SV Technocrats India’s Core Cutter with Dolly and Rammer is a field testing apparatus used to determine the in-situ dry density of soil, primarily for road and earthwork construction projects. This method is simple, fast, and cost-effective compared to other soil density tests.
Components of the Core Cutter Method
Core Cutter – A cylindrical steel tube (typically 100mm in diameter and 127.3mm in height) used to extract a soil sample from the ground.
Dolly – A metal cap placed on top of the core cutter to protect its edges and ensure uniform distribution of impact force.
Rammer – A hammer-like tool (usually 9 kg weight) used to drive the core cutter into the soil.
Testing Procedure
Preparation of Site – The test area is leveled and cleared of loose soil and debris.
Driving the Core Cutter – The core cutter is placed on the ground with the dolly on top. The rammer is then used to hammer the core cutter into the soil until it is fully embedded.
Extracting the Sample – The cutter is carefully dug out without disturbing the soil inside.
Trimming and Weighing – Excess soil is trimmed off, and the cutter with the soil sample is weighed.
Applications
Used in road construction, embankments, and compacted soil layers.
Helps in determining the compaction quality of soil in the field.
Used in geotechnical and civil engineering projects.
