The river flows through the lowest part of the valley. However, when the amount of precipitation is high, the water level rises and becomes considerably wide and flows out. Especially, in the plain part, flooding occurs in a wider range.

Therefore, the inhabitants living along the rivers lived by solving these problems by limiting the width of the river by building the bank.

On the other hand, the conventional river water hammock is constructed by installing a block of water on the slope of the river bank, and the hydroelectric power, the positive pressure and the negative pressure are generated, which greatly affects the stability of the bank and is easily damaged by the flowing water.

Recently, in order to solve such a problem, various techniques have been proposed. Among them, in the case of Registration No. 10-0743543, in order to prevent loss of the river bank, a waterproofing block A plurality of quadrangular revetment blocks connected to each other on an inclined surface are penetrated by a flexible zinc wire to strengthen the fastening force and are fixed by upper and lower concrete assemblies. However, in the case of the above-mentioned technique, auxiliary structures, And there is a problem that it takes a long time and there is a problem that it is difficult to replace when the revetment block is removed.

In addition, although a method of filling a soil filler in geosynthetic fiber on the land as shown in Patent Registration No. 10-1268681 to make a soil pouch in the form of a breakwater and putting it in water has been proposed, There is a possibility of levee leaking, and it is composed only of gravel and soil so that aesthetics are bad and ecological environment can not be created.
