The lattice unit includes a convex tenon and a concave tenon groove disposed at an end of the lattice and connected with each other through two or more pre-molded components to form a tenon-and-groove structure, such that the protruded tenon between the components can be embedded into a tenon joint assembly in an adjacent tenon groove for connecting the components in series to form a continuously extended lattice unit. The continuous structure of lattice units forms a plane layer of a space lattice structure. The combining pillar is passed perpendicularly through the hollow portion of the component for connecting the plane layers of the lattice units along the direction of the height of the structure to form a three-dimensional space lattice structure. A heavy filling material is filled into the hollow portion of the structure to form a gravity structure, and a combining pillar is piled into a stratum or foundation to form a cantilever structure, so that the pace lattice structure becomes a multifunctional structure for earth retaining, water drainage, and earth fill vegetation. ## Claims ### Claim 1 A tenon joint type space lattice structure, comprising a predetermined quantity of lattice units and combining pillar, characterized in that: a) the lattice unit comprises two or more pre-molded components coupled with each other, and a convex tenon and a concave tenon groove disposed on an end of the lattice unit, and the tenon and the tenon groove form a tenon-and-groove structure, such that the tenon protruded between each component is embedded into an adjacent tenon groove and coupled with the tenon groove by a tenon joint assembling process, and the components are coupled with each other in series to constitute a continuously extended lattice unit;
