Treatment method for hole collapse of dry pore-forming cast-in-place pile
The invention discloses a method for treating a collapsed hole of a dry hole-forming cast-in-place pile. The method comprises the steps of hole cleaning, concrete recharging through a conventional machine tool, concrete protection wall forming, reinforcement cage backfilling, pouring and the like. The problem that the pile casing cannot be pulled out during treatment in a traditional scheme is solved, the economical efficiency in the implementation process is good, and the construction difficulty is low; the collapsed hole can be timely and effectively treated, expansion of the collapsed hole can be rapidly inhibited, and the design strength of a pile foundation after the collapsed hole is treated can be well met.
本发明公开了一种干成孔灌注桩塌孔的处理方法，包括清孔、利用常规机具回灌混凝土、形成混凝土护壁、回填钢筋笼并浇筑等步骤。本发明克服了传统方案处理时无法拔出护筒的难题，实施过程经济性好，施工难度低；对塌孔的处理及时有效，能快速抑制塌孔的扩大，而且能很好地满足了塌孔处理后桩基的设计强度。
