[0026] The filter layer 3 is sleeved on the outside of the first opening and expanding drain pipe 2;

[0027] A second expanded drain pipe 4, one end of which is inserted into the other end of the first open hole expanded drain pipe 2, wherein the other end of the second expanded drain pipe 4 is also expanded;

[0028] One end of the drain straight pipe 5 is inserted into the other end of the second expanded drain pipe 4;

[0029] An inner connecting terminal 6, one end of which is inserted into the outside of the other end of the drain straight pipe 5;

[0030] One end of the external connection drain terminal 7 is inserted into the other end of the internal connection terminal 6 .

[0031] In the present embodiment, preferably, the connection areas between the first opening expanded drain pipe 2 and the second expanding drain pipe 4, and between the second expanding drain pipe 4 and the drain straight pipe 5 are provided with sealing members, which are rubber rings 9. In the connection between the first opening expanded drain pipe 2 and the second expanding drain pipe 4, when the second expanding drain pipe 4 is inserted into the first opening expanded drain pipe 2, the second expanding drain pipe 4 will squeeze the rubber ring 9, and the rubber ring 9 will be deformed at this time until the placement ring grooves 10 of the two are aligned, and then the rubber ring 9 returns to its original state and the placement ring groove 10 is sealed, so as to achieve further sealing of the connection through the rubber ring 9.
