JP 2003-105734 A JP 2008-50940 A

Conventional sandbags (bags for civil engineering work) have the following problems.
<1> When the sandbag is exposed to the sun, the material of the sandbag is heated and becomes hot.
When the entire sandbag is black, it absorbs ultraviolet light and visible light too much and the material temperature rises, so we deal with it by mixing a large amount of heat-resistant agent into the material of the sandbag. As a result, it reaches a high temperature of 60 to 70 ° C.
Generally, when the temperature rises by 10 ° C., it is said that the deterioration of the sandbag doubles, and there is a need for a review of measures against temperature deterioration for the sandbag.
<2> Cases in which small animals such as crows damage sandbags in search of food residues have been reported.
Although the sandbag is made of a material that neither humans nor small animals can see, the crow and other small animals hurt the black sandbag based on the learning effect of the black garbage bag containing food residues. Guessed.
In general, the service life of sandbags is mainly assumed to be deteriorated by ultraviolet light, and is not assumed to be damaged by small animals.
Therefore, since the entire sandbag is black, it is difficult to find a damaged part even if it is damaged by a small animal such as a crow, and if the sandbag is damaged by a small animal, the service life of the sandbag is adversely affected.
<3> In general, black tends to give a sense of pressure, so if you use black large sandbags in mountainous areas with many greens, you will not be familiar with the surrounding scenery, but you will see them when you see them in busy urban areas. It is easy to give an uncomfortable feeling.
<4> Black large sandbags containing radioactive decontamination materials have been repeatedly reported through TV, newspapers, etc., so that all black sandbags are erroneous as if they were dedicated bags for radioactive decontamination materials. Impressed.

The present invention has been made in view of the above points, and an object thereof is to provide at least one of the following civil engineering bags.
<1> Improving the service life of bags for civil engineering work by suppressing damage caused by small animals while improving the problem of temperature degradation.
<2> To be familiar with the surrounding landscape and to alleviate the aversion of those who see civil engineering bags.

The civil engineering bag of the present invention comprises a bag body using a woven fabric and a suspension belt for hanging the bag body, and a plurality of suspension hands are formed on a part of the suspension belt attached to the bag body. The bag body is a civil engineering bag body in which the bag body and the suspension belt are colored in a similar color, and the similar color is a green color.
By making the entire bag for civil engineering work green, it can improve the durability against temperature degradation and the damage caused by damage from small animals, greatly extending the useful life of the bag for civil engineering work. it can.
It is only necessary that the woven fabric constituting the bag body and the suspension belt be formed in a green color.
In order to form the entire civil engineering bag body in a green color system, the warp yarns and the weft yarns constituting the woven fabric may be colored green color in advance.
Further, a suture thread colored green may be used for sewing.

The present invention has at least one of the following effects.
<1> The problem of temperature deterioration and the damage damage caused by small animals can be improved simply by making the entire bag for civil engineering work a similar green color.
Therefore, the service life can be greatly extended as compared with the conventional black civil engineering bag.
<2> Green-based civil engineering pouches are easy to adjust to the surrounding landscape when used not only in urban areas but also in mountainous areas, and because green colors have a different color from black, those who see civil engineering pouches Can alleviate disgust.
