Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for treating organic waste generated at construction sites such as road construction and residential land development,
The present invention relates to a slope greening method and a net structure for knitting fences used in these methods.

[0002]

2. Description of the Related Art When greening slopes such as naturally collapsed mountain skins, thin mountain skins, and other mountain surfaces scraped off for road construction or residential land development, spraying a thick base material containing herbaceous seeds is generally performed. Vegetation works are performed on the slopes.

[0003] In addition, in order to achieve harmony with the surrounding landscape of the slope, early permanent stabilization, and restoration to the natural world,
Vegetation work by spraying a thick base material containing wood seeds and planting work by transplanting wood seedlings have been implemented on the slopes, so that the slopes can be greened by so-called forestation. I have.

[0004]

In the forestation of the slopes, the tree seedlings germinated and grown from the seeds and the transplanted tree seedlings grow slowly in the initial stage. Growing weeds and herbaceous plants, especially fast-growing pastures, are susceptible to pressure and it has been difficult to grow tree seedlings reliably and soundly.

On the other hand, it is not an exaggeration to say that waste generated by construction such as road construction and residential land construction is basically treated at the site, and that taking out of the site is prohibited. In particular, the current situation is that it is difficult to treat cut trees and their root stocks generated in large quantities on site.

[0006] At this point, attempts have been made to finely chip the felled trees and root stocks, which are organic wastes, and to reuse the shredded materials as greening materials for slopes. Even if the cut material is scattered in a layered manner on the entire surface of the slope, the thickness of the cut material is limited in consideration of the migration and the like, so that the amount of use is limited to a small amount.

[0007] In addition, the nitrogen content is consumed from the surrounding soil until the shredded material corrodes over the years, resulting in a so-called nitrogen starvation phenomenon. There was a problem in that even the growth of the plant was inhibited.

The present invention has been made in view of the above circumstances, and has as its object to remove organic waste generated at a construction site such as a road construction or a residential land development by using a slope at the construction site. Another object of the present invention is to provide a processing method capable of performing a large amount of return processing.

[0009] From another viewpoint, organic waste generated on the slope at the site to be revegetated can be treated effectively and in large quantities in the site, and in addition, especially when the slope is made into a forest, the woody seedlings are used. It is an object of the present invention to provide a slope revegetation method that is hardly subjected to pressure and can be favorably grown.

Another object of the present invention is to provide a net structure for knitting fences which is very suitable for use in a method for mass processing of organic waste or a method of greening a slope after treating a large amount of organic waste. I have.

[0011]

According to the first aspect of the present invention,
An organic waste treatment method that shreds organic waste generated at construction sites such as road construction and residential land development and returns the shredded products to the slopes at the construction site. A fence is erected in the contour direction at an appropriate interval in the direction, and a triangular recessed space is formed by the fence and the slope on the slope side of this fence. It is characterized by containing shredded products.

According to the above construction method, as the number of knitting fences is increased and the height of the knitting fences is increased, a large number of large triangular recessed spaces are formed in steps on the slope. Therefore, by storing shredded organic waste in this triangular concave space, a large amount of shredded material can be stabilized compared to scattered shredded material in layers on the slope. Thus, it can be held on the slope of the construction site.

[0013] The shredded material accommodated in the triangular recessed space functions to reduce the impact of raindrops caused by rainfall and to prevent migration of runoff on the slope surface soil. Is also effectively prevented.

The object of the present invention is to achieve both the large-scale treatment of organic waste generated on the slope at the site to be greened and the greening of the slope. Fences are erected in the contour direction at intervals, and a triangular recessed space is created by the fences and the slopes on the slope side of the fences. After shredding, the shredded material is housed in a triangular recessed space in a state where a space for greening is formed between the recessed space and the fence immediately above it, and in the space for greening. The feature is that vegetation works are performed.

According to the above-mentioned method, the shredded organic waste can be stably and massively retained on the slope at the site to be greened, and the shredded material effectively erodes the slope. Is as described above.

