This afternoon, we researched and designed a simple boring tool for making
holes into the soil where we need to insert temperature sensors in and
around the Energy Modules.
We used a 32mm diameter plastic pipe, a metre long, and took 4 6-inch nails
and fixed them to the end, with about an inch sticking proud out the end.
Then the plastic tube was connected to our powerful vacuum cleaner and
managed to “drill” down into the sandy soil!
We did hit the gravel interface which was hard to get pass, but we did
managed to get down 1 metre.
But the pipe did clog up with the damp sand so we will have to clean it out
regularly, but fortunately, we have only 35 holes to drill!!
