Design and construction of Self-elevating tower crane pile foundation of a high building

In view of the application characteristics of Self ?elevating tower cra ne of a high building, design, construction, and removal of tower crane pile fou ndation are discussed in detail. The design method of pile type of the tower cra ne base which is identical with engineering pile type are put forward. At the sa me time, load calculating and the questions ought to be paid attention to are re serched, therefore, it reaches the effect of economy and safety. Thus both basal design drawing of the produce factory effectively used in on?the?spot removal /fitting and the great load difference in work and non?work status are settled.
