Technical Field
The utility model belongs to building waste handles the field, specifically discloses a building discarded object classification device.
Background
The construction waste refers to construction waste generated by human or natural reasons in engineering, and comprises waste residue soil, waste soil, silt, waste materials and the like. These materials are not helpful to the construction itself, but are substances generated in the construction process, and need to be treated correspondingly, so that the ideal engineering project construction can be achieved, and because the materials are an integral process, the link consideration is more important.
At present, the main treatment method of the construction waste in China is to bury the construction waste underground. The harm is as follows:
firstly, a large amount of land is occupied. Only by taking Beijing as an example, the following data are shown: in the prior removal of the original building before the construction of the Olympic project and the construction of a new construction site, twenty-thirty building garbage disposal sites are required to be arranged every year in Beijing, which causes little land pressure.
Secondly, causing serious environmental pollution. The construction glue, coating and paint in the construction waste are not only high molecular polymer materials which are difficult to biodegrade, but also contain harmful heavy metal elements. The waste is buried underground, which causes pollution of underground water and directly harms the life of surrounding residents.
Again, the soil structure is destroyed, resulting in surface subsidence. The current landfill method is: after 8 m of garbage is buried, 2 m of soil layer is buried, but basically vegetation is difficult to grow on the soil layer. The surface of the landfill area is settled and subsided, and a stable state can be achieved after a long time
The construction waste is not real waste, but "gold" of the place is misplaced, and after being sorted, rejected or crushed, most of the construction waste can be reused as renewable resources, such as: the waste steel bars, waste iron wires, waste electric wires and other metals can be processed into steel products with various specifications after being sorted, concentrated and recycled; the waste bamboo and wood can be used for manufacturing artificial wood; the waste materials such as bricks, stones, concrete and the like can be used for replacing sand, building mortar, plastering mortar and the like, and can also be used for manufacturing building material products such as paving bricks, lattice bricks and the like.
