The Application of Long-Distance Curved Pipe Jacking in Power Pipe Construction

At present, trenchless technology is universally recognized by owner and the public for its beneficial and environmental friendly character. As one of the most mature trenchless techniques, slurry balanced pipe jacking is playing an important role in municipal pipeline construction. However, it is the first time for Xiamen to install a power pipe with 2000 mm in diameter and 5 meters in embedding depth using slurry balanced pipe jacking method, which is uncommon even around China. The power pipe was successfully installed after improvement of construction equipment and technology, which can be referenced by other large diameter power pipe construction engineering.
