JPS5940972B2 - Slope greening method - Google Patents

Description

[Detailed description of the invention] The present invention relates to a slope greening method.

For example, if a road is built by carving out a mountain or building an embankment,
Slopes on both sides of the road, so-called slopes, are at risk of soil outflow and collapse.

For this reason, slope stabilization methods that prevent earth and sand from collapsing have been widely adopted.

The above construction methods include masonry construction, block construction, concrete frame construction, and concrete or mortar spraying construction methods.

However, in both construction methods, the foundation is hard, so
It is difficult to grow green plants, and the mountainous areas turn gray, destroying nature and causing problems in terms of landscape.

In place of this construction method, soil spraying is being adopted in recent years as it is effective in preventing slope collapse and revegetating the bedrock.

However, since the conventional soil spraying construction method creates a greening base directly on the slope, it has weak adhesion and is prone to collapse due to weathering, runoff, slipping, etc.

In addition, since the seeds are mixed with the soil and sprayed over soil,
Another drawback is that maintenance is difficult, as it takes time and effort to re-establish the seeds in cases of poor germination, fertilizer wilt, etc.

The present invention solves the above-mentioned drawbacks and provides a slope greening method in which the created greening base has strong adhesion and is easy to maintain.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 2, a wire mesh 2 as shown in FIG. 1 is placed on a slope 1 such as a sloped bedrock, and a plurality of coil meshes 3 are provided in parallel in the vertical direction on the surface of the wire mesh 20.
and form a mesh base 4.

In this case, the wire mesh 2 is fixed with anchors 5 driven into the slope 1,
Further, the coil net 3 is fixed to the slope 1 with anchors or tied to the wire net 2 with wire.

After completing the formation work of the netting base 4 as described above, greening soil is sprayed almost evenly onto its surface to create a stepped greening base 6 in which the upper part of the coil netting 3 bulges out, and the top of this base 6 is Shiba,
Spray seeds of grass, wildflowers, etc.

The greening soil has soil as a main component, and contains a curing agent and a greening base material.

Cement and fill tanks (adhesives such as glue) are used as curing agents, and pack linter (pulp waste), park compost (cow dung, rotting wood), and chemical fertilizers are used as greening base materials.

An example of the formulation is shown in Table 1.

In addition, when spraying, for example, grass seeds onto the surface of the greening base 60, it is preferable to position the seeds at a depth of about 2 crrL from the surface of the base 60.

At a depth of less than 2crrL, it is easily washed away by wind and rain.
Furthermore, at a depth of 2 Crn or more, the germination rate decreases.

As described above, according to the present invention, since the mesh base is interposed between the slope and the greening base built on it, the base has strong adhesion and reliably prevents collapse due to runoff, sliding, etc. It is possible to obtain a stable greening base.

In addition, since coil nets extending laterally are attached vertically in parallel to the surface of the wire netting, contour steps are formed on the surface of the greening base, which is uniformly sprayed with soil, to prevent seeds from flowing out. Effective and retaining seeds that have arrived,
It has good fixation and is convenient for greening.

In particular, since seeds are sprayed after the greening infrastructure has been created, if there is a problem with the seeds being washed away, poorly rooted, or withering the fertilizer, we will
Since it is only necessary to re-spray the seeds, it is possible to achieve many benefits such as easy maintenance.
