Measuring and reading device for a water and soil erosion survey pin and using method thereof

Abstract

The invention discloses a measuring and reading device for a water and soil erosion survey pin. The measuring and reading device comprises a movable outer barrel and a guide inner barrel arranged inside, which are in sliding connection, wherein a limiting top cap is arranged above the top end of the guide inner barrel; a back cover is arranged at the bottom end of the guide inner barrel; the guide inner barrel and the movable outer barrel are equal in length; scales are formed in the guide inner barrel; the outer diameter of the guide inner barrel is greater than the outer diameter of the survey cap. The invention further discloses a using method for the measuring and reading device for the water and soil erosion survey pin. The measuring and reading device has the characteristics of being operated outdoors, capable of avoiding artificial interferences, accurate in reading, simple in structure, easy to grasp, low in using cost, reliable in performance, and the like. Compared with the conventional survey pin with the scales, the measuring and reading device can be used for overcoming the defects that the scales on the survey pin are easy to peel off, the rust corrosion is polluted, the reading is difficult, the efficiency is low, the requirements for the survey pin processing process are high, the cost is high, and the like.

Description

technical field [0001] The invention belongs to the technical field of soil and water conservation monitoring facilities, in particular to a soil erosion measuring reading device and a method for using the same, which are applied to accurate reading and collection of measuring data in the measuring method for monitoring water and soil loss. Background technique [0002] As a global ecological problem, soil erosion has been paid more and more attention. How to effectively measure and control soil erosion has become the focus of widespread attention in all countries. In the construction of water and soil conservation and forestry ecological environment, the primary task is to monitor water and soil loss, provide quantitative monitoring data of water and soil loss for the regional ecosystem, predict the trend of regional water and soil loss, and then know a certain amount before and after the rainfall. The situation of soil erosion in the area can be controlled and protected in...

AI Technical Summary

Problems solved by technology

[0006] (1) Use a common measuring rod with a scale as the measuring rod. The measuring rod scale is easy to rust and peel off in the outdoor environment, resulting in data loss

[0007] (2) Due to the short scale of the exposed slope surface of the measured brazing, it is difficult for data collectors to read, and it is easy to increase the reading error due to the difficulty of viewing the line of sight

[0008] (3) The traditional measuring drill is usually hammered into the slope surface. Due to the certain flexibility of the measuring drill, it tends to become shorter under the action of hammering, resulting in smaller scale intervals on the measuring drill and inaccurate scales.

[0009] (4) It is necessary to measure the reading with the help of a ruler sticking to the ground. While the reading is difficult, it also increases the workload, resulting in low data collection efficiency
