Resin-mixed pipe manufacturers discuss pipe jacking construction techniques.

Pipe jacking is a challenging and lesser-known project.

Trenchless construction technology addresses challenges such as damage to urban buildings and traffic congestion during pipeline installation, demonstrating its advantages in soil stabilization and environmental protection. This is crucial for cities with heavy traffic, dense populations, numerous surface buildings, and complex underground pipelines, creating a clean, comfortable, and beautiful urban environment.

Trenchless technology, a term that has only become increasingly common in recent years, encompasses the laying or replacement of underground pipelines using minimal excavation (i.e., working and receiving shafts) or no excavation (i.e., no trenching of the pipeline). Pipe jacking techniques range from DN400 to DN4500. Pipes are pushed into the ground through working shafts. Pipes in a single working shaft can travel over 2.000 meters underground and can even curve to circumvent underground pipelines or obstacles.

The key technical aspect is correcting for deviations in the pipe's underground extension. This technology is particularly suitable for trenchless laying of large and medium-sized pipes. It offers comprehensive advantages, including economical, efficient, and environmentally friendly features. Advantages include: no excavation required, no demolition or damage to above-ground structures, no disruption to traffic, no environmental impact, and no impact on weather and environmental conditions. It also minimizes pipe segment deformation and is time-saving, effective, and safe, with a low overall cost.

This technology is widely used in my country's economically developed coastal areas for the trenchless laying of various pipelines, including urban underground water supply and drainage pipelines, natural gas and oil pipelines, and communication cables. It can cross roads, railways, bridges, mountains, rivers, straits, and any above-ground structures. Using this technology can significantly save on land acquisition and demolition costs, reduce environmental pollution, and reduce road congestion, resulting in significant economic and social benefits.
