Construction process of cast-in-situ bored pile
The invention discloses a construction process of a cast-in-situ bored pile. The construction process comprises the steps of lofting the position of the pile, positioning a pile machine, forming a pile foundation hole, manufacturing and mounting a reinforcement cage, placing a guide pipe, pouring concrete and detecting an engineering pile. The construction process has the beneficial effects that apile position control pile adopts a wood pile and a small nail, the buried depth is not less than 20 cm, and the pile position is preferably protected; additionally, stake numbers are marked, so thatconfusion is prevented; control points of a construction site are checked frequently, so that errors are avoided; a steel plate with the thickness of 20 mm is cushioned under the pile machine, so that uneven subsidence is avoided, and excessive vertical deflection of the formed hole, unqualified perpendicularity and even toppling accidents of a drilling machine are avoided; and according to the construction process, mechanical equipment which adapts to engineering and has good performance is adopted and is scientifically arranged on a production line, so that the production capacity of the equipment is brought into full play, and the environment-friendly and civilized construction is facilitated.
本发明公开了一种钻孔灌注桩施工工艺，包括桩位放样、桩机就位、桩基成孔、钢筋笼制作及安装、安放导管、混凝土灌注、工程桩检测。本发明的有益效果是：桩位控制桩采用木桩加小钉，入土深度不少于20cm，并做好桩位的保护；同时应对桩号做好标识，以防止混淆；对施工现场的控制点应经常检查，避免发生误差；在桩机下垫20mm厚的钢板以免产生不均匀沉陷，避免造成成孔竖向偏斜过大，垂直度不合格，甚至导致钻机倾倒事故发生；本施工工艺采用和工程相适应、性能良好的机械设备，科学配置于生产线，充分发挥设备的生产能力，有利于环保和文明施工。
