Large-tonnage pull-out test device
The invention relates to the technical field of detected pile detection, in particular to a large-tonnage pull-out test device which comprises force application units, a force transmission steel beam, a force bearing seat, a load measuring unit and a pull-up amount measuring unit, the force transmission steel beam is fixedly provided with the force bearing seat and the two force application units, the force bearing seat is located between the two force application units, and the pull-up amount measuring unit is located between the two force application units. The force application unit is used for transmitting upward pressure to the force transmission steel beam, a connecting rod is arranged at the lower end of the stress base, the load measuring unit is installed on the force application unit, and the upward pulling amount measuring unit is installed on the stress base. The device has the advantages that the connecting rod of the stress base can be directly welded to the top of the detected pile, and the force application unit applies tension to the detected pile through the force transmission steel beam; the stress base is located between the two force application units, and the tensile force borne by the stress base is actually the resultant force of the two force application units, so that the tensile force borne by the detected pile in the test process is improved, and the test requirement is met.
本发明涉及受检桩检测技术领域，特别是涉及一种大吨位抗拔试验装置，包括施力单元、传力钢梁、受力座、荷载测量单元和上拔量测量单元，所述传力钢梁固定有所述受力座和两个所述施力单元，所述受力座位于两个所述施力单元之间，所述施力单元用于向所述传力钢梁传递向上的压力，所述受力座的下端设有连接杆，所述荷载测量单元安装于所述施力单元，所述上拔量测量单元安装于所述受力座。其有益效果在于：受力座的连接杆可以直接与受检桩的顶部焊接，其由施力单元通过传力钢梁实现对受检桩施加拉力的作用；受力座位于两个所述施力单元之间，受力座所受拉力实际为两个施力单元的合力，从而提高受检桩在试验过程中所受的拉力，满足试验要求。
