Description

FLOOD DEFENDE WALL AND INSTALLATION METHOD OF THIS}

The present invention relates to a flood barrier and a method for installing the same, and more specifically, is installed at the boundary area between the ground and the river to partition the ground and the river, and even if the flow rate of the river is increased due to the heavy rain or the like, Flood barriers to prevent flooding to the ground and to install them.

Generally, all rivers, rivers, etc. are provided with levees. The dike allows rivers or rivers to flow along certain paths and prevents flooding by preventing water from overflowing the dike.

Today, river maintenance projects are being actively carried out to build high banks instead of straightening the waterways and reducing river widths for safe and efficient flood control. The river maintenance project has the advantages of efficiently managing and utilizing water, preventing floods from flooding of rivers, and maintaining clean and beautiful waterfront environment for tourism or recreational facilities.

The most important thing for river maintenance is to maintain the banks. Instead of narrowing the width of the river before, because the dike must be raised and firmly stacked. At this time, considering the precipitation of the process of raising the embankment, even if a heavy rain occurs, it is stacked enough to withstand. However, in recent years, due to rapid climate change, the amount of precipitation or heavy rainfall is increasing more than in the past. Therefore, it is difficult to ensure the safety of the embankment in case of the heavy rain or heavy rain due to the abnormal weather in the conventional embankment installed according to the past standard.

Nevertheless, there is a limit to simply raising the height of the conventional embankment. Because if the height of the dike increases, the width must be increased in proportion to the height of the dike, so that the land around the river or the river must be accommodated. In this case, not only the cost of the maintenance work increases, but the height of the dike is too high. This is because it is less accessible to people and hurts the surrounding landscape. Therefore, in recent years, efforts have been made to prevent flooding of rivers on the banks due to heavy rain by installing flood barriers on the banks of the related art.
