Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a pipeline repair liner. Background Art

[0002] There are many types of underground pipelines in cities, crisscrossing each other, especially transportation pipelines, such as water pipes, heating pipes and other types of pipes, which have certain pressures. These pipes leak and fail due to damage caused by construction problems or disrepair. If they are repaved, it will cause a large amount of investment in human, material and other social resources, and will have a great impact on people's production, life, travel and environment in the construction area.

[0003] In the patent document with publication number CN212226409U, a pipeline repair liner is disclosed. The device is composed of a plurality of convex arcs and concave arcs smoothly connected through the cross section of the liner. The convex arcs and the concave arcs are connected to form a plum petal-shaped overall structure. The cross section of the liner of the utility model is a plum petal-shaped structure, and its contour outer diameter is reduced compared with the outer diameter of the traditional round liner, so that a larger gap is maintained between the outer diameter of the liner and the inner diameter of the repaired pipeline, which greatly reduces the traction force and effectively eliminates the risk of damage to the liner due to excessive traction.
