What Are The Classifications of Rotary Drilling RIGS

As the core equipment for pile foundation construction, rotary drilling RIGS have various classification methods, and different types are suitable for different geological conditions and engineering requirements. Understanding the classification standards is helpful for the rational selection of equipment and the improvement of construction efficiency. The following are the main classification methods of rotary drilling RIGS:

1. Classified by power type: It is divided into two categories: diesel power and electric power. Diesel-powered drilling RIGS have strong mobility and are suitable for outdoor scenarios without power supply. Electric drilling RIGS are environmentally friendly and energy-saving, with low noise, making them more suitable for urban areas or regions with high environmental protection requirements.

2. Classified by walking mode: It can be divided into tracked type and wheeled type. The crawler drilling rig has a low ground contact pressure and good passability, making it suitable for complex terrains. Wheeled drilling RIGS have a fast moving speed and are easy to transfer to different sites. They are often used in linear projects such as highways and municipal works.

3. Classification by hole diameter: According to the maximum hole diameter, it is divided into small, medium and large. The hole diameter formed by small drilling RIGS is generally less than 1 meter, and they are suitable for construction in shallow or narrow Spaces. The diameter of the holes formed by large drilling RIGS can reach over 3 meters and they are used in deep pile foundation projects.

4. Classified by drilling depth: They are divided into shallow hole drilling RIGS (depth < 30 meters), medium and deep hole drilling RIGS (30-80 meters), and deep hole drilling RIGS (> 80 meters). Shallow-hole drilling RIGS are mostly used in municipal pipeline networks and other projects, while deep-hole drilling RIGS are suitable for deep pile construction in high-rise buildings, Bridges, etc.

5. Classified by drill bit type: Common drill bits include rotary buckets, long spiral drill bits and core drill bits. The rotary bucket is suitable for soil layers such as clay and sand. Long spiral drill bits are used for plain fill soil, silt soil, etc. Core drill bits are targeted at rock strata to achieve hard rock drilling.

6. Classified by driving mode: It is divided into hydraulic drive and mechanical drive. The hydraulic-driven drilling rig has large torque, flexible speed regulation and wide adaptability. The mechanical-driven drilling rig has a simple structure and is convenient to maintain, making it suitable for medium and small-sized projects under conventional geological conditions.

Conclusion: The classification of rotary drilling RIGS is based on multi-dimensional criteria such as power, travel, and hole-forming capacity, and each type has its unique application scenarios. During construction, factors such as geological conditions, project scale and environmental protection requirements should be taken into account to select the appropriate type of drilling rig to achieve efficient and safe pile foundation construction.
