Method for obtaining shape of underground gravel pile
The invention discloses a method for obtaining the shape of an underground gravel pile, which comprises the following steps: controlling the water-air linkage of a vibro-replacement gravel pile machine comprising a telescopic guide rod and a vibro-replacement device to finish the vibro-replacement construction of a gravel pile hole; a plurality of measuring holes are formed in the periphery of the gravel pile, and a pressure sensor assembly synchronously lifted with the vibroflot is hoisted in each measuring hole; the average pile diameter of each gravel pile section is calculated and stored when gravel filler is placed into the gravel pile hole every time and the gravel filler is subjected to vibroflotation and densified through a vibroflotation device to form each gravel pile section; when the vibroflot carries out vibroflot densification on the gravel filler placed in the gravel pile hole every time, the pressure sensor assemblies around the gravel pile hole detect vibroflot signals, transmitted by the vibroflot through a soil layer, of the vibroflot for vibroflot of the gravel pile filler; and according to a vibroflotation signal detected by the pressure sensor assembly in each measuring hole and the average pile diameter of each gravel pile section, the shape of each gravel pile section formed by densifying gravel pile filler through the vibroflotation device is calculated.
本发明公开了一种获取地下碎石桩形状的方法，包括：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，完成碎石桩孔的振冲施工；在碎石桩的周围形成多个测量孔，并在每个测量孔中吊装与振冲器同步提升的压力传感器组件；在每次将碎石填料置入碎石桩孔中，通过振冲器振冲加密碎石填料以形成每个碎石桩段时，计算并保存每个碎石桩段的平均桩径；在振冲器对每次置入碎石桩孔中的碎石填料进行振冲加密期间，碎石桩孔周围的压力传感器组件检测振冲器通过土层传导的振冲碎石桩填料的振冲信号；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每个碎石桩段的平均桩径，计算振冲器加密碎石桩填料而形成的每个碎石桩段的形状。
