The utility model relates to the technical field of building drainage noise reduction through-wall pipes, and discloses a building drainage noise reduction through-wall pipe which comprises a water pipe, the surface of the water pipe is fixedly connected with a buffer pipe, the surface of the buffer pipe is fixedly connected with a damping column, the surface of the damping column is sleeved with a spring, and the surface of the spring is fixedly connected with the buffer pipe. One end of the spring is fixedly connected with a thermal insulation sleeve, the surface of the thermal insulation sleeve is sleeved with a limiting sleeve, the inner wall of the limiting sleeve is provided with a threaded groove, and the interior of the threaded groove is in threaded connection with a bolt. According to the building drainage noise reduction through-wall pipe, through the arrangement of the buffer pipe, the damping column and the spring, the impact force of water flow is buffered, so that the decibel of noise is reduce
