MULTISTAGED CONE FOUNDATION

摘要

A multi-layered cone foundation is provided to reduce the number of piles by integrally forming an upper foundation and a lower foundation and prevent the ground from being excessively excavated in order to enlarge the cross section of the foundation. A multi-layered cone foundation comprises a post(100), a lower foundation(200), a middle foundation(300), and an upper foundation. The upper foundation is composed of a fixing plate, a supporting frame, aggregate or concrete. A groove is formed at one side of the fixing plate. A through rod(110) of a post is inserted into the groove. The supporting frame is formed in a grid shape. In the supporting frame, a fixing plate is installed. The internal space of the supporting frame is filled with the aggregate and the concrete. The upper foundation supports the upper structure.
