Description
Technical Field
[0001] This utility model relates to the field of pipe gallery connection technology, specifically, to a pipe gallery connection structure. Background Technology
[0002] A utility tunnel is an underground facility that centrally houses multiple pipelines (such as water supply, power supply, and communications). It is typically constructed of durable materials such as concrete or steel, has a large space, and can accommodate multiple pipeline systems. This facilitates centralized management, maintenance, and repair of the pipelines. Utility tunnels can effectively reduce the duplication of urban pipeline construction, improve space utilization, and also reduce damage to roads and traffic disruptions. In addition, the pipelines inside the utility tunnel are usually designed in a standardized manner, which facilitates later maintenance and replacement, thereby improving the safety and reliability of urban infrastructure.
[0003] In existing technologies, traditional pipe rack connections mainly use direct plug-in methods. While this method is simple, it has limitations. The main problem is the inability to effectively install sealing rings, resulting in poor sealing at pipe joints. With prolonged use, under the influence of pressure, temperature changes, and external environmental factors, the joints are prone to slight displacement or loosening, leading to leaks. Leaks not only cause water accumulation within the pipe rack but may also pose potential hazards to the surrounding environment, affecting the normal operation of pipelines and even causing long-term damage to urban infrastructure. The long-term accumulation of leaks can lead to more serious consequences, such as damage to power and communication pipelines, or failure of water supply and heating systems. Leaks can also cause internal rust and corrosion of pipelines, reducing their service life. Furthermore, water seepage caused by leaks can reduce the stability of the pipe rack structure and even affect the foundations of surrounding buildings. Therefore, those skilled in the art provide a pipe rack connection structure to solve the problems mentioned in the background. Utility Model Content

[0029] This pipe rack connection structure, through precise insertion and bolt connection between the first pipe rack body 101 and the second pipe rack body 201, combined with a multi-layer sealing design, ensures the high efficiency and stability of the pipeline system. The tight connection between the first insertion frame 104 and the second insertion frame 204 effectively avoids loosening caused by external pressure or temperature changes, enhancing the durability of the pipeline. The cooperation between the first socket frame 107 and the second socket frame 207 ensures the sealing performance and structural stability of the joint. In particular, the application of the expansion sealing pipe 301 can automatically adjust its shape according to changes in the internal pressure of the pipeline, ensuring a seamless connection and avoiding the leakage problems that are common in traditional joints. The design of the metal injection port 302 and the limiting ring 304 makes the maintenance of the sealing system simpler and faster. Through these efficient designs, this pipe rack connection structure greatly improves the durability and leakage resistance of the pipeline system, extends its service life, reduces maintenance costs, and adapts to the long-term stable operation requirements in complex environments.
[0030] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, a first insertion frame 104 is fixedly connected to the center near the edge of the side of the first pipe gallery body 101 away from the second pipe gallery body 201.
