Description

Technical Field

[0001] The utility model relates to the technical field of municipal buildings, in particular to a municipal drainage pipeline. Background Art

[0002] Municipal drainage pipes refer to pipes buried under municipal roads for discharging sewage or rainwater. Municipal drainage pipes are generally divided into sewage and drainage pipes. Sewage is collected by drainage pipes, sent to sewage treatment plants, and then discharged into nearby water bodies or recycled. Rainwater runoff is collected by drainage pipes and generally discharged into nearby water bodies, such as rivers and canals. Pipes are generally arranged in multiple lines and exposed near water bodies. Depending on the rainfall, the traffic volume of drainage pipes is also different. When connecting municipal drainage pipes, two adjacent water supply pipes are usually directly connected through connectors. If no sealing structure is set at the connection, the gap between adjacent water supply pipes may easily lead to water leakage at the pipe connection, thereby affecting the quality of buildings around the pipes. For example, the Chinese patent with the authorization announcement number CN 215977592 U discloses a municipal drainage pipe. The utility model comprises a pipeline body, the outside of which is sleeved with a corrosion-resistant outer shell, a mounting cutout is provided on the top of the corrosion-resistant outer shell, and a magnetic sheet is provided at one side edge of the mounting cutout, a fixing block 1 is fixedly installed on the top of the magnetic sheet, a magnetic metal strip is provided at the other side edge of the mounting cutout, a fixing block 2 is provided on the top of the magnetic metal strip, and a corrosion-resistant outer shell is provided on the outside of the pipeline body. The corrosion-resistant outer shell adopts a detachable design, and the pipeline body and the corrosion outer shell are directly sleeved, and no sealing structure is provided at the connection. Therefore, due to the gap between adjacent supply pipes, water leakage is easily caused at the pipeline connection, thereby affecting the quality of the buildings around the pipeline.

[0003] Therefore, it is a problem worth studying to provide a municipal drainage pipe with a pipe connection groove having a sealing structure to prevent water leakage. Summary of the invention
