Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a vegetated sandbag that is easy to handle during construction and has a rectangular shape after construction, allowing for more reliable greening than conventional sandbags. .

(Conventional technology) Land development has become active in recent years, and it is regulated to leave bare land unattended, and restoration work is required from the perspective of environmental conservation. Vegetated sandbags are an application of the soil-removal method for greening work, and are a combination of sandbags and vegetated grass, making a major contribution to the restoration of nature.

However, when conventional vegetated sandbags are filled with soil,
Because the openings were narrowed and tightened, their shapes became rounded, and when they were constructed side by side, there was a problem in which gaps were created in the corners of the sandbags, making it impossible for complete natural recovery.

For example, Japanese Utility Model Publication No. 42-18919 states, ``In a net bag, a seed plate formed by kneading and adhering seeds with a compound on the surface of a porous protective sheet is placed.
A greening bag has been proposed which is a combination of a seed plate and a net bag, which are made by filling the net bag on the back side of the seed plate with manure. Since it cannot be closed without using a stopper, it is difficult to work with.

(Problem to be solved by the invention) This invention was made to solve the above-mentioned problems, and the problem to be solved is how to eliminate the voids that were created between sandbags. The question is whether a complete vegetated surface can be formed.

The purpose of this invention is to make it easy to fill in soil and close the opening, to prevent the soil from spilling out, and to ensure that the sandbag has a rectangular shape after completion. The purpose is to provide a vegetation sandbag with a simple configuration that is close to that of the original greenery and allows complete greening work to be carried out.

(Means for Solving the Problems) In the present invention, if the embodiment shown in the drawings is explained based on the drawings, the upper end of the bag body 1 shown in FIG. Both ends are joined to the bag body 1 as shown in the seam portion 5 in FIG.
Reference numeral 3 denotes a vegetation zone, which is attached to the inner back side of the front surface of the bag body 1.

That is, the vegetation sandbag according to the present invention is a bag body constructed by folding a bag base material having a mesh size that allows plant seeds to germinate in half so that the fold becomes the bottom and sewing both sides of the bag base material. 1, the upper edge of one side of the folded bag base material is extended from the other side to form a folded part 2, and this folded part 2 is folded to the outside of the bag body 1. Both left and right edges of the bag 1 are sewn to the bag 1 by stitching parts 5 that stitch both sides of the bag 1, and a vegetation strip 3 is attached to the inside of the bag 1.

What is important here is to make the folded part 2 sufficiently long, and to sew both left and right edges of the folded part 2 to the left and right sides of the bag 1 using the stitching parts 5 that also stitch both sides of the bag 1. It is. As will be described later, when soil is put into the bag body 1 and the folded part 2 is folded back to close the opening and the lid is closed, the seamed part 5 increases the left and right elasticity of the folded part 2 and the bag body. It also prevents the opening of No. 1 from stretching easily.

In addition, this vegetation sandbag is made from a single bag base material.
As shown in FIG. 5, first, it is folded in half so that one side is longer, and the longer part is further folded to form the folded part 2. Of course, at this time, the vegetation band 3 is attached to the inside of the bag base material on the folded portion 2 side. Then, by sewing the left and right sides of the bag base material together with the folded portion 2, the bag body 1 as shown in FIG. 1 is obtained.

(Aspects of operation and use of the device) The method of using the vegetation soil bag having the structure as described above is that before filling with soil, the folded part 2 is located on the opposite side of the bag body 1 as shown in Fig. 3. Because of this, the mouth opens wide and filling with soil is extremely easy.

Once the soil has been fully pressed in to the mouth, the folded part 2 is placed in its normal position as shown in FIG. 2 (the folded part 2 is on the opposite side beyond the opening of the bag 1). With the above operations, soil packing is completed.

The most significant effect of this invention is that both the left and right ends of the folded part 2 are joined with the left and right ends of the bag body 1 by the seam part 5. In some cases, it is possible to open the bag 1 wide as shown in Figure 3, but it is also possible to fill the bag 1 with soil and fold back the folded part 2 as shown in Figure 2 to spread the soil uniformly throughout the bag. When the soil is opened, the soil expands to the full extent at the opening of the bag, and the edges become square and high, and at the same time, the lower part of the folded part 2 is pressed by the pressure of the bag 1, causing the soil to leak out. is prevented. In addition, a stopper 6 is provided to connect the folded portion 2 to the bag body 1 to further increase the effect of preventing soil leakage. The fastener 6 may be any suitable material such as a snap or a hook.

(Effects of the invention) Therefore, by using the sandbag of the present invention, it is easy to fill the sandbag with soil, there is no leakage of soil during handling, and during construction, the sandbag has a nearly rectangular shape up to the corners. When completed and laid, there are no gaps between the sandbags, making it possible to carry out complete greening work, so this is a truly meaningful idea.
