There is still much room for improvement in effectively utilizing limited space, reducing the impact on the natural environment, and improving construction and maintenance efficiency.

[0003] For example: although direct burial of cables saves materials and labor, the covering soil needs to be dug up for maintenance, resulting in complicated operations and low efficiency when maintenance is required; although cable tunnels are relatively convenient for maintenance and inspection, the one-time investment is large, the excavation area is large during construction, and the damage to the surrounding environment is greater.

[0004] In addition, in some factory areas, power plants, substations and other areas with complex construction conditions and many underground obstacles, cables cannot be laid underground. Therefore, providing a cable ground bracket with a reasonable structure and easy installation has become an urgent problem to be solved. Utility Model Content
