Abstract

The invention provides a multi-vector side slope monitoring anchor rod based on Big dipper location and a monitoring method. The side slope monitoring anchor rod is formed by four parts including an end portion signal receiving and outputting device, a multi-section sensor inner core, a hydraulic three-tip anchor head and an outer cover protecting cylinder. The end portion signal receiving and outputting device mainly receives locating signals of the Big dipper. The multi-section sensor inner core is a core part and can be arranged into the side slope like the anchor rod, the multi-section sensor inner core and surrounding soil bodies or rock bodies are anchored in a multi-point manner through anchoring rings, an axial stress sensor, a torque sensor and an axial strain sensor are arrangedinside, and by means of a cable, convergence to the end portion signal receiving and output device. The hydraulic three-tip anchor head jacks the anchoring rings in the multi-section sensor inner coreout to expand, and anchoring with the surrounding soil bodies or surrounding rock is achieved. After hole forming, the multi-section sensor inner core is arranged in the outer cover protecting cylinder so as to be protected. According to the anchor rod, Big dipper location and navigation are adopted for initially monitoring the trend of occurrence of landslip, the exquisite sensor determines theposition of risk of landslip, and necessary data support is provided for early warning of landslip and treatment of project slipping resistance.

Description

technical field [0001] The invention relates to a multi-vector slope monitoring bolt and a monitoring method based on Beidou positioning. Set monitoring anchors on the slope or shoulder of the slope that needs to be monitored. When the slope has a sliding tendency or cracks and deformation, the Beidou satellite positioning signal can be received through the end signal receiving and output device to determine the approximate deformation of the entire slope. direction, and then according to the sensor data of the multi-section sensor core, the specific location and depth of sliding deformation or crack generation can be obtained, and decision-making data can be provided for slope reinforcement and landslide early warning. The invention adopts an unattended working form, all data are transmitted through wireless, and relevant data can be analyzed indoors after receiving the relevant data regularly, which reduces the time for personnel to stay in dangerous areas in the wild. The ...
