Embodiment Construction

[0029] Under many complex working conditions, the pipeline cannot be completely opened. For example, the diameter of small pipelines such as water and sewage in residential buildings is fixed, and the ground cannot be damaged, but the pipeline still needs to be replaced, repaired or installed. When laying the pipeline network during construction, there are Other lines cannot be fully excavated for open construction environments, etc. The pipes used in the current pipelines are mainly divided into two types. One is the hard pipe with high rigidity, high strength and poor deformation ability. This kind of pipe has a thick wall and cannot be deformed after forming. Satisfy some non-standard size situations; the other is soft pipe with small rigidity, low strength and good deformation ability. This kind of pipe has a thin wall, although it has a certain deformation ability, it has small Damaged, soft pipes are prone to accumulate impurities and dirt, resulting in blockages, and th...

Abstract

The invention provides a deformable self-connecting self-repairing pipeline, and relates to the technical field of pipelines. The pipeline is made from a shape memory material, and a microcapsule structure is embedded in the shape memory material; the pipeline comprises at least two shaping parts and a deformation part, wherein the deformation part is arranged between the two shaping parts, and atriggering part is arranged on the inner wall of the end part of the pipeline. Compared with the prior art, the deformable self-connecting self-repairing pipeline has the properties of low density, high strength, corrosion resistance, fatigue resistance and the like, and further has the characteristics of variable rigidity, self-repairing and self-connection, namely the pipeline can be deformed and bent under external driving conditions, can be connected without other parts, can be automatically repaired the damaged parts, and is convenient to install, replace and maintain.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a deformable self-connecting and self-repairing pipeline. Background technique [0002] The application of pipelines can be seen everywhere in life, from the daily water and sewage pipelines to the installation of large-scale transmission pipelines such as pipe networks during construction, the impact of pipelines on life is very important. [0003] Under many complex working conditions, the pipeline cannot be completely opened. For example, the diameter of small pipelines such as water and sewage in residential buildings is fixed, and the ground cannot be damaged, but the pipeline still needs to be replaced, repaired or installed. When laying the pipeline network during construction, there are Other lines cannot be fully excavated for open construction environments, etc. The pipes used in the current pipelines are mainly divided into two types. One is the hard pipe with high ...
