Electrically operated roller shutters must rely on technological progress and development to ensure bridge safety while accelerating bridge construction. It should be etched in the minds of every bridge worker. An effective and direct method for the bridge's completion and acceptance inspection is to use color steel plates for wall and roof closure above 21.00 meters, equipped with a material unloading chain hoist at the roof, with a storage capacity of 110,000 tons.

The electric sliding canopy proposal has the following advantages and disadvantages:

High efficiency and scalable for mass production: The solution utilizes equipment for both input and output materials, ensuring high efficiency and adaptability to large-scale production needs, with a substantial storage capacity per unit area.

(2) Increased steel consumption in reinforced concrete and steel structures: Due to the taller walls and larger diameter of the silos, the walls are under greater stress, resulting in a larger amount of reinforced concrete used in the walls. The upper space steel structures have a larger span and load, leading to a higher steel consumption per square area.

(3) In addition to regular inspections and maintenance, workers do not come into contact with dust, which is beneficial for labor protection.

The electric sliding canopy scheme for winter storage of熟料 heaps, tailored to the technological characteristics of winter storage sheds, boasts a significantly lower construction cost (per ton of熟料 stored) under the adoption of reliable and reasonable labor protection measures. The top features a space steel structure (steel grid or truss), supported by independent supporting columns at the bottom, and retaining walls around the perimeter. Moreover, the processing and manufacturing of the space steel structure, along with on-site assembly, results in a shorter construction period, making it particularly suitable for areas in Northeast China with fewer "golden construction months."
