Description

Technical Field

[0001] This invention relates to the field of slope protection monitoring technology, specifically a low-damage road slope settlement monitoring system and its monitoring method. Background Technology

[0002] Roadbed slopes refer to the sloping surfaces on both sides of the roadbed cross-section that connect to the ground. They are classified as embankment slopes and cutting slopes, and are an important factor affecting roadbed stability. The shape of slopes in roadbeds is often constructed as single-slope, zigzag, or stepped shapes. The slope of each slope segment is expressed as the ratio of the elevation difference between two points on the slope cross-section diagram to the horizontal distance.

[0003] Existing road slope monitoring devices have the following disadvantages:

[0004] 1. Setting up monitoring points on the slope surface and fixing the monitoring points to the slope surface will damage the slope structure, put pressure on the slope, and cause large-scale damage to the slope after setting up multiple monitoring points, causing the slope to settle and resulting in road slope damage.

[0005] Second, the monitoring effect is poor, and small-scale settlement of the slope is not easily detected;

[0006] Third, the monitoring accuracy is poor. When the slope soil moves vertically and horizontally, the monitoring device is not convenient to monitor simultaneously and it is not easy to determine the direction of settlement, which makes it inconvenient for remedial and maintenance treatment. Summary of the Invention

[0007] The purpose of this invention is to provide a low-damage road slope settlement monitoring system and method to solve the problems in the prior art.

[0008] The objective of this invention can be achieved through the following technical solutions:

[0009] A low-damage road slope settlement monitoring system includes a monitoring system for monitoring road slope displacement, a transmission system connected to the monitoring system for data transmission, a power supply system connected to the monitoring system and the transmission system for power supply, and a layout system for drilling and arranging magnetic particle monitoring holes.

[0010] Furthermore, the monitoring system also includes a housing;

[0011] The enclosure includes a mounting plate for mounting the monitoring system, which secures the monitoring system above the monitoring hole via a monitoring column.

[0012] The monitoring system includes a sensor installed inside the housing, a processor installed on one side of the sensor, and magnetic powder installed below the monitoring column.

[0013] Furthermore, the transmission system includes a transmission module and a data terminal, which are connected to transmit monitoring signals.

[0014] The connection methods include wireless connection and wired connection.

[0015] Furthermore, the data terminal is used to receive data sent by the transmission module and determine the uneven settlement, total settlement, voids, changes in the slope soil displacement field, and changes in the foundation soil displacement field of the slope.

[0016] Furthermore, the sensor includes a magnetometer, which is used to monitor the displacement of magnetic particles in the soil of the slope and determine whether the road slope has settled.

[0017] Furthermore, the deployment system includes a drill bit, one end of which is provided with a first drill bit for drilling monitoring holes on the roadside slope, and a movable second drill bit on one side of the drill bit for drilling sidewall holes in the inner wall of the monitoring hole. The drill bit and the second drill bit are connected by a hydraulic rod.

[0018] Furthermore, the power supply system includes a support column and a solar panel. The support column is equipped with a power supply component, which includes a solar panel, a battery controller, a battery, and a DC-AC converter. The solar panel is connected to the battery controller to transmit the absorbed and converted electrical energy to the battery controller. The battery controller receives the electrical energy and connects it to the battery for storage. The battery is connected to the DC-AC converter to convert DC power into AC power.

[0019] A method for monitoring low-damage road slope settlement, the method comprising the following steps:

[0020] 1) Technical preparation: Review the drawings and select a reasonable process, collect relevant information on the slope, and formulate corresponding protection measures for existing buildings that may be affected.

[0021] 2) Material preparation: According to the material usage plan, reasonably arrange and determine the monitoring positions. Along the road direction, set up a monitoring post every 10-15 meters. For locations with loose soil and prone to settlement, the spacing can be shortened to a monitoring post every 5-10 meters.

