Pedestal pile mechanical hole-forming model test device under servo control and use method
The invention discloses a pedestal pile mechanical hole-forming model test device under servo control and a use method. In the model test device, a model box is filled with test soil, and a model pedestal pile is buried in the test soil. A hydraulic jack provides power for downward drilling, and a servo moor controls the drilling rate. Uniform-section straight-segment hole forming of the model pedestal pile is performed through a power control appliance and a connecting rod, and expanding-pedestal-segment hole forming of the model pedestal pile is achieved through the power control appliance,the connecting rod and a hole expanding mechanism. The model test device is high in automatic control level, and can simulate the dry operation mechanical hole-forming construction process of the pedestal pile, precisely control mechanical hole-forming parameters of the pedestal pile and simulate mechanical hole-forming of the model pedestal pile in foundation soil with different characteristics.
本发明公开了一种伺服控制的扩底桩机械成孔模型试验装置及使用方法，本发明采用模型箱装填试验用土体，试验用土体中埋置扩底模型桩。通过油压千斤顶提供向下钻孔的动力，由伺服电机控制钻孔速率。通过动力控制设备和连接杆进行扩底模型桩等截面直段成孔；通过动力控制设备、连接杆及扩孔机构实现扩底模型桩扩底段成孔。本发明自动化控制水平高，能够模拟扩底桩干作业机械成孔施工过程，能进行扩底桩机械成孔参数精确控制，能在不同特性地基土中进行扩底模型桩机械成孔模拟。
