Product details
I. Core Functions and Structures
1. Rotary Drilling Mechanism
Both models achieve drilling through low-speed rotating drill rods equipped with external spiral blades. These blades utilize their wedge-shaped design to transport excavated materials (e.g., soil, clay, shallow weathered rock) upward. Some variants feature hollow drill rods for simultaneous collection of undisturbed samples.
2. Power Drive Methods
• Mechanical/Hydraulic Drive: Provides drilling power via mechanical pressure or hydraulic systems, adapting to diverse operational conditions.
• Modular Design: Drill rods, bits, and other components support rapid replacement, enabling customized configurations (e.g., corrosion-resistant parts, plug-in flanges) for enhanced versatility.
II. Technical Parameter Comparison
【表格】
Parameter ET40 Auger Drill ET80 Auger Drill
Borehole Diameter 25mm to 400mm (varies by model) Covers ET40 range; may support larger diameters
Drilling Depth 0.6m to 40m (shallower for handheld units) Deeper drilling capacity for large-scale projects
Power Source Handheld, small pneumatic (e.g., coal sampling) Vehicle-mounted (e.g., truck-installed), hydraulic systems
Typical Applications Soil sampling, small pile holes, shallow geological surveys Large pile foundations, deep sampling, engineering geological investigations
III. Application Scenarios
1. ET40 Auger Drill
• Geological Sampling: Coal sampling, soil stratification analysis.
• Small-Scale Projects: Fence installation, tree-planting holes.
• Limitations: Unsuitable for loose sand/gravel layers, high-moisture environments, or hard rock formations.
2. ET80 Auger Drill
• Infrastructure: High-speed rail bridge piles, photovoltaic power station foundations.
• Resource Development: Mineral exploration, groundwater monitoring wells.
• Advantages: Efficient drilling in deep, hard soil layers; supports large-diameter boreholes.
IV. Selection Guidelines
1. Based on Project Scale
• Small Projects(e.g., residential foundations, agricultural irrigation): Prioritize ET40 for cost efficiency and maneuverability.
• Large Projects(e.g., commercial buildings, industrial facilities): Opt for ET80 to meet high-load, deep-drilling demands.
2. Based on Geological Conditions
• Soft Soil/Clay Layers: Both models are viable, but ET80 offers higher efficiency.
• Hard Rock/Sand-Gravel Layers: Verify torque specifications; consider specialized hard-rock drills if needed.
3. Budget and Maintenance
• ET40: Lower initial cost and simpler maintenance, ideal for budget-constrained or short-term use.
• ET80: Lower long-term cost per use but requires skilled operators and regular upkeep.
V. Operational Precautions
1. Safety Protocols
• Avoid overloading to prevent drill rod fractures or equipment tipping.
• Maintain steady pressure during drilling; prevent sudden starts/stops to avoid bit jamming.
2. Maintenance
• Regularly inspect hydraulic fluid levels and filters to ensure cleanliness.
• Replace worn drill rods promptly to prevent blade detachment and accidents.
3. Environmental Adaptation
• Humid Conditions: Strengthen electrical component protection against short circuits.
• Low Temperatures: Preheat hydraulic systems before operation to avoid excessive oil viscosity.
