Method for forming vibro-replacement gravel pile with effective pile diameter under ultra-strong seismic zone
The invention discloses a method for forming a vibro-replacement gravel pile with an effective pile diameter under an ultra-strong seismic zone, which comprises the following steps of: after forming a gravel pile hole, arranging a filling device with a weighing element at an orifice of the gravel pile hole, and aligning a feeding port of the filling device to the orifice; the gravel filler is placed into a filler device with a weighing element through a loading machine, and the weight of the gravel filler is obtained and stored; the gravel filler with the obtained weight is put into a gravel pile hole, and a vibroflot is used for conducting vibroflot densification construction on the gravel filler; during construction, vibro-replacement compaction of the vibro-replacement device is controlled through a method of detecting the amplitude of the vibro-replacement device through the flow speed, and the vibro-replacement gravel pile with the effective pile diameter is formed. According to the method, rapid vibroflotation pore-forming can be carried out according to stratum conditions, weight measurement and throwing of the gravel filler are accurately completed, it is ensured that the weight of the gravel filler thrown into a gravel pile hole meets the requirement, the formed gravel pile can be tightly combined with a surrounding soil layer, and the pile diameter of the gravel pile truly meets the design requirement.
本发明公开一种超强地震带下形成有效桩径振冲碎石桩的方法，包括：形成碎石桩孔后，将具有称重元件的填料装置安置于碎石桩孔的孔口处，并使填料装置的投料口对准孔口；通过装载机将碎石填料置入具有称重元件的填料装置内，获得并保存碎石填料的重量；将获得重量的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；施工期间，通过流速检测振冲器振幅的方法对振冲器的振冲加密进行控制，形成具有有效桩径的振冲碎石桩。本发明方法，能根据地层条件进行快速振冲造孔，并精准完成碎石填料的测重与投放，确保投放到碎石桩孔内碎石填料重量符合要求，且能够使形成的碎石桩与周围土层紧密结合在一起，使碎石桩的桩径真正达到设计要求。
