For determining the resistance of different soil
strata to dynamic penetration of a 50 mm cone and thereby obtain an
indication regarding their relative strengths or density or both. The method
helps survey of large area in a short time. In some cases, especially if the
depth is great, it may be difficult to pull out the cone after the
completion of the test. Hence the cone without threads should be used in the
case of deep soundings as it may be left in the ground. For shallow depths,
generally up to 15 m, if the conditions permit, the cone with threads may be
used.
It consists of following
- Cone Plain 50mm base dia and cone angle 60 deg.
- Cone adaptor with cone and standard threads for 'A' rod coupling.
- Cone threaded for 'A' rod coupling 60 deg. cone angles, 50mm base
dia.
