摘　　要：深圳宝安国际机场卫星厅及配套工程建设过程中,产生巨量混凝土固体废弃物。在外运成本高昂、环保政策高压的环境下,通过集成减量化破碎、全自动压砖、再生碎石混凝土及水泥稳定集配等核心技术,将既有混凝土结构、内支撑、桩头等建筑固体废弃物,破碎筛分转换为可回收利用的废旧钢筋、再生免烧砖、再生碎石混凝土及水泥稳定碎石基层等,成功解决巨量建筑垃圾处理成本高、利用率低等难题,实现环境保护和资源再生利用,初步达到建筑固体废弃物零排放的目标。During the construction of the satellite hall of Shenzhen Bao'an International Airport,a huge amount of solid concrete waste was generated.Under the high cost of export and high pressure of environmental policies,the existing concrete structure,internal support,pile head and other solid building waste were crushed and screened into the recyclable waste steel bars,recyclable unburned bricks,recyclable rubble concrete and cement-stabilized crushed-stone base through the integration of reducing crushing,automatic brick pressing,recycled crushed stone concrete and cement-stabilized assembly and other technologies.The problems of high cost and low utilization rate of huge amount of construction waste treatment has been solved successfully,environmental protection and resource recycling has been realized,and the goal of zero emission of solid waste has been basically achieved.
