Development of pipe jacking in China

There are three most popular equilibrium theory in the pipe jacking construction: Pressure balance, balance, and soil pressure balance theory. The most prominent feature of pipe jacking construction is adaptation.

According to different geological conditions, construction conditions and the design requirements, selection and adaptation of the pipe jacking construction method, how to choose the right pipe jacking and supporting auxiliary equipment, for pipe jacking construction will be critical.

After years of development, the pipe jacking construction technology in our country has been a lot of practical engineering application, and maintained a high-speed growth, no matter in technology, equipment and pipe jacking construction technology has made great progress, and even in some respects has reached world leading level.

In 2001, Shanghai tunnel Co., LTD. in changzhou of jiangsu province completed a 2050 m long, 2 m diameter reinforced concrete pipe pipe jacking engineering, is now completed the longest pipe jacking project in our country.

From August 2001 to December jiaxing sewage treatment a sea into the top 2050 m long distance reinforced concrete pipe jacking, due to the choice of pipe jacking machine type, successfully solves the drag reduction mud apply and axis control and other technical problems. In about 5 months to complete all the jacking construction, creates the new pipe jacking construction record. Total length of 3600 m, diameter of 1.8 meters of steel pipe from 23 to 25 meters deep underground in September 2002 success across the Yellow River, whether into the length from the top, buried depth, geological conditions, or the first time in domestic steel pipe diameter.
