In infrastructure projects, working in complex geological formations remains a core challenge for construction teams. This is particularly true for formations containing floating, pebble, and gravel layers, as well as those covered by fractured, strongly weathered rock. Traditional drilling rigs often struggle with low penetration efficiency and poor borehole quality in such environments. The Sichuan Drill God ZML160 Multi-Function Crawler Drill, leveraging its core advantages of “high-efficiency penetration through complex strata” and “one machine for multiple scenarios,” has distinguished itself in numerous key projects, becoming the preferred equipment for geotechnical anchoring works.
Project Case: Practical Application in Advance Support for Yifu High-Speed Rail Tunnel
A section of the Yifu High-Speed Rail tunnel project traverses fractured, strongly weathered rock formations with poor surrounding rock stability. Advance pipe arch support and exploratory drilling were required, demanding the drill rig to perform deep-hole pipe-following drilling within confined tunnel spaces while ensuring borehole accuracy and construction safety. Previously, the construction team used conventional drilling rigs, which suffered from slow drilling efficiency due to complex strata and frequent borehole wall collapses, severely impacting the schedule. The introduction of the Sichuan Drill God ZML160 achieved a quantum leap in construction efficiency. Equipped with a high-power hydraulic system and intelligent feed mechanism, this rig employs a “pipe-following drilling + graded wall protection” technique for fractured rock formations. Combined with high-strength alloy drill bits, single-hole drilling efficiency surged to over three times that of conventional equipment. Simultaneously, its tracked chassis design ensures agile maneuverability within the tunnel's confined space, enabling precise hole positioning with borehole verticality error controlled within 0.5%. This meets the stringent requirements for pipe arch support. Ultimately, the tunnel's advance support project was completed 15 days ahead of schedule, with construction costs reduced by 20%, earning high praise from the project owner.
Core Advantages: Multi-scenario Adaptability and Complex Formation Penetration
The ZML160's competitive edge stems from its “multi-functional, highly adaptable, and efficient” product characteristics. Functionally integrated, it excels not only in specialized tunnel tasks like advance borehole drilling, core sampling, and anchoring, but also serves over 10 engineering scenarios including power plant slope stabilization, highway subgrade reinforcement, foundation uplift anchor bolts, and mining blast holes. This true “one machine, multiple functions” capability enables immediate deployment upon relocation, significantly reducing contractors' equipment investment costs.
For complex formations, the ZML160's deep-hole casing-assisted drilling technology stands out. Its dual-power-head design effortlessly handles impact loads in sandy, gravelly, and cobble formations. Equipped with an automatic feed-and-retraction system, it dynamically adjusts drilling parameters based on formation hardness, preventing jams and drill bit entrapment. During a dam seepage control project at a hydropower station, this rig successfully drilled 50-meter-deep drainage holes in gravel formations exceeding 30cm in particle size, achieving a 100% hole completion rate and demonstrating exceptional adaptability to diverse geological conditions.
Customized Technical Solutions: Precisely Tailored to Project Requirements
Sichuan Drill God provides the ZML160 with a dedicated technical solutions service team, offering customized solutions based on varying geological conditions and construction requirements. Additionally, the ZML160 can be customized with an intelligent monitoring system that collects real-time data on drilling speed, torque, and hole depth. This enables visual management of the construction process via a remote platform, facilitating progress and quality control for project owners. Its modular design also simplifies maintenance, allowing quick disassembly and replacement of key components to minimize equipment downtime.
From the Yifu high-speed railway to hydroelectric dams, and from slope stabilization to foundation pit projects, the Sichuan Drill God ZML160 multi-functional drill rig consistently delivers robust support for complex geological construction with its “high efficiency, reliability, and flexibility.” Against the backdrop of high-quality development in the infrastructure industry, it will continue to drive technological innovation, emerging as a “powerful tool for tackling tough challenges” in an increasing number of projects.