[0016] In addition to this, the storage area of the shredded material is specified to limit the generation area of the nitrogen starvation phenomenon due to the organic waste, and then the vegetation is constructed in the space for greening. Therefore, plants introduced for revegetation grow well without being damaged by the nitrogen starvation phenomenon.

Furthermore, since the shredded material reduces slope downflow sewage and improves the water retention of the entire slope, the shredded material eventually corrodes and assimilate with the soil, Since this becomes nutrients, healthy growth of the plant is promoted, and the slope can be reliably greened.

In particular, when vegetation for introducing trees is constructed in the above-mentioned greening space, the shredded material becomes a mulching material for preventing pressure from being applied. As a result, the tree seedlings are less likely to be subjected to pressure, and as a result, healthy and reliable growth of the tree seedlings can be expected. In this case, efficient disposal of troublesome organic waste and greening of slopes can be effectively achieved.

As a fence structure used in the above-mentioned organic waste treatment method and slope revegetation method, for example, a thinning material or the like is used as a knitting fence post, and at appropriate intervals in the length direction and the contour direction. Standing on a slope, of which, in the direction of the contour line, the fences of shredded material are constructed by arranging, for example, felling trees, or laying a net-like body, etc. can do.

However, this means requires a great deal of manpower and time for the knitting fence. Therefore, a net structure for a knitting fence having the following structure, that is, a plurality of cords laid in the lengthwise direction. To prevent one side of the net for the knitting fence from being connected to the body, and to prevent the net for the knitting fence from standing down on the slope by using the knitting fence posts while connecting the net for knitting fences to the body. It is advisable to use a net structure formed by connecting the second string-shaped member over the other end of the net in the width direction and the string-shaped member for a knitting fence (claim 3).

Preferably, the knitting fence posts are integrally provided on the net for the knitting fence at appropriate intervals in the contour line direction (claim 4). For example, even if a net has several knitting fence nets, it can be compacted by stacking the nets on top of each other and winding them up. Not only that, because it is lightweight, it has the advantage of being easy to carry and handle artificially.

When the knitting fence is used, for example, the net structure is brought above the slope and the plurality of cords are directed in the contour direction in the contour line direction. From below, expand the net for knitting fences by using the pillars, and fix the string-like body on the slope with anchors or the like as appropriate. When the net structure is provided with a plurality of nets for knitting fences, the net fence is formed on a slope like a hanging shelf on the slope in a state where the second string-shaped body prevents falling. Will appear.

It should be noted that, without integrating the knitting fence post into the knitting fence net, the strut and the net may be separately prepared, and the two may be integrated using, for example, a stapler. Alternatively, a pillar may be erected on the slope before integration, and a net may be fixed to this pillar using, for example, a stippler. In addition, the net is provided with a bag-knitted portion for inserting a pillar. Then, a column may be inserted into the bag knitting portion, and the column may be erected on the slope.

In any case, the net for the knitting fence is bent at one end in the width direction so as to conform to the unevenness of the slope, and constitutes a fence on the slope. By storing shredded organic waste in a triangular recessed space between the surface and vegetation in the space for greening, a large amount of organic waste can be treated at the same time The greening work is completed.

[0025]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a net structure 1 for knitting fences according to the present invention. This net structure 1 is used for a method of treating organic waste and a method of greening, and is laid in a plurality of lengthwise directions. One end in the width direction of a rectangular flexible knitting fence net 3 that is long in the contour direction is connected to the string-like body 2, and the knitting fence net 3 is connected to the knitting fence support 4.
In the state where the net 3 is erected on the slope by using the second string 5 for preventing the net 3 from falling, the other end of the net 3 in the width direction of the net 3 and the string 2 Are connected.

Specifically, the knitting fence net 3 in the length direction
Although the number of the deployed nets, the size of the net 3, the number of the cords 2, the laying pitch, the length, etc. are not specified at all, the unit length of the net structure 1 per unit is assumed to be 10 m. The following is an explanation of the integrated production of the net structure 1 assuming that is disposed on the slope N. First,
Assuming that five cords 2 each having a length of 10 m in the normal length direction are laid at a pitch of 50 to 60 cm in the contour direction, the length is adjusted to 200 to 240 cm according to this pitch.
And a net 3 for a knitting fence with a width of 50 to 70 cm.
0-7 sheets are prepared.

