Construction method for pit-in-pit reinforcement through three-shaft mixing pile
The invention relates to the technical field of building engineering construction, in particular to a construction method for pit-in-pit reinforcement through a three-shaft mixing pile. The method specifically comprises the following steps that a construction site is leveled; pile position lofting, ditching and grooving are carried out, and a mud pit is dug in a construction site; a pile machine is in place; correcting the perpendicularity of the pile frame; preparing cement grout; stirring to form a pile; and carrying out lap joint construction on the three-shaft stirring pile. According to the construction method, the reinforcing width and depth are wider, the formed effective reinforcing action area is larger, the construction cost is lower, the construction technology is simpler, the construction requirement is lower, and the reinforcing effect generated after construction is better. In the construction process, the three-shaft mixing pile is adopted, replacement filling or machining of on-site undisturbed soil is not needed, construction can be directly carried out in the undisturbed soil, and the engineering cost is saved to a great extent.
本发明涉及建筑工程施工技术领域，尤其是涉及一种三轴搅拌桩进行坑中坑加固的施工方法。具体包括以下步骤：平整施工场地；桩位放样，开沟挖槽，在施工现场挖设泥浆池；桩机就位；校正桩架垂直度；准备水泥浆液；搅拌成桩；三轴搅拌桩的搭接施工。本发明提供的施工方法加固的宽度、深度更广，形成的有效加固作用区域更大，施工成本更低、施工工艺更简洁、施工要求更低，施工后产生的加固效果更好。在施工过程中采用三轴搅拌桩，不需要对现场原状土进行换填或加工，可以直接在原状土中进行施工，很大程度的节约了工程成本。
