Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming pine for vegetation in soil covering work for river revetments, embankments, embankments, land reclamation, etc.

Conventional soil covering work uses methods such as turf laying, stone masonry, and concrete block laying.

It is difficult to obtain a large amount of grass at once, and growing and maintaining it is extremely time-consuming. Furthermore, it cannot be applied when the construction surface is a steep slope because the grass has poor fixation and is easily washed away.

Also, masonry or concrete block laying can be applied to steep slopes, but it requires a lot of cost to transport large quantities of stones and concrete blocks. Furthermore, since stones and concrete blocks are likely to become unstable during construction, there is also a problem in terms of construction safety.

In addition, as a method of covering slopes with soil and making them green,
There is a method of spraying soil and seeds with an adhesive, but the problem is that the adhesive peels off when it rains, the seeds have poor fixation, and they flow downward.

In recent years, a method using soil-covering pine has become known as a construction method that allows soil-covering work to be carried out extremely easily and inexpensively. In this construction method, a soil-covering mat, which is a cloth bag-like material, is spread over the construction surface, and a fluid filler, such as mortar, is injected into the mat and solidified to cover the construction surface.

This construction method is much easier to construct than conventional methods such as turfing, stone masonry, and concrete block covering, but the disadvantage is that the appearance after construction is similar to that of just poured cement, which gives it an extremely strange appearance. There is.

In view of these drawbacks, the present invention has developed a vegetative pine that can be used permanently, not temporarily, for the purpose of greening the soil-covering surface and preventing collapse, while taking advantage of the advantages of the construction method using soil-covering pine. This is the formation method.

That is, the present invention provides a slurry made by mixing a soil suitable for vegetation, a slowly water-soluble fertilizer, and seeds in water of 20% or more of the soil weight to give fluidity, and having two layers of water permeability and flexibility. The soil particles are press-fitted into a bag-like material, and a filter bed is formed by the soil particles in the gaps between the yarns that make up the bag-like material, and excess water is drained to fill the bag-like material with soil, fertilizer, and seeds that are suitable for vegetation. This is a method for forming a pine for vegetation, characterized in that a pine for vegetation is formed by leaving the pine for vegetation.

The present invention will be specifically explained below based on the drawings. FIG. 1 is a plan view of the bag-like article of the present invention, and FIG. 2 is a cross-sectional explanatory view showing an example of the embodiment. The pine for vegetation obtained according to the present invention consists of a soil suitable for vegetation, a filling consisting of a slowly water-soluble fertilizer and seeds, and a fabric bag.The bag 1 is made of synthetic fiber, for example, a single-ply bag. It is made of a fabric in which woven parts and double woven parts are alternately woven, or a non-woven fabric, with filter points or pile driving holes arranged appropriately in the middle. By injecting a fluid filler into the bag-like article having such a structure, the filler can maintain a uniform thickness as a whole and form a wide surface along the laying plane.

The fabric forming the bag-like article is made of woven or knitted fabric, non-woven fabric, etc., and has voids so that the filling material is retained inside and only excess moisture is discharged from the fabric's openings.

The filling to be injected into this bag-like material is a fluid slurry consisting of 2 soils suitable for vegetation, 3 slowly soluble fertilizers, and 4 seeds.
Preferably, the soil is mixed with 50% or more of water and stirred, so that the seeds and fertilizer are uniformly dispersed in the soil and have fluidity. If the amount of water to be mixed is less than 20% by weight based on the soil, the fluidity will be poor and the slurry will not form, making it difficult to press into the bag. In this case, the soil pot 2 suitable for vegetation is not particularly limited, but a soil pot suitable for seeds is selected and used depending on the type of seeds to be used.

Slowly soluble fertilizer 3 is, for example, a fertilizer component consisting of ordinary nitrogen, phosphoric acid, and potassium whose outside is coated with resin so that when the coated fertilizer mixes with water, it slowly dissolves. This is what I did. When ordinary fertilizer is mixed with water to form a slurry, it dissolves at the same time, making it unfavorable for seed germination.

Further, the seeds 4 to be used are not particularly limited, but any seed may be used as long as it achieves the purpose of greening the covered soil. For example, grass, clover, etc. are suitable.

The pine for vegetation of the present invention is formed by injecting a fluid slurry into a bag-like material during on-site construction.

The bag-like article according to the present invention is made of fibers with high tensile strength such as cotton, hemp, nylon, polypropylene, vinylon, vinyl chloride, polyamide, polyester, polyacrylic, polyolefin, vinylidene chloride, etc. Sometimes, when a fluid slurry is injected under high pressure, a filter bed is formed by soil particles in the gaps between the constituent fibers, and only excess water is discharged, and the soil, fertilizer, and seeds flow out to the outside. It is best to have your eyes closed so that there are no tears.

The method for forming a pine for vegetation of the present invention having the above configuration has the following effects.

The slurry made by mixing soil, fertilizer, and seeds with 20% or more of the soil weight in water to make it fluid can be injected into bags, making it easier to fill bags. .

Fertilizer and seeds can be evenly distributed in the soil for injection in slurry form.

Since the soil, fertilizer, and seeds remain in the bag, it is possible to suppress the elution of the active ingredients of the fertilizer due to mixed water, rainwater, etc., prevent concentration disturbance of the fertilizer, and maintain the effect for a long period of time.

Furthermore, the vegetation pine that has been constructed on-site by the vegetation pine forming method of the present invention brings about the following effects.

A: Since the vegetative pine obtained by the present invention has natural green vegetation on its surface, the appearance after construction,
For example, it is similar to covering with soil by turfing, and it can be made completely natural.

B Also, the roots of the plants grow out from the fabric on the bottom surface and penetrate into the base, and are integrated to hold the vegetation pine and have strong strength after construction.

C Also, as in B above, it can be used permanently by being integrated with the base, for example, for natural grass vegetation.
