Description

Technical Field

[0001] The utility model relates to the technical field of highway engineering detection, in particular to a device for quickly measuring the slope ratio of a roadbed side slope. Background Art

[0002] The slope ratio of road embankment refers to the ratio of the vertical height to the horizontal width of the road embankment slope. It is an important indicator to measure the stability and safety of the road embankment slope. During road construction and maintenance, the road embankment slope ratio needs to be accurately measured to ensure the safety and stability of the road.

[0003] At present, the commonly used methods for measuring the slope ratio of road embankment slopes mainly include the level method, total station method, steel ruler method and laser scanning method. The level method requires setting up multiple observation points on the slope and using the level to measure point by point. This process is time-consuming, especially when the slope area is large or the terrain is complex, and the efficiency is low. The level method may not be able to measure under severe weather conditions, such as heavy rain and strong wind, or the accuracy of the measurement results will be affected. Since the level needs to be manually operated and moved between different points, the physical strength requirements of the operator are high and the labor intensity is high. When using the level to measure on steep slopes or slopes with complex terrain, there are certain safety hazards. Especially when working at high altitudes, the level method has high requirements on the technical level and experience of the operator. Improper operation can easily lead to measurement errors. The measurement process of the level method is difficult to automate and requires manual reading and recording of data, which limits its application in large-scale data measurement. Compared with traditional measurement methods, high-precision levels may require higher purchase and maintenance costs. The data collected by the level method requires manual processing and calculation at a later stage. This process is cumbersome and time-consuming. The level method usually needs to be operated on the slope site, and it is difficult to achieve remote monitoring and real-time data acquisition. Although these methods can meet the measurement accuracy requirements, they have problems such as complex operation, low efficiency, and high cost.As a high-precision surveying equipment, the purchase and maintenance costs of the total station are relatively high. The operation of the total station is relatively complicated and requires professional surveying personnel to operate it. There are certain requirements on the technical level of the operator. The measurement of the total station may be affected by weather conditions. For example, bad weather such as fog, rain, and snow may reduce the accuracy of the measurement. In an environment with complex terrain or obstructions, the measurement of the total station may be limited by line of sight, affecting the continuity and comprehensiveness of the measurement. Although the total station can automatically record data, the post-processing and analysis of the data still requires professional software and a certain amount of time. Equipment carrying and setting: The total station and its accessories are usually bulky and need to be set up and calibrated at the measurement site, which may increase the workload. The total station requires a stable power supply, and long-term field operations may require additional power support. When using a total station for measurement on steep or unstable slopes, there may be a risk of equipment damage or personnel safety. Although the total station can be The steel ruler method can be used to measure quickly, but for some application scenarios that require high-frequency monitoring, it may still not meet the needs of real-time monitoring; the accuracy of the steel ruler is limited, and it is easily affected by human factors during the measurement process, such as reading errors, steel ruler stretching or bending, etc., resulting in low accuracy of the measurement results; the steel ruler method requires multiple measurements and calculations on the slope, and the operation process is cumbersome and requires certain skills and experience. Due to the need for multiple measurements and records, the measurement efficiency of the steel ruler method is low and it is not suitable for large-scale slope ratio measurement. When measuring the slope ratio, the surveyor needs to operate close to the edge of the slope, which poses certain safety risks, especially on high or unstable slopes. The steel ruler method may not be applicable to complex terrain or difficult-to-reach areas, and cannot perform accurate measurements. The steel ruler method can only provide static measurement results and cannot monitor the changes in the slope ratio in real time; laser scanning, laser scanning is a non-contact measurement method that does not cause any damage to the slope. This is very important for some slopes that need to be protected or difficult-to-reach areas. Laser scanning can adapt to different measurement environments and conditions, such as complex terrain, bad weather or night. This solution adopts the laser scanning method, which uses laser scanning to detect the length from the laser detector to the slope. After the vertical direction is confirmed by the support rod of the scale, the slope ratio of the slope is calculated through two vertical lines.

[0004] The patent is published, the patent name is a water conservancy project slope ratio detection device, the patent number is 202223324184.6. In the above scheme, the stability of the equipment may be affected during the measurement process. For example, the moving wheels may shake on uneven ground, resulting in inaccurate measurement results. The motor needs to be operated to lower the counterweight, which increases the complexity of the operation. For slopes with different slopes and terrains, the adaptability of the device may be limited.

