Weather: Rain in the morning followed by a mostly cloudy afternoon. The cold front moving through has been a fantastic reprieve from the heat.
On Tuesday we installed and performed a pull test on the standard and auger screw anchors in various configurations. All failed the 20 meter tower test by pulling out of the soil under the required force threshold specified by the manufacturer. We are unable to drive the anchors deeper due to drainage tiles throughout both the fields and swale.
We settled on sourcing one ton 2'x2'x3' concrete blocks to use as anchor points for the guy wires of the 20 meter towers. Ken(the landowner) has been extremely accommodation, letting us use both his trailer and backhoe to move them. Tomorrow we plan on installing blocks at the anchor locations for both 20m towers. After this, install will proceed as planned.
