Construction method for pile foundation hole forming in local soft soil layer foundation
The invention discloses a construction method for pile foundation hole forming in a local soft soil layer foundation. The construction method comprises the steps that firstly, the depth position of a local soft soil layer in the foundation is determined; a plurality of hole protection piles are arranged in a local soft soil layer on the outer side of the pile foundation hole site in a driving mode, the upper ends and the lower ends of the hole protection piles extend into stable soil layers above and below the local soft soil layer respectively, the hole protection piles are arranged in a circle in the circumferential direction of the pile foundation hole site, and the hole protection piles are meshed together to form a pile casing; and drilling at the pile foundation hole site to form a pile foundation hole. The method solves the problems of high construction difficulty, high cost and long construction period when a conventional treatment method is adopted to construct the engineering pile in a foundation with poor dripping of a local soft soil layer and the like.
本发明公开了一种局部软弱土层地基中桩基成孔的施工方法，先确定地基中局部软弱土层的深度位置；于桩基孔位的外侧的局部软弱土层中打设多根护孔桩，护孔桩的上下两端分别伸至局部软弱土层的上方和下方的稳定土层中，多根护孔桩沿桩基孔位的周向方向设置一圈，多根护孔桩相互咬合在一起形成桩护筒；于桩基孔位钻进形成桩基孔。本发明解决了在存在局部软弱土层等不良滴出的地基中采用常规处理方法施工工程桩，存在施工难度大，成本高，工期常的问题。
