Description

[Detailed description of the invention] The present invention relates to a net for earth retention and vegetation.

For example, when protecting a slope in a developed area, the conventional method was to form a retaining fence with wire mesh made of wide wires and install this retaining fence on the slope. When planting grass or other vegetation on a slope, it is necessary to sow seeds on the slope after installing a retaining fence, which takes a lot of time to complete.

In view of the above, the purpose of the present invention is to provide a soil retaining and vegetation net that can perform soil retaining and seed sowing at the same time. It is characterized by having a substantially L-shaped cross section, and holding seeds for greening on the bent edges of the filaments.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In FIG. 1, 1 is a slope, 2 is a retaining fence installed on the slope 1, and the retaining fence 2 is
is a net 3 formed by vertical and horizontal filaments 5 and 6.
and a large number of triangular support members 4 made of strong wire, and the net 3 is stretched and supported between the support members 4 arranged at regular intervals.

Of the vertical and horizontal filaments 5 and 6 constituting the net 3, the horizontal filament 6 is formed by embedding a wire 8 in one side end of a synthetic resin band-like covering 7, as is clear from FIG. It is formed into a wide shape by forming a bent edge 9 in the length direction on the other end of the belt-shaped covering 7, and seeds 10 of plants such as grass are placed and held on the bent edge 9. The structure is such that the slope is greened by the germination.

When holding the seeds 10 on the bent edge 9, the seeds 10 may be placed directly on the bent edge 9 and held by adhesive or the like, or the seeds may be held on a holding body such as tape or a porous straw. This holder may be placed and fixed on the bent edge 9.

3A and 3B show other embodiments of the wide filament in the net 3. The one shown in A has the bent edge 9 formed in a hook shape, and the one shown in B has the center of the band-like covering 7. A wire 8 is embedded in the part.

In the earth retaining fence 2 of the above embodiment, the earth and sand on the slope 1 is caught on the bent edge 9 of the horizontal line 6 and is reliably supported, thereby preventing it from sliding down or moving.

In addition, the seeds 10 on the bent edge 9 in the filament 6
germinates and grows by ingesting moisture and nutrients from the soil,
As a result, the slope 1 is protected by earth retaining and vegetation at the same time.

Note that the above-mentioned net 3 is not always used in the manner shown in FIG. 1, but as shown in FIG.
It goes without saying that it can be used in any manner depending on the installation conditions, such as by being stretched between the slopes 1 or by embedding part or all of it within the slope 1.

As described above, according to the net of the present invention, one of the vertical and horizontal lines constituting the net has a substantially L-shaped cross section with a bent edge at the side end, and seeds for greening are placed on the bent edge. Since the structure is placed on the ground, earth retaining and vegetation can be done at the same time just by installing it at a predetermined location, and slope protection work involving vegetation can be reliably carried out with fewer steps.
