Pile extracting construction method
The invention discloses a pile extracting construction method, wherein an approximate location of a discarded pile is initially determined by using a seismic geophysical survey, and the specific pile location is detected and determined by using a small screw drill; by using the method, the discarded pile is located more accurately; during a steel pipe sinking procedure, a soil layer beside the pile is washed in a casing pipe by using high pressure jetted gas and water, so that the frictional force on the outer side of the pile is reduced to be minimum, and the pile is convenient to pull out; compared with the traditional method, the pile extracting method is fast in progress; the new foundation bearing capacity in a later period is also ensured.
