[Patent Document 1]
JP, 2001-207453, A In recent years, recycling and zero emission have permeated, and improvement of processing methods for unused biomass such as locally generated materials and industrial waste continues to be desired. For this reason, factory production methods are used in which locally generated materials are processed into chips or wood wool and sent to the factory for incorporation into products. However, locally generated materials incorporated into products are mechanically and economically used as raw materials. Due to many restrictions, it was difficult to use a large amount of locally generated materials.
[0003]
The present invention has been made in consideration of the above-mentioned matters. The purpose of the present invention is to provide a greening auxiliary material that can easily accommodate and effectively use a large amount of waste such as locally generated materials, and greening using the same. It is to provide a construction method.
[0004]
[Problems to be solved by the invention]
In order to achieve the above-mentioned object, the present invention communicates a plurality of nets in the longitudinal direction continuously or at an appropriate interval between the nets of a double-structured net body with a front net and a back net superimposed. In the cross section between the front net and the back net, the storage section is provided along the horizontal direction, and a cylindrical waste material having a diameter less than one half of the longitudinal length of the storage section is inserted into the storage section. greening auxiliary materials which had been continuously triangular gaps substantially longitudinally stretched on the slope, than the slope gradient by blowing vegetation substrate in part batchwise according to the thickness of the greening auxiliary materials Zhang after casting A greening method (Claim 1) characterized by forming a gentle slope is provided.
[0005]
According to this configuration, the cylindrical stem material, such as reeds and branches of plants such as reeds, log-like timber such as thinned wood and locally generated wood, fertilizer, soil improver, Effective use of a large amount of waste material as a stopper by appropriately selecting one or more of water retention materials, vegetation base materials, chips, waste materials, etc. packed in a long cylindrical bag I can do it.
[0006]
At this time, the diameter of the cylindrical waste material is set to one-half or less of the longitudinal length of the housing portion, preferably 1/10 or less of the longitudinal length of the housing portion, so that the upper and lower sides forming the housing portion Since the net is spread by the cylindrical waste material and a gap is formed between the front net and the back net, the greening auxiliary material can be three-dimensionalized.
[0007]
The greening auxiliary material used in the above-mentioned greening method is a plurality of continuous communication in the vertical direction between the two nets of the double-structured net body in which the front net and the back net are overlapped or at appropriate intervals. A transverse section is provided between the front net and the back net by inserting a cylindrical waste material having a diameter less than one half of the longitudinal length of the accommodation portion into the accommodation portion. The substantially triangular voids are continuous in the vertical direction (claim 2).
[0008]
According to this tree planting method, the cylindrical waste material serves as a stopper, and the vegetation base surface is prevented from flowing out by the net, so that the vegetation base can be reliably held.
[0009]
Furthermore, since the surface formed by the greening auxiliary material stretched on the slope has a surface that is gentler than the slope gradient, the vegetation base material blown into the gap is dried with a substantially reduced inclination angle. It becomes less susceptible to obstacles, and vegetation can be applied more effectively.
[0010]
As the vegetation base material to be blown in, existing greening base materials mixed with seeds and fertilizers and wood chips can be used, but they are included in the surface soil by blowing in the forest surface soil around the construction site. The greening in harmony with the surrounding vegetation by the buried seeds is expected and preferable.
[0011]
In addition, in the part where the vegetation base material is not blown, the growth surface is naturally formed by depositing the slope surface soil to be washed away on the cylindrical waste material, and the seeds flying from the surroundings are netted and cylindrical. The greening in harmony with the surrounding environment is restored because it is captured by waste materials.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a slope on which the greening auxiliary material of the present invention is stretched.
The greening auxiliary material 1 is formed with a storage part 4 that is continuous in the vertical direction and communicated in the horizontal direction with the upper and lower double nets 2 and 3, and a cylindrical waste material 5 is inserted into the storage part 4. . This greening auxiliary material 1 is fixed to the slope S by an anchor 6.
