Abstract

The forestation method is used for spraying special forestation material on an area through which water can not be passed, e.g. steep rock slope or concrete area. The forestation method comprises installing nets at regular intervals on the surface of the rock slope or concrete area, forming wells and water passageways on the surface of the rock slope or concrete area, spraying special forestation material which is mixture of soil improvement material, soil stabilizer, sawdust, and others, and spraying plant seeds.

Description

Surface greening method by spraying special vegetation material

1 is a first step of installing the well while arranging irregular existing rock.

2 is a second step of installing the net with anchor bolt on the inclined surface.

3 is a third step of forming a vegetation base by attaching a special vegetation material in a unitary structure.

4 is a state in which greening is achieved by spraying and seeding vegetation seeds of the fourth process after the foundation.

The present invention is a rocky area without any topsoil, or river masses, extreme crushed land (no fertilizers), coastal landfills, contaminated soil landfills, especially steep slopes. After installing a minimum of artifacts in the impervious layer area such as rock or horizontal concrete surface, it is fixed by sprinkling special vegetation materials (high pressure injection type) and sowing various vegetation plants to restore natural state as well as slope. It is related with the surface greening method by spraying special vegetation material which can protect the plant stably.

Currently, rock or instructor soil has no special method of natural recovery, so it has been left as a rockfall prevention facility or finished with non-vegetable retaining wall, block stacking, cement spraying, or even greenery. The amount of water needed for the feedstock was insufficient, especially during the dry season, resulting in grass death.

Therefore, the present invention provides a stable protection of the impervious layer area, that is, the slope of the rock or the upper surface of the rock, which cannot be vegetated by the existing seed dispersing method or any conventional method. It aims to provide a greening method that can protect human living environment by restoring nature by greening by plants.

An embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a first step to arrange irregular existing surface (1) of construction area under suitable conditions for construction, and to check and maintain channel, culvert drainage, side hole, etc. at the upper surface of the surface, and to adjust appropriate size (about 15cm × 10cm × 10cm It is preferable to install two or more well tanks (2) per square meter in a staircase type or a single type. The natural irregular curved surface is maintained to be suitable for the landscape, and the wells are formed.

The water permeable layer of the present invention as the main target is to install a well bucket to increase the water capacity necessary for the growth of the plant, and in addition to the advantage in the fixed land, the work.

2 is a second step of installing the net on the surface where the first step is completed, and is installed for the purpose of preventing the collapse of the partial surface due to weathering and fixing the vegetation material on the steep slope.

The net 3 installs an elastic ridged wire or nylon net as necessary. The wire mesh is installed when the slope is long and the slope is steep and there is a risk of falling rocks and partial collapse. The nylon mesh can be used when the slope is gentle and the slope is short.

This net installation is to be installed to have a gap between the surface and the fixing by using the anchor bolt (4) in the upper and lower, so as to maintain a standard tension.

3 is a third step of attaching the special vegetation material in a monolithic structure on the surface where the second step is completed.

Special vegetation material refers to vegetation soil (5) as the main material to ensure the survival and growth of plants. Colored soil is an artificial blending material that provides moisture, minerals, organic matter, etc. necessary for plant growth and provides space for maintaining roots. Soil improver, organic fertilizer, adhesiveness to special corrosive materials (leaf and similar materials) By mixing clay and curing agent and adding special foaming agent, it is to prepare special soil which has the best water retention and maintenance, and enables the formation of single grain structure. At this time, the blending ratio of each material is determined according to the soil soil, slope of the surface, spray thickness, climate, and fonto.

In particular, the porosity must be increased in the vegetation layer in order to increase the water repellency of the impermeable layer and to improve the rooting ability. The present invention is to add pitmos and boiled sawdust to the soil improving agent. Combined with the well's function of the water will solve the problem that was always a problem, and improve the water retention.

Here, the peat moss and the boiled sawdust added to the soil improving agent have a water retention capacity while increasing the porosity in the vegetation layer and minimize the evaporation of water, thereby improving the stability of the vegetation layer on the impermeable layer and the root proximity. You can do it.

Here, the curing agent is a vegetable fiber that connects each material to form a soil monolithic structure and is used for the purpose of bonding strength. The amount of the curing agent is also determined according to the mixing ratio of the special soil.

Foaming granules are used for the purpose of forming a monolithic structure that foams to have voids like a honeycomb type by maintaining the specially-formed monolithic structure in combination, and decides the addition amount according to the weather, weather and thickness of the rain.

The special adhesive stabilizer and chemical fertilizer are mixed with natural water and sprayed at high pressure to provide a vegetation foundation of suitable thickness on the surface as shown in FIG.

The application criteria of the material spraying thickness according to the conditions of the construction area are as follows.

As shown in the above chart, the thickness of vegetation material should be different according to each local condition. As the thickness becomes thicker, it is elastic to adapt to expansion and contraction by high temperature and freezing by installing net to reinforce ground stability and adhesion. You will have a vegetation layer.

After the vegetation layer is sufficiently stabilized, the fourth step of spraying the seeds by a conventional HIERO SEEDING method is performed, and the greening of the plant can be achieved as shown in FIG. 4 by maintaining the moisture and temperature necessary for germination. It can be.

The present invention, such as the formation of a large number of wells in the impermeable layer, such as a rock area or a concrete surface that does not have any capacity to increase the water capacity to increase the water is easy to supply the moisture required for grass growth, even in the dry season It is easy to supply and it is possible to grow plants of impervious layers. In addition, it is possible to improve the pore formation in the vegetation soil by adding and mixing peat moss and boiled sawdust with soil improver in the vegetation layer made of vegetative materials. This will improve the rooting of the grass roots.

Therefore, it is possible to plant greenery in cancers, river masses, coastal landfills, and contaminated soil areas, where plant growth has not been possible, thus restoring the damaged nature, preserving human living environment, beautiful scenery, and stabilizing the law permanently. It can be effectively used for local landscaping projects.
