Abstract: The demolition construction scheme of large stadium represented by Beijing Workers Stadium was studied. Theselection and construction technology of the demolition of stadium in China at the present stage were discussed. Based onthe analysis of the concrete strength of each part of main structure to be dismantled and the structure form of annexbuilding,the zero emission technology route of construction waste was proposed based on classified disposal and reuse. Fineseparation and functional utilization technology was adopted based on high hybrid characteristics of brick and tile waste.According to concrete garbage of different strengths, the high value utilization technology of classification disposal was usedto optimize the economic benefit of classified disposal. The construction waste classification and reuse technologies such asbrick and tile recycled aggregate technology, flow backfill material technology, recycled concrete products developmenttechnology, recycled road materials development technology were studied. The construction waste recycling was realized byusing the pre-mixed flow curing in fertilizer trough backfilling of stadium and using recycled concrete in statium table boardof prefabricated components and municipal bricks.

Keywords:construction waste; green building; sponge city; zero emission; classification and reuse
