Application Of Hydraulic Synchronous Erection Technology In Projects

Following the mushrooming of the big-span building and skyscraper in China,the traditional erecting technology can not resolve facing difficulties sometimes.It is necessary for new erecting technology.The hydraulic synchronous erection technology as an rising hi-tech erecting technology is applied and caught more attention in steel structure erecting domain.In the base of engineering practice,the study raises a whole set of outline of construction technology for hydraulic synchronous erecting,and some key points for construction process.Compareing the different towing equipment used in sliding construction,summing up the key technology points in the construction technology preparing and sliding process.Combining the application process of Wukesong basketball gymnasium sliding technology,proposing the principle of maximum static friction force calculation in the towing process and the choice of synchronous controlling way and the arch camber limitation of in the middle span and the way to clear the assemlying secondary stress.Studying the technology designing steps of hydraulic uninstalling technology. Describing the designing process of the technology flowing to hydraulic lifting and hydraulic sliding and hydraulic uninstalling.It provides the construction basis and experience to following projects.
