Abstract

PURPOSE:To easily and exactly perform a greens-planting work by a method in which vegetation bags, e.g., sand bags, etc., are laid, and slurried soil is pumped up and mixed with a coagulant and then packed with stirring into the vegetation bags. CONSTITUTION:Vegetation bags 1 of a woven fabric of a coarse mesh are laid in divided frames of the ground 2 to be treated, e.g., sloped ground, etc., and slurried soil is sent under pressure to the ground 2 through a hose 4 by means of a pump. The slurried soil sent is then mixed with a coagulant, e.g., polyacrylamide, sodium polyacrylate, etc., sent under pressures through a hose 6 from a mixing nozzle 5 by a pump and packed into the vegetation bags through their openings. The soil packed is quickly coagulated and dewatered, and at the same time the vegetation bags 1 are closely adhered to the surface of the ground. The germination of plant seeds in the vegetation bags is made easier, thus making the greens-planting work exact.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of constructing a vegetation bag for use in mountain conservation work, civil engineering work, etc.

In the current construction of conventional vegetation bags such as vegetation sandbags, soil is filled into the bag on level ground and then transported to the construction site by hand or by a conveyor.

However, this method not only requires a great deal of labor, but also has the disadvantage that the vegetation bag may be damaged during transportation, or the filled soil or seeds or fertilizers that have adhered to the bag may spill out through the mesh of the bag. If the soil falls off, the top surface of the bag after being placed will be separated from the soil surface.
Seeds attached to the vegetation bag may dry out, resulting in poor germination, or even if they germinate, it is difficult to pass through the mesh of the bag.
In particular, the top surface of the vegetation bag is lifted further away from the soil surface by the leaves of clover and other plants that germinate for the first time.
Even grasses of the East family, which are easy to form buds, have defects that make it difficult for them to form buds and inhibit vegetation.

The present invention aims to improve these deficiencies by laying vegetation bags such as vegetation sandbags on the construction site, transporting the muddy soil to the construction site using a pump, and applying a flocculant before filling it. The gist is to fill the vegetation bag while mixing and stirring.

When using the method of the present invention, vegetation bags are laid on the construction site in advance and the muddy soil is transported and filled with a pump, so
Vegetation bags can be laid and planted efficiently without requiring labor or causing soil, seeds, fertilizers, etc. to fall off, and by mixing a flocculant immediately before filling the vegetation bags, the filled muddy surface can be It quickly flocculates, becomes hydrophobic and dehydrates, and at the same time brings the vegetation bag into close contact with the soil surface, making it easier for seeds to sprout through the vegetation bag to ensure proper vegetation. It creates voids and aggregates soil to form an ideal vegetation base.

The vegetation bag in the present invention refers to a vegetation sandbag or other mesh-like vegetation bag, and the inside thereof can be divided into small bags as needed, and the vegetation bag can be laid inside a vegetation gabion instead of being laid directly. You can also do that.

In addition, as the flocculant used in the present invention, polyacrylamide type, polyacrylic acid sodium etc. having a high molecular weight are suitable, and when dissolved at about 0.02% in water, about 10% of the flocculant is added to the slurry. Immediately before filling To specifically explain the details of the present invention, a vegetation sandbag or other vegetation bag (1) made of round woven cloth or the like is placed in a field frame (3) of a construction site (2) such as a slope or slope. ), the muddy soil is pumped to the construction site (2) using a muddy soil supply hose (4), and at the same time, a flocculant is applied to the mixing nozzle (5) at the tip of the muddy soil using a pump. The liquid is pumped through a feeding hose (6), mixed with muddy soil, and then filled through the opening of the vegetation bag (1). Then, as the mud coagulates, it becomes hydrophobic and the volume of the soil inside the vegetation bag (1) decreases a little, but the woven fabric on the surface of the vegetation bag (1) adheres closely to the soil surface and does not separate from the soil (but Appropriate voids are created inside the bag (1) and the seeds aggregate to form a good vegetation base, and the seeds grow through the mesh of the vegetation bag (1).

Seeds, fertilizers, etc. may be allowed to adhere to the vegetation bag (1) in advance, or may be mixed into the muddy soil (3).

Example After laying vegetation bags with vertical partitions made of round woven fabric on the construction site on the slope, Kanto loam soil Q, 5 m'
, Park compost 0.6 m", water 1000A, Kentara Key 31 Huesque i, zKy, white clover-0,2
Ky, Weaving Love Glass 0.2 Ky, chemical fertilizer 10 parts to 2 parts are mixed to produce muddy soil, and this is pumped to the construction site using a muddy soil conveying hose, and at the same time, the polyacrylamide part is added to the mixing nozzle. An aqueous solution in which 0.02% of the hydrolyzed product was dissolved is injected and filled into each of the laid vegetation bags while mixing 10% of the muddy soil.

In addition, in order to compare the germination and germination status between the conventional construction method and the present invention, seeds and fertilizers of the same type and amount were filled into vegetation bags of the same size. The germination and number of buds of the present invention and those transported and laid by hand at the construction site 20m above were investigated, and the results were as shown in Figure 6.
