Method for detecting vertical pulling-resistant static load of low-reinforcement-ratio pile foundation
The invention discloses a method for detecting the vertical pulling-resistant static load of a low-reinforcement-ratio pile foundation, the method applies a low-reinforcement-ratio pile foundation vertical pulling-resistant static load test device, and the low-reinforcement-ratio pile foundation vertical pulling-resistant static load test device comprises a buttress, a counter-force beam, a jack, an anchor plate, a conversion steel bar, a conversion anchor plate and a force measuring unit; the method comprises the steps that firstly, preparatory work is carried out, buttresses, counter-force beams, jacks and force measuring units are installed, then conversion anchor plates are installed on main reinforcements exposed out of a pile foundation, then the lower ends of conversion steel bars are installed on the conversion anchor plates, then anchor plates are installed at the upper ends of the conversion steel bars, and the conversion steel bars are connected with the anchor plates. Finally, a low-reinforcement-ratio pile foundation vertical anti-pulling static load test is carried out, when the vertical anti-pulling static load test is carried out, the jack pushes the anchor plate upwards, the conversion steel bars fixedly connected to the anchor plate pull the conversion anchor plate to move upwards, the conversion anchor plate can act on all main reinforcements of the pile foundation, and therefore the conversion anchor plate can act on all the main reinforcements of the pile foundation. The problem that all the main reinforcements are uniformly loaded is solved.
本发明公开了一种检测低配筋率桩基竖向抗拔静载的方法，所述方法应用低配筋率桩基竖向抗拔静载试验装置，所述低配筋率桩基竖向抗拔静载试验装置，包括：支墩、反力梁、千斤顶、锚固板、转换钢筋、转换锚固板和测力单元；所述方法为首先进行准备工作，安装支墩、反力梁、千斤顶和测力单元，再将转换锚固板安装在外露于桩基的主筋上，之后将转换钢筋的下端安装在转换锚固板上，然后将锚固板安装在所述转换钢筋的上端，最后进行低配筋率桩基竖向抗拔静载试验，进行竖向抗拔静载试验时，千斤顶向上推动锚固板，所述锚固板上固定连接的转换钢筋拉动转换锚固板向上运动，转换锚固板可以作用给桩基的每根主筋均匀向上的拉力，解决主筋全部均匀受荷问题。
