Drainage saturation reduction pile suitable for near-water foundation pit excavation and using method of drainage saturation reduction pile
A drainage saturation reduction pile suitable for excavation of a waterside foundation pit comprises a round pipe pile and a round head pile tip arranged at the bottom of the round pipe pile, annular electrode plates are arranged on the side wall of a pile body of the round pipe pile at intervals in the vertical direction, an underground water monitor is installed between every two adjacent annular electrode plates, and a wire conduit and an inflation pipe are preset in the round pipe pile; the annular electrode plate and the underground water monitor are connected with a ground control system through wire conduits, and the inflation pipe is connected with the ground control system and an air injection hole in the side portion of the round head pile tip. On the basis that pile position arrangement is combined with a dewatering funnel formed by foundation pit dewatering, upper electrolysis desaturation, bottom inflation desaturation and side wall drainage and drainage combined treatment is carried out, and the stability and the liquefaction resistance of a peripheral soil body in the excavation process of the near-water foundation pit are effectively improved; meanwhile, due to the environmental protection property of the desaturation treatment and the recoverability of the pile body material of the steel pipe pile, the defects of high cost and high pollution of the traditional mixing pile and grouting construction method are avoided.
一种适用于临水基坑开挖的排水减饱和桩，包括圆管桩和设置在圆管桩底部的圆头桩尖，所述圆管桩桩身侧壁沿竖向间隔布置环形电极板，相邻环形电极板之间安装地下水监测器，所述圆管桩内预设导线管和充气管，所述环形电极板和地下水监测器均通过导线管与地面控制系统相连，所述充气管分别连接地面控制系统和圆头桩尖侧部的注气孔。本发明在将桩位布置同基坑降水形成的降水漏斗结合的基础上，开展上部电解减饱和、底部充气减饱和、侧壁疏排水联合处理，有效提升了临水基坑开挖过程中周边土体的稳定性和抗液化能力；同时，减饱和处理自身的环保性与钢管桩桩身材料的可回收性，规避了传统搅拌桩、注浆工法的高成本、高污染的缺点。
