Pollution discharge pipe used for installation of open groove method

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.

Description

technical field [0001] The invention relates to a sewage discharge pipe, in particular to a sewage discharge pipe installed by slotting method. The invention is suitable for use when discharging sewage underground. The invention belongs to the technical field of water supply and drainage device manufacturing and processing. Background technique [0002] In the underground water supply and drainage such as sewage treatment in many fields of water conservancy, industry and urban construction, the sewage pipe is an indispensable and important part, and is the basic component unit and important connection hub in the water supply and drainage pipe network system. Existing sewage pipes are varied. [0003] Wherein slotting method is installed and is also very various with blowdown pipe kind, is generally concrete cement pipe, and its structure is made up of the water pipe body that cross section is circular ring, and water pipe body includes pipe outer diameter and pipe inner d...

AI Technical Summary

Problems solved by technology

Although the sewage pipes installed by the slotting method are widely used at present, there are still the following defects: when the water pipe body is installed, the joints of the outer diameters of the adjacent pipes and the joints of the inner diameters of the pipes are poorly connected, resulting in poor sealing. prone to leakage
