Description

There is an application for exception of loss of novelty

The present invention relates to a water sac used for preventing water from overflowing from an embankment.

Traditionally, sandbags have been widely used for emergency measures in the event of floods and for civil engineering work in general.

However, since sandbags are civil engineering materials in which earth and sand are packed in a cloth bag, not only does the work itself require a great deal of labor, but the weight of each sandbag is approximately 20 kg in a general size, and it is transported and laminated. The work was also a heavy burden on the workers.

In order to eliminate such a work load, a water bag filled with water instead of earth and sand has been developed inside the bag body, and various patent applications have been filed.

For example, Patent Document 1 relates to a water sac made of a waterproof sheet such as a tarpaulin and in which a large number of trapezoidal steel wires are arranged at regular intervals outside the body of the water sac body having a water injection port and a discharge port. The invention is described.

Further, Patent Document 2 includes a sealed space for filling the dam forming material with water, a water injection port for injecting water into the sealed space, and a drainage port from the sealed space, and is adjacent to both ends thereof. Describes an invention relating to a water sac provided with a connecting fin for connecting the water sac to each other.
