Soft soil bearing capacity testing device
The invention discloses a soft soil bearing capacity testing device which comprises a main body, the main body comprises a hydraulically-driven lifting seat, a driving mechanism is arranged on the lifting seat, a coring barrel is arranged in a coring drill rod, a first positioning groove is formed in the coring drill rod, a piston barrel with an opening in the bottom is arranged at the top of the coring barrel, and a piston is slidably arranged in the piston barrel. The piston is connected with a piston rod, the piston rod penetrates out of the top of the piston barrel to be connected with a first positioning mechanism, the piston barrel is provided with an overflow valve, the side face of the piston barrel is provided with an extension pipe, the extension pipe is movably sleeved with a detection pipe in a sealed mode, and the end of the detection pipe is sealed through an elastic layer. The detection end of the displacement sensor is connected with the elastic layer, an air/liquid inlet pipe communicated with the piston barrel is arranged above the detection pipe, a one-way valve is arranged on the air/liquid inlet pipe, and a first through hole is formed in the side face of the coring drill rod. And a strain relation curve of the transverse expansion length and the pressure or the stress can be drilled during coring.
本发明公开了一种软土地承载力测试装置，包括主体，主体包括液压驱动的升降座，升降座上设置有驱动机构，取芯钻杆内设置有取芯桶，取芯钻杆内设置有第一定位槽，取芯桶顶部设置有底部开口的活塞桶，活塞桶内滑动设置有活塞，活塞连接有活塞杆，活塞杆从活塞桶顶部穿出连接第一定位机构，活塞桶上设置有溢流阀，活塞桶侧面设置有延伸管，延伸管上密封活动套设有检测管，检测管端部通过弹性层密封，检测管内通过支架固定有位移传感器以及压力传感器，位移传感器的检测端连接弹性层，检测管上方设有与活塞桶连通的进气/液管，进气/液管上设有单向阀，取芯钻杆侧面设有第一通孔。能够在取芯的同时钻孔横向扩张长度与压力或应力的应变关系曲线。
