Rotary-jet diameter-expanding spiral soil-squeezing combined cast-in-place pile and pile forming method thereof
The invention provides a rotary-jet diameter-expanding spiral soil-squeezing combined cast-in-place pile and a pile forming method thereof, and relates to the technical field of building construction. The pile forming method of the rotary-jet diameter-expanding spiral soil-squeezing combined cast-in-place pile comprises the following steps that 1, geological detection of a construction site is conducted; 2, deviation theory correction of a drilling tool is conducted; 3, simulation of loading of a reinforcement cage is conducted; and 4, simulation of pouring is conducted. According to the rotary-jet diameter-expanding spiral soil-squeezing combined cast-in-place pile and the pile forming method thereof, the geology of the construction site is fully analyzed, and geological characteristics are combined with the computer technology to conduct live simulation; and through the solution in the steps, the problems of drilling deviation, reinforcement floating, pipe blocking, pile body breaking, hole collapse and the like can be effectively avoided, implementation is conducted after simulation reaches the relevant construction specifications, and the rework situation is prevented.
本发明提供旋喷扩径螺旋挤土组合灌注桩及其成桩方法，涉及建筑施工技术领域。该旋喷扩径螺旋挤土组合灌注桩及其成桩方法，包括以下步骤：第一步，施工地地质检测；第二步、钻具偏移理论校正；第三步，模拟装入钢筋笼；第四步，模拟灌注。本发明中通过对施工地的地质进行充分分析，并将地质特征结合计算机技术进行实况模拟，并且通过发明步骤中的解决方案，可以有效避免钻偏、钢筋上浮、堵管、桩体断裂以及孔坍塌等问题，在模拟达到相关施工规范后再进行实施，防止了返工情况的产生。
