Socket and spigot type flexible connector reinforced concrete drainage pipe and machining process thereof

Abstract

The invention discloses a socket and spigot type flexible connector reinforced concrete drainage pipe and a machining process thereof. The socket and spigot type flexible connector reinforced concretedrainage pipe comprises a drainage pipe body, a pipeline connector is arranged at one end of the drainage pipe body, positioning through holes are formed in the two sides of the pipeline connector, apipeline connecting structure is arranged at the end, away from the pipeline connector, of the drainage pipe body, the pipeline connecting structure comprises an outer connecting ring and an inner connecting ring, a connecting circular groove matched with the pipeline connector is formed between the outer connecting ring and the inner connecting ring, a concrete pouring opening is formed in the top of the outer connecting ring, positioning grooves are formed in the two sides of the inner connecting ring, inserting-connecting through holes are formed in the positions, on the same horizontal plane of the positioning grooves, of the two sides of the outer connecting ring, and positioning rods are movably arranged in the inserting-connecting through holes. The socket and spigot type flexibleconnector reinforced concrete drainage pipe has the beneficial effects that the device is simple in structure and convenient to connect and fix, after the device is fixed, the sealing performance is good, the situation of water leakage is avoided, and the overall structural strength of a pipeline is high.

Description

technical field [0001] The invention relates to the technical field of drainpipe manufacture, in particular to a socket type flexible interface reinforced concrete drainpipe and its processing technology. Background technique [0002] With the rapid advancement of urbanization, many sewage treatment plants have been built or planned to be built in large and medium-sized cities in my country. A large amount of industrial wastewater and domestic sewage enter the sewage treatment plant through drainage pipes for centralized treatment. Most of the drainage pipes use reinforced concrete drainage pipes. The cement used for drainage pipes usually uses green and environmentally friendly cement. Drainage pipes are mainly used in underground sewage pipe network projects. During use, they mainly play the role of transporting sewage, carrying the weight of soil, vehicles and accumulations on the soil. [0003] In the authorized patent of Chinese patent CN201103753Y, a pipe material of co...

AI Technical Summary

Problems solved by technology

[0004] When the above-mentioned drainage pipes are in use, the connection between the pipe bodies is not tight enough, resulting in the leakage of sewage in the drainage pipes, which has an impact on the environment, and its bearing capacity is not strong enough, and the weight of the vehicle and the covering soil is easy to cause rupture
