Description

Technical Field

[0001] This invention relates to the field of communication pipeline technology, and in particular to a quick-assembly underground communication pipeline and its connecting components. Background Technology

[0002] Buried communication pipelines are a core component of modern communication network infrastructure. They are primarily used to physically protect underground communication cables (including optical fibers and electrical cables), preventing them from being directly exposed to the underground soil environment and suffering damage from corrosion, compression, and collisions, while ensuring stable transmission of communication signals. Widely used in various scenarios such as urban main roads, residential areas, industrial parks, and urban-rural fringe areas, they serve as the "underground lifeline" supporting the development of next-generation information technologies such as 5G communication, the Internet of Things, and big data transmission. With the continuous expansion of communication network coverage and the accelerated pace of construction, the demand for buried communication pipelines continues to grow, and their performance faces higher requirements. The underground environment is complex and diverse; changes in soil pH, humidity, and microbial activity can all cause corrosion to pipelines. Furthermore, underground construction spaces are often limited, making it difficult to deploy large equipment, and there may be situations where underground pipelines intersect and geological conditions are unstable. This necessitates that buried communication pipelines not only possess excellent corrosion resistance, pressure resistance, and sealing performance, but also be easy to install and maintain to adapt to different construction environments and needs.

[0003] However, existing underground communication pipelines still have many shortcomings in actual use, which seriously affect construction efficiency and usage effectiveness.

[0004] Firstly, the splicing efficiency is low and the positioning accuracy is insufficient. Most existing pipeline splicing methods rely on traditional flange connections or welding processes. Flange connections require aligning multiple bolt holes and tightening the bolts one by one, while welding requires specialized welding equipment and skilled workers, making the process cumbersome. In the confined space of underground environments, these operations are even more difficult, consuming significant time and manpower, and prone to positioning errors. This can lead to decreased sealing of the spliced ​​pipeline and even affect cable installation. In scenarios requiring rapid restoration of communication lines, such as emergency communication repairs, the inefficiency of traditional splicing methods often results in prolonged communication interruptions, causing substantial economic losses and social impact.

[0005] Secondly, the protective and sealing performance is insufficient to meet the requirements of underground environments. Underground environments contain large amounts of groundwater, corrosive soil components, and microorganisms. Existing pipeline connections typically use only a single sealing ring for sealing, resulting in a simple sealing structure. Over time, the sealing ring is prone to aging and deformation, allowing groundwater to seep into the pipeline, causing cables to become damp, short-circuit, and affecting communication quality. Simultaneously, the outer protective structure of the pipeline is weak, relying mostly on the strength of the pipeline material itself to withstand soil pressure and external impacts. Under complex geological conditions or when subjected to collisions with construction machinery, the pipeline is prone to deformation and rupture, failing to effectively protect the internal cables. Furthermore, the lack of an effective cable classification and storage structure inside the pipeline results in messy and disorganized cable installation, increasing the difficulty of cable pulling and causing significant inconvenience for later maintenance and cable replacement.

[0006] Third, monitoring and maintenance are inconvenient. Existing buried communication pipelines lack effective condition monitoring devices, making it impossible to monitor the stress, deformation, and corrosion levels of the pipelines in real time. When a pipeline malfunctions, it is difficult to quickly locate the fault, requiring extensive soil excavation for search and repair. This not only results in high maintenance costs but also damages surrounding roads, green spaces, and other environmental factors, impacting traffic and residents' lives. Furthermore, the pipelines lack clear and identifiable identification information, making it difficult to quickly distinguish between pipelines of different uses and on different road sections during later maintenance, further reducing maintenance efficiency. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapidly assembled underground communication pipeline and its connecting components.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A quick-assembly underground communication pipeline and connecting components include a pipeline body, a rubber protective sleeve bonded to the outer wall of the pipeline body, and an equally spaced annular reinforcing ribs on the outer wall of the rubber protective sleeve.

Through holes are opened on both sides of the first and second semi-arc buffer protective covers, and fixing bolts are inserted into the inner walls of the through holes. Fixing nuts are screwed onto the outer walls of the fixing bolts.

