Nanchuan-Pipeline laying site in Liangjiang New Area

Two XCMG horizontal directional drilling rigs work together

Double-machine cross-over，As soon as you cross the river！

2640 meters，One success!

EngineeringAcross the Yangtze River，The ground surface of the construction section is covered by silty clay.，The lower soil is mudstone and sandstone interbed.，The geology is complex。Directional drilling crossing section adoptsD406.4×10.0 L415MLSAW pipe，The crossing length is2640 meters，Depth up to143Meters，The minimum distance between the crossing pipeline and the bottom of the Yangtze River is84.66 meters。Operation capacity of construction equipment、Work efficiency is facing a very big test.。

XugongXZ6600 horizontal directional drilling rigDual engine power system，Speed regulation technology combined with multiple working conditions，Rotation、Push-pull multi-gear control technology，Maximum pullback force up to6600kN, Maximum giant slalom torques210000 N·m，Efficient construction with immediate effect。

In addition，XugongXZ6600 three cylindersGrip vise，The shackle torque is large，Vise can float all the way，ConvenientCasing methodConstruction process。The technical personnel of XCMG combined the equipment characteristics and site conditions.，RealizationXZ6600 andXZ3600 pairs of machines cross each other，AdoptDouble drill reaming constructionEngineering process，Press for successful completion of project“Accelerator key” 。

Configuration of two main machines during constructionRemote Internet of Things platform，The owner can check the tension.、Torque and other important data of drilling rig to achieve full process monitoring。At the same time，XCMG technical team can conduct data analysis in the cloud，Escort the completion of project。

As a veteran of XCMG's super-large tonnage directional drilling rig，XZ6600 andXZ3600 double machine cooperation，Cross the river efficiently，The project has also been highly recognized by the local government.。
