Accurate geological data is essential for the design, construction and safety evaluation of all infrastructure projects. With the development of modern engineering towards complexity and diversity, the road construction area expands, the traditional drilling tools gradually fails to satisfy the high-quality exploration requirements in terms of sampling is incomplete, adaptability to terrain is limited, functionality unduly single and testing results are unstable. Under such situation, the core drill has blossomed as a single, professional full matrix solution for geology coring and Standard Penetration Test (SPT) widely used in geotechnical investigation, transportation, water conservancy, municipal building and mineral exploration.

In a single core drill, whole rock, cuttings and soil sampling, geology logging, detection of geological stratification and standardized standard penetration test (SPT) sampling are performed for high-precision subsurface exploration. Using proven dry-hole drilling techniques and specialized tool configurations, the tool recovers undisturbed samples of the subsurface to provide an accurate representation of stratum structure, rock hardness, degree of weathering, and foundation bearing capacity, enabling solutions for geotechnical data important to project design, risk management, and construction verification.

The machinery has excellent terrain adaptability, drilling can be done stably in clay, sand, pebble stratum, weathered stratum and rock stratum. With specially designed sampling barrels and diamond drill bits, it provides full core retrieval in soft ground and fractured hard rock deposits. Different from ordinary drilling machines, it supports direct SPT installation to precisely test soil compactness, bearing capacity and geomechanically indicators, realizing one-stop drilling, sampling and testing and greatly simplifying field exploration procedures.

Built with a high-strength integrated frame and hydraulic leveling system, the core drill delivers high verticality, low vibration and stable operation, effectively avoiding hole deviation and collapse. With trailer mounted and crawler mounted optional configurations, it achieves flexible mobility and rapid on-site transition, adapting to narrow construction areas, scattered survey points and mountainous field conditions. Its simple structure and universal accessories significantly reduce daily maintenance costs and extend service life, ideal for long-term and high-frequency field operations.

Featuring multi-functional integration, high accuracy and low operational cost, the core drill fully meets national exploration standards. It serves a wide range of scenarios including building foundation investigation, traffic infrastructure prospecting, water well drilling and slope treatment, mineral resource exploration and old-site renovation evaluation. As a cost-effective and reliable exploration device, it effectively improves exploration efficiency, guarantees construction safety, and has become the preferred equipment for modern geological survey enterprises.
