The first big bore and longest directional drilling crossing in China, a record for XCMG!

October 08, 2023

Recently，Sino-Russia Eastern Natural Gas Pipeline Project（Yongqing-Shanghai）Nantong-Perfect Completion of Sigujing Section of Zuchongzhi Road in the Fourth Bid Section of Luzhi Line Construction，AmongXugongXZ11000 horizontal directional drillingPlay a huge role。

The crossing project is located in Bacheng Town, Kunshan City, Suzhou City, Jiangsu Province.，Pipeline crossingActualLength 1558.16m，Borehole diameter 1850mm。
Poor local engineering geological conditions，The two ends facing the project are mostly muddy clay.，Poor pore-forming property and bearing capacity，Large diameter drill bit is easy to sink，Resulting in a trajectory offset；Silty clay in horizontal section，A little carelessness in the construction process is prone to the phenomenon of soil holding drilling.，XZ11000 horizontal directional drilling machineWith strong power and stable performance，Go throughLevel 7 reaming，Finally, the task was completed perfectly.。

XZ11000 Horizontal Directional Drilling Rig is a super-large tonnage Horizontal Directional Drilling Rig developed by XCMG to meet the needs of users.。Its rotation speed is fast.、The torque is large、The pushing and pulling force is large、The push-pull speed is high，Maximum pullback force up to11000kN, Maximum giant slalom torques240000N·m， Particularly suitable for long distances、Large pipeline crossing。
XugongXZ11000 Horizontal Directional Drilling Rig Configuration XCMG Core Patent Technology—“Torque self-adaptiveDynamic cruise construction”，As well as multi-condition speed regulation and rotation、Push-pull multi-gear control technology。Can adapt to independent learn of construction under different work condition，The operation is convenient and stable，And reduce that labor intensity、And that construction efficiency is increase。

Configuration of the construction partyXugongXZ11000 horizontal directional drilling machine+ XMP2800 Mud Pump Station，In the construction process, automatic start and stop or one-key idling function can be realized according to the construction status.，Greatly save mud consumption。Intelligent remote control、Flow control、State detection、Fault Diagnosis Technology Saves Engineering Cost，Greatly improve engineering efficiency。

The construction unit has cooperated with XCMG for many years.，XCMG horizontal directional drilling rig was used as the main construction force to set the fastest construction record in the Yellow River crossing of the eastern route between China and Russia.，This cooperation has created the longest crossing distance construction record of 1422 pipe diameter.。Construction reliability of XCMG equipment by users、Highly affirm the timeliness of service，And look forward to more cooperation in the future.！
