である。2. Description of the Related Art Various protection methods for slopes have been proposed in the past, but in recent years, in addition to the stability of the slope itself, greening has been emphasized from the viewpoint of landscape. One of the construction methods in consideration of such greening is to build a grid-shaped legal frame made of cast-in-place concrete on the slope, and spray plant seeds etc. inside the lattice frame.
Alternatively, a method of vegetation is known by installing a vegetation mat. Also, instead of cast-in-place concrete,
A method of constructing a grid-shaped method frame using a large number of cross-shaped precast concrete blocks is also known. This method also aims at greening by applying vegetation inside the lattice frame.

ない。The legal frame constructed by the above-mentioned construction method has a lattice-like pattern on the slope, and therefore, in combination with the vegetation inside the lattice frame, it can be said that it has a beautiful appearance in some aspects. However, on the other hand, the concrete structure is exposed on the slope, impairing the aesthetics. Further, in the case of cast-in-place concrete, not only a great deal of labor is required for construction on the slope, but also the construction period is long. In this respect, in the case of a precast concrete block, it is sufficient to bring in the factory-produced one to the site and install it.
Although there is no such difficulty, it is heavy and not easy to carry in.

Securely held in. That is, if there is no partition plate, the sandbag 33 or the soil inside may be biased toward the lower side of the slope due to the gradient in the long term, and a large void may occur at the upper side to expose the root of the tree. By partitioning the plant into a plurality of planting rooms, such a phenomenon can be reliably prevented.
