Project Name:Yangtze Revier and Shahu Lake Water Environment Improvement Project

Project Location:Wuchang District, Wuhan, Hubei Province

Total Length of the Project:5.439 km

Geological Condition: Silty clay

Construction Feature and Challenge:

1.Sharp curve pipe Jacking

2.Long distance pipe jacking

3.Underwater pipe jacking

4.Large diameter pipe jacking

 

The radius of curvature is only 600m, which is smaller than the outer diameter of the pipe. The jacking axis is not easy to accurately control, and it is easy to deviate from the design axis. In addition, the curve section is long, and the internal visibility of the pipeline is not good, which makes the jacking construction measurement difficult. The longer the pipe jacking distance is, the more difficult the construction techniques such as grouting drag reduction, relay ability, power supply in the tunnel, and underground transportation will be.

 

Equipment model and features:

Φ 3500 slurry, large pipe diameter, long jacking distance
