THANK
YOU
1.Equipment for the test is assembled.The cone diameter is measured in SI unit.
2.Distance of 3.0m is measured and marked on the rod start from the tip of the cone.
3.The equipment is set up on the ground.
4.The hammer is pilled until it reached the maximum.The hammer is dropped freely to drive the cone into the soil.
a)Collecting a disturbed soil sample for grain-size analysis and soil classification.
b)Determine sub-surface straits graphed and identity materials present.
c)Evaluate soil density and in-situ stress condition.
d)Estimate geotechnical parameters.
ADVANTAGES OF PROBE MACHINTOSH
Soil Investigation is carried out for designing a right type of foundation safely and economically, a designer must possess sufficient information about the physical properties and the arrangement of underlying materials. The field and laboratory investigations required to get this essential information is known as soil exploration.
5.The sum of the number of below for penetration of 3.0m is recorded in the data sheet.
6.The hammer is taken off on the last 0.3 of each road and joined and existing rod with another rod and lastly the hammer.
The below is continued and stoppen when:
a)The below is more than 400 for 0.3m penetration.
b)The depth reached 15m.
