Abstract: An ecological board includes a quadrilateral board body, on the side edges thereof is disposed at least one reglet or at least one insertion groove to be engaged with a corresponding insertion groove or a reglet of another identical board body. Further, a plurality of separated strong and pliable pad bodies are embedded in at least a first side surface of the board body and protrude outwards therefrom. The ecological board according to the present invention is durable, stable, easy to construct, maintain, and repair, and environmentally friendly to the natural landscape. Most importantly, it can be applied to various environments, such as coastlines, artificial reefs, and slopes of reservoirs, rivers, or mountains.

Abstract: A protection barrier includes a base, the base having a great lower side and a small topside; the base expanding from the topside to the lower side gradually; each of two lateral sides of the base being installed with a first buffer for buffering and resisting impacts from vehicles. The base has an approximate triangle shape with each apex being frustrated. Each of the two lateral sides of the base having a second buffer. A ground anchor is installed to a bottom of the base. The buffers have a shape selected from semi-round shapes, semi-elliptical shapes, and other cambered shapes. The protection barriers can be arranged longitudinally between two lanes for isolation or aside a lane for preventing a vehicle to run out of the lane.

Abstract: A retaining wall for water and soil conservation use a plurality of stacking retaining plates. Each of the retaining plate has a plurality of inner protrusions at an inner side thereof. The protrusions of the lower retaining plate of the stacking retaining plates grab the soil at the bottom of the slopeland so as to form a steady retaining structure. The method for performing the water and soil conservation by the wall is also disclosed.
