Automatic Soil Compaction Machine
The Automatic Soil Compactor replaces the hand
compaction procedure as specified for dry density/
moisture content relationship of soil. Both light and heavy
compaction tests can be performed by this machine
using either 100 mm dia or 150 mm dia
compaction moulds. The height of drop of the 50 mm dia
rammer can be set either at 310 mm or 450 mm as per
requirement.
The machine is provided with a standard
rammer weighing 2.6 kg for conducting light
compaction and its weight can be increased to
4.89 kg for heavy compaction test by attaching
additional rod supplied along with it. While using
100 mm dia mould the rammer carriage is
locked in one position and the total area of the mould is
compacted in about 25 strokes.
The number of strokes i.e. 25 can be programmed,
which are digitally displayed. Locking during the course
of test in this stage is through high force solenoids.
A selector switch is provided on the control panel for
selection between 100 mm dia mould or 150 mm dia
mould. For 150 mm dia mould the rammer carriage
shifts radially by 25 mm to give about 8 blows within
the diameter of 100 mm and 17 blows beyond 100
mm dia that is between 100 mm and 150 mm.
This sequence is repeated till the rammer completes
55 blows after which the machine automatically stops.
Safety features like safety lever for preventing rammer
falling when the door is open, total cover for moving
parts, M.C.B. for overload protection are provided as
standard.
