用いて法面に取り付けるものである。However, in the above-mentioned conventional staircase vegetation method, a staircase-shaped greening structure which is self-supporting and previously formed by bending it into a plurality of staircases is used as an anchor. It is attached to the slope by using steel plates and concrete nails.

かった。Therefore, there are various irregularities on the surface,
It was difficult to attach a stair-like green structure on the slope where the slope changes, and it was difficult to fix it along the slope because it had to be bent and grounded.

Sequentially connected in a foldable manner so as to present a staircase when placed on the slope in the state, the soil retaining sheet is attached to the wire mesh frame to form pockets, and A heat insulating sheet is hung on the inner surface of the wire mesh frame. Then, the lower connecting portion of each tread wire mesh frame and riser wire mesh frame of the slope greening structure is sequentially fixed to the slope and fixed in a step shape, and then,
The soil retaining sheet attached to the wire mesh frame is filled with a vegetation base material for growing plants.

呈するので施工しやすいという点で優れている。As described above, by adjusting the deployment angle between the tread wire mesh frame 2 and the riser wire mesh frame 3 in accordance with the slope to be constructed, it can be used regardless of the slope of the slope. In this case, a slope greening structure that does not regulate the expansion angle between the tread wire mesh frame 2 and the riser wire mesh frame 3 is used, and the slope surface is at a desired expansion angle according to the slope angle of the slope surface during construction. It is possible to use a method of fixing the angle of deployment and a method of preparing a plurality of types with different deployment angles in advance and selecting and using an object according to the slope from among them. Since it is not necessary to prepare a plurality of different types, it has the advantage of being economically superior and being able to deal with cases where the slope of the slope changes greatly continuously. The latter is excellent in that it is easy to construct because the tread wire mesh frame 2 and the riser wire mesh frame 3 form a desired angle only by unfolding at the time of construction.

ト化を図ることができる。As described above, according to the present invention, since the step surface wire mesh frame and the riser surface wire mesh frame are formed in a step shape, the slope surface like a slope structure including three wire mesh frames. It does not require a wire mesh frame on the side, and can reduce costs in terms of products and construction.

The cost is low, and it is convenient for storage and transportation.In particular, the tread wire mesh frame and the riser wire mesh frame are foldably connected in sequence so as to have a step shape at the vertical edges. Therefore, even if there are various irregularities on the surface of the mounting slope or the slope changes when mounting on site, it can be easily fixed along the slope.

流失を有効に防止することができる。Further, since the soil retaining sheet is attached to the upper edge of the kicking surface wire netting frame so as to form a pocket, the introduced vegetation base material is securely held and the inside surface of the kicking wire wire netting frame is held. Since the heat insulating sheet is hung on the floor, it is possible to protect vegetation from freezing in the winter, for example, and to make the wire mesh of the tread wire mesh frame rough and the wire mesh of the kicking surface wire mesh frame. By making it fine, it is possible to facilitate the feeding of the vegetation base material after it is attached to the slope, and it is possible to effectively prevent the poured vegetation base material from being washed away.

Reinforcing rods and other reinforcing materials are laid at the connection with the upper edge of the wire mesh frame, fixed on the slopes with anchors, and then hardened by spraying a hardening material such as concrete for reinforcement. be able to.
