They are an important part of municipal facilities.

[0003] The water supply and drainage pipeline in the related technology usually includes multiple water supply and drainage pipes. The diameter of one end of the water supply and drainage pipe is reduced to form a connecting part, and the inner wall of the other end is provided with a step groove. When two adjacent water supply and drainage pipes need to be connected, glue is applied on the connecting part of one of the water supply and drainage pipes, and then the connecting part is inserted into the step groove of the other water supply and drainage pipe. After the glue is cured, the connection of the two adjacent water supply and drainage pipes can be achieved.

[0004] However, fixing two adjacent water supply and drainage pipes only with glue makes the connection stability between the two adjacent water supply and drainage pipes relatively poor. When the vehicle is driving on the road, the connection position of the two water supply and drainage pipes is easily stressed and there is a risk of debonding, which affects the stability of the use of the water supply and drainage pipes and needs to be improved.

[0007] In a preferred example, the utility model can be further configured as follows: an elastic sealing ring is fixedly connected to the end of the connecting portion along its circumference, and a sealing groove for the sealing ring to be inserted into is formed at the bottom of the step groove.

[0008] In a preferred example, the present invention can be further configured as follows: two sealing rings and two sealing grooves are respectively provided, and the two sealing rings and the two sealing grooves are respectively coaxial.

[0011] In a preferred example, the utility model can be further configured as follows: sealing rings are respectively provided at the connection positions of two adjacent water supply and drainage pipes, and the two ends of the sealing rings are respectively connected to the corresponding drainage pipes through a plurality of countersunk screws.

[0012] In a preferred example, the present invention can be further configured as follows: an elastic sealing pad is fixedly connected to the inner surface of the sealing ring along its circumference.
