Project Name： Natural Gas Pipeline Crossing project
Project location：Ganjiang City Jiangxi Province
Pipe Specification：Φ508×10L415 straight saw pipe
Construction Equipment： GD8000-LLS HDD Machine
Soil condition: Sand、rock、Shale and sand stone
The project need through Jiangxi Ganjiang river, river bed geological condition is very complex, cross section including the fault zone, pebbles, sand layer and thick soft soil layer (including a lot of pebbles) and so on, When into the hole is more difficult, Angle and azimuth Angle is difficult to control, construction difficulty can’t be imagined. This project is domestic the largest and longest construction in recent years, the most complex geological trenchless directional crossing engineering.
