in engineering construction, the application range of cold-formed steel sheet piles is relatively narrow, and most of them are used as supplementary materials for applications. hot-rolled steel sheet piles have always been the leading product for engineering applications. based on the many advantages of steel sheet piles in construction operations, the general administration of quality supervision, inspection and quarantine of the people's republic of china and the national standardization management committee issued the national standard for "hot rolled u-shaped steel sheet pile" on may 14, 2007, and on december 1, 2007 formally implemented. at the end of the 20th century, maanshan iron & steel co., ltd. produced more than 5,000 tons of u-shaped steel sheet piles with a width of 400mm with the introduction of the universal rolling mill production line from abroad. the u-shaped steel sheet piles were successfully used in the cofferdam of nenjiang bridge and the 300,000 tons of jingjiang new century shipyard. ton shipyard and bangladesh flood control projects. however, due to the low production efficiency, poor economic efficiency, low domestic demand and insufficient technical experience during the trial production period, continuous production was not possible. according to statistics, the annual consumption of steel sheet piles in my country remains at about 30,000 tons, accounting for only 1% of the world’s total, and it is limited to permanent projects such as the construction of some ports, wharves, and shipyards, as well as the construction of bridges, cofferdams, and foundation pit support temporary works.
