Study on the Characteristics and Reduction Measures of Construction Waste Generated in Subway Engineering

Abstract

Abstract In the process of urban modernization and rapid construction, the construction and reconstruction of large-scale construction projects such as subways, underground pipe corridors, and housing construction facilities are accompanied by a large amount of construction waste. A huge amount of construction waste not only occupies a large number of land resources, but also affects air quality, pollutes waters, destroys city appearance and environmental sanitation, and has potential safety hazards. In the long run, it also affects urban development space and shortens the city life cycle. At present, there are many shortcomings in China’s policy management, classification and measurement, reduction technology, transportation recovery, recycling and other aspects of construction waste. Especially from the source, there is a lack of research on the source characteristics of construction waste, which makes the quantitative quantification of various construction wastes impossible to achieve construction, accurate management, and control of waste. This study takes the urban subway construction project as the research object, through the field investigation, literature review and other methods, analyses the classification and source of underground construction waste by the project unit construction process as the framework, and analyses the corresponding construction waste according to the investigation and data collection. The reduction measures implemented.