Although it is not necessary to make them coincide with each other, the length of the knitting fence net 3 is set to 5 mm between the both ends in the longitudinal direction of the knitting fence net 3 by using, for example, a stippler so as to match the laying pitch of the cord-like body 2. The knitting fence support 4 is fixed, and the net portion on one end side of the knitting fence support 4 or in the vicinity thereof is connected to the above 5
It is connected to the string 2 of the book at a pitch (100 to 140 cm) twice the width of the net 3, for example.

On the other hand, separately from the above-mentioned string-like body 2, five second string-like bodies 5 are prepared for each net 3, and the second string-like body 5 The central portion of the cord 2 between the nets 3 and 3 is connected to the other end of the knitting fence support 4 or the net portion near the other end, and a third portion is provided as necessary.
Is prepared and connected to the connecting portions of the cords 2 and 5 in the contour direction.

The net structure 1 is integrally manufactured as described above. For example, when greening a slope, a plurality of knitting fence nets 3 are overlapped with each other, and the nets 3 are wound up to form the net structure 1. The net structure 1 is conveyed to a site where greening of the slope is carried out, and the net structure 1 is appropriately lifted to the greening target area of the slope, for example, by hand, to prepare for greening of the slope. It is.

On the other hand, at the site to be greened, organic waste such as cut trees and root stocks generated at the site is crushed using a crusher or the like, for example, with a length of 1 to 20 cm and a thickness of 1 to 3 cm.
The shreds are cut into chips of about m, and the shreds a are stocked at appropriate locations in the greening target area.

Then, as shown in FIG. 2, the net structure 1 lifted to the area to be greened is specified by using the anchor 7a of about 30 cm in a state in which the laying pitch of the string 2 is specified. Fix the upper end side of the cord-like body 2 to the slope N,
The net structure 1 is unfolded toward the lower side of the slope N, for example, a connecting portion of three cords 2, 5, 6 or a connecting portion of the knitting fence net 3 and the cord 2. Is also 30cm
The net 3 for knitting fences is switched to the standing posture by fixing to the slope N by using the anchor 7b of the degree.

At this time, since the second string-shaped body 5 is connected to the knitting fence net 3, the net 3 for knitting fence is prevented from falling down below the slope. The knitting fence net 3 holds its standing posture by itself, and the knitting fence net 3 is flexible, so that one end in the width direction is well adapted to the unevenness of the slope N. And, on the slope N, 10 to 7 knitting fence nets 3
10 to 7 fences A appear as hanging shelves.

Here, when a plurality of the net structures 1 are installed so that the knitting fence nets 3 thereof are connected to each other in the contour direction, the adjacent knitting fence nets 3 are used, for example, by using a stippler. However, from the viewpoint of workability, it is desired to form a work passage between the adjacent nets 3 and 3 for knitting fences.

For this reason, although not shown, the net structure 1 is installed so as to form a work passage of, for example, about 50 cm between the adjacent nets 3 and 3 for the knitting fence, while the work passage is formed. A net for closing is prepared separately, and this net is connected to each other using a stapler in a state where a part of the net is superimposed on the nets 3 and 3 for knitting fences in anticipation of an appropriate work process. It is preferred to take.

In this manner, the hanging shelf-shaped fence A by the knitting fence net 3 is made to appear on the slope N, so that the fence A and the slope N To form a triangular recessed space Q, and a space for greening (in this embodiment, a knitted fence) between the recessed space Q and the fence A immediately above it. The width of the net 3 for 50-70c
m, the knitting fence net 3 is connected to the string 2 at a pitch twice as large as the width in the normal length direction, so that the space width is about 50 to 70 cm,
It may be set to about 100 cm. ) In the state where S is formed, the above-mentioned stock shredded material a is housed in the triangular recessed space Q, and vegetation for greening is constructed in the vegetation space S, so that the organic waste can be reduced. This completes the greening of the slope at the same time as mass processing.

