[0002] Underground pipelines refer to pipelines buried underground, such as water supply pipelines, drainage pipelines, gas pipelines and communication pipelines. During the installation process of underground pipelines, their joints need to be installed and docked with the help of joints. Joints play an important role in the connection process of underground pipelines.

[0003] For example, announcement number CN218378182U discloses an underground pipe sealing joint, comprising a first pipe body and a second pipe body, wherein one end of the first pipe body is provided with an integrally formed extension pipe, and the inner wall of the second pipe body is provided with an integrally formed inner pipe, and one end of the first pipe body and the second pipe body are respectively provided with a first docking ring and a second docking ring, and an outer wall of one side of the first docking ring is provided with mounting holes distributed at equal distances, and an inner wall of one side of the mounting hole is provided with a through hole. In the present utility model, when the staff dock the first pipe body and the second pipe body, they only need to insert the first pipe body into the interior of the second pipe body, and then fix the first docking ring and the second docking ring together through multiple sets of fixing screws, thereby ensuring the stability of the first pipe body and the second pipe body after docking. The entire docking process does not require large equipment, which is convenient for people to operate;

[0004] However, the existing technology has the problem that although the problem of traditional bolts being prone to rust is solved, the risk of a single connecting element loosening or even falling off during long-term use still exists when the threaded connection is limited.

For example, the comparative patents listed above have this problem.

[0005] For this reason, we propose a buried pipeline anti-leakage safety protection joint to solve the above problems. Utility Model Content
