Description

The present invention relates to a levee method shoulder block.

Breaking of embankments, so-called embankments, is caused by several patterns. For example, a pattern in which the soil on the surface of the front law is scraped off and causes a breach due to a violent flow or waves of the river, a pattern in which a crack is formed on the slope of the levee and it spreads and causes a breach, a pattern of a river The pattern that the water level rises and the water pressure causes the river water to permeate the embankment and the water blows out from the backside side to cause the embankment. There are patterns that cause it.

Depending on each pattern, it is necessary to take different measures to prevent levee breakage. Furthermore, as disclosed in Patent Document 1, many coastal levees have been destroyed by the tsunami caused by the Great East Japan Earthquake in 2011, and countermeasures are urgently needed.

On the other hand, river embankments have also been breached due to flooding caused by local heavy rainfall in recent years, and it is necessary to take measures against this.

In the past, the basic measure for flooding was to raise the height of the embankment to prevent flooding itself, and for that purpose, it was necessary to increase the width of the embankment. Such measures cost enormous costs, and in the case of river embankments, it is often necessary to extend the embankments to private land that extends behind the embankments, and such measures are actually implemented. There was a problem that it could not be done. Therefore, it is necessary to take measures to prevent the levee from breaking when flooding occurs.

For example, it is common practice to cover the top of a dike with asphalt to make it a road, but at present, flooding is not considered. In other words, even if a road is installed on the top surface, the law shoulder, which is the boundary between the top surface and the law, is not protected. It may lead to a bank breakage. Therefore, in order to prevent the shoulder from being scoured in this way, it is conceivable to cover the shoulder with a concrete block from the top edge to the upper part of the slope to protect the shoulder.
