Abstract:
A method of measuring a length of a pile which supports a structure upon the earth comprising:affixing a flexible strand to a first pile segment; driving said first pile segment a desired distance into the earth such that said flexible strand extends along a length of said first pile segment along an exterior surface of said first pile segment; driving a second pile segment into the earth another desired distance such that said second pile segment resides on a top end of said first pile segment, said flexible strand extending along a length of said second pile segment on an exterior surface of said second pile segment; driving a plurality of additional pile segments into the earth such that said plurality of additional pile segments reside upon an end of said second pile segment opposite said first pile segment, said flexible strand extending along a length of said plurality of additional pile segments on an exterior surface of said plurality of additional pile segments; and monitoring a length of said flexible strand during said step of driving said plurality of pile segments, said step of monitoring comprising; monitoring a rate at which said plurality of pile segments are driven into the earth; and comparing the rate at which said plurality of pile segments are driven into the earth with a rate at which said flexible strand moves into the earth.
