DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a greenery foundation for a slope such as a cut slope of a mountain.

[0002]

2. Description of the Related Art Conventionally, greening of a slope has been performed by installing a wire mesh on the slope and then spraying a base soil containing seeds, fertilizer and adhesive from above. However, the base soil layer deposited by spraying is 3 to 1 due to the slope.
Plants tend to wither in the dry season with a small thickness of 0 cm and less rain. Especially when the slope is rocky or concrete sprayed, the plant often dies in a few years due to drastic drying. In addition, there is a problem that even if the slope is steep, even if the slope is steep, the base soil cannot be retained and the soil cannot be maintained due to falling. Therefore, the applicant of the present invention disclosed a method of locking a water-permeable bag body on an inclined surface in Japanese Utility Model Application Laid-Open No. 5-7312 and pressing a base soil into the bag body. Therefore, on a steep slope, the load from above is applied to the lower side and the weight becomes heavy, and it takes time and effort to hold the bag, and the upper surface is closed, which hinders good growth.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a greening base construction capable of easily retaining soil of a base soil and a large amount of soil, forming a wide base surface area on a gentle slope, and performing various types of greening. It provides the law.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a greening foundation for a slope such as a slope, and a fence holder for supporting a retaining fence such as a net fence is fixed to the slope. At the same time, hold the soil fence body upright and hold the bottom part of the soil fence body in the ascending direction of the slope, place the soil retention sheet from the lower part of the soil fence body to the bottom part folded part, and then put the fertilizer base In this method, the soil is put on the back side of the retaining fence body, and the greening foundation is constructed on a slope with a gentle slope of the base soil. Then, the fence holder is fixed to the inclined surface at predetermined intervals in the horizontal direction, and the retaining fence is held by the plurality of fence holders .
This is a method of constructing a greenery foundation on an inclined surface with rows of upper and lower rows . In addition, the retaining fence body may be a net fence such as a wire mesh, the lower end folded portion of the net fence may be in contact with the ascending direction of the inclined surface, and the retaining sheet may be arranged from the upper rear surface of the raised net fence to the lower end folded portion. . Further, the soil retaining sheet may be formed of a water-permeable sheet. Further, the lower end folded portion of the net fence may be shorter than the folded ground portion at the lower end of the fence holder.

[0005] Since the retaining fence body is erected from a substantially vertical position to a forward inclined state, a large amount of base soil can be held between the earth fence and the inclined surface. It can be prevented from falling from. In addition, by forming a folded part at the lower end of the retaining fence body and arranging the retaining sheet from the lower part of the retaining fence body to the lower end folded part, the base soil falls from the gap generated between the uneven slope surface and the retaining fence body. It does not work, and it becomes stable earth retaining. Further, when the retaining fence body is a net fence such as a wire mesh, the supporting and mounting of the net fence is easy due to its light weight, and the retaining is performed by the retaining sheet disposed on the back surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to illustrated construction examples. FIG. 1 shows a metal fence 2 which is applied to a slope 1 of a cut slope of a mountain, and a net fence 2 used for the fence 2 is a metal net body subjected to a corrosion-resistant processing. As shown in FIG. Short turn-back portion 21. The net fence 2
Is an inclined state such that when the folded portion 21 is placed in contact with the inclined surface, the folded part 21 is inclined slightly forward from a vertical state.

A fence holder 3 for supporting the net fence 2
As shown in FIG. 3, the holding metal fitting 31 has the same inclination as the mesh fence 2, and has a folded ground contact portion 30 at the lower end longer than the folded portion 21 of the mesh fence 2, and an upper folded end and a lower end of the holding metal 31. Insertion rings 3 respectively formed at the ends of the folded ground portion 30
An anchor 35 is inserted into and locked to 2,33.

First, the holding bracket 31 is fixed by inserting the anchor 35 through the insertion rings 32 and 33 and piercing the inclined surface 1. Next, the net fence 2 is engaged with the holding metal fittings 31 fixed at predetermined intervals in the horizontal direction to be continuous, and the folded portion 21 is formed on the inclined surface 1.
Place in After temporarily fixing the net fence 2 first,
The holding fitting 31 may be fixed.

Further, a fibrous water-permeable soil retaining sheet 4 obtained by crushing and drying palm nuts is placed on a net fence 2 as shown in FIG.
Of the net fence 2
And further placed on the inclined surface 1. Then, in this state, the base soil 5 containing seeds and fertilizer is pressed into the back side of the net fence 2.

Accordingly, as shown in FIG. 1, a greening base is formed between the upper and lower net fences 2 on the back side of the net fence 2. At this time, when a gap is formed between the inclined surface 1 and the lower end of the mesh fence 2 when the inclined surface 1 is uneven, the retaining sheet 4 at that portion is supported by the folded portion 21 of the mesh fence 2 so that the base soil can be prevented from falling. It is. Further, since the retaining fence is easily deformed flexibly due to the net fence 2, the holding bracket 3
Even if the position 1 is displaced, the deformation can be corrected and fixed to the holding bracket 31, or can be in contact with or close to the inclined surface 1.

Since the net fence 2 is in a vertical state or a slightly forward state, it becomes a base having a gentle slope, so that soil on the surface does not flow out, and a large amount of base soil can be held. It is. In addition, soil retention sheet 4
The soil can be well preserved because of the ventilation and water permeability.

The method of the present invention is not limited to this. For example, regardless of the material and shape of the earth retaining fence body, a thin plastic plate or a plate material having a large number of holes formed therein may be used. Further, the material of the soil retaining sheet is also appropriate, and the soil retaining sheet does not have to be arranged if the soil retaining fence body performs the soil retaining effect. Further, the retaining sheet may be arranged from the lower portion of the retaining fence to the turn-back portion. The configuration of the fence holder is also optional.

According to the first aspect of the present invention, the earth retaining fence can be set up in a substantially vertical or forwardly inclined state, so that a large amount of base soil can be held between the earth retaining fence and the inclined surface, and the lower part of the earth retaining fence is folded back from the lower end to the lower end. The earthing sheet placed between and closes the gap formed between the uneven inclined surface and the earthing fence, thereby preventing the soil from falling and providing a stable earthing. In addition, the load of the upper row of retaining fences is not applied to the lower row of retaining fences, so that the base soil can be reliably held. According to the second aspect, since the net fence such as a wire net is lightweight and excellent in flexibility, it is easy to support and attach the net fence, and the net fence is earthed by the earthing sheet arranged on the back surface. Claim 3
Then, the sedimentary surface of the inserted base soil becomes a gentle slope,
Can be prevented from falling off the surface. In addition, billing
Item 4 has excellent ventilation and water flow, and good soil preservation can be achieved.