It should be noted that the net structure 1 is not limited to being installed so that the nets 3 for knitting fences thereof are connected to each other in the contour line direction. The arrangement position of the net structure 1 and thus the net 3 for knitting fences may be made different in the normal length direction so as to assume the shape.

In this embodiment, as shown in FIG. 3, as a vegetation plant for greening, a pulp-based inner bag 8a is filled with a wood seed b1, a fertilizer, a water retention agent, and a soil conditioner. The vegetation mat 8 is placed in a space S for greening using a vegetation mat 8 which is sewn by accommodating a plurality of the vegetation in an outer bag 8b made of polyethylene, and a construction form of a mat construction for nailing is adopted. However, as shown in FIG. 4, before constructing the net structure 1 on the slope N, if necessary, a net-like body 9 such as a synthetic resin net, a metal lath wire net, or a net is formed on the slope 2. It is also possible to adopt a form in which the thick base material 8A containing the woody seed b1 is sprayed so as to cover the reticulated body 9 so as to be stretched upward.

Further, as shown in FIG. 5, while forming a concave portion Na for planting seedlings on the slope N, a pot seedling of a tree cultivated and cultivated in another place is prepared, and the woody seedling b2 is placed in the pot. c, and plant this tree seedling b2 in the concave portion Na, or if the pot c is a corrosive material,
It is also possible to adopt a vegetation construction in which the whole tree seedling b2 is planted with a concave portion Na, and a herbaceous seed may be selected instead of the above woody seed b1.

As the woody seed b1 or the woody seedling b2, kunugi, sharinbai, arakashi, rat mochi, zelkova,
Pinus densiflora, Japanese black pine, rowan, and the like are arbitrarily selected, and as the herbaceous seeds, short grass pasture seeds, flower seeds, and the like are appropriately selected, including rice vegetation.

As for grass seeds, white clover,
Creeping red fescue, red top, bermudagrass, Kentucky bluegrass, etc. are suitably selected, but the woody seed b1 or the woody seedling b2 is under pressure by the herbaceous plants, so the vegetation in combination with the herbaceous seeds Engineering shall be avoided.

According to the above construction method, the larger the number of knitting fences A and the higher the height of knitting fences A, the greater the number of large triangular shapes on the slope N in the contour direction. The recessed space Q is formed in a step shape.

Accordingly, it is possible to return the troublesome shredded material a generated at the greening target site to the slope N at the greening target site in large quantities and stably. Also, shredded material a
However, since the impact of raindrops is alleviated and the slope of the topsoil is prevented from moving, the erosion of the slope N is effectively prevented, and the water retention is also improved.

Since the storage area of the shredded material a causing the nitrogen starvation phenomenon is specified and the vegetation for greening is constructed in the space S excluding this area, the water retention is also improved as described above. Because of the improvement, the plant for greening will grow well.

Particularly, when vegetation for introducing trees is constructed in the above-mentioned space S, since the shredded material a becomes a mulching material for preventing pressure, the xylem germinated and grown from the xylem seed b1 The seedlings and the transplanted woody seedlings b2 are less likely to be subjected to pressure and grow reliably and soundly. In addition, the shredded material a eventually corrodes and assimilates with the soil, which is nourished. As a result, healthy growth of plants is promoted.

In this way, after about 5 years, for example, the tree seedlings b2 turn into trees, and the woody communities cover the stepped fence A. When viewed from directly below or when viewed from a distance, the appearance is good, and the greening of the slope N by the introduction of trees is effectively achieved at the same time as the large-scale treatment of the troublesome organic waste.

In the case where only organic waste generated at a construction site such as road construction or residential land development is to be treated, the vegetation work for the greening space S is omitted. The surrounding native seeds fly into the space S and germinate and grow there, whereby the slope N is naturally greened in a belt shape by herbs.

