This project is located on an expressway in Guangdong. Subgrade settlement occurred along the route, resulting in pavement cracks and bumpy driving, which brought hidden dangers to traffic safety. Grouting reinforcement was carried out to eliminate subgrade defects.

Xingda XD-180 Mini Crawler DTH Drill Rig was selected to complete drilling for grouting holes.

Key Performance Advantages of XD-180

1. Compact & Flexible, Excellent Site Adaptability Small overall dimension and small turning radius. It works well in narrow working areas such as expressway partial lane occupation and municipal road construction zones, enabling flexible movement within traffic control sections.
2. Crawler Chassis, Pavement-Friendly The low ground-pressure crawler enables direct driving on asphalt pavement without damaging the original road surface, eliminating extra pavement protection measures.
3. Powerful Drilling Capacity & High Efficiency Adopting pneumatic DTH drilling technology, the rig achieves efficient borehole formation in soil and weathered rock with good hole straightness, meeting precision requirements for subgrade grouting holes.
4. Integrated Structure for Easy Transportation All driving, drilling and travelling systems are integrated on one unit. The rig can be transported by small trailers, greatly saving time for site mobilization and relocation.
5. User-friendly Operation & High Reliability Intuitive control system and convenient daily maintenance. Low failure rate under long continuous working conditions, perfectly matching non-stop road maintenance operations.

The construction site featured heavy traffic and complex working surroundings. Xingda technicians provided full-time on-site support, guiding the construction team to operate in accordance with standards and optimize construction procedures. While strictly complying with safety standards and guaranteeing reinforcement quality, we minimized traffic disruption and successfully completed the subgrade settlement treatment.

The XD-180 mini crawler DTH drill rig is widely used in expressway settlement remediation, municipal road reinforcement, slope anchoring, pipeline supporting drilling and other municipal & traffic geotechnical projects. Focused on R&D and manufacturing of geotechnical drilling equipment, Xingda provides high-performance drilling rigs and one-stop on-site technical support for highway maintenance and municipal infrastructure projects nationwide.
