Drainage pipeline connecting structure

The utility model relates to the field of pipeline engineering, in particular to a drainage pipeline connecting structure which comprises a foundation pipe, an abutting pipe with the end used for abutting against the end of a drainage pipe is arranged in the foundation pipe, and a locking structure used for blocking a fixing circular ring on the drainage pipe is arranged on the foundation pipe. A sealing structure used for reducing a gap between the abutting pipe and the drainage pipe is further arranged at the end, close to the drainage pipe, of the abutting pipe. The connecting structure has the effects that the mounting steps of the connecting structure are simplified, and the pipelines can be quickly connected. 本申请涉及管道工程的领域，尤其是涉及一种排水管道连接结构，其包括基础管，所述基础管中设置有端部用于与排水管的端部相抵接的抵接管，所述基础管上设置有用于阻挡排水管上的固定圆环的锁定结构，所述抵接管靠近排水管的一端还设置有用于减少所述抵接管与排水管之间的缝隙的密封结构。本申请具有简化连接结构的安装步骤，可以对管道进行快速连接的效果。
