Precast concrete tube sheets are increasingly used in tunnel construction,which consumes a large amount of resources and energy and releases a large amount of greenhouse gases during the construction process.It has been found that the precast component production stage has the largest carbon emission,and it is of great significance to reduce the carbon emission in the precast component production stage,however,little research has been done on the carbon emission in the precast concrete tube sheet production stage.Taking precast concrete pipe pieces in tunnel engineering as an example,we propose a carbon emission calculation model for precast concrete pipe pieces in the production and transportation phases of precast factories and calculate the carbon emissions in each phase,so as to provide theoretical basis and reference for energy-saving and emission reduction strategies of precast concrete pipe pieces.
