What are the advantages of using pipe jacking technology?

The excavation engineering technology completely solves the problems such as the damage to urban buildings and the congestion of road traffic in the pipeline laying construction, and highlights its advantages in stabilizing soil layer and environmental protection. This is very important for cities with heavy traffic, dense population, many ground buildings and complex underground pipelines. It will create a clean, comfortable and beautiful environment for the city.

Pipe jacking technology is a term that has been frequently used in recent years. It involves the laying or replacement of underground pipelines by using less excavation, that is, the working well and receiving well should be excavated, and no excavation, that is, the pipeline should not be excavated. The pipe jacking diameter is dn800-4500. Push the pipe to be jacked into the receiving well through the working well. The pipe in a working well can travel more than 1500 meters underground, and can also travel in a curve to bypass some underground pipelines or obstacles.

Its technical point is to correct the deviation of the pipe extending underground. It is especially suitable for laying large and medium-sized non excavated pipe diameters. It has the comprehensive functions of economy, high efficiency and environmental protection. The advantages of this technology are: no ground excavation; No demolition or destruction of ground buildings; Do not damage the environment; It does not affect the segment difference deformation of the pipeline; Time saving, high efficiency, safety and low comprehensive cost.

This technology is widely used in the trenchless laying of urban underground water supply and drainage pipelines, natural gas and oil pipelines, communication cables and other pipelines in the economically developed coastal areas of China. It can cross roads, railways, bridges, mountains, rivers, Straits and any buildings on the ground. This technology can save a large amount of land acquisition and demolition costs, reduce environmental pollution and road congestion, and has remarkable economic and social benefits.
