Uniroc's L2 Fully Computerized Face Drill Rigs Its Grand Debut, Ushering in A New Era of Intelligent Rock Drilling

In response to the China State Railway Group and construction entities' requirements for mechanization, informatization, and automation in tunnel construction, Wuxin Equipment has successively launched the L0, L1, and L2 series of face drill rigs since 2017. These models represent a leap forward in technology, progressing from electric control and semi-computerized systems to fully computerized operation. The comprehensive product line covers tunnel projects across multiple sectors including highways, railways, water conservancy, and cavern storage facilities. With cutting-edge intelligent technology, Wuxin Equipment is redefining the benchmarks for tunnel construction efficiency and safety.

L0 Electronic Control Version

It comes standard with intelligent angle adjustment, drilling logs, data storage and upload, and voice-activated fault alerts. Electric proportional remote control ensures simple, intuitive operation. The drill arm features an intelligent angle display on the thrust beam for easy positioning. Integrated automatic drill bit anti-jamming functionality minimizes tool wear. Drilling logs, data storage and upload, and voice-activated fault alerts facilitate equipment monitoring.

L1 Semi-Computerized Version

Upgraded from the L0 configuration with automatic body positioning, drilling plan visualization, and real-time parameter acquisition. Equipped with a body positioning system for automatic body alignment, enabling precise hole placement by importing sectional hole layout diagrams. Visualized drilling angles with automatic beam leveling. Automatically collects and stores construction logs, drilling records, and real-time data, directly connecting to the construction unit's management platform.

L2 Full PC Version

Upgraded from the L1 model with enhanced automatic hole-finding and drilling capabilities, MWD geological analysis, 3D contour scanning, collision avoidance alerts, personnel intrusion protection, and self-diagnostic functions. The automatic hole-finding and drilling feature enables drilling according to predefined hole layouts. The MWD system provides real-time rock formation analysis for advance geological forecasting and optimized drilling plans. 3D contour scanning enables precise detection of over-excavation and under-excavation. Boom collision avoidance and personnel intrusion protection ensure comprehensive construction safety. The self-diagnostic function provides automatic fault alerts and pinpoints malfunctions, facilitating rapid troubleshooting and maintenance.

Both the Uniroc three-arm computerized face drill rig and the double-curved-arm computerized rock drilling rig can be configured with L0, L1, or L2 drilling control systems to meet diverse construction requirements. Equipped with Wuxin Equipment's self-developed Uniroc brand hydraulic rock drills, these rigs achieve a maximum drilling speed of 3 meters per minute, delivering high rock drilling efficiency with stable and reliable performance.

L2 Full PC Version --Face Drill Rig Construction Process

Smart Planning

Based on comprehensive geological reports, real-time drilling data, and face conditions, the system intelligently identifies surrounding rock conditions, automatically generates drilling and blasting plans along with blast hole layouts, and imports them into the equipment.

Automatic Vehicle Positioning

By scanning the reference points preset on the initial cross-section, the equipment automatically calculates and precisely locates.

Automatic Drilling

The equipment automatically drills holes according to a preset drilling outline, requiring only monitoring and assistance from the operator. The double-curved arm computerized rock drilling rig adapts to invert arch operations, reducing over-excavation in the invert arch.

Cross-section and 3D contour scanning

After completing blasting operations and removing debris to eliminate hazards, utilize 3D contour scanning to generate point cloud data and models of the excavation surface. Precisely compare these against the design cross-section to control over-excavation and under-excavation.

Dynamic Optimization

The equipment can be optionally equipped with an automatic rod-on-bore function for drilling advance holes (depth 30 meters). The MWD (Measurement While Drilling) system analyzes rock formations to generate geological maps and reports, dynamically optimizing blasting parameters for the next cycle to achieve dynamic design.

The Uniroc fully computerized face drill rig integrates construction log recording, automatic drilling data collection, real-time transmission and storage of drilling data, intelligent identification of surrounding rock at the working face, automatic generation of blast hole diagrams, autonomous equipment positioning, automated drilling, and automatic rock drilling for invert arches. These capabilities significantly enhance the automation and intelligence of tunnel rock drilling operations, effectively controlling over-excavation and under-excavation, reduces reliance on operator skill, and substantially enhances construction safety. This drives the transformation of tunnel construction toward a model of “mechanization replacing manual labor, automation reducing personnel, and intelligence achieving unmanned operation.” Wuxin Equipment makes tunnel construction safer, more economical, and more efficient!
