[0002] In the process of modern urban road construction, it is often necessary to groove the road to facilitate the laying of various line pipelines and sewer pipes. However, during road construction, there is still a need for road traffic, especially construction across intersections, but the construction cannot be completed in a short time. In particular, subway projects are often located in prosperous urban areas and have high requirements for transportation. In order to meet traffic and construction requirements, it is necessary to construct at night when the traffic volume is small and restore traffic during the day. The common method of restoring traffic is to lay steel plates above the grooves to facilitate the normal traffic of vehicles and pedestrians.

[0003] Protective steel plates have extensive and important applications in modern construction, but there are still certain inconveniences in their use. When protective steel plates are in use, they are usually transported and placed by forklifts, but the steel plates themselves are heavy and lack components that limit the position of the forklifts, resulting in the steel plates falling during transportation. In addition, when the grooves of the steel plates are too large, the steel plates lack adjustability, resulting in the need to replace steel plates of other sizes, which is inconvenient to use.

[0004] In view of the above-mentioned related technologies, the inventor believes that the protective steel plate has the defect of being inconvenient to carry and use;