Alternatively, if it is not necessary to achieve greening,
As the height of the fence A is further increased and / or the growth pitch of the fence A in the lengthwise direction is reduced, so that the space S is eliminated, a larger amount of the shredded material a is formed into a triangular shape. It may be accommodated in the recessed space Q.

In the net structure 1 according to the above configuration,
The fence A formed by the net 3 for the knitting fence has a standing posture perpendicular to the slope N, and the angle of the standing posture of the fence A with respect to the slope N is determined by setting the length of the second cord-like body 5. Can be changed arbitrarily.

That is, although the length differs depending on the inclination angle of the slope N, when the length of the second cord-like body 5 is shortened, FIG.
As shown in (1), it is possible to obtain the net structure 1 in which the fence A by the net 3 for the knitting fence is set to a vertical standing posture.

According to the net structure 1 of this configuration, since the fence A does not exist vertically above the space S for greening, when the tree seedling b2 is introduced for greening the slope N, the tree seedling b b2
Grows straight without being hindered by fence A.

The material of the cord 2 and the net 3 for knitting fences may be made of synthetic resin such as degradable polyethylene or polypropylene which is corroded and homogenized with soil from an ecological point of view. It is desirable, but not limited to this. For example, the net 3 for a knitting fence can be implemented by replacing it with a metal lath wire mesh, punching metal, a non-corrosive hard or soft synthetic resin net, or the like. is there.

FIG. 7 shows a net structure 1 according to another embodiment. Net structure 1 according to this embodiment
Has a structure suitable for spraying the thick layer base material 8A with reference to FIG. 4, for example.

More specifically, a rectangular shape-preserving member 10 serving also as a support 4 of the knitting fence is provided around the knitting fence net 3 and a central portion in the longitudinal direction, while being stretched on the slope N. For example, the nets on both sides and the center in the width direction are regarded as a plurality of strings 2 laid in the direction of the length of the nets 9 which are long in the normal length direction. , 5 and 6, one end of the net 3 for knitting fence in the width direction is connected, and a second string-shaped body 5 for preventing the net 3 from falling down is connected to the other end of the net 3 in the width direction of the net 3. And the string-shaped body 2 is connected.

The net structure 1 shown in FIGS. 1 and 7
Then, for the net structure 1 per unit,
The knitting fence net 3 is provided with seven knitting fence nets 3 to form 10 to 7 triangular recessed spaces Q when installed on the slope N. As a result, the number of triangular recessed spaces Q is not limited to this, and only one knitting fence net 3 is provided for the net structure 1 per unit, and the net structure 1 per unit is provided. Against
One triangular recessed space Q may be configured.

In the embodiments described above, the structure 1 of the knitting fence A employs a compact, lightweight, and net structure which is excellent in handling.
As shown in (1), this can be implemented as a structure 1 of a wooden fence A.

Specifically, for example, a thinning material or the like having a length of about 1 m is used as a knitting fence post 4, and the post 4 is spaced at a distance of, for example, 1 to 2 m in the contour line direction and 50 cm in length.
A triangular recess for accommodating the shredded material a is buried in the slope N with a depth of about a degree, and is arranged so as to stack, for example, a band sheath 11 made of a cut tree over the struts 4 and 4 in the contour direction. A fence A forming a fence A forming an entry space Q, a shredded material a is accommodated in the triangular recessed space Q, and a vegetation is constructed in a space S for greening above the slope A. May be taken.

Alternatively, as shown in FIG. 9, instead of the above-described cut tree, for example, a net-like body is used as a band sheath 11, and the band sheath 11 is used.
May be bridged over the columns 4 and 4 spaced apart in the contour line direction to form the storage fence A for the shredded material a.

It is to be noted that, without performing the vegetation work on the space S, it is possible to carry out a method of processing only the shredded material a of the organic waste, or alternatively, the strut 4 and the band sheath 11 may be used.
And / or fence A in the length direction
It is also possible to reduce the growth pitch of, and carry out a processing method for a larger amount of the shred product a.