[0013]
Said cylindrical waste material 5 processed the bundle of reeds, and the diameter is set so that it may become 1/3 of the length of a storage part lengthwise direction. By inserting this cylindrical waste material 5, the upper and lower nets 2, 3 forming the accommodating portion 4 are expanded by the cylindrical waste material 5, and a gap is formed between the front net 2 and the back net 3. As a result, a three-dimensional space is formed, that is, substantially triangular voids are continuous in the vertical direction in the cross section.
[0014]
Then, as shown in FIG. 2, when the vegetation base material 7 is blown into the gap by using a spraying machine (not shown) so as to match the thickness of the greening auxiliary material 1, the vegetation base material 7 has a cylindrical shape. Since the front net 2 is positioned on the surface of the vegetation base material 7 while being held by the waste material 5, it is reliably held on the slope S and greening is achieved. Further, since the slope formed by the front net 2 becomes gentler than the slope S slope, the substantial slope of the vegetation base material 7 becomes gentle, and the greening base becomes more stable and dry. Obstacles can be reduced.
[0015]
In addition, the cylindrical waste material 5 is not limited to this, but is obtained by processing stems and branches of other plants into a bundle, log-like wood such as thinned wood and locally generated materials, One or more of fertilizers, soil improvement materials, water retention materials, vegetation base materials, chips, waste materials, etc. packed in a long cylindrical bag can be selected as appropriate.
[0016]
As the base fabric of the bag body to be used, a nonwoven fabric or a net-like body can be selected as appropriate, but those made of corrosive fibers such as plant or biodegradable plastics are preferable from the environmental viewpoint.
[0017]
Waste materials that have little impact on plant growth and do not contain harmful substances can be applied. Steelmaking slag, oyster shells, thinning / thinning materials, root removal, on-site generated soil, food residues (fruit peels, etc.) ) Can be suitably used.
[0018]
The net that constitutes the greening auxiliary material 1 can be made of plant fiber, chemical fiber, metal, etc., but it is preferable to use a material that completely decomposes after several years in terms of reducing environmental impact. . As the material, palm, jute, or biodegradable plastic fiber can be used. In addition, the net mesh should be wide enough to allow the vegetation base to be blown in, and it should have a scale (for example, about 1 inch) that can prevent the vegetation base from being washed away. It is preferable that a dense portion is provided at a place that supports the waste material because the base material can be prevented from running away.
[0019]
As the vegetation base material 7, existing greening base materials mixed with seeds and fertilizers, wood chips, etc. can be used, but they are included in the surface soil by blowing in the forest surface soil around the construction site. The greening in harmony with the surrounding vegetation by the buried seed 8 is expected and preferable.
[0020]
The vegetation base material 7 may be blown over all the slopes, but it is also possible to blow partly (such as stripes or a houndstooth pattern) and intentionally avoid artificial vegetation.
[0021]
According to this configuration, in a place where the vegetation base material 7 is not blown, that is, in a portion where greenery is waiting for natural vegetation, the growth base is formed by depositing the slope surface soil to be washed away on the cylindrical waste material. While forming naturally, the seeds flying from the periphery are captured by the net and cylindrical waste material. And the natural vegetation can be restored | restored because the flying seed 9 germinates and grows.
[0022]
In the greening auxiliary material 1 used for standby greening, it is preferable to provide thin cotton, wood wool, or the like at a portion in contact with the slope S because the flying seeds 9 are more easily captured. Furthermore, by selecting a cylindrical waste material 5 in which the surrounding forest surface soil is packed in a long cylindrical bag, both buried seeds 8 and flying seeds 9 can be used, and natural vegetation can be used. It is desirable that the time required for restoring can be shortened.
[0023]
【The invention's effect】
As described above, in the greening auxiliary material of the present invention, as a cylindrical waste material, the stems and branches of plants such as reeds are processed into bundles, log-like wood such as thinned wood and locally generated wood, By appropriately selecting one or more of fertilizers, soil improvement materials, water retention materials, vegetation base materials, chips, construction waste materials, shells, etc., packed in a long cylindrical bag, etc., a large amount of waste Material materials can be used effectively as a stopper.
