Patent number: 7448827Abstract: A trussed embankment dam and wall structure includes a cantilever structure group and a rod member group, and each cantilever structure of the cantilever structure group includes an anchor supporting pillar and a multidirectional connecting board. The lower portion of the anchor supporting pillar is built at a stratum or foundation to support the cantilever structure, and the upper portion of the anchor supporting pillar installs a multidirectional connecting board to a trussed joint structure. After a force is exerted to a rod member of the invention, the force is acted onto the joints of the cantilever structure and transmitted by other rod members. Therefore, each cantilever structure maximizes the supporting effect and provides a dispersive supporting type structure. Unlike the centralized supporting type truss structure, the invention uses the hollow portion of the structure and the malleability of components to create landscapes, fill soil and plant vegetation.Type: GrantFiled: April 4, 2006Date of Patent: November 11, 2008Inventor: Piao-Chin Li
