Pile body forming method in vibro-replacement stone pile machine construction

The invention discloses a pile body forming method in vibro-replacement stone pile machine construction. The pile body forming method comprises the steps that the charge level depth in a pile hole formed through construction before stone is put in is obtained; stone is put into the pile hole subjected to charge level depth measurement, and a section of loose pile body is formed; the charge level depth of the formed loose pile body is measured and calculated, and the average filling amount of the loose pile body per linear meter is calculated according to the obtained height difference of the charge level depth before and after stone feeding; carrying out vibroflotation densification construction on the loose pile body to form a dense pile body; calculating the average pile diameter per linear meter of the dense pile body by using the average filling amount and the density coefficient; and the vibro-replacement parameters of the vibro-replacement gravel pile machine are adjusted according to the comparison res
