The invention discloses an ultra-deep vibro-replacement gravel pile construction method under an ultra-deep covering layer of an ultra-strong seismic zone. The method comprises the steps that a first detection element used for detecting mast deflection parameters is installed in a mast; a second detection element used for detecting deflection parameters of the vibroflot is installed on the shock absorber; when the vibroflot is used for carrying out vibroflot construction on the stratum, whether the perpendicularity of the vibroflot meets the requirement or not is analyzed according to the detected mast deflection parameters and vibroflot deflection parameters; and if the perpendicularity of the vibroflot does not meet the requirement, the reason for deflection of the vibroflot is analyzed, and the mast and/or the vibroflot are/is controlled according to the analysis result, so that the vibroflot conducts vibroflot construction with the perpendicularity meeting the requirement, and the vibroflot gravel pile with the effective pile diameter is formed. According to the method, the vibroflot can accelerate vibroflot construction on the deep and thick covering layer stratum with the thickness being 50 m or above according to the stratum condition and the perpendicularity meeting the requirement, and the gravel pile formed by vibroflot gravel filler is tightly combined with the soil layer.
本发明公开了一种超强地震带超深覆盖层下超深振冲碎石桩施工方法，包括：将用于检测桅杆偏斜参数的第一检测元件安装在桅杆内；将用于检测振冲器偏斜参数的第二检测元件安装在减震器上；利用振冲器对地层进行振冲施工时，根据检测到的桅杆偏斜参数和振冲器偏斜参数分析振冲器的垂直度是否符合要求；若振冲器垂直度不符合要求，分析使振冲器产生偏斜的原因，并根据分析结果对桅杆和/或振冲器进行控制，以便振冲器以符合要求的垂直度进行振冲施工，形成具有有效桩径的振冲碎石桩。本发明方法，使振冲器能根据地层条件及符合要求的垂直度对50m以上深厚覆盖层地层加速振冲施工，并使振冲碎石填料形成的碎石桩与土层紧密结合在一起。
