The core value of Drillto lies in providing comprehensive trenchless solutions. Through customized products and processes, the company systematically addresses the ten primary construction pain points in the industry, covering the full spectrum of trenchless engineering scenarios:
Overcoming drill-jamming in hard rock: The AT all-strata rock drilling rig features an innovative dual-power-head design. By utilizing the torque and rotational speed of an inner drill rod instead of a traditional mud motor, it eliminates the drawbacks of high energy consumption, costly mud circulation, and environmental concerns. This reduces the cost of drilling consumables, creates a more eco-friendly construction environment, and enhances guidance precision-ensuring success in hard-rock drilling on the very first attempt.
Achieving ultra-high precision in directional drilling: By replacing conventional guidance instruments with laser-based, real-time monitoring technology, this system eliminates signal latency and errors inherent in analog-to-digital conversion. It meets the requirements for ultra-high-precision inclined shaft drilling, enabling standard directional rigs to perform high-precision, multi-angle operations. This empowers clients to undertake major water conservancy, bridge, and tunnel projects while meeting strict directional accuracy standards-as demonstrated by the ultra-high-precision rock anchor hole drilling for the Zhoushan Cross-Sea Bridge, which achieved a final hole accuracy of 0.1%.
Navigating confined urban construction sites: The ZTJN tunnel drilling rig features a compact, lightweight design, addressing the challenges of operating in cramped urban areas or locations with restricted access-such as sites involving utility pipeline upgrades. It is capable of operating within narrow underground shafts and tunnels, making it ideal for urban renewal and utility network renovation projects.
Enabling zero-settlement construction and advanced support: Horizontal auger drilling rigs are designed for projects where ground settlement is strictly prohibited, as well as for high-precision "pipe-roof" (pipe-curtain) pre-support drilling in tunneling-filling a critical gap for specialized construction scenarios.
Integrating directional drilling with core sampling: The directional core-drilling rig combines directional drilling capabilities with high-speed core sampling. This overcomes the limitations of conventional directional rigs-which typically cannot perform high-speed core sampling-thereby facilitating advanced geological exploration.
Mitigating the risk of failure in long-distance crossings: Large-tonnage ZT-series drilling rigs are equipped with patented constant-torque and anti-rebound systems. With significant power redundancy, they effectively handle the challenges of drilling through cobble-rich strata and overcoming high pullback resistance, ensuring that long-distance crossings are completed successfully in a single pass.
Minimize losses from rig downtime: Core components are sourced from leading international brands and integrated with multiple patented protective structures, ensuring equipment stability, durability, and minimal malfunctions. A nationwide 24/7 after-sales support system provides rapid response to resolve issues, thereby reducing downtime-related losses.
Alleviate the pressure of high construction costs and low profit margins: High-efficiency equipment boosts operational productivity; patented designs reduce wear and tear on drilling tools and consumables; and optimized processes lower the likelihood of rework-all of which contribute to improved project profitability.
Reduce the risk of damaging underground utilities: A high-precision guidance system, combined with proven construction techniques, allows for precise control of the drill path, effectively avoiding damage to the dense network of underground utilities often found in older urban areas.
Eliminate risks associated with delayed after-sales support: A nationwide network of service centers, backed by a 24/7 on-call mechanism, ensures a rapid response within 24 hours, safeguarding the project schedule and ensuring timely completion.