[0009] Preferably, the inner wall of the pipe body has equidistantly distributed limiting slots, and the inner wall of each limiting slot is slidably connected to a limiting strip. The end of the limiting strip is welded to the outer wall of the wire-passing housing, and the inner wall of the wire-passing groove is coated with a polytetrafluoroethylene coating.

[0010] Preferably, four equally spaced fiber optic grating sensors are installed in a ring inside the middle of the main pipe body, and a maintenance riser is installed through the middle of the main pipe body. A sealing cap is screwed to the top of the maintenance riser, and an electronic marker is installed on the inner wall of the maintenance riser.

[0011] Preferably, a first annular sealing groove is formed in the middle of one side of the outer wall of the second circular positioning boss, and a first annular sealing ring is snapped onto the inner wall of the first annular sealing groove; a second annular sealing groove is formed in the middle of one side of the outer wall of the first circular positioning boss, and a second annular sealing ring is snapped onto the inner wall of the second annular sealing groove.

[0012] Preferably, the first annular magnet has opposite magnetic properties to the second annular magnet, and the first annular magnet and the second annular magnet form a tight fit, and the first annular sealing ring and the second annular sealing ring fit together tightly.

[0013] Preferably, an annular pressure block is welded to one side of the outer wall of the second circular positioning boss, and a third annular sealing groove is opened on one side of the outer wall of the first circular positioning boss.

[0014] Preferably, the second cylindrical connecting rod is fitted with a first spring on the outer side of the inner wall of the cylindrical housing, and the connecting rod is fitted with a second spring on the outer side of the inner wall of the cylindrical housing. The stiffness coefficient of the first spring is the same as that of the second spring, and the length of the first spring is the same as that of the second spring.

[0017] Preferably, the bottom outer walls of the first and second semi-circular buffer protective covers are both welded with adjusting support rods, and the bottom outer walls of the adjusting support rods are welded with support bases. The inner walls of the first and second semi-circular buffer protective covers are both bonded with buffer pads, and a positioner is installed on one inner wall of the buffer pad.

[0018] The beneficial effects of this invention are as follows: 1. This invention has the advantages of rapid splicing and precise positioning, effectively solving the problems of low splicing efficiency and positioning deviation in the prior art. By connecting the external threads at both ends of the pipe body with the first and second circular positioning bosses, combined with the precise docking of the positioning guide rod and the positioning guide hole, and the magnetic attraction of the first and second ring magnets to assist in positioning, rapid positioning and splicing of the pipe is achieved. The entire splicing process does not require complicated professional tools and can be operated by ordinary construction personnel. The size compatibility of the positioning guide rod and the positioning guide hole ensures the splicing accuracy and avoids problems such as poor sealing caused by positioning deviation. Compared with traditional flange connection and welding process, the splicing method of this invention greatly shortens the construction time and improves the construction efficiency. It is especially suitable for emergency repairs and other scenarios that require rapid restoration of communication, reducing the losses caused by communication interruption. 2. This invention possesses excellent protective and sealing performance, effectively resisting the erosion of complex underground environments and protecting the safety of internal cables. The rubber protective sleeve on the outer wall of the pipe body provides initial buffering and scratch protection. The mesh structure formed by the annular reinforcing ribs and spiral reinforcing ribs significantly improves the pipe's compressive strength and deformation resistance, enabling it to withstand soil pressure and external impacts. The anti-corrosion coating inside the pipe effectively isolates corrosive substances and microorganisms in the soil, extending the pipe's service life. In terms of sealing performance, the fit and seal of the first and second annular sealing rings form the first line of defense, while the annular pressure block compresses the annular water-expanding pad to form the second line of defense. This double sealing structure effectively prevents the infiltration of groundwater and avoids damage to cables due to moisture. At the same time, the cable tray in the cable housing classifies and stores the cables, and the PTFE coating reduces friction during cable installation, protecting the cables and making the wiring more organized and convenient for later maintenance. 3. This invention enables real-time monitoring and convenient maintenance of pipeline status, reducing maintenance costs and improving maintenance efficiency. The fiber optic grating sensor installed in the middle of the pipeline body can monitor the pipeline's stress deformation, temperature changes, and other conditions in real time, promptly identifying potential faults. The maintenance riser provides a convenient passage for later maintenance, allowing maintenance operations to be carried out without extensive soil excavation, reducing damage to the surrounding environment. The electronic marker stores detailed pipeline information, facilitating rapid pipeline identification during maintenance, while the locator can accurately locate the pipeline's position, helping staff quickly find fault points. These designs not only reduce the manpower and material costs of maintenance but also shorten fault repair time and ensure the stable operation of the communication network.

