Foundation pile static load test method adopting anchor cable to apply prestress
The invention discloses a foundation pile static load test structure adopting an anchor cable to apply prestress, which comprises a test foundation pile, a high-pressure jet grouting anchoring section, an anchor cable assembly and a test device used for providing upward tension for the anchor cable assembly and detecting the strain of a pile body of the test foundation pile, the high-pressure jet grouting anchoring section is positioned below the test foundation pile, and the high-pressure jet grouting anchoring section is positioned below the test foundation pile. The lower end of the anchor cable assembly is fixedly arranged in the high-pressure jet grouting anchoring section, a center pipeline is arranged in the center of the test foundation pile, and the upper end of the anchor cable assembly extends upwards to the position above the test foundation pile through the center pipeline and is connected with the testing device. When a static load test is carried out on the test foundation pile, the occupied space is small, construction of surrounding buildings and structures is not affected, the requirement for the surrounding environment is low, interference is small, the on-site in-situ test cost is reduced compared with a pile loading method and an anchor pile method, and time and labor are saved. Meanwhile, the method has the advantages of convenient construction, high flexibility, strong adaptability and the like.
本发明公开了一种采用锚索施加预应力的基桩静载试验结构，包括试验基桩、高压旋喷锚固段、锚索组件以及用于向所述锚索组件提供向上的拉力并检测所述试验基桩桩身应变的测试装置，所述高压旋喷锚固段位于所述试验基桩下方，所述锚索组件的下端固设于所述高压旋喷锚固段中，所述试验基桩中心设有一中心管道，所述锚索组件的上端通过所述中心管道向上伸出至所述试验基桩上方，并与所述测试装置相连。本发明在对试验基桩进行静载试验时，所占空间小不影响周围建构筑物施工，对周围环境要求低，干扰小，相较于堆载法和锚桩法降低了现场原位试验成本，且省时省力。同时，具有施工便捷，灵活性较高，适应性强等优点。
