Abstract

PROBLEM TO BE SOLVED: To ensure inexpensive and high quality greening by spraying crushed pieces of bark of cedar and Japanese cypress, paper making foreign matter and the like to the seed of a vegetation plant, a fertilizer and the grass or the crushed chips of timber produced by cutting down at a jobsite on a slope by mixing high temperature heated particulate coal. SOLUTION: Because the crushed pieces 1e of the bark of mixing cedar and Japanese cypress have feather-like fiber structure, constant coupling force is displayed by intertangling. Then, because they have a cellular structure divided into a number of fine chambers containing air and moisture, a fixed gas phase and a liquid phase are constituted. Thus, bacteria are helped propagating, and the compost of the crushed chips 1a of grass and timber is promoted. Furthermore, the crushed pieces 1e of the bark, paper making foreign matter and the like are sprayed with a compressor by additionally mixing high temperature heated particulate coal. The outflow of soil dressing 1a is prevented during rainfall on a spraying slope to secure proper water holding and fertilizer holding, and the compost of the crushed chips 1d of grass and timber is promoted. Thereby the early greening of the slope is promoted to secure long maintenance.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope vegetation work at a cut-off point of a mountain road or a bank of a river.

[0002]

2. Description of the Related Art Conventionally, slopes have been hardened with concrete for work to prevent collapse of road cut-off points and revetment work for river embankments, but in recent years, from the viewpoint of aesthetics and protection of the environment and nature, slopes with flowering and tree vegetation have been used. The greening method has been adopted everywhere.

[0003] The spraying method is generally used for these works, which includes seeds of vegetation such as flowers, fertilizer,
It was a method in which crushed chips of trees and grasses generated by logging at the site were mixed into the soil, and sprayed with a compressor on the entire slope with a constant thickness.

[0004] However, in these conventional slope spraying methods, the seeds of the vegetation plants sprout and take root after spraying, and if there is a large amount of rainfall during the period until planting to a certain extent, the soil will run off and the planting will not be greened. Therefore, there was a drawback that the construction itself became large-scale, such as covering with a net for the purpose of preventing the runoff, and the cost was increased.

[0005] In addition, crushed chips of grasses and trees generated by logging at the site are mixed for the purpose of disposal at the site and long-term replenishment of fertilizer to vegetation plants. In the sense of prevention, since the soil is generally densely formed, moisture and oxygen are not sufficiently supplied to the bacteria for turning the crushed chips into putrefaction compost, so that the composting does not progress as a result, There were many cases where this was a problem.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned circumstances, and has as its object to solve these disadvantages and to provide an inexpensive and high-quality slope.

[0007]

According to the first aspect of the present invention, in order to solve these problems, as a spraying material for a slope, a seed of a vegetation such as a flower, a fertilizer, and a cutting at a site are generated. The basic feature is that crushed chips of cedar and cypress bark are mixed in addition to crushed chips of grass and trees.

In claim 2 of the present invention, in order to solve these problems, seeds of vegetation such as flowers, fertilizer, and crushed chips of grass and trees generated by on-site cutting are used as slope spraying materials. In addition, crushed pieces of cedar and cypress bark,
The basic feature is that granular coal produced by heating papermaking slag at a high temperature is mixed.

[0009]

According to the first aspect of the present invention, since the crushed pieces of bark of cedar and hinoki mixed with each other have a feather-like fibrous structure, they are entangled with each other and exhibit a certain bonding force. It works to prevent the runoff of soil. As a result, the right vegetation base is maintained on the slope, which contributes to long-term greening.

[0010] The crushed pieces are microscopically divided into a large number of small rooms containing air and moisture therein.
Due to its cell structure, a certain gas and liquid phase is formed in the sprayed soil, which helps the growth of bacteria and promotes the composting of crushed chips of grasses and trees generated by cutting down contaminated sites. Work. Therefore, long-term supply of fertilizer to the slope will contribute to long-term greening.

[0011] In addition, the bark of cedar and cypress has pest repellent properties, so that the growth of pests such as brown rice in the soil is suppressed, so that the roots of vegetation are not eaten and consequently long-term greening is achieved. Contribute to maintenance.