The first circular positioning boss 15 has a second annular sealing groove 27 in the middle of one side of its outer wall, and a second annular sealing ring 28 is installed in the inner wall of the second annular sealing groove 27. The first annular magnet 21 has opposite magnetic properties to the second annular magnet 26, and the first annular magnet 21 and the second annular magnet 26 form a tight fit. The first annular sealing ring 23 and the second annular sealing ring 28 fit together tightly. An annular pressure block 24 is welded to one side of the outer wall of the second circular positioning boss 17, and a third annular sealing groove 29 is opened on one side of the outer wall of the first circular positioning boss 15. An annular water-expanding pad 30 is bonded to the inner wall of the third annular sealing groove 29, and the size of the annular pressure block 24 is adapted to the size of the third annular sealing groove 29. The second cylindrical connecting rod 36 is fitted with a first spring 39 on the outer side of the inner wall of the cylindrical housing 37, and the connecting rod 41 is fitted with a second spring 40 on the outer side of the inner wall of the cylindrical housing 37. The spring constant of the first spring 39 is the same as that of the second spring 40, and the length of the first spring 39 is the same as that of the second spring 40. The bottom diameter of the truncated cone groove 32 near the inner wall of the positioning guide rod 31 is larger than the top diameter of the truncated cone groove 32, and the top diameter of the truncated cone groove 32 is smaller than the diameter of the ball 33.

