[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat-type green vegetation method and its vegetative vegetation method in which a flat or cylindrical green vegetation mat is spread over the ground (slope) that has been constructed or grounded to make it green. It is related to the mat.

[0002]

2. Description of the Related Art Conventionally, on a ground (slope) on which a reclaimed land, a bank, a collapsed slope, etc. has been leveled, the ground is sown with a seed soil containing seeds for greening. For example, a spray-type greening vegetation method is generally used in which the soil containing seeds for greening is directly sprayed onto the ground soil to form an appropriate soil layer for greening. In addition, on the ground (slope) where there is a risk of runoff or collapse due to rainwater, etc., or where there is little surface soil, boulders, crushed stones, etc. are laid on this ground or wire mesh is laid to protect it. The spray-type greening vegetation method is used to spray the incoming soil and form a thick soil layer for greening. In the case of this construction method, it has also been proposed to insert a water-soluble tubular body containing a soil containing greening seeds into a wire net at appropriate intervals, if necessary. In addition, a grid-like degradable frame with a soluble lower sheet is laid on the ground, and the soluble upper sheet is covered with the soil containing compost, plant fibers, and seeds. A formwork-type greening vegetation method for establishing and greening has also been developed and proposed.

There is.

Further, in the formwork-type green vegetation construction method as described above, a decomposable frame body having a soluble lower surface sheet is arranged on the ground,
This is a construction process in which the soluble soil is packed into the degradable frame and the soluble top sheet is stretched, which requires a lot of labor and time, and there is a limit to the stable function of the soil due to the mixed plant fibers, and there are variations in greening. And the soluble sheets on the upper and lower surfaces melt, the soil sediments with the plant fibers in a relatively large amount on the lower side of the frame, and the frame is exposed over a long period of time, which causes problems such as use on slopes. is there.

The present invention was developed in order to solve the above-mentioned problems. The object of the present invention is to attach a natural fiber to a bag formed of a degradable sheet and a net made of a natural fiber. To provide a mat type green vegetation construction method and its green vegetation mat with improved operability, greening performance and reliability by laying a vegetation vegetation mat containing a floor fiber layer and a soil containing seeds for vegetation on the ground. is there.
