The invention discloses a rotary compaction type variable-diameter pile construction technology, equipment needed by the construction technology comprises a screw pile machine, a screw pile machine power head, a variable-diameter drill rod, data acquisition equipment, a winch and the like, and the construction technology comprises the steps that firstly, after the screw pile machine is in place, the screw pile machine power head is used for promoting the lower portion of the variable-diameter drill rod to drill into soil, and the variable-diameter drill rod is driven to rotate; the drilling speed is synchronous with the drilling speed, and data acquisition is carried out through data acquisition equipment in the drilling process; and step 2, continuously promoting the upper part of the variable-diameter drill rod to drill into the soil until the upper part reaches the elevation position, and performing data acquisition through data acquisition equipment in the drilling process. The rotary compaction type variable-diameter pile (a cylinder or a screw or a full thread type) is designed, the variable-diameter pile technology is more advanced, the bearing capacity of the variable-diameter pile is further improved by compacting the soil around the pile body and carving, unearthed soil such as mucky soil is avoided, and environmental pollution is reduced.
本发明公开了一种旋转挤密式变径桩施工工艺，施工工艺所需设备螺杆桩机、螺杆桩机动力头、变径钻杆、数据采集设备及卷扬机等，所述施工工艺为：步骤一、螺杆桩机就位后，利用螺杆桩机动力头促使变径钻杆的下部钻入土壤中，下钻速度与钻进速度同步，钻入的过程中通过数据采集设备进行数据采集；步骤二、继续促使变径钻杆的上部钻入土中，直至达到标高位置，钻入的过程中通过数据采集设备进行数据采集。本发明设计旋转挤密式变径桩(圆柱或螺钉或全螺纹型)，使得变径桩技术更先进，通过挤密桩身周边土壤，且可以通过刻纹，进一步提升变径桩的承载力，且不出土，如存在淤泥质土，减少环境污染。
