Description

Technical Field

[0001] This utility model belongs to the field of trenchless repair construction technology for urban underground pipelines, and specifically relates to a tracked trenchless pipeline repair drum device. Background Technology

[0002] Urban drainage pipe networks are an indispensable and crucial infrastructure of modern cities. They are a fundamental industry with a comprehensive and leading impact on urban economic development, serving as the backbone of urban water pollution control, flood drainage, and flood prevention, and are an important indicator of a city's modernization level. Currently, most cities in my country repair underground pipelines by excavating and re-burying the pipes. With the progress of urbanization, urban underground pipelines have become increasingly complex, and the load on urban roads is becoming more and more severe, leading to numerous technical challenges in the repair process. As urban construction continues to improve, trenchless pipe laying, repair, and replacement technologies are increasingly favored by underground pipeline management departments due to their advantages, including no disruption to traffic, fast and efficient laying speed, no environmental damage, and no impact on people's normal work and life.

[0003] Trenchless pipeline repair technology first emerged in the oil and gas industry, primarily for the renewal and repair of oil and gas pipelines. It has since been gradually applied to the renovation and upgrading of water supply and drainage pipelines. Current trenchless pipeline repair technologies require transporting repair materials to the site to be repaired and then delivering them to the appropriate repair location. The repair materials need to be placed in special containers for transportation. Traditional transportation methods are unsuitable for long-distance, long-term transport of repair materials. If manual on-site scaffolding is used, a large number of workers are needed to turn the repair materials, which is time-consuming, labor-intensive, and poses safety risks. Furthermore, it cannot quickly meet the needs of multiple locations. Additionally, due to environmental factors, traditional wheeled transport equipment often requires pre-paved roads.
