Description

Technical Field

[0001] The utility model relates to the technical field of supporting devices, in particular to a local supporting device for municipal trenchless pipeline repair. Background Art

[0002] The localized support device for municipal trenchless pipeline repair is a highly effective tool for repairing underground pipelines, particularly in urban environments where large-scale excavation is inconvenient. Using a trenchless technique, the device performs repairs directly within the pipeline, avoiding the traffic disruption, environmental damage, and high costs associated with traditional excavation repairs. Localized support devices are typically made of high-strength, corrosion-resistant materials such as fiberglass-reinforced plastic (FRP) or polymers. These materials can withstand the pressure and chemical attack within underground pipelines while providing durable support. The device's design takes into account the shape and size of the pipeline and can be customized to accommodate various pipe types and specifications. During use, the localized support device is positioned within the pipeline using specialized equipment. Once positioned, it expands according to a pre-programmed procedure or operator control, conforming tightly to the pipe's interior. This tight fit effectively supports the pipeline and prevents further deformation or damage. The device also seals cracks and leaks within the pipeline, preventing groundwater and impurities from entering, ensuring a leak-tight and fully functional pipeline. The use of local support devices greatly shortens the repair time and reduces the impact of construction on urban life. It is an environmentally friendly, economical and efficient pipeline repair technology.

[0003] At present, the existing pipeline support device is generally designed similar to a cylindrical tube. However, the cylindrical tube is inside the pipeline. When the pipeline is erected for repair, the cylindrical tube and the pipeline may rotate relative to each other. The rotation of the pipeline outside the cylindrical tube may cause the device to be unable to accurately align with the repair position, affecting the repair effect. Therefore, it does not meet the existing needs. In response to this, we have proposed a local support device for municipal trenchless pipeline repair. Utility Model Content
