Description

  TECHNICAL FIELD The present invention relates to a water stop device that is installed in front of a building or a place where it is desired to prevent water from entering when a guerrilla torrential rain or the like occurs and that prevents water from entering a building or the like.

In recent years, record heavy rain has continued, and a large amount of rain has fallen at one time, preventing the drainage system from catching up and causing much damage by water entering the building.
During these guerrilla downpours, sandbags have traditionally been used to prevent water from entering the building. The sandbags were filled with sand and dirt, so working with women was very difficult and required a lot of labor to carry heavy. Also, removing the sandbags after having absorbed the water was even more heavy and labor intensive. Furthermore, in the city center, it was difficult to procure soil and store sandbags.

  For this reason, there is a demand for a water stop device that is lightweight and easy to install. For example, Patent Literature 1 discloses a water stopping device that prevents water from entering from one side to the other, and includes a bottom plate provided with a water stopping member on a back surface, and a rising plate rising from a rear end of the bottom plate. It is L-shaped, and has a configuration in which at least one end of the left and right ends of the water stop device has a connecting portion for connecting the water stop device and the water stop device to the left and right. Because the structure is very simple and lightweight, even elderly people and women with poor physical strength can easily carry the water stop device from the storage location and quickly stop the water at the site where it is necessary to stop water. There has been proposed an invention in which a water-impervious wall can be constructed by connecting each other.

  Further, for example, Patent Document 2 discloses a panel sandbag for preventing inundation into a certain area in a flood or the like, a horizontal part extending in a direction opposite to the certain area, and an end of the horizontal part on a certain area side. A horizontal portion and a vertical portion are made of a waterproof material and have a hollow portion communicating with the extending direction, and the hollow portion extends in a direction in which the horizontal portion extends. There has been proposed an invention in which a side end communicates with a vertical end of the vertical portion in the extending direction.
