Punching cast-in-place pile construction method based on sandy gravel geological conditions
The invention discloses a punching cast-in-place pile construction method based on sandy gravel geological conditions, which comprises the following steps of: a, burying a pile casing at a preset position, aligning a pile machine with a pile position, and then mounting and fixing; b, the pile machine in the step a is used for carrying out impact hole forming operation at a preset position until a pile hole is formed, and the formed pile hole is cleaned for the first time; c, steel reinforcement cage limiters are installed in the pile holes in the step b, and then the steel reinforcement cage is hoisted into the pile holes provided with the steel reinforcement cage limiters; d, concrete is poured into the pile hole with the reinforcement cage in the step c; e, after the concrete is poured to the preset elevation, the steel reinforcement cage limiting stopper is dismantled; through the implementation of the method, the hole forming perpendicularity and the hole wall flatness are effectively controlled, the hole forming quality is improved, the problems of control over the pile foundation protection layer thickness and the sediment thickness and the like are solved, the construction quality is guaranteed, and the construction efficiency is improved.
本发明公开了一种基于砂卵石地质条件的冲孔灌注桩施工方法，该方法包括以下步骤：a.在预设的位置埋设护筒，将桩机对准桩位后安装并固定；b.使用步骤a中的桩机在预设位置开展冲击成孔作业至桩孔成孔，并对成孔的桩孔进行一次清孔；c.在步骤b中的桩孔内安装钢筋笼限位器，再将钢筋笼吊装至安装有钢筋笼限位器的桩孔内；d.向步骤c中装有钢筋笼的桩孔内灌注混凝土；e.混凝土灌注至预设标高后拆除钢筋笼限位器；通过该方法的实施，有效控制了成孔垂直度和孔壁平整度，提高了成孔质量，桩基保护层厚度和沉渣厚度控制等问题也得到了解决，保证了施工质量，提高了施工效率。
