Vibroflotation construction method of self-adaptive gravel pile hole
The invention discloses a self-adaptive gravel pile hole vibroflotation construction method which comprises the following steps: a pipeline for supplying water penetrates through a telescopic guide rod and a vibroflotation device and then extends out from the bottom end of the vibroflotation device, so that the water is sprayed out from the bottom end of the vibroflotation device to carry out water flotation pre-destruction on a stratum; when it is judged that the current pore-forming speed of the vibroflot is smaller than the highest pore-forming speed and larger than the lowest pore-forming speed, the pore-forming speed change trend of the vibroflot is determined according to the current pore-forming speed of the vibroflot; and according to the determined change trend of the pore-forming speed of the vibroflot, controlling the flow of water sprayed from the bottom end of the vibroflot, so that the pore-forming speed of the vibroflot is kept in a proper speed interval and is always lower than the highest pore-forming speed.
本发明公开了一种自适应碎石桩桩孔的振冲施工方法，包括：将用于供应下水的管道穿过伸缩导杆和振冲器后从振冲器的底端伸出，以便下水从振冲器底端喷出对地层进行水冲预破坏；在判断振冲器当前造孔速度小于最高造孔速度且大于最低造孔速度时，根据振冲器当前造孔速度，确定所述振冲器造孔速度变化趋势；根据所确定的振冲器造孔速度变化趋势，控制从振冲器底端喷出的下水的流量，使振冲器造孔速度保持在一个合适的速度区间，并始终低于最高造孔速度。
