Vertical cyclic load loading test device for oil tank pile foundation settlement test
The invention belongs to the field of geotechnical engineering and oil and gas storage and transportation, and particularly relates to a vertical cyclic load loading test device for an oil tank pile foundation settlement test. The vertical cyclic load loading test device mainly comprises a box body bracket, a spring, a force sensor, a bearing box, a pile foundation model, a displacement sensor, amotor, a motor transmission rod, a free guide rail, a guide rail pulley, a first driving rod, a driven action rod, a central transmission gear and a fixed guide rail plate; and the vertical cyclic load loading test device is characterized in that a motor driving device of the device enables a lifting rod to ascend and descend in a reciprocating mode in the vertical direction through a gear transmission device, so that the spring is subjected to telescopic deformation, a load is generated through deformation of the spring and is applied to a pile foundation model, and the pile foundation modelis settled. The vertical cyclic load loading test device is easy to manufacture and convenient to operate, and a settlement rule of a pile foundation under the cyclic load can be tested.
本发明属于岩土工程和油气储运领域，具体地，涉及一种油罐桩基沉降测试的竖向循环荷载加载试验装置。主要包括箱体支架、弹簧、力传感器、承载箱、桩基模型、位移传感器、电机、电机传动杆、自由导轨、导轨滑轮、第一主动杆、从动作用杆、中央传动齿轮、固定导轨板，其特征在于：本发明装置的电机驱动装置通过齿轮传动装置使升降杆在竖直方向做往复升降，使弹簧发生伸缩形变，通过弹簧的形变产生荷载并将荷载施加到桩基模型上，使其发生沉降。本发明制作简易，操作方便，能够实现桩基在循环荷载下的沉降规律测试。
