[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an optimal slope protection block which is mainly used to protect slopes on a riverbank from erosion due to running water.

[0002]

[Prior 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 part inside, and the plate-shaped body has a sloped surface. The frame-shaped body is the same as the prefabricated frame-shaped body, but the filling work is completed by inserting filling stones in the inner hollow part.

[Problems to be solved by the device]

 However, in any of the above-mentioned conventional ones, the joint between the block and the block after laying is conspicuous, and there is a risk of spoiling the overall landscape. In particular, when the slope to be laid is curved, the joint between blocks will correspond to this curve, so the joint width of this joint will be different at the top and bottom, and the landscape as described above will be different. There is a drawback that the badness becomes more prominent. 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, but there is unevenness on the block and it is slippery and dangerous. Therefore, it is necessary to provide a separate stair at a desired location, which causes a problem that the cost becomes high.

[0004]

[Means for solving problems]

 The present invention was made in order to solve the above-mentioned conventional problems, in which both the left and right sides, which are the joints of the rectangular frame, are formed one step lower and the upper and lower sides are one step higher than this. The purpose of the present invention is to provide one that can be used as a sidewalk surface above the connecting members by making the joints inconspicuous by connecting them via connecting members of the same height. When connecting a rectangular frame formed of both upper and lower sides and lower left and right sides to the left and right sides through a connecting member having the same height as the upper and lower sides and the same length as the left and right sides. In particular, the slope protection block is characterized in that it is constructed so as to be integrated with the ground by concrete cast in the inner space of the rectangular frame body to the same height as the upper surfaces of the left and right sides.
