In tunnel construction, complex and variable geological conditions pose the greatest challenge to construction. The emergence of the DH180 multi-functional drilling rig, with its precision, efficiency, and versatility, has become the core equipment empowering tunnel construction. From advance exploration drilling to core sampling, from routine operations to emergency rescue, it comprehensively safeguards the safety and progress of tunnel construction.
Advance boreholes serve as the “geological reconnaissance unit” for tunnel construction, directly impacting construction safety. Equipped with intelligent geological identification sensors, the DH180 can detect underground rock layer structures up to 30 meters deep in real time, accurately identifying risks such as karst cavities and water-bearing strata.
Core sampling is crucial for assessing rock mass stability. Leveraging its technological advantages, the DH180 achieves “low-vibration, high-precision” sampling. Utilizing high-strength alloy drill pipes and optimized drilling parameters, it achieves over 90% core integrity in hard limestone formations, providing reliable data support for support design. A tunnel project optimized its support plan based on its sampling results, reducing support costs by 15% while significantly enhancing support structure stability and ensuring subsequent construction safety.
Furthermore, the DH180 demonstrates remarkable adaptability and cost-effectiveness. It integrates foreign precision hydraulic control with domestic equipment's weather resistance, adapting to diverse complex formations like soft soil and fractured rock. Priced at just 60%-70% of comparable imported equipment, it features domestically sourced wear parts and 24-hour after-sales response, substantially reducing construction costs and minimizing project delay risks.
Today, the DH180 has become the “mainstay equipment” for numerous tunnel projects. From the Sichuan-Tibet Railway to the Yibin-Fuling High-Speed Railway, it actively advances the localization of tunnel construction equipment. Demonstrating the robust capabilities of Chinese manufacturing through safety and efficiency, it injects powerful momentum into the high-quality development of tunnel construction.
