Novel grooving discharge pipe used for installation

Abstract

The invention relates to a discharge pipe, in particular to a novel grooving discharge pipe used for installation. The novel grooving discharge pipe used for the installation is composed of a water pipe body (1), wherein the cross section of the water pipe body (1) is ring-shaped, and 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), the included angle between the inclined plane (1-1-2) and the horizontal plane is 15 degrees, an annular boss (1-1-1-1) is arranged at the other end of the small outer diameter face (1-1-1), and an annular groove (1-2-1) is arranged at one end of the pipe inner diameter (1-2). According to the novel grooving discharge pipe used for the installation, a flange-type structure is formed to avoid leakage, the novel grooving discharge pipe used for the installation is reliable in sealing, good in tightness and reliability, moreover simple in structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to a sewage discharge pipe, in particular to a novel sewage discharge pipe for installation 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...

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
