Ultra-deep vibroflotation pile construction method
The invention discloses a ultra-deep vibroflotation pile construction method. The ultra-deep vibroflotation pile construction method is charactized in that a backfill layer and a hard layer are penetrated through pile casing placement as well as rotary excavating hole guiding, hole collapse of the backfill layer during direct hole forming of vibroflotation equipment is avoided, then an upper guiderod is rapidly inserted and additionally arranged in a guide rod butt joint mode, so that the length of the whole guide rod is increased, and a bottom guide rod assembly suspends a vibroflot to continue hole forming to a target depth. According to the construction method, through a guide rod butt joint mode, the upper guide rod is additionally arranged in a rapid insertion mode, the length of thewhole guide rod is increased, formed holes of the vibroflot hung on the bottom guide rod assembly can easily reach the target depth, and therefore the construction quality, efficiency, economical efficiency and convenience all meet the design requirements.
本发明提供一种超深振冲桩施工方法，通过下护筒，旋挖引孔的方式穿过回填层和硬层，避免振冲设备直接造孔时回填层塌孔，再通过导杆对接的方式，快速插接增设上导杆，延长整个导杆的长度，使底部导杆组件悬挂振冲器继续造孔至目标深度。本发明通过导杆对接的方式，快速插接增设上导杆，延长整个导杆的长度，使底部导杆组件悬挂振冲器造孔轻松达到目标深度，施工质量、效率、经济性、便利性均达到设计要求。
