The soil testing machine
This particular machine is operated hydraulically ... other types are rotary (more like drilling). This one bangs the rods in.
One part of the test removes cores of soil to test for any contaminants there might be, plus the general soil type and what different layers there might be. Another test is done by banging rods in to test the density of the soil ... that one is done by seeing how many "bangs" it takes to push each rod a set depth.
This machine could go down 29Soil testing ... each rod was a metre in length. I did not see the entire operation, but there were at least 5 rods down there ... possibly more. This part of the process was for testing the soil density by seeing how many "hits" were needed to push the rods to certain depths.
This machine could go down 20 metres, although they did not go that deep today.
