[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a support structure for a steep slope using a molded lattice.

0002

[Prior Art] As this type of technology, FR-PS
No. 2,303,121, the use of vertical or stepped gratings is known. By the way, this technology uses basket-shaped grids arranged above and below. These basket-shaped grids are also provided with a bottom wall that extends relatively widely into the ground and anchors the support structure.

0003

SUMMARY OF THE INVENTION The cage-shaped grid is not only bulky, but also requires a relatively large amount of energy to fill and compact the soil after installation.

[0004] In view of the above-mentioned points, the present invention is essentially simpler to construct and green, and in the case of greening with grass, can be carried out in a simple manner and mechanically. The present invention provides a support structure for a steep slope, which can have a flat surface and have an inclination angle of 60°, for example, even when creating a slope.

[0005]

SUMMARY OF THE INVENTION The present invention provides a support structure for a steep slope comprising a plurality of mold grids arranged one above the other, in which the mold grids are provided with a lining capable of growing at least in the area of their front wall. It has a bottom wall covered with vegetable fleece and extending substantially horizontally with a plurality of horizontally extending reinforcing fleeces, the front wall having an upwardly projecting rod end, except for the front wall in the uppermost position. A support structure for a steep slope, characterized in that the front wall directly above the lattice is restrained from behind, the reinforcing fleece is overlapped in the area of the bottom wall, is buried in the ground, and acts as a tensile member for the type lattice. This is related to.

That is, in this invention, the reinforcing fleece is buried in the ground together with the statically necessary reinforcing portion. Therefore, the bottom wall of the mold grid can be shortened and the mold grid can be easily transported.

The essence of the invention, however, is that the growable lining forms a clamping means for the plant layer. Since this plant layer stabilizes the steep slope, the steep slope will not collapse even after the mold lattice corrodes.

The above-mentioned type grid of the invention consists of only one bottom wall and one front wall. That is, since there is no top wall, rubble can be introduced into the mold grid and then tamped without hindrance. This work can also be mechanized.

The mutual restraint between the upper and lower front walls results in particularly high stability of steep slopes, especially in the early stages of greening. Further, more effective application of the present invention will become clear from the detailed description below.

[0010]In the above-mentioned front wall, it is preferable that the upwardly projecting rod end belonging to the front wall occupying the uppermost position is bent rearward. Further, it is preferable that the horizontally adjacent mold grids overlap each other via the ends of the iron rods that protrude laterally.

[0011] Also, in order to moor the upper end of the front wall,
Preferably, an end anchor is used, one end of which is attached to at least one of the iron bars of the front wall, and the other end of which is attached to at least one of the iron bars of the bottom wall.

[0012] Also, the angle of inclination of the front wall can be about 60°. Further, the distance between the vertically adjacent bottom walls can be about 0.5 m. Further, it is preferable that the vegetable fleece and the reinforcing fleece overlap each other in the region of the bottom wall.

[0013]

Embodiments Examples of the present invention will be described below with reference to FIGS. 1 to 3. Figure 1 shows two mold grids 4 arranged above and below.
shows. The mold grid 4 has a horizontally extending bottom wall 4b and a front wall 4a inclined with respect to the bottom wall 4b.

The inclination of the front wall 4a with respect to the bottom wall 4b defines the inclination of the slope, which in particular is approximately 60°.
reach. Further, the vertical distance between two adjacent bottom walls 4b reaches approximately 0.5 m, for example. Furthermore, such a type grid 4
However, depending on the height of the slope, multiple pieces can be stacked one above the other. These mold grids 4 are also built-in and can be made of corroding metal in a cost-effective manner.

The front wall 4a has a plurality of rod ends 8 projecting upward, and these rod ends 8 are connected to at least one of the rods 7 disposed at the lower part of the mold lattice 4 directly above. be restrained in one direction. The upper and lower front walls 4a thus lean against each other. Furthermore, this front wall 4a is additionally held at its upper end by an end anchoring device 2. The end mooring device 2 is attached at one end to the reinforcing rod 6 on the front wall 4a and at the other end to the iron bar 9 on the bottom wall 4b.

The iron rods 7, 6 and 9 are particularly projecting at their ends, so that the laterally abutting mold grids 4 overlap and thus also lean against each other laterally. Note that the projecting end can be made longer, as shown by reference numeral 7a in FIG.

The mold grid 4 is lined on the inside with a flat and growable lining. This lining is made of vegetable fleece (das
Vegetations vlies) 1. Note that this vegetable fleece 1 overlaps with the reinforcing fleece 3 in the range of the bottom wall 4b;
b into the soil, mooring the mold grid 4 to the soil. The reinforcing fleece 3 thus acts as a tensile member at the bottom of the mold grid 4 and exhibits high strength when subjected to small tensile forces.

[0018] The reinforcing fleece 3 must spread widely in the soil in order to secure the necessary tensile force, but the extent to which it spreads depends on the height of the structure, the ground condition, the overall stability of the soil, etc. Dependent. And it can be estimated immediately by a skilled person.

Next, how to use the above support structure will be described.
After the ground has first been leveled, a first reinforcing fleece 3 is spread on this ground, and a pattern grid 4 is placed on this reinforcing fleece 3. Then, after the protruding rod end 8 is covered with the slotted tube 5, the vegetable fleece 1 is unfolded as shown in FIG. After the end anchorage 2 is then installed, the soil 11 is brought into the mold lattice 4 and compacted.

[0020] Next, after the upper surface of the soil 11 is leveled to prepare a new flat area, the vegetable fleece is subsequently spread out. Thereafter, as shown in FIG. 2, the area indicated by reference numeral 1a of the vegetable fleece 1 is beaten and tightened.

Next, the second type grid 4 is placed on the second flat surface, and the protruding bar ends 8 are restrained behind the lower iron bars of the directly overhead type grid. The above operation is repeated until the steep slope reaches the desired height.

In the case of the last mold grate 4 occupying the uppermost position, the projecting rod ends 8 are bent back as shown in FIG. Following this, soil 12 is carried into the tray-shaped portion. A particularly natural surface is thus obtained at the upper edge of the soil 12, on which roads or tracks can be provided.

[0023]

[Effects of the Invention] Since the present invention has the above-mentioned configuration,
After placing the pattern grid, the work of filling and compacting the soil becomes extremely easy and can be mechanized. Moreover, since the molded grid is not bulky, it is easy to transport.
