Pile foundation visual model test limiting device and using method
The invention discloses a pile foundation visual model test limiting device. A model clamp is arranged on a sliding groove, a pile foundation model is arranged in the model clamp; a wheel shaft is arranged in clamping grooves in the bottom of the sliding groove; wheels are arranged at two ends of the wheel shaft; the middle of the wheel shaft is connected with an internal threaded pipe; the internal threaded pipe is connected with a threaded column; a micro pressure sensor and a signal wire are arranged on a partition at the lower end of the internal threaded pipe; the micro pressure sensor isconnected with a spring; the spring is connected with an abutting plate; and an antiskid rubber pad is arranged at the bottom of the abutting plate. The using method comprises the steps of assemblinga limiting device; adjusting the position of the model clamp, and clamping the pile foundation model; putting the pile foundation model into a soil body of a test model box; rotating the internal threaded pipe until the abutting plate and the antiskid rubber pad are abutted against the inner wall of the test model box; finely adjusting and rotating the internal threaded pipe, observing the horizontal supporting force, and stopping rotating when a designed load value is reached; stuffing the test model box with model soil; and applying a load to the pile foundation to finish data acquisition so as to prevent oil particles from entering a fine gap between the foundation and the wall of the transparent model box.
一种桩基础可视化模型试验限位装置，滑槽的上设有模型夹；模型夹内设置桩基础模型；滑槽底部的卡槽内设有轮轴；轮轴两端设有轮；轮轴中部与内螺纹管相连；内螺纹管与螺纹柱连接；内螺纹管下端的隔板上设有微型压力传感器和信号线；微型压力传感器与弹簧相连；弹簧与抵板相连；抵板底部设有防滑胶垫；使用方法的步骤是：组装限位装置；调节模型夹位置，夹紧桩基础模型；将桩基础模型放至试验模型箱土体中；旋转内螺纹管，直到抵板与防滑胶垫抵于试验模型箱内壁；微调旋转内螺纹管，观测水平支撑力大小，到设计荷载值时停止旋转；试验模型箱内填筑模型土；对桩基础施加荷载，完成数据采集；可有效阻止土颗粒进入基础与透明模型箱壁的细微间隙中。
