Percussion drilling represents a fundamental and widely-used drilling method in geotechnical and site investigation work, particularly for deep foundation projects where understanding subsurface conditions is critical to foundation design and construction success. Also known as cable percussion drilling or cable tool drilling, ეს ტექნიკა employs a heavy percussion hammer suspended on a steel cable to repeatedly strike and break through soil and rock layers, gradually advancing a borehole to significant depths. მეთოდი რჩება preferred approach for foundation engineering and ground investigation due to its simplicity, cost-effectiveness, and ability to produce disturbed soil and rock samples that accurately represent subsurface stratigraphy across multiple layers and horizons.
