Abstract

PURPOSE:To prevent unevenness of the contained soil and its overweight so as to facilitate handling of the soil by receiving the earth, brought from another place, filled with a vegetation material, in a bag unit within a range of predetermined size, and thereafter closing an opening part to form an afforestation unit. CONSTITUTION:An afforestation unit is formed into a shape of about 5 to 10cm in thickness and about 10 to 20kg in weight by packing the earth (brought from another place) 10 in a bag unit 1. The bag unit 1 is seamed into a size of about 5 to 70cm in length and about 3 to 50cm in width by integrally connecting both side edge parts 4, 4 and a bottom part 5 of two sheets of obverse and reverse net-shaped units 2, 3 and further forming an opening part 6 in an upper part, and an eyelets 7 are mounted on four corners. Next, the earth 10 is housed in the bag unit 1 by mixing an organic material 11 of bark compost or the like in seeds and packing the earth by a water soluble sheet 12. In this way, uniform tree planting execution can be facilitated with no space in a total surface of the bag unit 1.

Description

[Detailed description of the invention] [Industrial application field] TECHNICAL FIELD The present invention relates to a green body used for ground protection, etc.

[Conventional technology]

Conventionally, this type of greening material has been used by attaching vegetation material to the inner surface of a sandbag and filling it with soil during construction.

[Problem to be solved by the invention] In the above configuration, the opening of the greening body is the entire upper end,
Especially when putting soil in at the site, the entire top end opens in a circular shape, so too much soil is put in, resulting in a weight of around 25 kg, which is heavy and the soil is concentrated towards the bottom of the bag, making it difficult to carry or otherwise handle. Therefore, construction was difficult.

Therefore, the present invention was invented to solve the above-mentioned problems.It has a uniform thickness, prevents over-filling of soil, is easy to carry and handle, and is easy to install. The purpose is to provide green bodies.

(Means for Solving the Problems) The green body according to the present invention has two net-like bodies, front and back, which are polymerized, both sides and the lower end of which are integrally joined, and eyelets are provided at the upper and lower ends of both sides. A bag is formed, and after the soil filled with vegetation material is placed in the bag, the opening at the upper end of the bag is closed.

[Effect]

In the greening body of the present invention, the opening at the upper end of the bag is closed after storing the soil in the bag, which prevents the stored soil from shifting to one side and the large bag of soil that weighs more than necessary. It is easy to carry, carry and handle, and is easy to install. Uniform greening is possible without creating any gaps over the entire surface of the bag. Moreover, the bag is filled with soil filled with vegetation material at the factory. Since it can be housed in a small amount of space, it can be kept at a certain weight and quality control can be easily performed.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In this embodiment, a bag I is woven by a loom, and the warp a for weaving the front and back net-like bodies 2 and 3, and the ears 4 on both sides.
．． In order to weave 4, the warp threads s and b are arranged more densely than the warp thread a.

The weft threads d are densely woven into the multi-threads a and b arranged as described above to form a bottom part 5 in which the front and back sides are integrated, and then the weft threads e are woven at intervals to form a net-like body 2 on the front and back sides. .3 is formed separately, ears 4.4 are formed on both sides, and finally the weft f is woven densely to form an opening 6, with a length of 5 to 70 mm.
A bag body 1 with a width of 3 to 50 cm is woven.

Attach eyelets 7 to the four corners of the upper and lower ends of the ear portion 4.4.

Each of the warp yarns mentioned above is made of, for example, polyethylene heptofilament, and the weft yarn is made of, for example, polyethylene flat yarn, but the back weft yarn is partially made of water-soluble yarn (PVA).
Or use corrosive viscose rayon.

Then, after construction of the green body, a portion of the weft threads will melt or corrode due to rain or water supply, and the polymerization on the back side of the green body will increase accordingly, causing more of the vegetation material to come into contact with the ground surface.

Further, in the above embodiments, a hollow weave is shown, but this may be formed by polymerizing five sets of knitted fabrics, nonwoven fabrics, or other net-like bodies.

The soil base 10 accommodated in the bag 1 is made up of a water-soluble sheet-like member 12 containing a vegetation material 11 consisting of organic materials such as park compost, peat moss, and vermiculite, soil conditioners, and other general chemical fertilizers. It retains its shape,
In addition, seeds 13 are mixed with the vegetation material 11. This soil board 10 is relatively lightweight as a whole, and is partially protected by a back mesh 3 with good water solubility and a surface mesh 2 with polymerization that allows plants to grow. It is housed in a bag body 1. This green body is 5 to 10 cm thick.
If the weight is about 10 to 20 kg, transportation and other handling becomes easy.

The opening 6 of the bag 1 containing the clay board 10 can be easily closed with a bostitch 8 or the like.

Then, as shown in FIG. 2, the opening 6 of the greening body is placed facing the upper side of the slope 14, and the bottom part 5 of the greening body is opened from above so that both eyelets 7, 7 are aligned. It is placed and fastened to the slope 14 using an anchor 15 or the like. At this time,
The horizontally adjacent edged bodies may also be fastened at the same time.

After that, by waiting for rain or by supplying water, the sheet-like member 12 that accommodates the above-mentioned sub-soil plate 10 is dissolved, and the restraint by the sheet-like member 12 is released, so that the structure of the above-mentioned sub-soil plate 10 is released. The adhesion to the surface 14 becomes even better, and the seeds 13 mixed in the soil base 10 germinate over time, take root in the soil base 10, and grow through the polymerization of the net-like bodies 2.3. , eventually, what will become a customer base 10
Greening of the slope 14 is achieved by penetrating the soil and taking root in the ground.

[Effects of the Invention] As described above, according to the present invention, the opening at the upper end of the bag is closed after the soil is stored in the bag, so that the stored soil does not shift to one side or exceed the necessary amount as in the conventional case. It prevents the formation of large bags of heavy soil, is easy to carry and handle, is easy to install, allows for uniform greening without creating gaps over the entire surface of the bag, and is filled with vegetation material at the factory. Since the soil is housed in the bag, the weight can be reduced to a certain level, and quality control can be easily performed.