[0023] Example 2, refer to Figure 1-9A rapidly assembleable underground communication pipeline and its connecting components include a pipeline body 1. The pipeline body 1, as the core load-bearing component of the entire communication pipeline, has a structural design that directly affects the overall performance of the pipeline. A rubber protective sleeve 2 is bonded to the outer wall of the pipeline body 1. The rubber protective sleeve 2 is made of highly elastic and wear-resistant rubber material, which effectively resists friction from soil particles and minor external impacts after the pipeline is buried underground, providing initial protection and preventing the outer wall of the pipeline body 1 from directly contacting the soil and suffering wear. The outer wall of the rubber protective sleeve 2 is provided with evenly distributed annular reinforcing ribs 3. These annular reinforcing ribs 3 are uniformly arranged along the axial direction of the pipeline body 1, enhancing the radial compressive strength of the pipeline body 1 and preventing damage from soil. Deformation occurs due to lateral pressure. Evenly spaced spiral reinforcing ribs 4 are welded between the annular reinforcing ribs 3. These spiral reinforcing ribs 3 spirally encircle the outer wall of the rubber protective sleeve 2, interwoven with the annular reinforcing ribs 3 to form a mesh-like reinforcing structure. This not only further enhances the overall structural strength of the pipe body 1 but also strengthens the pipe's axial tensile strength, enabling the pipe to better adapt to the settlement and displacement of underground soil. The interior of the pipe body 1 is coated with an anti-corrosion coating 5. This coating 5 uses highly corrosion-resistant and well-adhesive anti-corrosion materials, which can isolate corrosive media such as moisture, salt, acidic or alkaline substances in the soil, preventing corrosion of the inner wall of the pipe body 1, thereby extending the service life of the pipe and protecting internal cables from corrosion. The main body of the conduit 1 is equipped with a cable housing 8, which is used to classify, store, and protect communication cables. To ensure the stability of the cable housing 8 inside the main body of the conduit 1, the inner wall of the main body of the conduit 1 has evenly distributed limiting slots 6. The limiting slots 6 extend along the axial direction of the main body of the conduit 1, and the inner wall of each limiting slot 6 is slidably fitted with a limiting strip 7. The end of the limiting strip 7 is welded to the outer wall of the cable housing 8. Through the sliding engagement of the limiting slots 6 and the limiting strip 7, the cable housing 8 can be stably installed inside the main body of the conduit 1 without radial displacement or rotation, ensuring the stability of the cable housing after installation. For stability, the cable housing 8 has evenly distributed cable grooves 9 running through it. The number of cable grooves 9 can be designed according to the actual number of cables. This allows different communication cables to be stored separately, avoiding tangling and squeezing between cables, reducing signal interference between cables, and facilitating future cable maintenance and replacement. The inner wall of the cable groove 9 is coated with a polytetrafluoroethylene (PTFE) coating. PTFE has excellent lubricity and corrosion resistance, which can reduce the friction between the cable and the inner wall of the cable groove 9 during cable insertion, making cable insertion smoother. It can also prevent the cable sheath from being damaged by friction with the inner wall of the cable groove 9, further protecting the cable. Both ends of the pipe body 1 are provided with external threads 14, through which a first circular positioning boss 15 and a second circular positioning boss 17 are respectively screwed. This screwed connection not only provides a secure connection but also facilitates disassembly and installation. When the pipe malfunctions and needs replacement or repair, the first circular positioning boss 15 or the second circular positioning boss 17 can be quickly removed from both ends of the pipe body 1, improving maintenance convenience. The outer walls of the first circular positioning boss 15 are welded with evenly distributed first fixing blocks 16, and the outer walls of the second circular positioning boss 17 are also welded with... The wall is welded with second fixing blocks 18 that are evenly distributed. The first fixing blocks 16 and the second fixing blocks 18 are evenly arranged along the circumference of the boss to ensure uniform force during connection. The middle of the second fixing block 18 is provided with a positioning guide hole 19. The middle of the first fixing block 16 is welded with a positioning guide rod 31. The inner wall size of the positioning guide hole 19 is adapted to the outer wall size of the positioning guide rod 31, so that the positioning guide rod 31 can be accurately inserted into the positioning guide hole 19 during splicing, realizing the rapid positioning of the two pipes, avoiding misalignment during splicing, and improving splicing accuracy and efficiency. The bottom two outer walls of the positioning guide rod 31 are provided with frustoconical grooves 32. A