Abstract

PURPOSE:To reinforce sloped ground in a short period by a method in which a grass-planting mat having a water-passing mat on its bottom side, a perforated plate on its surface side, and a soil-receiving rib on the surface of the perforated plate is laid on a sloped ground, and soil is placed on the surface of the grass- planting mat. CONSTITUTION:A sloped ground 10 is leveled off, and a grass-planting mat 1 is laid on the surface of the sloped ground 10 by turning its water-passing mat 2 downwards and fixed by anchors 11. Soil 13 mixed with fertilizer and seeds 12 is sprayed onto the surface of the mat 1 and soil 13 is packed into the space between soil-receiving ribs 4. Since the water-passing mat 2 becomes layered on the bottom of the mat 1 to form a pathway for underground water, the run- off of the soil 13 can be prevented. Also, since the soil 13 and the seeds 12 are mixed and packed into the space between the soil-receiving ribs 4, the run-off of the seeds by rain water, etc., can be avoided, and greens-planting work having a necessary density as expected can be obtained.

ころである。Generally 1. Grass such as grass is planted on the slopes of mountains that have been cut down for roads and other construction work, as well as newly constructed embankments and residential areas, in order to prevent the surface soil from being washed away by rainwater. There is. When growing this type of grass, if the slope is sandy and gravelly, it is not possible to sow or plant seedlings directly, so additional soil is required. Conventionally, in order to fix this soil, a net made of synthetic resin is laid, and the soil is applied on top of the net and the seeds are sown.

The gist of this method is to level the sloping construction slope on which grasses are to be grown, and then use a synthetic resin material on the construction slope to allow water to flow freely in the thickness direction and in the plane direction. a perforated plate made of a flexible synthetic resin plate fixed to the surface of the water permeable mat, and a surface of the perforated plate opposite to the water permeable mat. A grass planting mat is provided with a large number of soil receiving ribs that protrude continuously in the width direction, and a large number of through holes that are opened along the back base of the soil receiving ribs of the perforated plate. Place the water mat with the water mat facing down and the soil receiving ribs at an angle, and fill the spaces between the soil receiving ribs with soil mixed with fertilizer and grass seeds. The method of grass vegetation on slopes is characterized by:

次に本発明の実施例を図面について説明する。Next, embodiments of the present invention will be described with reference to the drawings.

まず本発明方法に使用する草植マットの一例を第１図、
第２図について説明する。この草植マット１は全体が幅
約１ｍ程度の帯状に形成され、通水マット部２と穴あき
板３とが層状配置に一体に重ね合わされて構成されてい
る。First, Fig. 1 shows an example of a grass planting mat used in the method of the present invention.
FIG. 2 will be explained. This grass planting mat 1 is formed into a belt shape with a width of approximately 1 m as a whole, and is constructed by integrally overlapping a water-permeable mat portion 2 and a perforated plate 3 in a layered arrangement.

通水マット部２は合成樹脂材料により網状に一体成形し

A large number of through holes 5, 5... are formed at regular intervals along the base of the back surface of each soil receiving rib 4, 4... 4, 4, . . . are arranged at an angle with respect to the longitudinal center of the mat 1, as shown in FIG.

更に各土受リブ４，４・・・・・・の頂部にまたがらせ

のである。In this example, a net material layered on the water-permeable mat part is used, but other material such as a non-woven fabric with high porosity may be used to allow water to flow freely in the thickness direction and in the plane direction. Any material that can hold the soil and expand its value is sufficient, and a surface net is not necessarily required.

て高さが異なるように傾斜させる。Next, an example of the present invention using the above-mentioned grass planting mat 1 will be described. First, as shown in FIG. 3, a grass vegetation slope 10 such as an embankment or a slope after cutting down is leveled, and a grass mat 1 is laid on the surface with the water passage mat portion 2 facing down. When laying this, anchors 11 are driven in, and
Both ends are embedded in the slope 10 and firmly fixed. Also, at this time, the soil receiving ribs 4, 4, . . . are inclined so that the heights are different at both ends.

Fill it. At this time, the thickness of the top soil 13 is the surface net 6
The thickness and eggplant to be embedded.

このように施工された傾斜面においては草植マット１の
底面に通水マット部２が層状となって存在することとな
り、これが伏流水の流路となる。On the slope constructed in this way, the water-permeable mat portion 2 is present in a layered manner on the bottom surface of the grass planting mat 1, and this serves as a flow path for underground water.

また、客土１３は土受リブ４，４・・・・・・間に充填

Furthermore, the rainwater is received by the corner a between the soil receiving rib 4 and the lower part of the perforated hole of the perforated plate 3, and slowly flows along the slope of the soil receiving rib 4 (
It flows downhill. Further, roots generated from the seeds 12 extend into the soil through the through holes 5.5 of the perforated plate 3 and the water-permeable mat portion 2, thereby holding the vegetation mat 1.

本発明の傾斜面の草類植生方法は上述の如く構成され、

る。The method for growing grass on a slope according to the present invention is configured as described above,
When applying soil to the construction slope, a grass planting mat is laid that has a water-permeable mat portion on the bottom side, a perforated board on the surface side, and soil receiving ribs on the surface of the perforated board, By placing the top soil on the surface, the top soil will not be washed away by flowing underground water, and the top soil will be retained well.

また種子は客土と混合されて散布されるため客土による
保持が良好に行われかつ土受リブ間に客土とともに充填
されるため、雨水等による流失がなくなり、あらかじめ
想定した必要な密度の植生が得られる。In addition, since the seeds are mixed with top soil and dispersed, they are well retained by the top soil, and are filled between the soil receiving ribs with top soil, eliminating the risk of being washed away by rainwater, etc. Vegetation is obtained.

更に、土受リブが傾斜した配置に連続しているため、雨
水の保持が発芽、育成のために適正な状態となり、施工
