U-shaped double-wall socket and spigot type pipe joint and installing method thereof

Abstract

The invention discloses a U-shaped double-wall socket and spigot type pipe joint and an installing method thereof. The U-shaped double-wall socket and spigot type pipe joint comprises a socket end anda spigot end. The socket end and the spigot end are used for being connected with the head and the tail of a common pipe section correspondingly to form a unit pipe section. The socket end is provided with a U-shaped slot formed by double layers of pipe walls. The spigot end is formed by a single layer of threadless round pipe wall. A buckle is arranged between the socket end and the spigot end.When pipe sections are connected in a sleeved mode, one spigot end is inserted in the corresponding U-shaped slot and is connected with the corresponding socket end through the corresponding buckle. The deficiency of a traditional plastic pipeline socket and spigot type joint is overcome, the anti-seismic effect is good, vertical rigidity is high, leakproofness is good, and installation is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of drainage engineering pipelines, in particular to a U-shaped double-wall socket-type pipeline interface and an installation method thereof. Background technique [0002] With the rapid development of my country's economy, the country is gradually accelerating the construction of urban infrastructure, and the construction of drainage pipe network is one of the most important projects. The drainage system is the conscience of a city, and it is also an important supporting facility for urban municipal roads. The investment in the construction of pipe networks for urban transformation is also increasing year by year. At present, urban drainage pipe network projects generally include the construction of rainwater and sewage pipe networks in new urban areas, the renovation of rainwater and sewage pipe networks in old urban areas, and the construction of sponge city facilities. A good drainage pipe network syste...

Problems solved by technology

It can be seen that the infiltration of groundwater is quite serious. A large amount of infiltration of groundwater will increase the flow of drainage pipes, increase the economic investment of sewage plants, and cause unnecessary losses to the national economy.

[0006] (2) Pollution of groundwater sources: Leakage of the sewage pipe interface will cause sewage leakage, and a large amount of ammonia nitrogen, nitrate, sulfate, organic matter, etc. will seep into the groundwater along with the sewage, causing the organic matter and inorganic salts in the groundwater to exceed the standard, seriously endangering the quality of the groundwater

[0010] (1) The rubber sealing ring is not positioned, the circumference of the rubber ring cannot guarantee a uniform compression ratio, and its sealing performance cannot be guaranteed, resulting in leakage;

[0011] (2) The depth of the socket joint cannot be precisely controlled, and the installation workers often determine the depth based on construction experience, which cannot guarantee that the socket is in place.

[0012] (3) The traditional socket interface relies on the friction between the socket and the socket to squeeze the rubber ring. Before the pipeline is backfilled, the water in the pipe ditch floats the pipe or the soil disturbance during backfilling will easily lead to the dislocation of the interface.
