Sewage drainage pipeline structure

Abstract

The invention relates to a sewage drainage pipeline structure and belongs to the technical field of drainage pipelines, the sewage drainage pipeline structure comprises a plurality of pipe joints and connecting seats, every two adjacent pipe joints are connected through the corresponding connecting seat, connecting pieces are installed at the two ends of each pipe joint respectively, and two connecting grooves are formed in each connecting seat; the ends, close to each other, of every two adjacent pipe joints are inserted into the connecting bases respectively, the corresponding connecting pieces are clamped into the connecting grooves, each connecting piece comprises a cylinder, the cylinders are arranged in the pipe joints in a penetrating mode, one end of each cylinder is located outside the corresponding pipe joint, a turned-over edge is machined at the end, located outside the corresponding pipe joint, of each cylinder, and the turned-over edge is located outside the corresponding pipe joint. The flange extends away from the center of the cylinder, an included angle is formed between the flange and the outer wall of the cylinder, the included angle is an acute angle, the connecting groove is formed in an inclined mode, and the inclination direction of the connecting groove is matched with the inclination direction of the flange. The connecting structure has the effect that the adjacent pipe joints are connected more stably.

Description

technical field [0001] The present application relates to the technical field of drainage pipes, in particular to a sewage drainage pipe structure. Background technique [0002] In the process of modern city construction, rainwater pipes and sewage pipes are important components. Stormwater pipes are pipes that collect natural rainwater on the ground and transport it to natural water bodies. Sewage pipes are pipes that collect sewage that has been used by people. Usually, the sewage pipe needs to transport the sewage to the sewage treatment plant to meet the discharge standard and then discharge it into the water body or for recycling. [0003] At present, sewage pipelines are usually formed by splicing sections of pipe sections in sequence. The splicing method of two adjacent pipe sections is generally plug-in connection. This connection method is not stable enough. During the flow of sewage in the pipeline, the pipeline is washed, which is easy to cause The joints of th...

AI Technical Summary

Problems solved by technology

[0003] At present, sewage pipes are usually spliced ​​by sections of pipe joints sequentially. The splicing method of two adjacent pipe joints is generally plug-in. This connection method is not stable enough. During the flow of sewage in the pipeline, the pipeline will be scoured, which will easily cause The connection of the pipe joint is damaged, which will cause sewage leakage

[0004] During the research and improvement, the R&D personnel found that there is a defect that the connection of adjacent pipe sections is not stable
