Coal shed grid

Generally speaking, the main function of the dry coal shed grid structure is to cover the coal yard to prevent the coal from being drenched when it rains and polluting the environment when it is windy. It is an energy saving and environmental protection project. The architectural function of the dry coal shed is mainly a large storage warehouse. Therefore, it must have a certain storage and working space, that is, the structure must meet certain clearance requirements, and the cross-sectional shape of its effective space is trapezoidal, and the envelope of the working space is close to an arc. The length and width of the dry coal shed grid structure are determined according to the needs of installed capacity, and the height of the structure is determined by the operation requirements of coal stacking and bucket wheel machines. Therefore, the characteristics of the dry coal shed structure are large span, high height and wide coverage area.
