Post-construction anchor cable prestress monitoring and mounting system and method
The invention relates to the technical field of anchor cable fastening, in particular to a post-construction anchor cable prestress monitoring and mounting system and method, and the system comprisesan existing anchor cable, an original anchorage device, a lengthened anchor cable, a connecting mechanism and a force application device; the connecting mechanism and the force application device aresequentially installed along the original anchorage device, the existing anchor cable is connected with the connecting mechanism through the original anchorage device, and the lengthened anchor cableis connected with the force application device through the connecting mechanism. Through anchor cable butt joint, a pressure sensor is arranged at the bottom of the original anchorage device; the anchor stress at the bottom of the anchor cable can be measured; a signal conversion and data transmission and analysis system is used, and the long-term monitoring on the anchor stress of the anchor cable is realized. According to the invention, the blank that the post-construction anchor cable cannot be monitored for a long time is filled up, the data is continuous, the regularity of the stress change under the anchorage of the anchorage device can be reflected, the automation of the anchor cable prestress monitoring is realized, and the anchor cable prestress early warning value can be set.
本发明涉及锚索紧固技术领域，更具体地，涉及一种工后锚索预应力监测安装系统及方法，包括既有锚索、原锚具、接长锚索、连接机构、施力装置；沿原锚具依次安装有连接机构、施力装置，既有锚索通过原锚具与连接机构连接，接长锚索通过连接机构与施力装置连接。通过锚索对接，在原锚具底部安装压力传感器，可以测量锚索底部锚下应力，并通过信号转换和数据传输与分析系统，实现对锚索的锚下应力进行长期监测，可以节省人工锚下应力试验的成本，本发明弥补了工后锚索无法长期监测的空白，数据具有连续性，能够反映出锚具锚下应力变化的规律性，实现了锚索预应力监测的自动化，能够设置锚索预应力预警值。
