Abstract

PURPOSE:To efficiently perform the protection and tree planting of a face of slop by molding a sheathing net to be laid on a banked slope to prevent its rupture and a fixing tool thereof from a biodegradable plastic containing manure components, and weathering it after growing a plant to form a manure. CONSTITUTION:A sheathing net 3 for preventing the rupture of a banked slope and a net fixing tool 3 are formed of biodegradable plastic materials 1, 1' containing manure components such as starch, nitrogen, phosphoric acid and potassium. The sheathing net 2 is fixed onto a banked slope 4 by the net fixing tool 3, and a lawn or grass 5 is vegetated. After the plant 5 is grown, the net 2 and the net fixing tool 3 are weathered into a manure to accelerate the growth of the plant. Thus, the protection and tree planting of the face of slop can be efficiently performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earth retaining net which is stretched on an embankment slope or a slope to prevent collapse and a stopper therefor.

[0002]

2. Description of the Related Art Conventionally, a porous rubber sheet or a plastic material connected in a block shape is stretched or covered on a slope or slope of an embankment, and this is fixed to each other or to the soil surface with a wire or a nail. And on top of that, lawns and grass are planted on the soil surface to prevent the slope from collapsing.

However, rubber and plastic are difficult to corrode,
Has a semi-permanent life. Also, when mowing, the nails and wires damage the blade of the mowing machine and are dangerous for walking, and the rubber sheets and plastic materials interfere with the growth of lawns and grasses, breeding and breeding, or topographic change work. There was a problem that it would occur.

[0004]

SUMMARY OF THE INVENTION The present invention covers the slopes and slopes of an embankment, and when the slopes and slopes of the plastic soil retaining nets and their fasteners for securing lawns and grasses on the soil are stable. It is intended to decompose and disappear, and to give lawn and grass fertilizer to the soil surface.

[0005]

In order to achieve the above object, the present invention is a net formed of a plastic material, wherein the plastic material is mainly composed of biodegradable plastic and contains a fertilizer component. The soil stopper net, which is a fertilizer, is a fertilizer such as starch, nitrogen, phosphoric acid, potash, etc., which is a net stopper instead of the soil stopper net described in the above invention. Consists of a net stopper for earth stop.

[0006]

In the present invention, lawn or grass 5 is planted on the slope or slope 4 of the embankment or cut-off surface and is covered with the net 2, or the net 2 is stretched on the slope or slope 4, and then the lawn or grass is cut. 5 is covered and planted, the nets 2 and 2 are connected to each other by the fastener 3, or the fastener 3 is pierced on the slope or the slope 4 to fix the net 2 to the ground. In this way, the lawn or grass 5 grows from the mesh 2 ', or the root enters the ground from the mesh 2'and the net 2 is covered by the grass or the grass 5.

Until the slope or slope 4 is stable and the lawn or grass 5 has fully settled, the net 2 and the stopper 3 serve to prevent the slope and slope 4 from collapsing, and thereafter the net 2 and the stopper 5 are stopped. The biodegradability of the plastic materials 1, 1 ′ forming the ingredient 3 hydrolyzes, and the fertilizer content in the plastic materials 1, 1 ′ promotes the growth of lawns, grasses 5 and the like.

[0008]

EXAMPLE A rod-shaped plastic material 1 having an outer diameter of 8 to 10 mm,
1'is arranged in the back and forth, and the intersecting portions 1 "are welded to each other to form an integral mesh 2. The mesh 2'has a length of 15 to 20 mm.

The above-mentioned plastic materials 1 and 1'are made of biodegradable plastic as a main material and contain a fertilizer component such as starch, nitrogen fertilizer, phosphate fertilizer or potassium fertilizer.

Biodegradable plastics are sold by Nippon Synthetic Chemical Industry Co., Ltd. under the trade name of "Matterby". Starch, which is a natural polymer substance, and modified polyvinyl alcohol, which is hydrophilic and biodegradable. Is a composite resin containing as a main component, both of which have OH groups in the molecule, and these are strongly bonded at the molecular level by hydrogen bonds, resulting in IPN (Interpenetrated Polymer Network).
It is a homogeneous alloy (mixture) forming a structure. Also, hydrolyzable urethane can be used.

Further, a hail-shaped or hook-shaped stopper 3 is formed of the plastic material 1 made of the above-mentioned components, and the nets 2 and 2 are connected to each other as shown in FIG. 2 or 2 is fixed, or the rod-shaped plastic material 1 or 1'is hooked on the stopper 3 for each net 2 and the stopper 3 is pierced into the ground in that state to It can be fixed to the slope or the slope 4.

The lawn or grass 5 can be planted below or above the net 2, and the net 2 is obscured by the growth of the lawn or grass 5. Then, the net 2 and the stopper 3 are stretched to form 2
After a lapse of 6 years, it completely returns to the soil and disappears, and the fertilizer component promotes the growth of the lawn or the grass 5. The slope or the slope 4 is a tee ground of a golf course, an embankment slope of a road or a cut surface. The thickness of the mesh plastic materials 1, 1 ', the size of the mesh 2', etc. of the mesh 2 can be freely selected.

[0013]

Since the present invention is constructed as described above, the strong net 2 made of the plastic materials 1 and 1'and the fasteners 3 strongly support the lawn and grass 5 planted on the slope or slope 4. In addition, the slope or slope 4 can be stabilized, the decomposition and disappearance can be performed along with the stabilization, and the lawn, the grass 5, and the like can be fertilized, and damage to the mower can be prevented.