[0022] 3) Drill hole layout:

[0023] Construction is carried out at the pre-set installation points. The first drill bit is used to drill vertically into the slope to form a monitoring hole. During the drilling process of the first drill bit, the second drill bit is moved to drill side wall holes into the inner wall of the hole every 4-5 cm. After the drilling is completed, multiple side wall holes are set vertically in the monitoring hole.

[0024] 4) Magnetic powder introduction:

[0025] The magnetic powder is evenly introduced into the side wall hole, and sufficient magnetic powder is added into the monitoring hole. Then, the soil generated during drilling is backfilled into the monitoring hole.

[0026] 5) Installation of the detection system:

[0027] Install each component of the monitoring system on the monitoring column, set the initial value of the magnetic powder, install the power supply system, connect the power supply system and the monitoring system, connect the monitoring system to the data terminal, set the displacement limit of the magnetic powder on the data terminal, and complete the installation of the entire system.

[0028] 6) Real-time monitoring:

[0029] If the slope experiences vertical or horizontal displacement, the magnetic particles will move along with the soil. The sensor monitors the displacement of the magnetic particles, sends the data to the processor for processing, and then transmits it to the data terminal via the transmission module. The monitor judges the condition of the slope based on the information from the data terminal. When the magnetic particles deviate beyond the set displacement limit, the data terminal issues an alarm signal to remind the monitoring personnel to take timely emergency measures and perform timely maintenance.

[0030] The beneficial effects of this invention are:

[0031] 1. The monitoring system of the present invention uses magnetic powder to be sprinkled in the slope structure. The movement of the slope causes the magnetic powder to shift. The sensor detects the movement of the magnetic powder and judges the changes in the slope displacement field, the changes in the foundation soil displacement field, uneven settlement, total settlement, voids and other phenomena based on the movement of the magnetic powder.

[0032] 2. The monitoring method of the present invention only involves drilling holes to lay magnetic powder on the slope and backfilling the holes with soil, which causes little damage to the slope and has low construction cost. The monitoring system can monitor the slope in real time by monitoring the magnetic powder. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] A low-damage road slope settlement monitoring system, such as Figure 1 , Figure 2 As shown, the monitoring system includes a transmission system, a monitoring system, a power supply system, and a deployment system.

[0040] The detection system also includes a housing 6, which is a sealed housing 40-50cm long, 50-80cm long, and 10-20cm high, composed of 2-6cm thick transparent plexiglass panels, which are fixedly connected by gluing. The transmission system includes a transmission module 5 and a data terminal. The transmission module 5 is connected to the data terminal to transmit monitoring signals. The connection methods include wireless connection and wired connection to transmit signals in different ways.

[0041] The monitoring system includes a sensor 3, a processor 4, and magnetic powder. The magnetic powder is placed in the roadside slope through a deployment system and monitored by the sensor 3. The information of the detected magnetic powder is transmitted to the processor 4 connected to the sensor 3. The processor 4 is connected to the transmission module 5 in the transmission system and transmits the processed information to the transmission module 5, which then transmits it to the data terminal.

[0042] Among them, sensor 3 includes a magnetometer, and the specific method of magnetic particle monitoring is as follows: sensor 3 is used to monitor the magnetic field generated by magnetic particles in the slope soil. Before monitoring, the magnetic particles are placed at the monitoring point, and the strength and direction of the magnetic field generated at this time are set as initial values. When the magnetic particles move, sensor 3 monitors the changing magnetic field strength and direction of the magnetic particles. Based on the magnetic declination and magnetic inclination, the Earth's magnetic field is measured and each component is reflected, thereby calculating the direction and distance of the magnetic particles' movement, judging the vertical and horizontal displacement of the road slope, and judging whether the road slope has settled.

