Scope

This technology is an advanced underground pipeline construction method that uses self-locking sealing to complete the laying, replacement, or repair of pipelines without damaging the ground. Application scope: Municipal water supply and drainage: In municipal water supply and drainage projects, trenchless pipe jacking technology can effectively improve project efficiency, ensure construction quality, and have less impact on the environment and traffic. Sewage pipelines: In the construction of sewage pipelines, trenchless pipe jacking technology can reduce environmental pollution and improve construction efficiency. Integrated pipelines: Trenchless pipe jacking technology can also be applied to the construction of integrated pipelines, which typically include various different piping systems, such as water supply, drainage, power, and communications. In summary, trenchless pipe jacking technology has been widely used in various underground pipeline construction projects due to its low environmental impact, fast construction speed, and strong applicability.
