BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optimal slope protection block which is mainly used for protecting slopes on river banks from erosion by running water.

[0002]

2. Description of the Related Art Conventionally, this kind of slope protection block is roughly classified into a so-called assembly type in which a plurality of frame members are assembled and formed on site and a finished product. The latter includes a so-called plate-shaped body whose entire surface is covered with a concrete plate and a so-called frame-shaped body having a hollow portion inside, and the plate-shaped body has a sloped surface. The construction of the frame-shaped body is the same as that of the above-mentioned assembled frame-shaped body.

However, in any of the above-mentioned conventional ones, there is a risk that the joint portion between the blocks after laying is conspicuous and the entire landscape is spoiled. In particular, when the slope to be laid is curved, the joint between the blocks will correspond to this curve, so the joint width of this joint will be different at the top and bottom, and the poor scenery as described above. Has the drawback that it appears more prominently. Furthermore, if this kind of slope protection block is laid on the entire slope, workers and ordinary people who maintain it will walk on the block,
Since the block has unevenness and is slippery and dangerous, it is necessary to separately provide a stair at a desired position, which causes a problem of high cost.

[0004]

The present invention has been made to solve the above-mentioned conventional problems, and the left and right sides, which are the joint portions of the rectangular frame, are formed one step higher than the upper and lower sides. The purpose of the present invention is to provide a product which is formed low and is connected through a connecting member having the same height as the upper and lower sides so that the joint is inconspicuous and the upper part of the connecting member can be used as a sidewalk surface. The gist of the invention is a rectangular frame body formed of both upper and lower sides and left and right lower sides which are one step lower than that, and a connecting member having the same height as the upper and lower sides and the same length as the left and right sides. The slope protection block is characterized in that it is integrated with the ground by concrete cast into the internal space of the rectangular frame body to the same height as the upper surfaces of the left and right sides.
