Pipe member

Abstract

The invention discloses a pipe member which comprises a pipe member body formed by splicing one or more pipe bodies and one or more expansion adapting pieces. The pipe member body is embedded in a pre-buried cavity with two sides limited, one expansion adapting piece is installed between every two adjacent pipe bodies, the pipe bodies on the two sides are connected through the expansion adapting pieces, the total length of the whole pipe member body is larger than the length of the pre-buried cavity, the expansion adapting pieces of the whole pipe member body are squeezed and buried in the pre-buried cavity, the two sides of the pipe member body are limited through the pre-buried cavity, and the extruded expansion adapting pieces protrude outwards to form a support ring in contact with thebottom surface of the pre-buried cavity for supporting. The pipe member has very good compression resistance and shear resistance; and even if the whole pipe member is divided into two parts, the pipe member can be slowly restored from shape changes, the water discharge amount is reduced, and the loss of water sources is further reduced.

Description

technical field [0001] The invention relates to the field of pipelines, in particular to a pipe fitting. Background technique [0002] In the prior art, pipe fittings are generally used for the long-distance transmission of gas and fluid, but the general pipe fittings are made of PVC plastic, and when they are buried in the ground or arranged on the ground for discharge, they often break. Some of the ruptures are caused by external environmental influences, and some are caused by external force cutting, but once such pipes are cut or ruptured, or a large amount of resource loss occurs, if it is a water pipe, a large amount of water will flow out, causing serious damage to water resources. Waste, and the pipeline is generally in direct contact with the bottom surface of the pipeline. Because of the rigid contact between the two, the compressive capacity is poor. Once there is some extrusion, the pipe fittings may rupture, and the compressive performance is poor. Contents of...

[0002] In the prior art, pipe fittings are generally used for the long-distance transmission of gas and fluid, but the general pipe fittings are made of PVC plastic, and when they are buried in the ground or arranged on the ground for discharge, they often break. Some of the ruptures are caused by external environmental influences, and some are caused by external force cutting, but once such pipes are cut or ruptured, or a large amount of resource loss occurs, if it is a water pipe, a large amount of water will flow out, causing serious damage to water resources. Waste, and the pipeline is generally in direct contact with the bottom surface of the pipeline. Because of the rigid contact between the two, the pressure resistance is poor. Once there is some extrusion, the pipe may rupture, and the pressure resistance is poor.
