The invention discloses a filling and pile-forming method of a vibro-replacement gravel pile machine for an ultra-deep covering layer of an ultra-strong seismic zone, which comprises the following steps of: carrying out rapid vibro-replacement hole-forming construction on a stratum through a vibro-replacement device and water, and forming a gravel pile hole; before gravel filler is put into the gravel pile hole, the initial charge level height of the gravel pile hole is detected through electric waves; after the initial charge level height is obtained, the gravel filler is accurately placed into the gravel pile hole through a loader to form a section of loose pile body, and the charge level height of the loose pile body is detected; and the height of the loose pile body is determined according to the height of the charge level of the loose pile body and the initial charge level, so that the pile diameter of a gravel pile section formed by vibroflotation and densification of the loose pile body through the vibroflotation device is calculated. According to the method, the height of the charge level before and after vibroflotation densification construction can be rapidly and accurately measured, throwing of the gravel filler is accurately completed, it is ensured that the weight of the gravel filler adopted for forming the gravel pile meets the requirement, the water pressure can be accurately controlled according to the vibroflotation speed and the stratum compactness, and smooth vibroflotation construction is ensured.
本发明公开一种超强地震带超深覆盖层振冲碎石桩机填料成桩的方法，包括：通过振冲器和下水对地层进行快速振冲造孔施工，形成碎石桩孔；在向碎石桩孔投放碎石填料之前，通过电波检测碎石桩孔的初始料面高度；获得初始料面高度后，通过装载机将碎石填料精准置入碎石桩孔内形成一段松散桩体，并检测松散桩体料面高度；通过松散桩体料面高度和初始料面高度，确定松散桩体高度，以便计算振冲器对松散桩体进行振冲加密所形成的碎石桩段的桩径。本发明方法，可对振冲加密施工前后的料面高度快速、准确测量，精准完成碎石填料的投放，确保形成碎石桩采用的碎石填料重量符合要求，且可根据振冲速度和地层密实度精确控制下水压力，确保振冲施工顺利进行。