[0012] In claim 2 of the present invention, in addition to claim 1, since the mixed granular charcoal is porous, it takes in moisture and fertilizer into the inside thereof, and further improves water retention and fertilization. As a result, it contributes to long-term greening maintenance.

[0013] Furthermore, granular coal has a heat retaining property due to the carbon material, and contributes to long-term greening maintenance by mitigating a nighttime temperature drop in winter and protecting roots.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a cross-sectional view showing a general construction part of a slope spraying work, and FIG. 2 is a schematic view showing a configuration of a conventional slope greening method. FIG. 3 is a schematic diagram showing a configuration of a slope greening method according to claim 1, and FIG. 4 is a schematic diagram showing a configuration of a slope greening method according to claim 2.

[0015] As shown in Fig. 1, the slope spraying is generally performed on a sloped slope and a part of a top flat portion.
If necessary, it may be applied to the lower flat part. The thickness of the sprayed layer is generally about 3 to 10 cm, but depending on the case, it may be as thick as about 25 cm. In addition, the slope angle of the slope may vary from a gentle slope of about 20 degrees to a steep slope of about 75 degrees, and in some cases, is applied to a vertically steep cliff.

FIG. 2 shows an example of a conventional construction method. In this case, seeds 1b of vegetation such as flowers and trees are mixed in the soil 1a in an appropriate amount. An appropriate amount of fertilizer 1c such as phosphoric acid / potassium was mixed in, and an appropriate amount of crushed chips 1d of grasses and trees generated by cutting on site was also mixed in and sprayed with a compressor.

On the other hand, FIG. 3 shows an embodiment according to the first aspect of the present invention. In FIG. 2, crushed pieces of bark of cedar and hinoki are additionally mixed in with FIG. 2 and sprayed by a compressor. The crushed pieces of the bark of this cedar or cypress are usually needle-shaped fibers or crushed pieces in the state of feathers, and the thickness of the fibers is about 0.1 to 1 mm in diameter.
The length is about 5 to 30 mm. The mixing amount is usually in the range of 10 to 40% by volume with respect to the soil, and if it is less than this, it is not possible to sufficiently secure both the gas phase and the liquid phase. Is not enough.

On the other hand, FIG. 4 shows an embodiment according to claim 2 of the present invention. In FIG. 2, crushed pieces of bark of cedar or cypress and granular charcoal made by heating papermaking residue at a high temperature are additionally mixed. And it is sprayed with a compressor.

The crushed pieces of the bark of cedar or cypress are usually needle-like fibers or crushed pieces in the form of feathers. The fibers have a diameter of about 0.1 to 1 mm and a length of about 5 to 30 mm. Has adopted. The mixing amount is usually 10
To 40% by volume, and if it is less than this, it is not possible to sufficiently secure both the gas phase and the liquid phase, and if it is too large, the supply of fertilizer will not be sufficient.

The granular coal is usually substantially spherical, and its size is about 0.1 to 2 mm in diameter. Usually, the mixing amount of the granular coal is desirably in the range of 3 to 10% by volume with respect to the soil. If the amount is less than this, the water retention / fertilization and heat retaining effects of the granular coal cannot be expected much. The supply will be insufficient.

In the above description, the present invention has been described in detail with respect to a specific embodiment. However, the present invention is not limited to such an embodiment, and various other embodiments may be included within the scope of the present invention. The possibilities are clear to the skilled person. For example, in the present embodiment, an example is given in which crushed chips of grass and trees generated by logging at the site are mixed, but these crushed chips need not be mixed.

Another advantage of the present invention is that it does not require a net for preventing runoff. However, there is no problem if a net is used in combination with a vertical wall or a wall having a reverse slope. Fragments of the bark of the hinoki are entangled with the net, so there is an advantage that the effect of further preventing runoff can be improved.

[0023]

As described in detail above, if the slope greening method of the present invention is used, it is possible to prevent the runoff of the soil during rainfall on the sprayed slope, and to maintain appropriate water retention and fertilization on the slope. In addition, the composting of crushed chips from grass and trees cut down on the site, which has been mixed, can be promoted, and the temperature drop in the soil during the winter night can be mitigated.As a result, early greening of the slope can be promoted, and its long-term maintenance can be maintained. It becomes possible.
