Description

technical field

The utility model relates to the technical field of measuring drill, in particular to a measuring drill for measuring the amount of water and soil loss.

Background technique

Soil erosion is one of the important factors causing ecological damage and land degradation, which can induce ecological environment deterioration, aggravate natural disasters, poverty and many other problems. China is one of the countries with the most serious soil erosion. The national soil erosion area is 4.92 million km ² , accounting for 51.2% of the country's land area. Among them, the water erosion area is 1.79 million km ² , the wind erosion area is 1.88 million km ² , and the freeze-thaw erosion area is 1.25 million km 2 . 10,000 km ² , the environmental problems caused by soil erosion are very serious, so the real-time and accurate monitoring of the development of slope erosion gully and the changes of micro-topography in aeolian sandy areas is of great significance to the prevention and control of soil erosion and desertification in China;

At present, the commonly used soil erosion measurement methods are mainly divided into traditional measurement methods and advanced instrument measurement methods. The traditional measurement methods mainly include the observation method of the erosion ditch, the drilling method, the filling method, and the measuring ditch method. Advanced instrument measurement methods mainly include rare earth element tracing method, radionuclide tracing method, real-time dynamic measurement technology of high-precision GPS, three-dimensional laser geomorphological analysis and aerial photography technology. Traditional measurement methods are widely used in the process of soil erosion monitoring, and are easy to set up and operate. Among them, the drilling method is a common method for soil erosion monitoring in development and construction projects, and has been included in the technical regulations for soil and water conservation monitoring. However, the traditional soil erosion measurement methods also have many shortcomings, such as the instability and damage of the measurement points, the heavy installation workload, poor measurement accuracy, and the lack of intuitive response of the measurement data accuracy range to the dynamic process of soil erosion, etc. ; With the advancement of science and technology, the use of advanced instruments in soil erosion measurement has gradually increased. The use of advanced instrument measurement methods has high measurement accuracy, strong real-time performance, and can also save a lot of manpower and material resources. However, advanced instrument measurement methods are difficult to carry out monitoring in areas with complex terrain, such as sloping land covered by dense vegetation and desert hinterland, due to the difficulty of carrying instruments and deploying them. For the remote sensing image monitoring method, due to insufficient resolution and other problems, it is difficult to reflect the change process at the micro-scale, and it is not suitable for application in actual monitoring work. In addition, the advanced instruments still have disadvantages such as high cost, difficult to master the technology, and inconvenient to carry the instruments. Regarding the tracer method, both the operation process and the preparation and analysis of soil samples require high costs, and the research cycle is long, which brings a lot of inconvenience to the experimental analysis work.

To sum up, for the development of slope erosion gully and the monitoring of micro-geomorphic changes in sandy areas, both traditional measurement methods and advanced instrument measurement methods have their own drawbacks. , The measurement accuracy is higher than the integrated soil erosion observation device. Therefore, the utility model provides a measuring tool for measuring the amount of soil erosion, so as to solve the above-mentioned problems.
