Device and method for preventing upper-section pile from being ejected out in pile bearing capacity self-balancing test
The invention discloses a device and method for preventing an upper-section pile from being ejected out in a pile bearing capacity self-balancing test. The device for preventing the upper-section pile from being ejected out in the pile bearing capacity self-balancing test. The device comprises a disc and an oil pump, wherein a pressure chamber, a telescopic hole, a piston and an inserting rod are arranged in the disc, and the oil pump communicates with the pressure chamber to supply oil to the pressure chamber; one end of the telescopic hole is formed in the side portion of the pressure chamber and communicated with the pressure chamber, the other end of the telescopic hole extends to an edge of the disc and is provided with an outlet, the piston is slidably installed in the telescopic hole and divides the telescopic hole into two cavities which are not communicated with each other, the piston is matched with the insertion rod, and the insertion rod is arranged in the cavity close to the outlet side; when the oil pump pressurizes, liquid in the pressure chamber pushes the piston to move, and the inserting rod arranged in the disc synchronously moves along the telescopic hole and is inserted into the soil layer. The device can prevent the upper-section pile from being ejected out in a pile bearing capacity self-balancing test.
本发明公开了一种桩承载力自平衡测试中防止上段桩顶出的装置及方法，一种桩承载力自平衡测试中防止上段桩顶出的装置，包括圆盘和油泵，所述圆盘内设有压力室、伸缩孔、活塞和插杆，油泵与压力室连通为压力室供油，伸缩孔一端设置在压力室侧部且与压力室连通，伸缩孔另一端延伸至圆盘边缘且设置出口，活塞可滑动安装在伸缩孔内并将伸缩孔分隔成两个互不连通的腔室，活塞与插杆配合，插杆设置在靠近出口侧的腔室内；油泵加压时，压力室中的液体推动活塞移动，设置在圆盘内的插杆沿伸缩孔同步移动并插入土层。本发明可以在桩承载力自平衡测试中，防止上段桩被顶出。
