The invention provides a construction method of a three-axis mixing pile. The construction method comprises the following steps that according to a coordinate datum point, lofting positioning and elevation guiding measurement work of the three-axis mixing pile are conducted according to a design drawing, and a mark is made; according to the mark made in the measurement positioning step and in combination with the design drawing, after the pile position center axis is determined and marked, upper filling and obstacles are excavated out of an excavation groove, and thus measurement and placement of a three-axis mixing pile hole position are conducted; in the pile machine in-place step, a mixer is moved to the three-axis mixing pile hole position measured and placed in the guide groove excavation step, the center of a drill bit of the mixer is aligned with the center of the three-axis mixing pile hole position, and a pulled rope is marked; and construction of the three-axis mixing pile is conducted through the in-place mixer by adopting a one-hole sleeving method, and the plane arrangement form of the three-axis mixing pile is one-jump-three or two-jump-four. According to the construction method of the three-axis mixing pile, the problem that the water stop effect is poor due to uneven guniting within different design elevation ranges is solved, and the construction efficiency and the construction operation quality are improved.
本发明提供了一种三轴搅拌桩施工方法，该施工方法包括如下步骤：根据坐标基准点，依据设计图进行三轴搅拌桩的放样定位和高程引测工作，并做好标志；根据测量定位步骤进行的标识并结合设计图，确定且标记桩位中心轴线后，将上部填土和障碍物挖除开挖沟槽，以进行三轴搅拌桩孔位的测放；桩机就位步骤，将搅拌机移至开挖导沟步骤测放的三轴搅拌桩孔位上，使搅拌机的钻头中心对准三轴搅拌桩孔位的中心，在已经拉好的线绳上做好标注；通过就位的搅拌机采用套接一孔法进行三轴搅拌桩的施工，三轴搅拌桩的平面布置形式为“做一跳三”或“做二跳四”。本发明解决了不同设计标高范围内喷浆不均匀导致止水效果不佳的问题，提高了施工效率和施工作业质量。
