Ltd. Hangzhou Zhejiang 320000 China Abstract:Concrete pile cap crane foundation with steel embrace loop pile is a new type of crane foundation structural system.It consists of concrete pile cap screw holes filling pile and the steel embrace hoop on pile shaft.Similar to steel pipe piles crane foundation this crane foundation structural system not only can provide vertical and horizontal transportation machinery for casting concrete slabs and soil excavation but also can increase the work radius of crane tower which results less construction time and higher efficiency.Compared with other construction technologies the construction technology is featured by simpler operation more reasonable design.It also obtains the advantages of as low cost and recyclable.
