DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope planting protection device for preventing plants planted on an inclined ground from flowing out due to heavy rain or the like.

[0002]

2. Description of the Related Art In a region where the ratio of mountains is high and there are many slopes as in Japan, for example, when constructing a road or the like, it is very common to artificially cut the slopes obliquely according to the construction plan. . When such construction work is performed,
If the shaved ground is a place where plants were growing, efforts to restore the natural vegetation before the construction by planting seedlings such as plants growing on the ground before being shaved on the newly formed slope Have been paid. However, even if plant seedlings are planted on such an inclined surface, the planted seedlings are often washed away when a large amount of rain falls due to the inclined surface. Therefore, it is required to stabilize the slope while preventing the seedlings planted on such a slope from being washed away. On the other hand, in the field of forestry, there is no effective way to use the thinned wood generated in large quantities by thinning, and disposal thereof is a problem.

[0003]

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a slope planting protection device for protecting a seedling planted on a slope from flowing out by using thinning material. The purpose is to protect plants planted on the surface, protect the sloping surface, and solve the disposal of thinned wood at a stretch.

[0004]

According to the first aspect of the present invention, there is provided a slope planting protection device for preventing seedlings planted on a sloped ground from flowing out. In the horizontal direction, the ends in the longitudinal direction are abutted and arranged continuously.In the vertical direction along the inclined surface, they are spaced apart at a predetermined interval, and the horizontal position of the abutment in the vertical direction is the same. It consists of a plurality of crossbars that have been cut and thinned lumber cut to a length equal to the vertical interval along the slope of the crossbar, and is arranged so as to connect the butting parts of the adjacent vertical bars, and cooperates with the crossbar A vertical tree forming a plurality of rectangular planting sections, and a connecting member for connecting the ends of two crossbars and two vertical trees gathering at the abutting portion and fixing the ends to the ground, and planting. Formed at predetermined intervals on the slope just above the crossbar in the section The hole of 栽用, inclined surfaces planting protective device consisting of are provided.

[0005] Preferably, the crossbars at the same vertical position and / or the vertical bars at the same horizontal position are connected by connecting means in the longitudinal direction, so that the longitudinal connection can be strengthened. In that case, the connecting means is a wire,
It may be a groove formed in a crosspiece and / or a vertical piece that receives the wire.

If the crosspiece is composed of a plurality of crosspiece elements made of thinned wood, and the vertical tree is composed of a plurality of vertical wood elements made of thinned wood, it is possible to contribute to the effective use of the thinned wood.

[0007] A crossbar is constructed by stacking six crossbar elements in the order of three, two, and one from the side closer to the ground, and forming a vertical bar with six vertical tree elements, three from the side closer to the ground. By arranging two trees and one tree in this order, it is possible to form a compact and upper horizontal and vertical trees.

Further, the strength of the cross-bar element and the vertical-tree element can be increased by being clamped in the middle of the longitudinal direction by an intermediate clamping member. Further, if the intermediate fastening member is fixed to the ground, the strength is further increased.

[0009] Further, if a sub-street is arranged between the vertically adjacent cross-trees, and planting holes formed at predetermined intervals are provided on the inclined surface immediately above the sub-street, more seedlings can be planted. be able to.

If the connecting member is made of a metal which is easily rusted, it returns to its natural state, so that it is not necessary to remove the connecting member manually. If the connecting member is a covering means, the appearance is improved. The appearance is further improved if the connecting member is hardened with the coated solidified molding material and its outer surface is pseudo-painted with a color close to the surrounding vegetation.