[0005] The patent number is CN201921297828.2, and the name of the patent is a device for rapid detection of the slope ratio of highway slopes. The solution can make the slope detection process of highway engineering slopes simple to operate, save time and effort, effectively improve the detection progress and ensure the accuracy of the detection data. The overall space occupied by the detection device becomes smaller, it is easy to carry, and it is practical. At the same time, it can effectively prevent the wear of the surface of the reflective substrate, increase its service life, and reduce the vibration of the reflective substrate during carrying, and has a good protective effect. However, when in use, the extension rod is movably connected to the reference rod through the limit ring. Precise manual operation may be required to ensure accurate centering, which increases the complexity of the operation. Frequent use or improper use of force may damage the limit ring and affect the connection stability of the extension rod and the reference rod. The placement position and angle of the reflective substrate need to be accurate, otherwise it may affect the accuracy of the laser ranging, and the operation is complicated; the extension and adjustment of the centering rod may require certain operating skills. If it is improperly adjusted or not fixed firmly, it may cause inaccurate centering and affect the measurement results. Utility Model Content

[0008] The beneficial effects of this solution are: the use of the laser measuring mechanism and the level sensor can quickly obtain relevant data of the slope, greatly reducing the time and manpower required for traditional measuring methods; the level sensor can help ensure that the device is in a horizontal state during measurement, thereby improving the accuracy of the measurement; the movable matching connection between the support rod and the fixed plate and the matching connection between the support platform and the support rod allow the device to be adjusted as needed, which is convenient for carrying and measuring at different positions; the slope ratio detection can be carried out through the support rod and the measuring mechanism, and the operation is simple.

[0009] Furthermore, a groove is provided at the laser hole, the diameter of the groove is larger than the diameter of the laser hole, and the laser hole is provided at the center of the groove.

It can block part of the stray light, improve the purity and accuracy of the laser signal, and set the laser hole at the center of the groove, making it easier for the operator to align and adjust the direction of the laser head. The groove can protect the laser head from external collision or damage to a certain extent, and it can prevent the laser head from being directly hit by external objects, thereby extending the service life of the laser head.

[0010] Furthermore, the support rod is a retractable support rod. By adjusting the length of the support rod, the device can be adapted to different height measurement positions. This is very useful for measuring slopes of different slopes and terrains, ensuring that the laser head can accurately align with the measurement target. When not in use, the support rod can be shortened to make the device more compact and easy to carry and store. This is very convenient for work that requires frequent movement and measurement in different locations.

[0011] Furthermore, a ruler is provided on the support rod, which allows the operator to directly read the length or height of the support rod without using other measuring tools. This is very convenient when it is necessary to quickly obtain dimensional information, such as measuring the height or distance of a slope. By reading the scale on the ruler, the operator can accurately adjust the length of the support rod to meet specific measurement requirements, which helps to quickly locate and align the measuring point and improve work efficiency.

[0012] Furthermore, the support table is configured as a flip-foldable structure, which can be folded up when not in use, reducing the space occupied and facilitating carrying and storage, which makes the device easier to transport and store. The process of folding and unfolding the support table is relatively simple and can be easily completed by the operator without the need for complex tools or skills, which makes the device easier to use and operate.

[0013] Furthermore, a solid steel cone is fixedly provided at the lower end of the support rod, and the solid steel cone can be inserted into the ground or other supports to provide a more stable support point. It can prevent the support rod from sliding or tilting during use, thereby ensuring the accuracy and reliability of the measurement. Solid steel usually has higher strength and wear resistance, and can withstand long-term use and frequent insertion operations, which helps to extend the service life of the support rod.

[0014] Furthermore, a horizontal limit plate is provided at the connection between the new steel cone and the support rod. The horizontal limit plate can prevent the support rod from excessively sinking or tilting when inserted into the ground, providing additional support and stability. It helps to maintain the vertical position of the support rod and ensure the accuracy of the measurement. The horizontal limit plate can limit the depth of the new steel cone inserted into the ground, avoiding excessive insertion that makes it difficult to pull out or damage the steel cone. It helps to control the insertion depth and make the measurement operation more convenient and controllable.

[0015] Furthermore, a protective cover is provided on the laser hole, and the protective cover is fixed on the groove through a rotating shaft. The protective cover can effectively block direct contact of foreign objects with the laser hole, reduce the risk of scratches, collisions or dust entering the laser hole, thereby protecting the optical performance and precision of the laser hole. By protecting the laser hole and reducing potential damage and pollution, the service life of the laser equipment can be extended and the maintenance and replacement costs can be reduced. At the same time, the rotating connection makes the protective cover more convenient to operate when rotating. BRIEF DESCRIPTION OF THE DRAWINGS
