[0025] Example 1
[0026] Such as figure 1 The shown pre-installed ground wire fastening device aims to provide a prefabricated ground wire installation and fastening device that simplifies the existing operation process. The specific design structure, principle and work flow are described below.
[0027] The outer cylinder 1 and inner cylinder 2 of this device are the installation bases. In the prior art, when the grounding wire is used, the soil resistivity should be measured first, and then the grounding trench should be set out according to the design drawing requirements and the site topography and landform conditions, and the excavation line of the grounding trench should be drawn. The device can determine the length of the outer cylinder 1 and the inner cylinder 2 according to the resistivity of the soil to determine the grounding safety. Such as image 3 As shown, the outer cylinder 1 is movably mounted on the inner cylinder 2. A fixing groove 14 is provided on the outer ...
