Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of slope stability monitoring and risk early warning, particularly to a slope monitoring device integrated with multi-factor monitoring. BACKGROUND

[0002] Landslides are a common geological hazard, often triggered by rainfall, earthquakes, or human activities such as excavation and construction. These factors can cause ground loosening, which in turn can lead to landslides, posing a serious threat to human life and property. In particular, in urban development and river management, the stability of high slopes and deep foundation pits is a major concern. These areas often face the risk of landslides due to natural factors such as rainfall and water level changes, as well as human activities such as river erosion and ground excavation. In order to effectively manage these risks, it is crucial to implement slope stability monitoring.

[0003] Existing traditional slope stability monitoring solutions mostly rely on multiple different instruments and systems to measure parameters such as soil pressure, displacement, and pore water pressure, which leads to complex equipment installation, difficult maintenance, and low efficiency of data integration and analysis. In addition, these traditional systems often lack sufficient flexibility to cope with complex and variable geological environments, and their reliability and durability in harsh weather conditions are often questionable.

[0009] Further, the displacement and inclination sensor is arranged in the middle of the monitoring box body and monitors and records the displacement and inclination angle of the soil structure to monitor the stability of the slope soil structure, which is crucial for early identification of structural changes and potential safety problems, especially in monitoring slope stability.

[0010] Further, the signal processing unit includes an analog signal collector and a remote transmitter, the analog signal collector receives and converts analog signals of each sensor into digital signals, and the remote transmitter transmits digital signals outward, which is the core of the entire monitoring system, ensuring accurate conversion and rapid processing of signals.

[0021] The following will be described in combination with the drawings Figure 1 and the drawings Figure 2 The present application will be further described in detail.

[0022] As Figure 1 , Figure 2 and Figure 3 indicated, the composite slope monitoring device provided by the present application comprises a monitoring box body 1 and a remote monitoring terminal; the monitoring box body 1 can be taken out and placed in the soil of the slope, and a sensor is arranged inside; the sensor comprises a water content sensor 2 for monitoring the water pressure change in the soil, a soil pressure sensor for monitoring the pressure change of the soil, and a displacement and inclination sensor 6 for monitoring and recording the displacement and inclination angle of the slope structure.

[0023] In a specific implementation, the lower part of the monitoring box 1 is fixedly installed with a water content sensor 2, the probe of which extends from the lower hole of the box to contact the soil, for monitoring the water state in the soil, evaluating the soil saturation and the potential landslide risk of the slope; the upper part and the right side of the outer side of the monitoring box 1 are fixedly embedded with a vertical soil pressure sensor 3 and a horizontal soil pressure sensor 4, the soil pressure sensors on the outer side directly contact the soil to collect the changes of the soil pressure in the vertical and horizontal directions, and the displacement and inclination sensor 6 is arranged in the middle part of the monitoring box 1 and monitors and records the displacement and inclination angle of the soil structure to monitor the stability of the soil structure of the slope.

[0024] The water content sensor 2 is arranged in the lower part of the monitoring box 1, the monitoring probe of which extends downward into the soil at the bottom of the monitoring box 1 to monitor the change of the water pressure in the soil pores, analyze the soil saturation and predict landslides and other geological activities. The monitoring probe of the water content sensor 2 includes multiple probes which are arranged in a transverse direction and have the same extension length.

[0025] The soil pressure sensor includes a vertical soil pressure sensor 3 and a horizontal soil pressure sensor 4, the vertical soil pressure sensor 3 is arranged vertically on the monitoring box and monitors the change of the pressure of the soil on the monitoring box 1 in the vertical direction, and the horizontal soil pressure sensor 4 is arranged horizontally on the monitoring box and monitors the change of the pressure of the soil on the monitoring box in the horizontal direction.

[0026] As shown in Figure 2 The displacement and inclination sensor 6 includes a fixed support 10, a permanent magnet 11, a sliding block 13, a rotating platform 12 and a Hall sensor 8, the permanent magnet 11 is supported by the fixed support 10, the sliding block 13 slides on the horizontal sliding rail 9, the rotating platform 12 is arranged on the sliding block 13, and the Hall sensor 8 is arranged outside the transverse guide rail and monitors the change of the magnetic field in the near-field region. When the relative position between the sliding block 13 and the permanent magnet 11 changes due to the movement of the sliding block 13 or the rotation of the rotating platform 12, the Hall sensor 8 will respond and convert it into an electrical signal to calculate the displacement and inclination angle. The middle interlayer of the monitoring box 1 is a Hall displacement sensing device, the Hall sensor 8 in the device is used to monitor the change of the magnetic field in the near-field region, when the relative position between the sliding block 12 and the permanent magnet 11 changes due to the movement of the sliding block 12 or the rotation of the rotating platform 13, the sensor 8 will respond and convert it into an electrical signal to calculate the displacement and inclination angle, and the fixed support 10 on the platform provides a stable base for the permanent magnet.

[0027] The monitoring box 1 is further provided with a signal processing unit, the signal processing unit 5 is connected with each sensor signal, converts the analog signals of each sensor into digital signals and transmits the digital signals outward, and the power supply unit 7 is electrically connected with each sensor and the signal processing unit.

[0028] In a specific implementation, the inner side wall of the monitoring box 1 is installed with a signal processing unit 5 through a fixing mechanism, which is responsible for collecting analog signals from various sensors and converting them into digital signals for efficient data processing and analysis. The signal processing unit 5 includes an analog signal collector and a remote transmitter. The analog signal collector receives and converts the analog signals from various sensors into digital signals, and the remote transmitter transmits the digital signals outward.

[0029] The monitoring box 1 also has a power supply unit 7 inside, which includes a battery pack arranged in the monitoring box 1.

[0032] During installation, the monitoring device needs to be buried in the potentially dangerous sliding area, and the monitoring box is installed in the soil at the key monitoring position. The installation process mainly includes drilling at the predetermined position and installing the monitoring box to an appropriate depth to ensure that the sensors can effectively monitor the key data.

[0033] After the device is installed, the built-in signal processing unit 5 starts to work, responsible for collecting data from various sensors (such as the water content sensor 2, the vertical soil pressure sensor 3, the horizontal soil pressure sensor 4, and the displacement and inclination sensor), and these data are first converted into digital signals for further analysis and processing. The key to this process is to ensure that the collected data accurately reflects the real-time state of the slope, so as to respond quickly to potential risks. Once any abnormal situation is detected, such as the water content of the soil exceeding the normal range, sudden changes in soil pressure, or displacement and inclination exceeding the preset safety threshold observed by the displacement and inclination sensor, the system will immediately trigger the prompt signal lamp 15. These prompt signal lamps 15 will send obvious warning signals to engineers and monitoring centers, prompting them to take appropriate preventive or emergency measures to prevent or mitigate potential damage from landslides and other geological disasters.

[0034] The device is designed with easy maintenance and operability, so that when the demand changes or the equipment needs maintenance, the relevant personnel can quickly and safely adjust or replace the parts. The flexible configuration of the whole system and the powerful data processing capability make it an important tool to ensure the safety of the slope, effectively improving the accuracy and real-time of geological disaster warning.
