Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of soil and water conservation monitoring, and in particular relates to an erosion needle monitoring structure. Background Art
[0002] The simple soil erosion observation field method is a ground monitoring method for soil and water conservation monitoring in development and construction projects. This method uses erosion needle monitoring samples for observation and measurement. It is suitable for soil erosion observation of scattered soil deposits in the project area and soil deposits that are not convenient to set up communities or control stations. The site selection should choose slopes of different types of soil deposits and avoid the influence of surrounding water. Before the flood season, steel drills with a diameter of 0.5~1.0cm and a length of 50~100cm are arranged in 3 rows and 9 pieces at a certain distance vertically and horizontally. The steel drills are driven vertically into the slope along the plumb bob direction, and the nail caps are flush with the slope. When the slope area is large, the steel drills are denser and the slope slope is measured by the slope meter. After each heavy rain and before and after the flood season, the soil erosion thickness and the total soil erosion amount are calculated by observing the height of the nail caps from the ground. The calculation formula used is: A=ZS / 1000cosθ, where: A is the amount of soil erosion (m3), Z is the erosion thickness (mm), S is the horizontal projection area (m2), and θ is the slope gradient.
[0003] This method is widely used in soil and water conservation monitoring, but in actual deployment, the original method has the following shortcomings: there is no scale on the steel bar, and after each steel bar is driven into the slope, a steel tape measure is used to measure the height from the nail cap to the slope, resulting in large errors in the measurement process; the regularity of the sample plot is not easy to operate and control; the operation process is relatively complicated during the sample plot deployment process, and the artificial disturbance to the slope is relatively large, affecting the measurement accuracy; the simple observation field is basically located on the slope, especially on the steeper slope, and there are certain safety hazards in long-term deployment and measurement; many monitoring tools are required, which are messy and difficult to organize. Utility Model Content
[0004] The utility model provides an erosion needle monitoring structure, which aims to arrange monitoring points more simply, safely, portablely and accurately, thereby improving work efficiency.
[0005] An erosion needle monitoring structure, characterized in that it includes a needle and a nylon wire, wherein the needle is cylindrical, with a total length of 65 cm, a diameter of 1.0 cm, a wire binding groove 9 cm away from the top, a wire binding groove width of 1 cm, a scale line with a total scale of 50 cm, and a rigid pointed cone with a length of 5 cm at the lower end. Nine needles are evenly arranged in three vertical and three horizontal directions, with a vertical and horizontal spacing of 1 m. Nylon wire is wrapped around the wire binding groove to connect the eight needles on the periphery in sequence to form a square, and then the needle in the center is connected to the needles at the four corners through the nylon wire.
[0006] Furthermore, when the soldering needles are not installed, all the soldering needles are gathered together and tied into a bundle by adhesive tape, which is convenient for carrying and transporting.
[0007] Furthermore, the smallest scale of the scale lines is in cm, and the dimensions marked from bottom to top are -30cm, -20cm, -10cm, 0cm, 10cm, and 20cm.
[0008] The beneficial effects of the utility model are that the needle is fixed by wrapping with adhesive tape before unfolding, which is convenient for carrying and avoids scattering and tangling. The adhesive tape is opened before work, and after the device is initially unfolded, the needles can be embedded one by one to complete the layout. No tape measure is required, which is convenient for data reading and reduces human measurement errors, thereby reducing frequent human disturbances in and around the sample plot, which may lead to damage to its geomorphic factors.

[0013] Embodiment 1: An erosion needle monitoring structure, including a needle 2 and a nylon line 1. The needle 2 has a total length of 65 cm and a diameter of 1.0 cm. A wire binding groove 3 is set 9 cm from the bottom, and the width of the wire binding groove 3 is 1 cm. A scale line 4 with a total scale of 50 cm is set in the middle section, and the smallest scale is in cm. The dimensions from bottom to top are marked as -30 cm, -20 cm, -10 cm, 0 cm, 10 cm, and 20 cm. The lower end is a rigid cone 5 with a length of 5 cm, which is convenient for the needle 2 to be inserted into the soil. When the needle 2 is not installed, all needles 2 are gathered and tied into a bundle with adhesive tape to facilitate carrying and avoid scattered knots. Before work, open the adhesive tape, and after preliminary expansion, insert the needles 2 in sequence. Expand the nine needles 2 and insert them into the soil deposits to form a 2m*2m matrix. Three needles 2 are set in each row and column, and the vertical and horizontal spacing is 1m. Use nylon wire 1 to wrap in the wire groove 3 to connect the eight needles 2 on the periphery in sequence to form a square, and then connect the needle 2 in the center with the needles 2 at the four corners through the nylon wire 1. The nine needles 2 are nailed to the same scale and recorded for easy data reading.
