Description

Technical Field

[0001] The invention relates to the technical field of geotechnical engineering, and in particular to a road slope reinforcement anchor cable. Background Art

[0002] Due to the large undulations in mountainous terrain, there are many dangerous rocks on the slopes. In addition, most of my country is in the subtropical monsoon climate zone, with high temperatures and heavy rains in summer. Most of the western regions are in the Pacific Rim volcanic seismic belt, where geological activities are frequent. The number of projects such as road cutting slopes and foundation pit support in my country has increased significantly, and problems such as slope instability and collapse are becoming more and more serious. At present, there are too few or immature monitoring technologies for anchor reinforcement. The existing anchor reinforcement methods are difficult to grasp the status of slopes and anchors in real time, which poses certain safety hazards. In addition, the geological conditions of different slopes are complex and diverse, and the status of slopes may change dynamically with time, climate, external loads and other factors. The existing anchor reinforcement system is often difficult to adapt to these changes. Therefore, it is of great significance to quickly monitor slope deformation and anchor stress in real time, and better adapt to complex geological conditions and dynamically changing slope anchor reinforcement systems.

[0003] Therefore, it is urgent to develop an intelligent adaptive slope anchor reinforcement system, which can monitor the anchor stress, slope displacement and environmental parameters in real time through the sensor module, timely detect potential dangerous situations, and greatly improve the safety of slope reinforcement. The prestressing adjustment device can automatically adjust the prestressing of the anchor according to the data monitored by the sensor, so that it can better adapt to various complex geological conditions and dynamically changing slopes, ensure that the slope can remain stable under different conditions, and realize remote monitoring, reducing costs and manpower investment. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide an intelligent adaptive slope anchor reinforcement system, which can automatically adjust the prestress applied by the anchor according to the data monitored by the sensor, ensure that the anchor is always in the best working state, and improve the stability of the slope.

[0005] The intelligent adaptive slope anchor cable reinforcement system of the present invention comprises an anchor cable, a prestress adjustment device, a sensor module and a data processing module. The anchor cable is a prestressed anchor cable. The prestress adjustment device can adjust the prestress applied to the anchor cable. The sensor module is used to collect status data of the anchor cable and the slope and transmit the data to the data processing module.

[0006] Furthermore, the anchor cable includes an outer anchor head, a tension anchor rod, an anchor and an anchor cable body, the outer anchor head also includes an anchor sealing box, and the anchor also includes a tension section anchor and an anchor section anchor.

[0007] Furthermore, the tension anchor rod is connected to the tension section anchor and is fixed to the prestress adjusting device, so as to bear and transmit the prestress applied by the prestress adjusting device to the anchor cable.

[0008] Furthermore, the prestressing force adjusting device is located in the anchor sealing box of the outer anchor head, and can receive instructions from the data processing module to adjust the prestressing force applied to the anchor cable in a hydraulic or mechanical manner.

[0009] Furthermore, the sensor module comprises:

[0010] Stress sensor, used to monitor the stress change data of anchor cable;

[0011] Torque sensor, used to monitor the torque change data of the anchor cable;

[0012] Displacement sensor, used to monitor the displacement change data of the anchor cable;

[0013] Environmental sensors are used to collect environmental parameters around the slope.

[0014] Furthermore, the stress sensor is located in the tensioning section anchor, the torque sensor and the displacement sensor are located in the anchor sealing box, and the environmental sensor is integrated in the data processing module.

[0015] Furthermore, the data processing module receives the data transmitted by the sensor module, performs analysis and processing, determines the stability of the slope and the working state of the anchor cable according to a preset algorithm and threshold, and sends instructions to the prestressing adjustment device.

[0016] Furthermore, the data processing module is externally mounted on the anchor cable, and can upload the slope data and the anchor cable status from the background terminal.

[0017] Beneficial effects of the present invention: The intelligent adaptive slope anchor cable reinforcement system of the present invention monitors the displacement of the slope and the stress of the anchor cable in real time through sensors, can promptly detect the potential unstable state of the slope, and automatically adjust the prestress applied to the anchor cable, so that the anchor cable can be dynamically adjusted according to the actual situation of the slope, ensuring that the anchor cable is always in the best working state, thereby better exerting its reinforcement effect and effectively improving the stability of the slope.
