Description

  This invention relates to a soil-friendly greening shelf using thinned wood from a forest.

  In recent years, many eco-green fences have been provided for the purpose of planting seedlings on mountain slopes, such as mountain forests, for greening, and preventing sediment collapse. And the conventional eco green fence combines one end of a cross and a vertical tree, and combines a substantially L-shaped fence with a corner fixed with a metal stopper and a plurality of cross or plastic nets. What was constructed was often used.

  However, the disadvantage of the conventional Eco Green Fence is that it has a bad influence on the natural environment because it uses metal stoppers and plastic nets. There was an economic problem, such as causing sediment runoff and increasing material costs and construction costs.

  Therefore, in the future, there is a need for the development of an eco-friendly green fence that is friendly to the natural environment, can be easily constructed by anyone, has good aesthetics, and is economical. The greening shelf that was filed earlier (actual application 2007-002306) was devised. It was done.

  However, since the greening shelves invented and devised so far have the same size and shape regardless of the soil quality, there are some places where the quality is excessive depending on the construction site (soil), or the strength is insufficient. It was. Therefore, in order to solve such problems, it is desired to develop an optimal greening shelf according to the construction site and soil quality.

For reference, we will introduce the patent documents of eco-green fences (greening shelves) that have been filed so far. (See Patent Documents 1 and 2.)
