Description

Technical Field

[0001] The utility model relates to the technical field of pipeline equipment, in particular to a non-excavation repair sleeve device for pipelines. Background Art

[0002] The non-excavation repair sleeve device for pipelines is a technology for pipeline repair, which allows the repair of damaged or aged pipelines without excavating the ground. This technology is particularly suitable for the maintenance of urban infrastructure because it can reduce the impact of construction on traffic, the environment and surrounding buildings. For pipelines damaged due to corrosion, wear or other reasons, non-excavation repair can provide a quick and cost-effective solution. In some cases, the pipeline may need to be strengthened to withstand higher pressures or loads. The sleeve device can provide additional structural support. The use of the non-excavation repair sleeve device for pipelines can significantly improve the efficiency and effectiveness of pipeline maintenance while reducing the interference to urban life;

[0003] The Chinese patent authorization announcement number is CN221463239U, and the name is a non-excavation repair sleeve for pipelines, including a pipeline, a fixed column and a first arc plate. Both ends of the fixed column are fixedly connected with handles. A plurality of inner cavities are arranged inside the fixed column. Springs are fixedly connected to the inner sides of the inner cavities. One end of the spring away from the inner cavity is fixedly connected with a sliding plate. A connecting rod is fixedly connected to the side of the sliding plate away from the spring. A leak stoppage plate is fixedly connected to the outside of the connecting rod. A support rod is fixedly connected to the inner side of the first arc plate. A second arc plate is rotatably connected to the outside of the support rod. The non-excavation repair sleeve for pipelines achieves the effect of facilitating the user to repair the pipeline, and at the same time avoids the sealing problem of the airbag;

[0004] The deficiencies of the above solution are as follows: Although the above solution can repair the pipeline, the repair position cannot be moved during repair.
