Environment-friendly block for earthwall

摘要

The present invention relates to an environment-friendly block for constructing a retaining wall. The environment-friendly block for constructing a retaining wall is configured to have upper and lower surfaces, front and rear surfaces, and left and right surfaces, wherein each of the upper and lower surfaces is formed into a horizontal plane, and each of the front and rear surfaces is formed into a vertical plane. The left and right surfaces have two vertical planes. One of the two vertical planes is perpendicular to the rear surface at a rear surface side. The other vertical plane makes an acute angle at a front surface side. The width of the front surface of the block is larger than the width of the rear surface. In one embodiment, the left and right surfaces are symmetrical to each other, or in the other embodiment, the left and right surfaces are not symmetrical to each other, wherein one side surface comprises one vertical plane perpendicular to the front and rear surfaces. The block is made of concrete containing cement, stone flour, sand, an admixture, a useful microbial diluted solution, and mixing water, so the block has a function of purifying soil and water.
