In 2025, with the acceleration of urbanization, the maintenance and renewal of urban underground pipeline systems are increasingly becoming crucial tasks in urban management. Traditional excavation-based repair methods are not only time-consuming and labor-intensive but also severely disrupt urban traffic and residents' daily lives. Against this backdrop, trenchless rehabilitation technology is gradually emerging as the mainstream choice for urban pipeline maintenance due to its unique advantages.

Trenchless rehabilitation technology represents an innovative approach to pipeline maintenance, utilizing advanced rock drilling equipment and technical means to repair underground pipelines without damaging the surface through methods such as guided drilling and subsurface tunneling. This technology not only avoids traffic congestion and environmental pollution caused by large-scale excavation but also significantly enhances repair efficiency and quality.

In recent years, trenchless rehabilitation technology has achieved remarkable results in urban pipeline maintenance. Whether it is municipal water supply and drainage pipelines, gas pipelines, or communication cable conduits, trenchless rehabilitation technology can provide precise and efficient solutions. By incorporating pipeline trajectory measurement and control, this technology can accurately locate pipeline defects and employ various repair methods, including pipe insertion, cured-in-place pipe (CIPP) lining, and spiral winding, among others.

Notably, trenchless rehabilitation technology also emphasizes environmental protection and sustainable development. During the repair process, environmentally friendly materials and techniques are adopted to minimize environmental damage and pollution. Moreover, this technology can extend the service life of pipelines and reduce maintenance costs, contributing to the sustainable development of cities.

Looking ahead, trenchless rehabilitation technology will play an even more critical role in urban pipeline maintenance. With continuous technological advancements and innovations, trenchless rehabilitation technology will become more intelligent and automated, providing a more solid foundation for the safe operation of urban pipeline systems. Simultaneously, relevant departments will continue to increase investment to promote the widespread adoption and application of trenchless rehabilitation technology, making urban life even better.
