The present invention relates to an eco-friendly slope recording method for preventing erosion, precipitation, and landslides, and a slope recording structure using the same. In detail, it relates to an environmentally friendly slope greening method and greening structure for protection and greening of slopes damaged by sedimentation, erosion slopes, forest fires, embankment slopes, cut slopes, existing shoreline block slopes, and rock incision slopes caused by landslides, etc. .

Slopes that have been settled, eroded by landslides, damaged by forest fires, etc., slopes exposed in the process of expanding roads, and slopes exposed due to the loss of rivers are at risk of collapsing if left unattended. The conventional slope protection method used a method of installing a concrete structure on the slope. However, the conventional method has a problem that does not match with the surrounding natural environment, and vegetation is installed together to solve the problem. However, the installed concrete has difficulty in vegetation smoothly by restricting the growth of vegetation.

To solve this, a slope recording method without using concrete has been attempted. The slope greening method includes a greening method using a vegetation mat, a greening method using a vegetation spray, and a greening method using a vegetation block. The slope greening method has the advantage of being able to be green on a slope that does not have any growth environment conditions, such as soil or rock of sandy soil. In particular, the greening method using the vegetation mat is a method mainly applied to slopes of coastal areas where there is sedimentation or erosion, dangerous areas of landslides, and mountainous areas weakened by forest fires, etc. It has many advantages and is used a lot. However, vegetation mats had the disadvantages of being inconvenient to the site and vulnerable to strong winds and rainfall.

In Korean Patent Publication No. 10-2010-0100509, in order to solve the problem of the vegetation mat, a log mat and a vegetation mat are produced as a set, then rolled into a roll form, transported to the site, and installed on a slope to facilitate transport and construction. A slope recording method for securing a stable slope has been disclosed. However, the slope recording method is a method of overlapping the log mat and the vegetation mat to install a plurality of log mats and vegetation mats across the left and right sides of the slope. Therefore, when some slopes descend due to gravity or rainfall, the connection part of the log mat is separated or struck, and repair is often required.

The patent documents and references mentioned in this specification are incorporated herein by reference to the same extent that each document is individually and clearly specified by reference.
