Tubular pile grouted core uplift test device and test method thereof
The invention belongs to the technical field of engineering pile foundations, and relates to a tubular pile grouted core uplift testing device. The device comprises a loading mechanism, a connecting mechanism and a displacement measuring mechanism, the loading mechanism comprises at least two jacks, one end of each jack is fixed above a tubular pile, and the other end of each jack is connected with a steel bar in a grouted core on the inner side of the tubular pile; the connecting mechanism comprises an upper base plate and a lower base plate which are arranged on the upper side and the lowerside of the jack, the upper base plate is connected with the reinforcing steel bar through a force transmission beam, and the lower base plate is arranged between the jack and the tubular pile; and the displacement measuring mechanism comprises a displacement meter and a displacement meter base used for fixing the displacement meter, the displacement meter base is fixed to the lower base plate, and a measuring end pointer of the displacement meter is perpendicular to the upper surface of the grouted core. The device can accurately test the uplift strength of the grouted core, the test data isstable and reliable, the problem that only the strength of the tubular pile is tested in the prior art is solved, and the device has the advantages of simple structure, convenience in operation, hightest precision, low test cost and the like.
本发明属于工程桩基础技术领域，涉及一种管桩灌芯抗拔测试装置，包括加载机构、连接机构和位移测量机构，所述加载机构包括至少两个千斤顶，所述千斤顶一端固定在管桩上方，另一端与管桩内侧灌芯中的钢筋连接；所述连接机构包括设置在千斤顶上下两侧的上垫板和下垫板，所述上垫板与钢筋之间通过传力梁连接，下垫板设置在千斤顶与管桩之间；所述位移测量机构包括位移计及用于固定位移计的位移计表座，所述位移计表座固定在下垫板上，所述位移计的测量端指针垂直于灌芯的上表面。本发明可以准确测试灌芯的抗拔强度，测试数据稳定可靠，解决了现有技术中仅有针对管桩强度测试的问题，具有结构简单，操作方便，测试精度高，测试成本低等优点。
