Benefits of technology

[0006]The primary objective of the present invention is to provide a sandbag that is decomposable and contains water-absorbing polymers to absorb water and expand rapidly.

Problems solved by technology

The environment in the world has been destroyed and the weather is abnormal, so many natural disasters occur frequently in the world, such as hurricane and cloudburst.
At a result, hurricane and cloudburst will lead to a flood or an inundation by the sea.
When water floods into houses, inhabitants will be in trouble and lose their property.
However, the traditional sandbag has a large dimension and a heavy weight, so it is hard to be moved and inconvenient to be stored.
In addition, the sandbag can not be decomposed and will create a polluted problem.

Abstract

A sandbag has a bag, multiple adhesives and at least two filler layers. The bag is made of a water-permeable material and has an inner surface. The adhesives are mounted in the bag. The filler layers have water-absorbing polymers nebulized by a low pressure and sprayed on the adhesives evenly. The filler layers adhesive on the adhesives, so the filler layers will not move and can expand evenly.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]The present invention relates to a sandbag, and more particularly to a sandbag that is decomposable and contains water-absorbing polymers to absorb water and expand rapidly.[0003]2. Description of the Related Art[0004]The environment in the world has been destroyed and the weather is abnormal, so many natural disasters occur frequently in the world, such as hurricane and cloudburst. At a result, hurricane and cloudburst will lead to a flood or an inundation by the sea. When water floods into houses, inhabitants will be in trouble and lose their property. Thus, the inhabitants will place sandbags as a barrier to prevent or decrease water to flood into the houses.[0005]A conventional sandbag has a bag such as a burlap bag filled with sand or soil. When used, multiple sandbags are stacked to be a barrier to keep water from entering the houses. However, the traditional sandbag has a large dimension and a heavy weight, so it is ...
