The present invention relates to an eco-friendly revetment method that is configured to prevent disasters and plants to grow easily, and more particularly, to achieve structural greening and to achieve natural greening at the same time as well as its structural stability. It prevents the generation of harmful substances in the process, so that it is possible to implement a natural friendly revetment.

As is well known, the banks of rivers, banks, dams, reservoirs, or reservoirs, or the cuts of land or land created by various works, are left undamaged and lost due to sediment accumulated on the ground. do. In addition, it is exposed to the risk of ground collapse due to external forces such as rainfall and snowfall, which makes it difficult to carry out water and flooding functions and also damages the surrounding natural environment and landscape. .

In recent years, in order to solve the above problems, various shapes of revetment blocks are installed on slopes of rivers or banks, or various cutouts and fillets to prevent forced loss, thereby improving the effect of completion and dimensions. Protection law is in force.

However, if the construction of the revetment blocks facing each other on the surface of the various incisions and land, as each block is not integrated with each other, it becomes very vulnerable to supporting the overall stability due to inequality, partial dropout, etc. It is difficult to maintain the ecosystem because it is impossible to grow, the vegetation is not secured, there is a problem that impairs the environment and harms the surrounding landscape as a whole. In addition, the above-described pavement method has a lot of problems, such as a rainwater downfall on the ground is not a good reason for the rainwater to fall into the basement because it is a factor that causes an excessive increase in runoff during the rainy season.

Recently, the vegetation relief block method has been attempted to form a protruding shape or perforation block in order to construct an ecological block in an eco-friendly manner, and to form a vegetation hole in which plant roots can be implanted on the ground. When external loads such as snow are applied, the binding force between each bank block object is weak, causing lateral flow and unequal settlement. This causes the problem of deterioration of the aesthetics by collapsing the alignment state at the beginning of construction, and creates a puddle of water or provides a cause for the loss of earth and sand in the lake, leading to a problem of deterioration in stability.

In view of this, Patent No. 474661 discloses curing by installing concrete for one-time formers, and curing them by incineration of the one-time formers, filling the removed space with soil, and planting plants. In order to promote structural stability and improve the natural environment by planted plants, eco-friendly on-site rafting and packaging methods using RC and foamers have been disclosed.

However, since the method according to Patent No. 474661 has to be removed by incineration of the former after the curing of concrete is poured, a separate firearm or other equipment is required, so that the cost of equipment is increased and the process of removing the former is added, which increases the construction period. There are inevitably shortcomings, and incineration of these formers results in an inseparable pollutant that causes air pollution.

The present invention has been proposed in view of this point, and after installing the formwork with a lid to cure the concrete after lifting the lid of the formwork to remove, or to remove the formwork itself, the soil after filling the plant in place By planting the back, you can achieve natural greening along with the structural stability of the lake, as well as make the form removal process very simple, and to prevent the disaster that does not generate pollutants when removing the form, It is to provide an eco-friendly revetment method that is configured to grow.
