AI Technical Summary
When expanding a power station, existing technologies require a large construction area and high costs for crossing cable trenches, and construction in other areas requires power outages, resulting in inconvenience and high costs.
A cable trench cover device for cable passage is provided. By constructing a second cable trench that intersects above the original cable trench, and using the original cable trench as a foundation, a cross structure is formed by an integrally cast cover and supporting wall. It can be quickly installed on site, adapts to different cable sizes, and reduces construction damage and costs.
It enables cable laying with short construction period, convenient operation and low cost, avoids cable crossing and entanglement and construction damage to the ground, reduces material and maintenance costs and improves maintenance convenience.
