[0003] The foundations of the electrical secondary equipment cabinets in substations are conventional brick masonry. These cabinets are typically arranged in a linear array, with cable trenches between the rows. Each cabinet foundation typically utilizes a masonry structure, which refers to brick or block masonry mixed with concrete. The masonry structure in the cabinet foundation is simply a stack of red bricks and concrete. This structure takes a long time to construct, occupies a large construction area, is labor-intensive, and is susceptible to environmental constraints. It also involves extensive wet work, resulting in the generation of construction waste and wastewater, hindering energy conservation and environmental protection. Construction quality is also susceptible to the quality and capabilities of on-site personnel. With increasingly stringent safety controls and energy conservation and environmental protection requirements, the traditional on-site masonry construction model presents numerous drawbacks.
