Vibroflotation method capable of ensuring effective pile diameter of gravel pile
The vibroflotation method capable of ensuring the effective pile diameter of the gravel pile 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; in the vibroflotation encryption period, a sound pickup arranged on the inner side of a vibroflotation device shell is used for detecting real-time vibration signals of the vibroflotation device when the vibroflotation device carries out vibroflotation on gravel embedded into a soil layer around a gravel pile hole; and according to the real-time vibration signal of the vibroflot, vibroflot of the vibroflot on the gravel pile is controlled, so that the vibroflot vibroflots gravel filled into the gravel pile hole, and the pile diameter of the gravel pile 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.
本发明公开一种可确保碎石桩有效桩径的振冲方法，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；在振冲加密期间，利用设置在振冲器壳体内侧的拾音器检测振冲器对嵌入到碎石桩孔周围土层中的碎石进行振冲时的振冲器实时振动信号；根据所述振冲器实时振动信号，对所述振冲器对碎石桩的振冲进行控制，使振冲器振冲填入碎石桩孔中的碎石而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。
