MetaDrill’s automatic SPT hammer boosts drilling efficiency with precision and reliability. We follow strict SOPs and regular calibration to ensure accurate geotechnical test results.
What is an Automatic SPT Hammer?
A standard penetration test (SPT) is a necessary site test during geotechnical exploration to help determine soil parameters. In the past, SPT was done with manual or semi-automatic hammers, creating variations in energy transfer. The automatic SPT hammer, nevertheless, automates energy transfer such that it is executed evenly and accurately.
MetaDrill's automated SPT hammer reduces the potential for human error, streamlines the testing process, and optimizes overall drilling efficiency. By adding this equipment to our Geotech drill rig fleet, we offer unprecedented reliability with all geotechnical investigations.
Standard Operating Procedures for Conducting SPT Tests
To obtain meaningful data from an SPT, it is essential to follow strict standard operating procedures (SOPs). Here are the key steps involved:
Drill to the Test Depth: Using a geotechnical drilling rig, bore a hole to the required depth.
Set the Sampler: Lower the standard split-spoon sampler to the test depth.
Apply the Hammer: Use the SPT system to drive the sampler into the soil, recording the number of blows required for each 6-inch increment until 18 inches of penetration are achieved.
Record the Blow Count: The sum of the last two increments gives the N-value, which is crucial for soil strength analysis.
Maintain Equipment Integrity: Frequent maintenance of the compact drill rig and hammer is essential to provide consistent results.
Adhering to these SOPs ensures that the SPT results are reproducible, comparable, and reliable across various sites and conditions. MetaDrill insists on strict compliance with these protocols in all our projects.
Why is an Automatic SPT Hammer a Game-Changer?
When using a manual system, variations in operator technique can lead to inconsistent energy application, affecting the test results. Our automated SPT hammer eliminates these variables by delivering a uniform energy output every time.
Here is why an automated SPT hammer is crucial for drilling efficiency:
Consistency: The machine process ensures that the same level of energy is transferred with every strike, and this enhances the data consistency acquired.
Speed: Conserves time to conduct SPTs, allowing more tests to be conducted daily.
Safety: Avoids operator injury or fatigue, improving work environment safety on geotechnical drill rigs.
Cost-Effectiveness: Quick testing means lower labor charges and faster project completion.
Excellence is our policy, and this is reflected in our fitting out all our affordable geotechnical drill rigs with high-tech hammers.
Importance of Regular Calibration
Even the most advanced SPT hammer can drift out of specification over time. Regular calibration ensures the hammer continues to deliver the correct energy levels needed for accurate SPT results.
Benefits of calibration include:
Precision: Calibration guarantees the hammer is operating within specified energy delivery tolerances.
Compliance: Meets industry standards and client specifications for geotechnical reports.
Data Integrity: Accurate energy measurements lead to better soil profiling and foundation design.
We use certified calibration facilities and maintain detailed records to ensure transparency and trust in our results.