[0043] The deployment system includes a drill bit 1, with a first drill bit 11 at one end. The first drill bit 11 is vertically positioned for vertical drilling on roadside slopes. A second drill bit 2 is located on one side of the drill bit 1. A hydraulic rod is installed inside the drill bit 1, and the output end of the hydraulic rod is connected to the second drill bit 2, controlling the second drill bit 2 to move outward from the drill bit 1. This allows the second drill bit 2 to drill outward from the hole wall drilled by the first drill bit 11, forming sidewall holes. In the monitoring hole drilled by the first drill bit 11, the second drill bit 2 drills into the inner wall of the hole at intervals of 4-5 cm. Multiple sidewall holes are evenly set along the direction of the monitoring hole. Magnetic powder is introduced into the sidewall holes, and magnetic powder is injected into the monitoring holes. The soil is then buried back into the holes. When the soil moves, it will move the magnetic powder, and the movement of the magnetic powder can be used to determine whether the soil has shifted.

[0044] The housing 6 has an internal mounting plate on which a sensor 3, a processor 4, and a transmission module 5 are fixedly mounted. The mounting plate is fixed to the monitoring column 10, which is positioned above the monitoring hole to facilitate the detection system's monitoring of the magnetic particles.

[0045] The power supply system includes a support column 7 and a solar panel 8. The support column 7 is equipped with a power supply component, which includes a solar panel 8, a battery controller, a battery, and a DC-AC converter. The solar panel 8 absorbs solar energy and supplies it to the battery controller. The battery controller outputs DC power. After connecting the battery controller to the battery, the electrical energy converted during the day is stored in the battery. Then, it is converted to AC power by the DC-AC converter. The power supply component is connected to the deployment system and the monitoring system through wires 9 to provide power to the deployment system and the monitoring system.

[0046] The data terminal is used to receive data sent by the transmission module. Based on the movement of magnetic particles in the slope soil, it can determine the uneven settlement, total settlement, voids, changes in the slope soil displacement field, and changes in the foundation soil displacement field. The data terminal is set with displacement limits. When the sensor detects that the movement of magnetic particles in the soil exceeds the limit, the data terminal will issue an alarm signal to remind the monitoring personnel. The data terminal can be a mobile phone or a computer.

[0047] A method for monitoring low-damage road slope settlement, comprising the following steps:

[0048] 1) Technical preparation: Review the drawings and select a reasonable process, collect relevant information on the slope, and formulate corresponding protection measures for existing buildings that may be affected.

Along the road direction, set up a monitoring post 10 every 10-15 meters. For locations with loose soil and prone to settlement, the spacing can be shortened to a monitoring post 10 every 5-10 meters.

[0050] 3) Drill hole layout:

[0051] Construction is carried out at the pre-set installation points. The first drill bit 11 vertically drills the slope to form a monitoring hole. During the process of the first drill bit 11 drilling downwards, the second drill bit 2 is moved and extended every 4-5cm to drill side wall holes into the inner wall of the hole. After the drilling is completed, multiple side wall holes are set vertically in the monitoring hole.

[0052] 4) Magnetic powder introduction:

[0053] The magnetic powder is evenly introduced into the side wall hole, and sufficient magnetic powder is added into the monitoring hole. Then, the soil generated during drilling is backfilled into the monitoring hole.

[0054] 5) Installation of the detection system:

[0055] Install each component of the monitoring system on the monitoring column 10, set the initial value of the magnetic powder, install the power supply system, connect the power supply system and the monitoring system, connect the monitoring system to the data terminal, set the displacement limit of the magnetic powder on the data terminal, and complete the installation of the entire system.

[0056] 6) Real-time monitoring:

[0057] If the slope experiences vertical or horizontal displacement, the magnetic powder moves along with the soil. Sensor 3 monitors the displacement of the magnetic powder and sends the data to processor 4 for processing. The data is then transmitted to the data terminal via transmission module 5. The monitor judges the condition of the slope based on the information from the data terminal. When the magnetic powder offset exceeds the set displacement limit, the data terminal issues an alarm signal to remind the monitoring personnel to take timely emergency measures and perform timely maintenance.
