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.
