Abstract

The invention relates to a machining method of a water drainage pipe and a water drainage pipe. The machining method comprises the following steps that the second end of a first initial pipe is arranged on a clamp, and the first initial pipe is clamped and fixed; a chamfering machining device is arranged at the first end of the first initial pipe and carries out chamfering, and a first inner chamfer with the angle being theta is machined out; and the chamfering machining device moves in the central axis direction of the first initial pipe, and the chamfering machining device moves from one side away from the clamp to one side close to the clamp, until the first inner chamfer is machined out. The chamfering machining device comprises a driving device and a grinding disc. The driving deviceis provided with an output shaft, and the output shaft is fixedly connected with the grinding disc to drive the grinding disc to rotate. A groove is formed in the beginning of the second end of the grinding disc, and is circumferentially formed around the edge of a disc body with the central axis of the grinding disc as an axis. The shape and the size of the groove are matched with those of the first inner chamfer. The nappe phenomenon can be effectively prevented.

Description

technical field [0001] The present disclosure relates to the field of pipeline engineering, and in particular to a processing method of a drainage pipe and the drainage pipe. Background technique [0002] The existing HDPE drainage pipes have a butt-welding interface when they are connected, and there is a crimp on the inner surface and the outer surface of the pipe. And this curling will hinder the flow of water in the pipe, so that the HDPE high-density polyethylene building drainage riser will produce a water tongue phenomenon during installation, thereby affecting the flow of the building drainage riser. Contents of the invention [0003] In view of this, the present disclosure proposes a method for processing the drainpipe, which can eliminate the water tongue phenomenon. [0004] According to one aspect of the present disclosure, a method for processing a drainpipe is provided, including the following steps: [0005] placing the second end of the first initial tube...
