Steel pipe stirring composite pile and construction method thereof
The invention discloses a steel pipe stirring composite pile and a construction method thereof, and belongs to the technical field of foundation treatment. The construction method specifically comprises the following steps: S1 positioning a pile machine, wherein the pile machine is moved to a designated position, and the perpendicularity of the pile machine is adjusted; S2, stirring, spraying and drilling, namely starting a pile machine, rotating the steel pipe stirring core downwards to drill into the foundation, and spraying cement paste by the steel pipe stirring core at the same time; and S3, forming a pile, wherein specifically, after the steel pipe stirring core rotates to the pile bottom, the steel pipe stirring core is detached from a pile machine. The structural characteristics of the steel pipe stirring core are utilized, cement paste is sprayed and stirred while the steel pipe stirring core sinks to cut soil, three-step pile forming can be achieved, the pile pressing step during traditional composite pile construction is omitted, the construction efficiency is high, and the defect that the traditional pile type construction process is tedious is overcome. The composite pile has the advantages of being good in stress structure, high in bearing capacity, stable in quality, high in construction efficiency and simple in construction process.
本发明公开了一种钢管搅拌复合桩及其施工方法，属于地基处理技术领域。施工方法具体包括：步骤一、桩机定位：移动桩机到达指定位置，调整桩机的垂直度；步骤二、搅拌喷料下钻：启动桩机，将钢管搅拌芯向下旋转钻进地基，同时钢管搅拌芯喷射水泥浆；步骤三、成桩：钢管搅拌芯旋转至桩底后，将钢管搅拌芯从桩机上拆除。本发明利用了钢管搅拌芯的结构特征，在钢管搅拌芯下沉切土的同时进行水泥浆的喷射和搅拌，能够三步成桩，节省了传统复合桩施工时的压桩步骤，施工效率较快，弥补了传统桩型施工流程繁琐的缺点。且本发明的复合桩具有受力结构好、承载力高、质量稳定、施工效率高和施工流程简单的特点。
