Environment protective liner plank structure having several legs and a panel. Each leg is composed of multiple layers of rice grasses (or wheat stems) which evenly overlap each other in the same direction. A layer of adhesive is sprayed between each two layers of rice grasses (or wheat stems). When each layer of rice grasses (or wheat stems) is evenly overlaid on a lower layer of rice grasses (or wheat stems), a male mold is used to compress the rice grasses (or wheat stems) into a compact state. The lowermost layer of rice grasses (or wheat stems) of the panel is evenly overlaid on the adhesive on the uppermost layer of rice grasses (or wheat stems) of the leg. A plane board mold is used to compress the rice grasses (or wheat stems) into a compact state. A layer of adhesive is sprayed over the lowermost layer of rice grasses (or wheat stems) of the panel and then an upper layer of rice grasses (or wheat stems) are overlaid on the lowermost layer of rice grasses (or wheat stems). Then, the plane board mold is used to compress the layer of rice grasses (or wheat stems). Such procedure is repeated until the panel of the rice grasses (or wheat stems) has a certain thickness.
An environment protective liner plank structure having several legs and a panel, said environment protective liner plank structure being characterized in that each leg is composed of multiple layers of rice grasses or wheat stems compressed into a compact state by a male mold and which evenly overlap each other in the same direction with a layer of adhesive between each two layers of rice grasses or wheat stems, the lower most layer of rice grasses or heat stems of the panel being evenly overlaid on the adhesive of the upper most layer of rice grasses or wheat stems of the leg, the panel comprising compressed rice grasses or wheat stems in a compact state and having a layer of adhesive over the lower most layer of rice grasses or wheat stems of the panel and having an upper layer of rice grasses or wheat stems being overlaid on the lower most layer of rice grasses or wheat stems.
A method of producing an environmental protective liner plank structure wherein several groups of rice grasses or wheat stems are first chopped into chips of rice grasses or wheat stems, then an adhesive is mixed with the chips of rice grasses or wheat stems and stirred into a thin state, then a certain amount of mixture is poured into the cavities of a female mold, the projecting legs of a male mold being used to compress the mixture in the cavities of the female mold, and such procedure is repeated to form legs of the liner plank, then, a certain amount of mixture is poured onto the upper surface of the legs and a plane board mold is used to downward press the mixture, such procedure being repeated until a panel of a certain thickness is formed, the adhesive being then evenly sprayed over the upper surface of the panel and then the female mold being taken off so as to achieve an environment protective liner plank made of chips of rice grasses or wheat stems and having legs and a panel.