ball bearing 33 is embedded in the inner wall of the frustoconical groove 32. The bottom diameter of the frustoconical groove 32 near the inner wall of the positioning guide rod 31 is larger than the top diameter of the frustoconical groove 32, and the top diameter of the frustoconical groove 32 is smaller than the diameter of the ball bearing 33. This structural design effectively prevents the ball bearing 33 from falling out of the frustoconical groove 32, ensuring the stable installation of the ball bearing 33. A frustoconical rod body 34 is provided inside the positioning guide rod 31 on one side of the ball bearing 33. One outer wall of the frustoconical rod body 34 is welded with… A first columnar connecting rod 35 has a second columnar connecting rod 36 welded to one side of its outer wall. A columnar housing 37 is welded to the outer wall of the positioning guide rod 31, providing installation space and protection for the internal connecting rods and springs. A circular partition plate 38 is welded to one side of the outer wall of the second columnar connecting rod 36 located on the columnar housing 37. A connecting rod 41 is welded to the outer wall of the circular partition plate 38 on the side away from the second columnar connecting rod 36. An annular pressure plate 42 is welded to the outer wall of the end of the connecting rod 41. The second columnar connecting rod 36 is located on the outer wall of the inner wall of the columnar housing 37. A first spring 39 is sleeved on the side, and a second spring 40 is sleeved on the outer side of the inner wall of the cylindrical outer shell 37 on the connecting rod 41. The spring constants of the first spring 39 and the second spring 40 are the same, and the lengths of the first spring 39 and the second spring 40 are the same to ensure balanced spring force. When the positioning guide rod 31 is inserted into the positioning guide hole 19, the ball 33 is squeezed by the inner wall of the positioning guide hole 19 and moves into the conical groove 32, thereby pushing the conical rod 34 to move towards the cylindrical outer shell 37. The conical rod 34 drives the first cylindrical connecting rod. 35 and the second columnar connecting rod 36 move, the second columnar connecting rod 36 pushes the circular partition plate 38 to move, the circular partition plate 38 compresses the first spring 39 and the second spring 40, the springs generate a reaction force after being compressed, which is transmitted to the ball 33 through the circular partition plate 38, the second columnar connecting rod 36, the first columnar connecting rod 35 and the frustum rod 34, so that the ball 33 presses tightly against the inner wall of the positioning guide hole 19, which enhances the friction between the positioning guide rod 31 and the positioning guide hole 19, thereby improving the tightness of the connection between the two pipes and preventing loosening after splicing; To further enhance the tightness and sealing after splicing, a first annular groove 20 is formed on one outer wall of the second circular positioning boss 17, and a first annular magnet 21 is embedded in the inner wall of the first annular groove 20. A second annular groove 25 is formed on one outer wall of the first circular positioning boss 15, and a second annular magnet 26 is embedded in the inner wall of the second annular groove 25. The magnetic properties of the first annular magnet 21 and the second annular magnet 26 are opposite. During splicing, the two attract each other to form a tight fit, which assists in the connection between the positioning guide rod 31 and the positioning guide hole 19, making the splicing more stable. At the same time, a first annular sealing groove 22 is formed in the middle of one outer wall of the second circular positioning boss 17, and a first annular sealing ring 23 is snapped onto the inner wall of the first annular sealing groove 22. A second annular sealing groove 27 is formed in the middle of one outer wall of the first circular positioning boss 15. A second annular sealing ring 28 is installed on the inner wall. After splicing, the first annular sealing ring 23 and the second annular sealing ring 28 fit together tightly to form a first sealing effect. An annular pressure block 24 is welded to one side of the outer wall of the second circular positioning boss 17. A third annular sealing groove 29 is opened on one side of the outer wall of the first circular positioning boss 15. An annular water-swellable pad 30 is bonded to the inner wall of the third annular sealing groove 29. The size of the annular pressure block 24 is adapted to the size of the third annular sealing groove 29. When splicing, the annular pressure block 24 is inserted into the third annular sealing groove 29 and squeezes the annular water-swellable pad 30. The annular water-swellable pad 30 will expand rapidly after contact with water and fill the gap between the annular pressure block 24 and the third annular sealing groove 29 to form a second sealing line. The double sealing structure can effectively prevent groundwater and soil moisture from seeping into the inside of the pipe and protect the cable from moisture damage. The outer walls of the first circular positioning boss 15 and the second circular positioning boss 17 are respectively provided