Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-deformation technology of adhesive strips, specifically a U-shaped top iron putty type adhesive strip anti-deformation protection structure. Background Technology
[0002] In underground pipeline construction, pipe jacking technology is widely used in urban municipal engineering, transportation infrastructure, energy transmission, and other projects. Pipe jacking is a construction method that uses a pipe jacking machine to advance a pipeline to a predetermined position, offering advantages such as fast construction speed and minimal impact on the ground. However, in practical applications, pipe jacking faces enormous compressive forces during the advancement process. These pressures act on the joints between pipes, causing the sealing strips at the joints to be subjected to long-term compression, friction, and the effects of the external environment, which may lead to aging, cracking, or loss of elasticity.
[0003] During pipe jacking installation, continuous compression is required to ensure smooth pipe advancement and connection. The interface between pipes is a weak point in the pipeline system. During pipe jacking, the interface is subjected to significant axial and lateral forces, especially in areas with dense soil and hard rock layers where the pressure is concentrated. As construction progresses, the sealing strips between the pipes are continuously compressed and exposed to external substances, gradually losing their original sealing properties. This damage to the sealing strips leads to leakage at the interface, affecting the safety and stability of the overall pipeline system. No solution has yet been proposed to address these technical problems. Summary of the Invention
[0004] To address the problems in related technologies, this utility model proposes a U-shaped top iron putty-type sealing strip anti-deformation protection structure to overcome the aforementioned technical problems existing in the prior art. The purpose of this utility model is to absorb the extrusion force generated during pipe jacking, reduce the force transmitted to the interface, thereby avoiding excessive compression of the sealing strip. By reducing the risk of damage to the sealing strip, its service life can be extended, ensuring the continuous sealing effect, effectively preventing leakage of water, gas or other substances, improving the stability of the pipeline system, avoiding environmental pollution or facility damage caused by interface leakage, reducing the maintenance work required due to seal failure, lowering later maintenance costs and downtime, helping to improve the overall efficiency of pipe jacking construction, and reducing construction delays caused by sealing problems at the interface.

[0006] The buffer mechanism includes a movable plate, spring one, spring two, a reinforcing sleeve, a movable column, and a support plate. The connecting pipe has an internal cavity, and the support plate is fixedly installed within the cavity. The reinforcing sleeve passes through the support plate and is movably connected to it. Both ends of the reinforcing sleeve are connected to the support plate via spring one, and spring one is fitted onto the outer surface of the reinforcing sleeve.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Example 1
[0022] Please see Figure 1-4 This utility model proposes a technical solution for a U-shaped top iron putty-type adhesive strip anti-deformation protection structure: A U-shaped top iron putty-type adhesive strip anti-deformation protection structure includes two top pipes 1, a connecting pipe 2 between the two top pipes 1, a fixing groove 3 at both ends of the connecting pipe 2, a sealing strip 4 inside the fixing groove 3, the top pipes 1 and the connecting pipe 2 are connected by a connecting mechanism, and a buffer mechanism is also provided on the connecting pipe 2. Specifically, the connecting mechanism facilitates the connection between the top pipes 1 and the connecting pipe 2 to prevent leakage, and the buffer mechanism can protect the sealing strip 4 and extend the service life of the sealing strip 4;
[0023] The buffer mechanism includes a movable plate 5, a first spring 6, a second spring 7, a reinforcing sleeve 8, a movable column 9, and a support plate 10. The connecting pipe 2 has an internal cavity, and the support plate 10 is fixedly installed within the cavity. The reinforcing sleeve 8 passes through the support plate 10 and is movably connected to it. Both ends of the reinforcing sleeve 8 are connected to the support plate 10 via the first spring 6, which is fitted onto the outer surface of the reinforcing sleeve 8. The movable column 9 passes through the reinforcing sleeve 8 and is movably connected to it. One end of the movable column 9 extends into the fixed groove 3 and connects to one end of the movable plate 5. Plate 5 is connected to sealing strip 4. Both ends of reinforcing sleeve 8 are also connected to spring 2 7. Spring 2 7 is sleeved on the outer surface of movable column 9. Specifically, when one end of top pipe 1 is inserted into the fixing groove 3 of connecting pipe 2, it first drives movable plate 5 to move. When movable plate 5 moves, it drives movable column 9 to move. Spring 2 7 can buffer the impact force on movable column 9. At the same time, it drives reinforcing sleeve 8 to move. When reinforcing sleeve 8 moves, spring 1 6 can buffer the impact force on reinforcing sleeve 8. Through double buffering, the service life of sealing strip 4 is extended.
[0024] This invention can absorb some of the extrusion pressure generated during pipe jacking, reducing the force transmitted to the interface and thus preventing excessive compression of the sealing strip 4. By reducing the risk of damage to the sealing strip 4, the buffer mechanism can extend its service life and ensure the continuous sealing effect of the sealing strip 4, thereby improving the reliability of the entire pipeline system. The sealing strip 4 effectively prevents leakage of water, gas, or other substances, enhances the stability of the pipeline system, and avoids environmental pollution or facility damage caused by interface leakage. Since the sealing strip 4 at the interface is not easily damaged, the maintenance work required due to seal failure is reduced, lowering the later maintenance costs and downtime. The design and installation of the buffer mechanism are simple, which helps to improve the overall efficiency of pipe jacking 1 construction and reduce construction delays caused by sealing problems at the interface.

The locking seat 14 is fixedly sleeved on the outer surface of the connecting pipe 2. The inside of the locking seat 14 is provided with several placement slots. The spring 12 and the sliding plate 13 are arranged inside the placement slots. The two ends of the spring 12 are respectively connected to the placement slots and the sliding plate 13. One end of the locking block 11 is connected to the sliding plate 13, and the other end of the locking block 11 extends into the inside of the fixing slot 3.
[0027] In this embodiment, the card holder 14 serves as a support. When one end of the top tube 1 is inserted into the fixing groove 3 of the connecting tube 2, the card block 11 moves upward under the action of the spring 3 12. When the card block 11 and the card groove 16 on the top tube 1 are at the same horizontal line, the card block 11 extends into the card groove 16 under the action of the spring 3 12, so that the top tube 1 can be installed.
[0028] Please see Figure 3 As shown, the outer surface of the bottom end of the card block 11 is further designed with a sloping structure.
[0029] In this embodiment, automated insertion is achieved, reducing manual operation.

[0031] In this embodiment, the rubber post 15 effectively improves the stability of the installation.
[0032] Please see Figure 3 As shown, further, the outer surface of the jacking pipe 1 is provided with a slot 16 that matches the card block 11.
[0033] This utility model effectively improves the efficiency and stability of installation between two jacking pipes 1, increases convenience, improves construction efficiency, reduces the time required for installation, shortens the construction cycle of the entire project, reduces labor costs, reduces the occurrence of human error, improves construction quality, reduces safety hazards in complex steps, and makes the jacking pipe interface after installation more stable and has better sealing, reducing the possibility of later failures and maintenance, enhancing flexibility and adaptability, and reducing the time and cost of repair or replacement.
