New construction of the main plant of an integrated steelmaking plant in central Vietnam，8 sets of XCMGXR280EPneumatic rotary drilling down-the-hole hammer drilling machine is busy in construction。With the laying of pile holes one by one，In the near future，This piece of land is more than 4200 mu.，There will be 5.5 million tons of steel output every year.。

Due to the mountainous location of the project，The stratigraphic environment is extremely complex.，It is difficult to construct pile foundation with conventional drilling rig.，The Owner used the down-the-hole hammer equipment modified from the crawler crane for construction in the early stage.，Not only the pore-forming accuracy is poor,，And the construction efficiency is low.，Unable to meet the normal construction period requirements。

In useXR280EPneumatic rotary drilling down-the-hole hammer drillAfter construction，The construction efficiency of the project has been greatly improved.，Up to 10 meters in one hour，Its stable equipment performance and excellent hole-forming efficiency have successfully completed the drilling task of each pile position.。At present，8 sets of XCMGXR280EThe pneumatic rotary drilling down-the-hole hammer drilling machine has been drilling at various locations in the plant area.。

While improving construction efficiency，The local personnel stationed abroad shall provide training on special construction methods and equipment operation guidance to the on-site staff，Fulfill 24/7、Full-cycle tracking service，Superb technology、High-end equipment、Efficient service，Be unanimously praised by the owner。

XR280EThe rotary drilling rig is equipped with pneumatic down-the-hole hammer, and the construction method specially designed for complex strata is adopted.，It can be used in a variety of complex formations.Fast、Finish the hole efficiently，AndMaking the borehole more stable、Precise，ValidReduce errors in the drilling process。

The Pneumatic Dth Hammer Construction Method of XCMG Rotary Drilling Rig Configuration Really Stands in the Customer's Perspective，Realize cost reduction and efficiency increase of the project。
