Description

(Eco-friendly Slope Protection Device for River Bend)

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a slope protection device for an environmentally friendly river bend, and more particularly, to a slope protection device for an environmentally friendly river bend, which can be freely installed along a curved portion of a river slope, .

Generally, concrete slabs are installed on river slopes to prevent soil loss, but these concrete blocks have no room for vegetation to grow, which makes it difficult for artificial vegetation or natural vegetation to harm natural aesthetics and adversely affect natural ecosystems. .

If the grass does not grow on the concrete block, insects do not live in the river, and the birds that live on the insects are reduced and the ecosystem is exchanged.

These concrete blocks are required to maintain their position by their own weight, but have no binding force between them. Therefore, there is a problem that rainwater is continuously introduced into the gap between the concrete blocks in the rainy season and the soil is lost or the concrete block is lost.

Japanese Laid-Open Patent Application No. 20-0439588 (published on Mar. 21, 2008) proposed a conventional technique in which a cross-shaped clevis connector and a pin are used to connect rectangular plates in a checkerboard shape.

However, in the related art, there is a problem that when one of the clevis connector and the pin is broken in the middle, all the remaining lower parts are separated and lost.
