[0002] In bridge construction, people often use mold brackets as supports first, and then cast concrete to form a bridge. The concrete waste material processing device for bridge construction is used to process the concrete waste material for bridge construction. The concrete waste material is the concrete material left after the completion of the bridge construction. Concrete refers to the general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as cementitious material, sand and stone as aggregates; and water (which may contain admixtures and additives) in a certain proportion, and the cement concrete obtained by mixing is also called ordinary concrete, which is widely used in civil engineering.

[0003] During the construction of bridges, a lot of waste materials are generated. The waste materials inside the concrete mixer are usually not used, which will waste construction resources and increase construction costs. If they are not recycled, the concrete will solidify into a solid block, which will seriously affect the subsequent recycling of the equipment.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a concrete waste material recovery device for bridge construction is proposed. Utility Model Content
