Pipe jacking is a project that is not easy to construct well, and it is also a less well-known project.

Trenchless engineering technology has completely solved the problems of the destruction of urban buildings and the blockage of road traffic in the pipeline burying facility, and highlighted its advantages in stabilizing the soil layer and environmental protection. This is very important for cities with heavy traffic, dense population, numerous ground buildings and complex underground pipelines. It will create a clean, comfortable and beautiful environment for the city.

Trenchless technology is a term that has only been frequently used in recent years. It involves the use of less excavation, that is, the working well and receiving well must be excavated, and no excavation, that is, the pipeline does not excavate technology to carry out underground pipelines. For laying or replacement, the pipe jacking diameter is DN800-4500. The pipe to be buried is pushed into the soil through the working well. The pipe in a working well can travel more than 2,000 meters underground and can also travel in a curve to avoid some underground pipelines or obstacles.

Its technical point is to correct the deviation of the pipe extending underground. Especially suitable for the trenchless laying of large and medium pipe diameters. It has comprehensive functions of economy, efficiency and environmental protection. The advantages of this technology are: no excavation of the ground; no demolition, no damage to the ground buildings; no impact on traffic; no damage to the environment; construction is not affected by climate and environment; does not affect the deformation of the pipeline; time-saving, efficient, Safe and low overall 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 my country. It can cross roads, railways, bridges, mountains, rivers, straits and any buildings on the ground. Construction with this technology can save a large amount of land acquisition and demolition costs, reduce environmental pollution and road blockage, and has significant economic and social benefits.
