Vibroflotation method for forming gravel pile with effective pile diameter
The vibroflotation method for forming the gravel pile with the effective pile diameter comprises the steps that self-adaptive control is conducted on launching of a vibroflotation gravel pile machine, and gravel pile hole construction is rapidly completed; the gravel filler is placed in the gravel pile hole, and the vibroflot conducts vibroflot densification on the gravel filler around the vibroflot; when the vibroflot carries out vibroflot encryption on the surrounding gravel filler, a flow velocity sensor arranged in the vibroflot generates a real-time electric signal corresponding to the amplitude of the vibroflot; and according to the real-time electric signal generated by a flow velocity sensor arranged in the vibroflot, vibroflot encryption of the vibroflot is controlled, so that the pile diameter of the gravel pile formed by the gravel filler filled in the gravel pile hole is equal to the effective pile diameter. According to the method, the supply amount of the water pressure is accurately controlled according to the compactness of different stratums, frequent adjustment of the pore forming speed is avoided, vibro-replacement construction is accelerated, and the gravel pile formed by vibro-replacement gravel filler is tightly combined with the soil layer.
本发明公开一种形成有效桩径碎石桩的振冲方法，包括：通过对振冲碎石桩机下水进行自适应控制，快速完成碎石桩孔施工；将碎石填料置入碎石桩孔中，使振冲器对其周围的碎石填料进行振冲加密；在所述振冲器对其周围碎石填料进行振冲加密期间，设置在振冲器内的流速传感器生成对应于振冲器振幅的实时电信号；根据设置在振冲器内的流速传感器生成的所述实时电信号，对所述振冲器的振冲加密进行控制，使填入碎石桩孔中的碎石填料形成碎石桩的桩径等于有效桩径。本发明方法，根据不同地层密实度精确控制下水压力的供给量，避免造孔速度频繁调整，使振冲施工加速进行，并使振冲碎石填料形成的碎石桩与土层紧密结合在一起。
