Therefore, the prefabricated pile foundation emerges as the times require, but the prefabricated pile foundation is mostly constructed by using large gravity equipment hammering or static pressure construction. Since the hammering or static pressure load is large during construction, the top surface levelness of the pile foundation cannot be accurately controlled, and the poor levelness precision easily leads to the serious consequences that the tower assembly is not smooth or even cannot be assembled in the later period.
