As a packaging bag for the grounding resistance reducing agent, a polyethylene bag or a bag made of polyethylene and an outer bag made of a kraft paper bag is generally used. After the grounding resistance reducing agent is put in and installed, the packaging bag in which the reducing agent was packaged will remain, and the used packaging bags will be taken home from the construction site and disposed of, resulting in poor workability and usability. Had a problem. In particular, in the case of power transmission grounding work, a power transmission tower is also installed in a mountainous area, and transporting the equipment for grounding work to the mountainous area requires a great deal of labor.

The packaging bag of the present invention can be used by putting a grounding resistance reducing agent therein and sealing it using heat sealing or the like. In this case, in order to avoid deterioration of the grounding resistance reducing agent due to sunlight or the like, it is preferable to use a colored packaging bag so that sunlight or the like does not directly hit the contents of the grounding resistance reducing agent. The method of coloring the packaging bag is not particularly limited, but, for example, a composite of lignin and biodegradable polyester is colored and is preferable because it has a light-shielding property and an ultraviolet absorbing effect. In addition, the composite of yeast and biodegradable plastic is also colored, and can be used as it is because the decomposition rate in soil is high.

Although only the bag containing the biodegradable plastic may be used alone as the packaging bag, the packaging bag is broken by a sharp projection or the like at the time of transportation or the like, and the content of the grounding resistance is reduced. The agent may be scattered. Therefore, it is more preferable to use biodegradable plastic for the inner bag and kraft paper for the outer bag, since the durability against the breakage of the packaging bag can be increased. In addition, when an uncolored biodegradable plastic is used, deterioration of the grounding resistance reducing agent due to sunlight or the like can be avoided by using kraft paper for the outer bag. As the outer bag of kraft paper, a kraft paper bag which is generally marketed and used as a cement bag may be used.

The workability of the inner bag made of biodegradable plastic is very good if the grounding resistance reducing agent is packed in a biodegradable plastic bag sealed on one side and the upper part is sealed with a band or the like. Specifically, from the outer bag made of kraft paper,
Take out the biodegradable plastic inner bag containing the reducing agent, put the grounding resistance reducing agent into the grounding groove from the inner bag and construct it, or mix the reducing agent in the inner bag with water and put it in the grounding groove -Can be constructed and workability is very good. Alternatively, the biodegradable plastic inner bag containing the reducing agent may be put into the grounding groove as it is, and the grounding rod may be pierced for construction. The kraft bag may be buried in the soil similarly to the biodegradable plastic, and is naturally decomposed. Therefore, the kraft bag is safe without fear of environmental pollution of the soil.

The packaging bags (inner and outer bags) were buried in the soil. This allows
There is no need to take the bag back from the site, and the workability of using the grounding resistance reducing agent has been greatly improved.

COMPARATIVE EXAMPLE 1 Using a packaging bag for a grounding resistance reducing agent made of a colored plastic bag made of polyethylene, a grounding resistance reducing agent was charged and sealed in the same manner as in Example 1. After the use of the grounding resistance reducing agent, the packaging bag was brought back from the enforcement site. Since the packaging bag was bulky, taking it home from the mountain was very inconvenient.
Also, it was necessary to dispose of the returned packaging bags as garbage.

Comparative Example 2 Using a packaging bag for a grounding resistance reducing agent composed of an inner bag made of polyethylene and an outer bag made of kraft paper, a grounding resistance reducing agent was charged and sealed in the same manner as in Example 2. After the use of the grounding resistance reducing agent, the packaging bag was brought back from the enforcement site. Since the packaging bag was bulky, taking it home from the mountain was very inconvenient. Also, the packaging bag that had been brought back had to be disposed of as garbage.

By using the grounding resistance reducing agent package of the present invention, the packaging bag can be buried in the soil after the grounding resistance reducing agent is applied, and it is necessary to take it back from a construction site such as a mountainous area. It is clear that workability and usability are greatly improved. Furthermore, since the packaging bag for a grounding resistance reducing agent of the present invention is decomposed by microorganisms existing in nature such as soil, it is very environmentally friendly.
