-locking structure. This design allows the expansion-locking structure to be more firmly fixed in the soil, improving the pullout resistance and stability of the jacking pipe 1.

[0040] The elastic sheets 231 are arranged in a ring shape at equal intervals, ensuring the uniformity of the expansion lock structure under stress. Each elastic sheet can independently bear a part of external force and transmit force to each other through the soft connecting block 22. The inner wall of the groove 23 is a plane structure, which is in close contact with the middle part of the outer wall of the elastic sheet 231. This design simplifies the installation process of the elastic sheet and ensures the close cooperation and stable work between the elastic sheet and the groove.

[0041] The soft connecting block 22 is an arc-shaped silica gel structure with a telescopic function, which has a certain rigidity to support the expansion lock structure and good flexibility to adapt to various deformations of the pipeline system. This design enables the expansion lock structure to maintain rigidity and stability while also having good flexibility and adaptability, which can cope with complex and variable soil environments and construction conditions.
