The invention relates to a drainage pipe, in particular to a sound insulation and noise reduction mesopore spiral pipe. The mesopore spiral pipe comprises a pipy channel, water flow adjusting parts, a noise reduction part and a strengthening part, wherein the water flow adjusting parts are arranged on the inner wall of the pipy channel, and the noise reduction part and the strengthening part are arranged in the pipe wall of the pipy channel. The water flow adjusting parts extend from one end of the pipy channel to the other end of the pipy channel. The length direction of the water flow adjusting parts is inclined compared with the length direction of the pipy channel. The mesopore spiral pipe is characterized in that each water flow adjusting part comprises a flow guiding part and a flow carrying surface; each flow guiding part comprises a first flow guiding surface and a second flow guiding surface; each flow carrying surface comprises a cambered surface arranged between every two adjacent flow guiding parts; and the noise reduction part and the strengthening part extend from one end of the pipy channel to the other end of the pipy channel and are arranged in the circumferential direction of the pipy channel in a spaced mode.
