The utility model provides a kind of drainage pipeline connection structure as shown in Figs 1-4, including drainage pipeline 1 and connection
Pipeline 2,1 both ends of drainage pipeline are provided with connection pullover 11, and the connection pullover 11 is by riffled tube 111 and crushing block
112 compositions, the crushing block 112 are set to the bottom of riffled tube 111, and the both ends of the connecting pipe 2 are provided with external screw thread
Column 21,2 pipeline outer wall middle position of connecting pipe are equipped with bolt head 22, and the external thread column 21 is connected with pullover 11 is connect
When, external thread column 21 is threadedly coupled insertion riffled tube 111, the external thread column 21 and the close side in 111 bottom of riffled tube
Wall has dug rubber groove 211, is placed with rubber neck 212 in the rubber groove 211.
Specifically, the internal thread diameter of the riffled tube 111 is greater than the caliber of drainage pipeline 1, internal screw thread and drainpipe
1 junction of road is the bottom of riffled tube 111, and the bottom of riffled tube 111, crushing block 112 is arranged in the crushing block 112
Identical distance is kept between 1 inner wall of internal screw thread and drainage pipeline.
Specifically, the crushing block 112 is not contacted with the internal screw thread of riffled tube 111, crushing block 112 is tubular lobes knot
