Pneumatic dynamic penetration test device and test method
The invention discloses a pneumatic dynamic penetration test device and a test method. The device comprises a rack, a consolidation bin, a driving air cylinder and a dynamic sounding rod, the consolidation bin comprises a bin cover and a bin body, a guide pipe is inserted in the bin cover, the driving air cylinder is arranged on the rack in a vertically movable mode through a height adjusting mechanism, the consolidation bin is located below the driving air cylinder, and the dynamic sounding rod is installed at the driving end of the driving air cylinder. And the driving cylinder drives the dynamic sounding rod to extend into the bin body through the guide pipe. The height of the driving cylinder is adjusted according to requirements, the cylinder pressure and the cylinder stroke of the driving cylinder are adjusted according to the initial speed required by test simulation, a sample is placed in the consolidation bin and below the driving cylinder, the driving cylinder is started, and the dynamic sounding rod is vertically and downwards accelerated to pass through the guide pipe under the pushing action of the cylinder; and then injecting into a sample in a consolidation bin to obtain mechanical parameters. The device has the advantages of being non-destructive, high in measuring speed, high in measuring precision, simple to operate and low in cost.
本发明公开了气动式动力触探试验装置和试验方法。装置包括机架、固结仓、驱动气缸和动力触探杆，固结仓包括仓盖和仓身，仓盖上插设有导向管，驱动气缸通过高度调节机构可上下活动的设置在机架上，固结仓位于驱动气缸的下方，动力触探杆安装在驱动气缸的驱动端，驱动气缸驱动动力触探杆经由导向管伸入仓身中。本发明根据需求调节驱动气缸的高度，根据试验模拟需要的初速度调整驱动气缸的气缸气压与气缸行程，将固结仓内放置试样，并放置在驱动气缸的下方，启动驱动气缸，动力触探杆在气缸推动作用下竖直向下加速通过导向管，随后贯入固结仓的试样中获得力学参数。本发明的装置具有非破坏性、测量速度快、测量精度高、操作简单和成本较低的优势。
