Mechanical Principles of a New Two-Way Composite Disk Spring Cap for Pile Driving



The new two-way composite disk spring pile cap cannot only maintain the quality of construction but also improve pile-driving efficiency because the disk spring has both a high recovery coefficient and a high spring constant. In this paper the structural type, mechanical principles, composite disk spring mode of this kind of pile cap, and its pile-driving mechanism are introduced in detail. The results demonstrate that in order to obtain the optimum effect in pile driving one must properly choose the combination mode and compound stiffness of the composite disk spring.
