Site forming material and covering method using the site forming material

The present invention relates to a site forming material for inducing root growth of plants planted in a parking lot, a street, or a building, and more particularly to a site forming material which can ensure the strength of the site and have a space for growing the roots of the plant, so that the plant can grow sufficiently. .

In recent years, the requirements for greening cities have been continuously improved, and trees have been planted in various locations in the city, such as parks, pedestrian walkways, expositions, parking lots, and squares. The roots of the planted trees are formed underground, because the growth of the roots supports the function of the trees, so the roots grow in the underground beyond the imagination. If it hinders the growth of the roots of the trees, it will affect the growth of the plants.

Generally, grass for grass growth is provided in a golf course, a baseball field, a parking lot, or a yard of a building. Based on the requirements of the greening city, the construction of grassland in the parking lot has gradually increased. However, in the same position as the parking lot, the foundation under the grass, in order to support the frequent access to the vehicle, it is necessary to have a certain degree of hardness, so as not to sink the foundation; but if the foundation is too hard, it will not be conducive to the construction of the grass. Even if the roots of the short grass are to be grown, it is difficult to elongate the root portion in the hard part of the foundation. In addition, the area where the car enters and exits will harden the soil of the foundation, making the roots of the short grass more difficult to grow.

Japanese Laid-Open Patent Publication No. 2007-49926 discloses a base material for inducing roots of a tree and a method for constructing a foundation using the base material for induction, which is to fill a plurality of coarse-grained materials at a construction site and has a smaller particle diameter than the coarse-grained material. In many fine particles and a holding material, the fine particles are fixed to the void portion between the plurality of coarse particles through the holding material, and the root portion of the tree is induced to grow by the void portion.
