Single-pile vertical anti-pulling static load test device
The invention discloses a single-pile vertical anti-pulling static load test device which comprises a lower connecting device, an upper connecting device, a plurality of force transmission screws, a steel plate beam and a jack, the steel plate beam is arranged between the lower connecting device and the upper connecting device, the jack is arranged between the steel plate beam and the upper connecting device, and the two ends of the steel plate beam are each provided with a buttress concrete block. Two ends of the force transmission screw rod are respectively connected with the lower connecting device and the upper connecting device; the counter-force platform is directly anchored and connected with the detected pile reinforcing steel bar, the detected pile reinforcing steel bar does not need to be connected with the counter-force platform in a welding mode, the detected pile reinforcing steel bar can be disassembled after a test is finished and unloading is carried out, the welded reinforcing steel bar does not need to be cut and the like, the device is uniform in stress, and damage to a reinforcing steel bar cage caused by a traditional loading mode is improved; in addition, the lower connecting device is provided with a plurality of circular ring bodies, can be suitable for detection of a plurality of different pile diameters, is convenient to detect, and saves manpower and material resources.
本发明公开了一种单桩竖向抗拔静载试验装置，包括下连接装置、上连接装置、若干传力螺杆、钢板梁及千斤顶，钢板梁设置于下连接装置和上连接装置之间，千斤顶设置于钢板梁和上连接装置之间，钢板梁两端分别设置有一支墩砼块，传力螺杆两端分别与下连接装置和上连接装置连接；本发明的反力平台与受检桩钢筋直接锚固连接，受检桩钢筋不需要采用焊接的方式将钢筋与反力平台进行连接，待试验结束卸荷后即可拆卸，不需对焊接钢筋进行切割等，该装置受力均匀，改善传统加载方式对钢筋笼的破坏与受损；另，本发明的下连接装置设置有多个圆环体，可以适用于多个不同桩径的检测，检测方便，节省人力和物力。
