Abstract

The invention relates to a pollution discharge pipe, in particular to the pollution discharge pipe used for installation of an open groove method. The pollution discharge pipe is composed of a water pipe body (1) with a circular cross section. The water pipe body (1) comprises a pipe outer diameter (1-1) and a pipe inner diameter (1-2). The pipe outer diameter (1-1) is composed of a small outer diameter face (1-1-1), an inclined plane (1-1-2) and a large outer diameter face (1-1-3). One end of the small outer diameter face (1-1-1) is connected with the large outer diameter face (1-1-3) through the inclined plane (1-1-2). An inclined angle of 5 degrees is formed between the inclined plane (1-1-2) and a horizontal plane. An annular boss (1-1-1-1) is arranged at the other end of the small outer diameter face (1-1-1). An annular groove (1-2-1) is formed at one end of the pipe inner diameter (1-2). The pollution discharge pipe used for the installation of the open groove method has the advantages of being in a flange-type structure, preventing a leakage phenomenon from occurring, and being reliable in sealing, good in tightness, good in reliability, simple in structure and low in manufacture cost.
