Principled very good idea, especially if like us, the woman says to find a new location for the clothes dryer every half year. Execution and handling requires a little practice, but after several attempts it is quite possible the anchor to sink straight. The halt to these anchors are associated with the clothes dryer is still very dependent on the soil conditions and limited use for soft floors (in our mother clay from ca.20cm) after a few weeks with full hanged clothes dryer and some wind has the sleeve enticed and had to be set again.
As I said, if necessary, offer great idea slightly longer version for lighter soils.
