Abstract
Taking 30 m post-tensioning method prestressed concrete box beam prefabrication on Wangjiazhuang Bridge on Qing-Lin highway K111+065 as the example,it describes the main construction technology of on-spot prefabrication box beam,specifically expounds the planning construction,box beam prefabrication,and its stretching and pressure grouting and other aspects,which has certain guiding significance for future similar engineering.
