Method for predicting shape of underground gravel pile
The invention discloses a method for predicting the shape of an underground gravel pile, and the method comprises the steps: respectively drilling holes around a planned gravel pile, forming a plurality of measurement holes for measuring the shape of the gravel pile, and hoisting a pressure sensor assembly in each measurement hole; the vibroflotation construction of a gravel pile hole is carried out by controlling the water-air linkage of a vibroflotation gravel pile machine comprising a telescopic guide rod and a vibroflotation device; in the vibroflotation construction period of the gravel pile hole, the pressure sensor assembly in each measuring hole around the gravel pile hole and the vibroflotation device move downwards synchronously, and a vibroflotation signal transmitted by the vibroflotation device vibroflotation soil layer is detected; and according to a vibroflotation signal detected by the pressure sensor assembly in each measuring hole and the predicted average pile diameter of the gravel pile, the shape of each gravel pile section formed by densifying the gravel pile filler through the vibroflotation device is predicted.
本发明公开了一种预测地下碎石桩形状的方法，包括：通过在规划的碎石桩的周围分别钻孔，形成多个用于测量碎石桩形状的测量孔，每个测量孔中吊装压力传感器组件；通过对包括伸缩导杆和振冲器的振冲碎石桩机的水气联动进行控制，进行碎石桩孔的振冲施工；在进行碎石桩孔的振冲施工期间，碎石桩孔周围的每个测量孔中的压力传感器组件与振冲器同步下移，检测振冲器振冲土层传导的振冲信号；根据每个测量孔中的压力传感器组件检测的振冲信号以及预测的碎石桩的平均桩径，预测振冲器在后加密碎石桩填料而形成的每个碎石桩段的形状。
