For example, during civil engineering construction, in order to ensure the flatness of the ground construction, a calibration ground rod will be used for leveling and positioning.

However, according to the above technical scheme, the calibration ground rod for civil engineering construction can only be inserted into the ground when in use, and it is not more convenient for construction workers to connect the thin wire. Construction workers need to manually wind it, and since the distance between the calibration ground rods is not equal each time when leveling, the thin wire needs to be cut frequently, resulting in unnecessary waste and greatly affecting the convenience of winding the thin wire of the calibration ground rod for civil engineering construction.

[0005] Therefore, those skilled in the art provide a kind of calibration ground rod for civil engineering construction to solve the problems raised in the above background technology. Utility Model Content
