In the steelmaking plant in central Vietnam, 8units  XR280E pneumatic rotary drilling hammer drilling rigs were used to drill pile holes one by one.

Because the project is located in the middle of the mountain and the stratum environment is extremely complex, it is difficult to use conventional drilling rigs for pile foundation construction. The owner used crawler cranes to construct the DTH hammer equipment in the early stage. Not only the hole forming accuracy is poor, but also the construction efficiency is low. , unable to meet the normal construction period requirements.

After adopting the XR280E pneumatic rotary submersible drilling rig, the construction efficiency of the project has been greatly improved, and the drilling depth in one hour is as high as 10 meters. Its stable equipment performance and excellent hole forming efficiency have successfully completed the drilling tasks of each pile position. At present, 8 XCMG XR280E pneumatic rotary submersible drilling rigs have been distributed in various locations in the factory for drilling operations.

While the construction efficiency is improved, the local personnel stationed abroad provide special construction method training and equipment operation guidance to the on-site staff, and perform all-weather and full-cycle tracking services. The superb technology, high-end equipment and efficient services have won the favor of the owner. unanimous praise.

XR280E rotary drilling rig equipped with pneumatic down-the-hole hammer adopts a construction method specially designed for complex formations. It can quickly and efficiently complete drilling in various complex formations, and makes drilling more stable and accurate, effectively reducing the drilling process. error in .
