[0002] A large amount of concrete is used in the construction of high-speed railways. The concrete is prepared using an intelligent mixing station. Before preparation, the sand and gravel required for the concrete grading need to be placed in the stacking site for classification and placement. When needed, loading equipment is used to pick up materials from the corresponding stacking site and send them to the feeding hopper of the mixing equipment.