with a first semi-circular buffer protective cover 43 and a second semi-circular buffer protective cover 44. The buffer protective covers are made of high-strength, impact-resistant materials, which can provide all-round protection for the splicing parts and resist external impact and soil pressure. The inner walls of the first semi-circular buffer protective cover 43 and the second semi-circular buffer protective cover 44 are both bonded with a buffer pad 45. The buffer pad 45 is made of elastic material and has good buffering and shock absorption performance. It can absorb external impact and reduce damage to the splicing parts. The outer walls on both sides of the first semi-circular buffer protective cover 43 and the second semi-circular buffer protective cover 44 are welded with semi-cylindrical clamping tubes 46. The inner wall of the semi-cylindrical clamp 46 is bonded with an arc-shaped sealing gasket 47. The semi-cylindrical clamp 46 can fit the outer wall of the pipe body 1. The arc-shaped sealing gasket 47 enhances the sealing between the semi-cylindrical clamp 46 and the pipe body 1, preventing moisture and debris from entering the interior of the buffer protective cover. The first semi-arc buffer protective cover 43 and the second semi-arc buffer protective cover 44 have through holes 48 on both sides. The inner wall of the through hole 48 is fitted with a fixing bolt 49. The outer wall of the fixing bolt 49 is screwed with a fixing nut 50. Through the cooperation of the fixing bolt 49 and the fixing nut 50, the first semi-arc buffer protective cover 43 and the second semi-arc buffer protective cover 44 can be firmly fixed together to ensure stable protection of the splicing part. The bottom outer walls of the first semi-circular buffer protective cover 43 and the second semi-circular buffer protective cover 44 are both welded with adjustable support rods 51. The adjustable support rods 51 adopt a telescopic structure, which can adjust the height according to the actual conditions of the construction environment, ensuring the levelness and stability of the pipeline installation. The bottom outer wall of the adjustable support rods 51 is welded with a support base 52. The support base 52 adopts a large-area flat plate structure, which can increase the contact area with the ground or the bottom of the trench, improve the stability of the support, and prevent the pipeline from tilting due to soil settlement or other reasons after installation. A locator 53 is installed on one inner wall of the buffer pad layer 45. The locator 53 can obtain the position information of the pipeline in real time, which is convenient for quickly locating the specific position of the pipeline during later maintenance and reducing the search time during maintenance. Four equally spaced fiber optic grating sensors 10 are installed in a ring inside the middle of the main pipe body 1. The fiber optic grating sensors 10 can monitor the physical parameters of the main pipe body 1 in real time, such as stress deformation and temperature changes, and transmit the monitoring data to the external control system. The staff can monitor the operating status of the pipeline in real time through the control system, and promptly detect abnormalities such as pipeline deformation or damage, so as to take timely maintenance measures and prevent the fault from escalating. A maintenance riser 11 is installed through the middle of the main pipe body 1. A sealing cover 12 is screwed to the top of the maintenance riser 11. The sealing cover 12 can prevent soil, water and other debris from entering the interior of the maintenance riser 11 and play a sealing and protection role. An electronic marker 13 is installed on the inner wall of the maintenance riser 11. The electronic marker 13 stores relevant information about the pipeline, such as pipeline model, laying date, user unit, cable type, etc. During later maintenance, the staff can quickly obtain this information through a special reading device, which facilitates pipeline identification and improves maintenance efficiency. Example 3, referring to Figure 1-9 This invention relates to a rapidly assembled underground communication pipeline and its connecting components. The overall structure is basically the same as in Embodiment 1, with the main difference being that the dimensions and materials of some components have been adapted to different usage scenarios and needs. For example, in areas with high soil pressure, higher-strength materials are used to manufacture the annular reinforcing ribs 3 and spiral reinforcing ribs 4, while increasing the cross-sectional dimensions of the reinforcing ribs to further enhance the pipeline's pressure resistance. In areas with high groundwater content, materials with superior waterproof performance are used to manufacture the annular water-swellable pad 30, and its thickness is increased to ensure a sealing effect. In scenarios requiring the laying of numerous cables, the number of cable trays 9 inside the cable housing 8 is increased to meet the needs of classifying and storing multiple cables. Furthermore, the length of the pipeline body 1 can be flexibly adjusted according to the actual construction length, enabling long-distance communication cable laying through the splicing of multiple pipelines.

