These are not in any order. First steel tubes
approximately 4 inches in diameter are driven
diagonally deep into the ground. They use a huge
drilling device to do this. I have been told the tubes are
driven 70+ feet down. They then insert the rod and a hose
into each tube. The hose is used to pump grout into the tube
thus anchoring the steel rod. Our assumption is that
this whole thing is being done to put a more aesthetically
pleasing face on the steel wall along with adding additional strength.
