Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, specifically a trenchless integrated repair device for large-diameter pipelines. Background Technology

[0002] Pipeline systems play a crucial role in urban infrastructure construction, transporting various fluids such as water, gas, and sewage. However, over time, pipelines are affected by various factors, such as corrosion, wear, and geological changes, leading to problems like damage and leaks. Traditional pipeline repair methods typically require excavation, which not only severely impacts traffic and the environment but also involves long construction periods and high costs.

[0003] To address these issues, trenchless pipeline repair technology has emerged. This technology allows for pipeline repair without damaging the ground, offering advantages such as high construction efficiency and minimal environmental impact. However, during the trenchless overall repair of large-diameter pipelines, external forces can cause parts of the pipeline's inner wall to contract inwards, potentially leading to pipeline damage over time.

[0004] Existing repair methods typically involve moving the repair device to the area to be repaired and using hydraulic rods and extension components to compress the repair plate, causing the contracted inner wall to recover. However, most existing repair devices experience wobbling during the compression repair process, making the device unstable and affecting the normal progress and quality of the repair work. Therefore, developing a trenchless integrated repair device for large-diameter pipelines that can effectively solve the above problems is of significant practical importance. Utility Model Content
