Anchor pile and counter-force secondary beam connecting structure, device and method for static load test
The invention discloses an anchor pile and counter-force secondary beam connecting structure, device and method for a static load test. The anchor pile and counter-force secondary beam connecting structure comprises an anchor pile and a counter-force secondary beam, wherein the anchor pile comprises an upper pipe joint and a lower pipe joint, a groove is formed in the section cutting face of the lower pipe joint, the two ends of the groove communicate with the two opposite side walls of the lower pipe joint, the counter-force secondary beam is embedded in the groove, and the upper pipe joint is welded on the section cutting surface of the lower pipe joint and seals a top opening of the groove. According to the connecting structure, the tensile strength is provided for a butt weld between the upper pipe joint and the lower pipe joint, the stability of the counter-force secondary beam is improved through the constraint effect of the groove on the counter-force secondary beam, the contactstress area of the counter-force secondary beam and the anchor pile is increased through circumferential surface contact, the force transmission efficiency is improved, the stress concentration phenomenon is avoided, and particularly, the test device adopting the connection structure can improve the upper limit of force measurement and obtain more data.
本发明公开了一种静载试验的锚桩与反力次梁联结结构、装置及方法，包括锚桩和反力次梁；所述锚桩包括上管节和下管节，所述下管节的剖切面开设有凹槽；所述凹槽的两端连通下管节的相对两侧壁；所述反力次梁嵌合于凹槽中；所述上管节焊接于下管节的剖切面并将凹槽的顶部开口封闭。该联结结构以上管节与下管节之间的对接焊缝提供抗拉强度，凹槽对反力次梁的约束效果提升反力次梁的稳定性，反力次梁与锚桩呈周向面接触增大了二者接触受力的面积提升了传力效率，避免了应力集中现象。特别是采用该联结结构的试验装置能够提升测力上限，获取更多的数据。
