Method for detecting uplift bearing capacity of prestressed pipe pile
The invention relates to a method for detecting the uplift bearing capacity of a prestressed pipe pile, which belongs to the technical field of uplift pipe piles, and comprises the following steps: arranging sleepers with the same height on the two sides of the prestressed pipe pile respectively, arranging a cross beam at the top ends of the sleepers, and arranging a motor and a detection device on the cross beam; the motor is started to reach preset thrust until the motor automatically stops, and the displacement condition of the prestressed pipe pile in the vertical direction is measured; the detection device comprises a measuring frame and a driving mechanism for providing power for the vertical movement of the measuring frame; the driving mechanism is arranged at the top of the crossbeam; the bottom of the measuring frame is fixedly connected with a plurality of connecting shafts, and the measuring frame is slidably connected with a trigger plate in the vertical direction through the connecting shafts. A second electromagnet is arranged on the trigger plate, and a magnetic attraction piece capable of being magnetically attracted to the second electromagnet is arranged at the top of the prestressed pipe pile; a switching mechanism for communicating the electromagnet II with a power supply is arranged on the cross beam. The tubular pile pull-out test device has the effect of automatically carrying out the tubular pile pull-out test.
本申请涉及一种预应力管桩抗拔承载力检测方法，属于抗拔管桩的技术领域，其包括如下步骤：在预应力管桩两侧分别设置等高的枕木，在枕木顶端设置横梁，于横梁上设置电机及检测装置；启动电机并使其达到预设的推力，直至电机自动停止，测量预应力管桩沿竖向的位移情况；检测装置包括测量架以及为测量架的竖向移动提供动力的驱动机构；驱动机构设置于横梁顶部；测量架底部固接有若干个连接轴，测量架通过连接轴沿竖向滑移连接有触发板；触发板上设置有电磁铁二，预应力管桩顶部设置有可与电磁铁二进行磁吸附的磁吸片；横梁上设置有连通电磁铁二与电源的开关机构。本申请具有自动化进行管桩抗拔试验的效果。
