Modular design and processing technology of metal templates for ultra deep and ultra large cross-section vertical shafts
In recent decades,the promotion and development of metal formwork(hereinafter referred to as"steel formwork")has been one of the main signs of the improvement in the mechanization level of shaft construction.The bulky wooden formwork has been replaced by economical and durable steel formwork.With the development of construction in the direction of ultra deep and ultra large sections of shafts,the strength and demoulding reliability of steel molds used for shaft formwork are also facing great challenges.Based on the company's winning bid for the construction of a domestic metal mine's ultra deep and ultra large section auxiliary shaft project,we have explored the modular design and processing technology of steel molds and achieved good results.Compared with traditional processing technology,the construction period has been reduced from 90 days to 60 days,achieving rapid construction of shaft wall pouring concrete and excellent engineering quality.
