The commercial complex project has a clear plan and diverse functions: the first floor is a parking lot, the second floor features a commercial and entertainment street, and the third floor accommodates a hotel and business office area. It is a key local livelihood and commercial supporting project. The project geology is dominated by strongly weathered rock strata, with high formation hardness and great difficulty in hole formation, placing stringent demands on the equipment's rock-penetration capability and construction efficiency.

During construction, the Yuchai YCR135 rotary drilling rig easily handled complex rock-stratum conditions thanks to its strong power and stable performance. With ample torque and precise hole formation, the equipment effectively overcame the drilling challenges of strongly weathered rock strata and greatly shortened the hole-formation cycle; the whole machine offers flexible control and a low failure rate, operating efficiently throughout to ensure steady construction progress, perfectly matching the high requirements and high-efficiency standards of overseas projects.
