The key housing construction project in a major Asian city is under vigorous construction,XCMG XR240E rotary drilling rig,facing stringent standards of tight schedules and high construction quality requirements.

The average construction time for a single pile foundation is only 5 hours,winning high customer recognition with stable construction performance and escorting the project's steady construction throughout.

The geological conditions at this construction site are complex, with the site area dominated by soil layers and clay layers; the strata alternate between soft and hard, and moisture content fluctuates greatly, making it highly prone to problems such as deviation of holes, diameter shrinkage, and hole collapse. At the same time, urban construction strictly limits vibration and ground settlement,placing extremely high demands on equipment construction precision and stability。

Considering the complex working conditions and comprehensive performance, the construction party ultimately selectedthe XCMG XR240E rotary drilling rigand fully trusted its solid strength and stable quality in complex strata. Facing multiple construction challenges, the XCMG XR240E overcame them one by one relying on core technologies. The equipment is equipped withintelligent pressurization and torque adaptive technologywhich can adapt in real time to formation changes and adjust drilling parameters, avoiding pile defects from the source;the optimized hydraulic system precisely matches power outputbalancing construction efficiency with energy conservation and environmental protection.

The equipment's drilling diameter can reach 1000-1500 mm,with a single-hole drilling depth of 35-40 m，and the average construction time for a single pile foundation is only 5 hourswhich strongly supported the project's continuous operation and on-schedule progress. In response to the pain point of clay-layer bit balling, XCMG also provided dedicated drilling tools and mud proportioning solutions, thoroughly resolving construction bottlenecks.

 The local project manager highly recognized the equipment and service:XCMG equipment is outstanding in quality and is also paired with professional construction solutions that specifically solve the construction difficulties in clay layers. It is our capable partner in tackling the project.
