Method for forming permeable vibro-replacement gravel pile under ultra-deep covering layer of ultra-strong seismic zone
The invention discloses a method for forming a permeable vibro-replacement gravel pile under an ultra-deep covering layer of an ultra-strong seismic zone. The method comprises the steps that vibro-replacement construction of gravel pile holes is rapidly completed; detecting the density of slurry in the gravel pile hole through an ultrasonic device to obtain the density information of the slurry in the gravel pile hole in the period of cleaning the gravel pile hole formed by the rapid vibroflotation pore-forming construction; according to the density information of the slurry in the gravel pile hole, controlling the lower water flow of supplied lower water and the lower gas flow of supplied pressure lower gas, so that the density of the slurry in the gravel pile hole meets the requirement; and after hole cleaning treatment is completed according to the slurry density meeting the requirement, gravel filler is put into the gravel pile hole, a vibroflot is used for conducting vibroflot densification construction on the gravel filler, and the vibroflot gravel pile with the effective pile diameter is formed. According to the method, it is ensured that the water permeability in the gravel pile hole meets the preset requirement, so that it is ensured that the water permeability of the ultra-deep vibro-replacement gravel filler pile formed under the ultra-deep covering layer of the ultra-strong seismic zone is good.
本发明公开一种超强地震带超深覆盖层下形成透水振冲碎石桩的方法，包括：快速完成碎石桩孔的振冲施工；在对快速振冲造孔施工形成的碎石桩孔进行清孔处理期间，通过超声波装置检测碎石桩孔内泥浆密度，得到碎石桩孔内泥浆密度信息；根据碎石桩孔内泥浆密度信息，对供应下水的下水流量和供压下气的下气流量进行控制，以便碎石桩孔内泥浆密度符合要求；以符合要求的泥浆密度完成清孔处理后，将碎石填料投放到碎石桩孔内，利用振冲器对碎石填料进行振冲加密施工，形成具有有效桩径的振冲碎石桩。本发明方法，确保碎石桩孔内透水性符合预设要求，以便保证在超强地震带超深覆盖层下形成的超深振冲碎石填料桩透水性良好。
