SmartPT SPT Shahmerdan Energy Efficiency Measurement System

SMARTPT Why?

Soil mechanics – the SPT field test is frequently used in basic engineering applications. The obtained SPT blow counts are corrected by considering the energy differences in the hammer system used. A local SPT hammer monitoring device has been developed by Geodestek R&D engineers operating within the METU Technopolis using domestic resources. With the use of this device, uncertainties reaching up to two orders of magnitude in the obtained blow counts have been eliminated. Geodestek, with the SPT hammer energy monitoring device, can accurately measure and report the energy efficiency of any type of SPT hammer system within minutes, depending on the preference of geotechnical service providers, either from its central office or on-site.

5 Valid Reasons to Measure Energy Efficiency with SPT Şahmerdan

• Turkey Building Earthquake Regulation (2019); energy correction C according to the type of hammer based on the number of blows obtained from standard penetration tests._AND It provides an approximate range for determining the factor. This range shows almost double variations even for the automatic torque wrench type.

• The final report of the Ministry of Transport and Infrastructure of the Republic of Turkey, General Directorate of Highways, Directorate of Art Structures, on the preparation of earthquake regulations for transportation and distribution facilities (2020) recommends the use of a calibrated plumb bob system for the selection of engineering parameters essential for design.

• According to ASTM D 6066, it is necessary to know the energy efficiency of the hammer based on measurements taken from each site where liquefaction triggering analyses are conducted.

• Even if your drill is automatic, the energy efficiencies obtained with different automatic drill systems are significantly affected by factors such as the assembly and operation details, usage conditions and frequency, and the connection and orientation details of the drill – head – rod – sampler system.

• One of the most commonly used field tests, the standard penetration test, makes it an inevitable reality to have a system of a chessman that you can measure its efficiency and periodically check for the correct selection of parameters that will illuminate your engineering designs.
