C.2, when H < construction depth≤target depth, vibrating impacter central water spray pipe and side spray water pipe standard-sized sheet, guide side sparge pipe
Aperture is 10%-50%.
10. vibroflotation pile construction method according to claim 9, it is characterised in that: in the step D vibrating impacter sparge pipe and
The unlatching of guide rod sparge pipe is divided into two kinds of situations:
D.1, when H < construction depth≤target depth, vibrating impacter central water spray pipe and side spray water pipe aperture are 10%-50%,
Guide side sparge pipe standard-sized sheet；
D.2, as construction depth≤H, vibrating impacter central water spray pipe and side spray water pipe standard-sized sheet, guide side sparge pipe are closed.
