 XCMG directional drillingXZ5060 

Set another local record for the longest crossing

Overseas journey，Set another record

Recently，XugongXZ5060 Horizontal Directional Drilling Rig Appears Overseas，AndXZ2860 joint construction，Boosting Submarine Laying of Natural Gas Pipeline。

The project has a length of 2940 meters.、Record of horizontal directional drilling with a depth of 80 meters，It's done“The Belt and Road”Another masterpiece of infrastructure construction in countries along the line！

Before that，As XCMG super-large tonnage directional drilling rig，XugongXZ5060 has been in the large-scale crossing construction task of Wuyuer River.，The maximum crossing distance is fixed at 2630 meters.。

Subsea construction，The difficulty is not small

The engineering supervisor of this construction project isD762mmNatural gas pipe，At the same time, a 6-inch optical cable tube was laid.。

The stratum in the crossing area is expansive clay.、Silty sand，It is easy to shrink during construction.、Hold the drill；Sea water has a high salt content，Difficulty in slurrying bentonite，Slag-carrying mud、Very poor wall protection performance，Difficulty escalation of long-distance guided crossing and pullback reaming on the seabed。

In view of engineering difficulties，XCMG technicians adjust the construction scheme，Double drilling machine penetration technology and double drilling machine reaming construction technology are adopted.，Entry from equipment、 Put 、Debugging，To drill rig operation training、Process and method, etc，Provide a complete set of solutions for overseas customers，Ensure the completion of the project with high quality and efficiency。

XZ5060+XZ2860，Dual synchronization

XugongXZ5060 Horizontal Directional Drilling Rig is built by XCMG to meet the needs of customers.，Independently developed large-tonnage Horizontal Directional Drilling Rig。
Its rotation speed is fast.、The torque is large、Strong pushing and pulling force，The most giant slalom torque is the 16000.N·m，The maximum pushing and pulling force can reach 5300kN，Suitable for large aperture、Long distance working condition crossing。
The process of wearing this time，AdoptedXCMG's unique double-machine synchronous reaming technology：
XugongXZ5060 is used as the main drilling rig，On one side“Drawing and reaming”，XZThe 2860 rig is on the unearthed side.，Carry out follow-up construction except for reverse rotation……Double Computer Cooperative Operation，Reduce construction time while increasing construction torque，It ensures smooth traffic across the Taiwan Strait.。

In this construction, XCMGXZ5060 Horizontal Directional Drilling Rig Perfectly Overcome the Difficulty of Long-distance CrossingWin recognition from overseas customers for domestic equipment endorsement with strength and performance！
