Device and method for excavating pile foundation scouring pit in geotechnical centrifuge model box
The invention discloses a device and method for excavating a pile foundation scouring pit in a geotechnical centrifuge model box, and the device comprises a positioning arm mechanism which comprises a first drive control system and a mechanical arm; the first driving control system is used for driving the mechanical arm; the disc is rotationally connected to the working end of the mechanical arm; one end of the aluminum bar is mounted on the disc; the support is arranged on the upper middle section of the aluminum bar so that the aluminum bar can move in the axial direction of the support, and radial displacement is limited; the control mechanism comprises a winch motor and a telescopic control arm; the pulley is mounted at one end of the pull rod away from the telescopic control arm; the steel wire is wound on the pulley; the other end of the steel wire is connected with the bottom of the aluminum bar; the winch motor and the telescopic control arm are both electrically connected with a second drive control system. A centrifuge is installed at one end of the mechanical arm. The device has the function of excavating any irregular pit, and the effect of simulating the scouring pit generated by water flow scouring is improved.
本发明公开一种土工离心机模型箱内桩基冲刷坑开挖装置及方法，装置包括定位臂机构，包括第一驱动控制系统和机械臂；第一驱动控制系统用于驱动机械臂；圆盘，转动连接在机械臂的工作端；铝棒，一端安装在圆盘上；支架，设于铝棒的中上段，以使得铝棒能够沿其轴向位移，且径向位移受限；控制机构，包括卷扬电机和伸缩控制臂；滑轮，安装在拉杆远离伸缩控制臂的一端；钢丝，绕设在滑轮上；钢丝的一端与卷扬电机连接，另一端与铝棒的底部连接；其中，卷扬电机和伸缩控制臂均电性连接有第二驱动控制系统；机械臂的一端安装有离心机。本发明具有开挖任意不规则坑的功能，提高了模拟出水流冲刷产生的冲刷坑的效果。
