Modified pollution discharge pipe for installation of slotting method

Abstract

The invention relates to a pollution discharge pipe, in particular to a modified pollution discharge pipe for installation of a slotting method. The modified pollution discharge pipe for the installation of the slotting method consists of a water pipe body (1), wherein a cross section of the water pipe body (1) is round-ring-shaped. 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 face (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 face (1-1-2). An inclined angle between the inclined face (1-1-2) and a horizontal surface is 10 degrees. A ring-shaped boss (1-1-1-1) is arranged at the other end of the small outer diameter face (1-1-1). A ring-shaped groove (1-2-1) is formed at one end of the pipe inner diameter (1-2). The modified pollution discharge pipe for the installation of the slotting method has the advantages of forming a flange structure, preventing a leakage phenomenon from occurring, and being reliable in sealing, good in tightness, good in reliability, simple in structure, and low in manufacturing cost.

Description

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

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
