Method for forming anti-sliding vibro-replacement gravel pile under ultra-deep covering layer of ultra-strong seismic zone
The invention discloses a method for forming an anti-sliding vibro-replacement gravel pile under an ultra-deep covering layer of an ultra-strong seismic zone. The method comprises the steps that gravel pile holes are formed; the gravel pile holes are filled with materials, vibroflotation densification construction is conducted, so that vibroflotation gravel piles with the effective pile diameter are formed, and the method comprises the steps that a vibroflotation device conducts vibroflotation densification on gravel materials put into the gravel pile holes located below the slippage layer; a vibroflot carries out vibroflot on the filling materials thrown into the gravel pile holes corresponding to the slippage layer, and the filling materials are vibroflot into the slippage layer around the gravel pile holes; then, the vibroflot carries out vibroflot densification on the gravel filler put into the gravel pile hole, and a slip layer gravel pile section is formed; and the vibroflot continuously carries out vibroflot densification on the gravel filler put into the gravel pile hole. According to the method, it is guaranteed that the ultra-deep vibro-replacement gravel pile formed in the ultra-strong seismic zone is good in water permeability and not dislocated under strong earthquakes, and the safety of the vibro-replacement gravel pile under the strong earthquakes is guaranteed.
本发明公开一种超强地震带超深覆盖层下形成抗滑移振冲碎石桩方法，包括：形成碎石桩孔；向碎石桩孔内填料并进行振冲加密施工，以形成具有有效桩径的振冲碎石桩，包括：振冲器对投放到位于所述滑移层下方的碎石桩孔内的碎石填料进行振冲加密；振冲器对投放到对应于所述滑移层的碎石桩孔内的填充料进行振冲，将所述填充料被振冲到碎石桩孔周围的滑移层中；之后，振冲器对投放到碎石桩孔内的碎石填料进行振冲加密，形成滑移层碎石桩段；振冲器对投放到碎石桩孔内的碎石填料继续进行振冲加密。本发明方法，保证在超强地震带形成的超深振冲碎石桩透水性良好，在强震下不错断，确保强震下振冲碎石桩的安全性。
