Drainage pipe

The utility model discloses a drainage pipe, including soft drainage pipe soft drainage pipe intraductal be equipped with with the bearing structure that soft drainage pipe inner wall matches, the last hole that supplies the fluid passage that is equipped with of bearing structure. The intraductal bearing structure that sets up through setting up at soft drainage pipe when soft drainage pipe receives radial pressure, can show the local lifting surface area that increases soft drainage pipe to promote soft drainage pipe's cross -section compressive capacity, reduce or avoid soft drainage pipe to take place to warp, ensure soft drainage pipe's normal use. The utility model discloses a drainage pipe's simple structure, only need to put into in current soft drainage pipe the some bearing structure can, the practicality is high, simple to operate. 本实用新型公开了种排水管，包括软式排水管，在所述软式排水管的管内设有与所述软式排水管内壁匹配的支撑结构；所述支撑结构上设有供液体通过的孔隙。通过设置在软式排水管的管内设置支撑结构，当软式排水管受到径向压力时，可以显著增加软式排水管的局部受力面积，从而提升软式排水管的截面抗压能力，降低或避免软式排水管发生变形，确保软式排水管的正常使用。本
