Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a sand and gravel waste material crushing device for construction engineering management. Background Art

[0002] Construction projects refer to the general term for various types of buildings and engineering facilities that provide the material and technical basis for human life and production. Construction projects are organized, purposeful, large-scale economic activities of human beings. According to their natural attributes, construction projects can be divided into three categories: architectural engineering, civil engineering, and mechanical and electrical engineering. They are engineering projects that form comprehensive production capacity or exert engineering benefits in the process of fixed asset reproduction. During the construction process of construction projects, a large amount of sand and gravel waste is usually generated. Sand and gravel waste can be reused after crushing.