[0024] Working principle: During the splicing and installation process, the installation location of the pipeline is first determined according to the laying route of the communication cable and the construction environment, and a corresponding trench is excavated. The main body of the pipeline 1 is placed in the trench. By adjusting the height of the adjusting support rod 51 at the bottom of the first semi-circular buffer protective cover 43 and the second semi-circular buffer protective cover 44, the support base 52 is made to stably fit against the bottom of the trench, ensuring that the main body of the pipeline 1 is in a horizontal state, providing a stable foundation for subsequent splicing. Next, the pipeline splicing operation is carried out, aligning the first circular positioning boss 15 of one pipeline with the second circular positioning boss 17 of another pipeline. Due to the first annular... Magnet 21 has opposite magnetic properties to the second annular magnet 26. Under the attraction of magnetic force, it can quickly achieve initial positioning. At the same time, the positioning guide rod 31 on the first fixing block 16 is aligned with the positioning guide hole 19 on the second fixing block 18. The pipe is slowly pushed so that the positioning guide rod 31 is inserted into the positioning guide hole 19. During the insertion of the positioning guide rod 31, the worker manually presses the annular pressure plate 42 with both hands, so that the first cylindrical connecting rod 35 slides down, and its ball 33 can retract inward, thereby passing through the inner wall of the positioning guide hole 19 and squeezing the ball 33. The ball 33 moves into the conical groove 32. Then, because the conical rod 34 passes through the first cylindrical connecting rod 35, the ball 33 moves into the conical groove 32. Rod 35 and the second cylindrical connecting rod 36 drive the circular partition plate 38 to move. The first spring 39 and the second spring 40 interact, and the reaction force generated by the springs makes the ball 33 press tightly against the inner wall of the positioning guide hole 19, enhancing the tightness of the connection. At the same time, the annular pressure block 24 on the second circular positioning boss 17 is inserted into the third annular sealing groove 29 of the first circular positioning boss 15, squeezing the annular water-expanding pad 30. The first annular sealing ring 23 and the second annular sealing ring 28 fit together to form a double sealing structure, effectively preventing water from seeping in. Finally, the first semi-circular buffer protective cover 43 and the second semi-circular buffer protective cover 44 are wrapped around the first semi-circular buffer protective cover 43. Wrapped around the outer wall of the splicing part, the semi-cylindrical clamp 46 fits the outer wall of the main pipe body 1. The arc-shaped sealing gasket 47 further enhances the sealing performance. The fixing bolt 49 is inserted through the through hole 48 and the fixing nut 50 is screwed on to firmly fix the buffer protective cover, completing the splicing of the two pipes. Repeat the above operation to complete the continuous splicing of multiple pipes according to the laying length. After the splicing is completed, the communication cable is classified and laid through the cable tray 9 of the cable tray housing 8. The polytetrafluoroethylene coating reduces the friction during cable laying. The cooperation between the limit slot 6 and the limit insert 7 ensures the stability of the cable tray housing 8 and prevents the cable tray housing 8 from shifting during the cable laying process. During the operation monitoring and maintenance process, after the pipeline is installed, it enters normal operation. Four equidistant fiber optic grating sensors 10 (FBG-100 model) in the middle of the main pipeline 1 monitor the pipeline's stress deformation, temperature changes, and other conditions in real time. The fiber optic grating sensors 10 are connected to an external control system via a dedicated transmission line, transmitting the monitored data to the control system in real time. Staff can view the pipeline's operating parameters in real time through the control system. When the pipeline deforms due to excessive soil pressure or experiences abnormal temperature, the fiber optic grating sensors 10 will issue an alarm signal, reminding staff to conduct timely inspections. The positioner 53 (Ublox NEO-6M model GPS positioning module) on the inner wall of the buffer layer 45 obtains the pipeline's location information in real time via satellite positioning and transmits the location data to the control system, facilitating staff to determine the specific laying location of the pipeline. The electrical components on the inner wall of the maintenance riser 11 are also monitored. The sub-marker 13 (EM4305 model) stores detailed information about the pipeline. During later maintenance, staff can carry a dedicated reading device to quickly read the information in the electronic marker 13 and identify key data such as the pipeline model and laying date. When the pipeline malfunctions and needs repair, the location of the faulty pipeline can be quickly found based on the location information provided by the locator 53 and the identification information of the electronic marker 13. The sealing cover 12 at the top of the maintenance riser 11 can be opened, and the inside of the pipeline can be inspected and repaired through the maintenance riser 11 without the need for extensive soil excavation, reducing maintenance costs and minimizing the impact on the surrounding environment. If it is necessary to replace the pipeline or cable, the fixing bolts 49 and fixing nuts 50 can be removed, the buffer protective cover can be removed, and the first circular positioning boss 15 or the second circular positioning boss 17 can be disassembled through the screw connection structure to replace the pipeline or cable. After the replacement is completed, the pipeline can be reassembled and fixed to restore normal use. Regarding the wiring of electronic devices, the fiber optic grating sensor 10, the locator 53, and the electronic tag 13 all adopt a low-power design and are powered by a built-in lithium battery. The lithium battery can be replaced through the maintenance riser 11. The signal output end of the fiber optic grating sensor 10 is connected to the signal input end of the external control system through an optical fiber cable to realize the transmission of monitoring data. The locator 53 communicates with the external control system through a wireless signal to send the location information to the control system in real time. The electronic tag 13 is a passive device that is activated by the radio frequency signal of a dedicated reading device to feed back the stored information to the reading device. The reading device can interact with the control system to realize the synchronous update and management of information.
