Description

[Detailed description of the invention] Industrial application field This invention relates to soil bags for slope protection, and is useful for various civil engineering projects such as greening of highly acidic soil, wasteland lacking fertilizer, or narrow mountainous areas. It is used when performing greening work accompanying construction work.

BACKGROUND OF THE INVENTION Conventionally, as a device corresponding to this type of soil bag, for example, the device disclosed in Japanese Utility Model Publication No. 8105/1983 is known.

The above-mentioned invention is used when installing temporary embankments and slopes for emergency restoration work of collapsed or landslided banks and roads.

However, because the cloth bags used for this soil constantly retain moisture, existing sandbags quickly corrode and the soil collapses, making them often ineffective as a barrier.

Therefore, in order to eliminate such defects, the invention aims at providing a sandbag bag which prevents the collapse of the earth and sand filled inside.

Problems to be solved by the invention Therefore, in the conventional invention, the bags used for sandbags are made of natural or chemical fiber materials, and the bags made of chemical fibers do not rot, so they can be used for bank protection work, etc. It has the advantage of being highly functional.

However, in greening work like the one proposed in this application,
If the bags do not rot and remain as remains, the natural landscape will be spoiled.

Further, in the above-mentioned invention, since the bags are stacked in multiple stages, if the seeds are placed on the flat surface of the bags, germination may be inhibited by the stacking pressure.

This invention is provided in order to solve the above-mentioned conventional problems, and it is possible to maintain a large soil thickness inside the soil bag used for greening work, and to prevent the soil from flowing out and scattering during the curing period of seeds. The purpose of this project is to prevent soil damage and to obtain soil bags that are designed to ensure that no trace of the construction work is left behind.

Means for Solving the Problems In order to solve the above-mentioned problems and to further achieve the purpose of the invention, the present invention has been devised to solve the above-mentioned problems and to further achieve the purpose of the invention. Pre-mixed seeds and fertilizer are attached to almost the entire surface of the back side using a pure vegetable adhesive, and a colored display section is provided on the front side of the single side to indicate the position where the seeds and fertilizer are attached.

action The functions of the present invention are as follows.

First, when constructing a soil bag, fill the container with black soil, leaf mold, or other soil suitable for plant growth, fold the opening to the side opposite the display area, and seal it by tying it with a straw rope for sealing. .

Next, excavate the place where the slope will be installed to the extent that the container will not slide off, place the container there with the display facing up, apply pressure with your feet to make it into a flat plate, and then use wooden stakes or bamboo Insert an anchor pin such as a skewer into the container and drive it in at right angles to the slope surface to complete the installation.

EXAMPLE Below, an example of the present invention will be described. Seeds 2 and fertilizer 3 mixed in advance are spread over almost the entire back side of a flat container 1 and one side 1, which are rotatable over a period of time, using pure vegetable adhesive 4. The device is equipped with a colored display section 5 on the front side of the single side to indicate the position of the seed/fertilizer attachment.

Furthermore, an indicator 5 indicating the position where the seeds/fertilizers are installed is provided on the front side of one side of the container (1□), and additional soil 8 is placed inside the container.
The opening 6 is then sealed with a sealing tool 7.

The material of the container 1 is straw or hemp, which is easily perishable in a relatively short period of time.
cm, length 100 cm, make a cross section, fold it in half to make 1□, 1□, sew both ends 13, and make 80 cm width.

Make a horizontally long bag with a length of 50cm.

and seeds for greening (Kentara Key 31 Fuesque, Weaving Love Grass, Creepinda Red Fuesque, etc.)
2 and fertilizer (granular solid, urea chemical, etc.) 3 are installed when the container 1 is in a dry state, and on one side 1 □ of the container 1, apply a pure vegetable adhesive mixed with konjac powder, fiber (woody cellulose), and water. Install it at 4.

Further, the display section 5 may be colored by lightly spraying green paint, for example, on the surface opposite to the position where the seeds/fertilizers are attached.

Effects of the invention Since the present invention has the above-mentioned configuration, seeds and fertilizers are attached to almost the entire back side of the top surface of the container, and a mark is provided on the opposite side of the attachment position to ensure that the seeds are placed on the upper side during construction. It can be installed in a manner that allows a thick layer of soil to be obtained and germination can be obtained over the entire surface of the container.

Therefore, effective growth and flourishing of plants can be achieved even on slopes such as highly acidic soil or wasteland lacking fertilizer.

In addition, the straw material in the container has a heat-retaining effect, which promotes germination.

Furthermore, because the container is made of straw and has a bag body, there is less scattering and runoff loss of soil and seeds due to wind and rain compared to the conventionally popular polyethylene net bags.
Over a relatively short period of time, the container and rough rope will rot, making it an excellent compost and leaving no trace of the construction work after completion, so it will not damage the natural landscape.

Since the seeds and fertilizer are attached to the container in advance with a pure vegetable adhesive, they can be stored without filling with soil, and are lightweight and convenient to transport.The adhesive also prevents konjac powder from flying. Since it contains pure plant ingredients, it also serves as a fertilizer.

Moreover, since the container is manufactured in a factory, seeds can be freely selected and mixed according to the order of the construction owner.

During construction, all you need to do is fill in the soil near the site, making it easy to carry, and it is extremely efficient since there is no need to mix seeds, fertilizer, and soil as in the past.
