DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steep slope supporting structure using a mold grid.

[0002]

2. Description of the Related Art As this kind of technology, FR-PS 2
No. 303121 discloses the use of vertical or step-like mold grids. By the way, in this technique, a basket-shaped lattice arranged vertically is used. In addition, these cage-shaped lattices are provided with a bottom wall that extends relatively wide underground and anchors the support structure.

[0003]

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

In view of the above, the present invention is essentially simpler to construct and replant, and in the case of grass replanting, it can be implemented mechanically in a simple manner, and Even when an inclined surface is formed, the present invention provides a steeply inclined surface supporting structure capable of obtaining an inclined surface having a flat surface and an inclination angle of, for example, 60 °.

[0005]

SUMMARY OF THE INVENTION The present invention provides a front wall 4 which is provided with a rod end 8 projecting from its upper end and which is covered with a lining capable of growing, in particular a plant fleece 1.
a and a plurality of mold grids 4 having a bottom wall 4b covered by the reinforcing fleece 3 are connected to the rod ends 8 of the respective mold grids 4.
Are stacked so as to penetrate the substantially horizontal bottom wall 4b of the mold lattice 4 located immediately above and restrain the front wall 4a of the mold lattice located immediately above from the rear, and the reinforcing fleece 3
A steep slope supporting structure which is embedded in the ground in a state of being superposed on the bottom wall 4b on the entire surface of the bottom wall so as to function as a tension member of the mold lattice 4,
The mold lattice 4 is formed by combining a plurality of rods in a lattice shape, and the lining 1 having a growth ability is provided as a series along both the front and back surfaces of the front wall 4a and the upper surface of the bottom wall 4b. After filling the mold grid 4 with the earth and sand until the height is almost the same as the upper end of the earth wall 4a, the part which has been covered on the front surface of the front wall 4a is folded back so as to cover the upper surface of the earth and sand .
The rod end 8 of the front wall 4a occupying the uppermost position is moved rearward.
The present invention relates to a support structure for a steep slope that is bent so as to extend downward .

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

By the way, the essence of the invention is that the growable lining forms the means for clamping the plant layer. And, since this plant layer causes stabilization of the steep slope, the steep slope does not collapse even after the mold grid is corroded.

[0008] The mold grid of the present invention comprises only one bottom wall and one front wall. That is, since there is no top wall, debris can be spilled into the mold grid without interference and then tamped.
This operation can also be mechanized.

The mutual restraint between the upper and lower front walls results in particularly high steep slope stability, especially in the early stages of greening. The more effective application of the present invention will become apparent from the details described below.

In the front wall, the upwardly protruding rod end belonging to the front wall occupying the uppermost position is preferably bent rearward. Further, it is preferable that the laterally adjacent mold lattices overlap with each other via a laterally protruding iron bar end.

In order to moor the upper end of the front wall,
Preferably, an end moor is used, one end of which is attached to at least one of the bars of the front wall and the other end is attached to at least one of the bars of the bottom wall.

[0012] The inclination angle of the front wall can be about 60 °. Further, the distance between the bottom walls adjacent in the vertical direction can be about 0.5 m. Preferably, the plant fleece and the reinforcing fleece overlap each other in the range of the bottom wall.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows two mold grids 4 arranged one above the other.
Is shown. The mold grid 4 has a bottom wall 4b extending horizontally 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 The vertical distance between two adjacent bottom walls 4b reaches, for example, about 0.5 m. In addition, such a mold lattice 4
Are stacked up and down depending on the height of the inclined surface.
Also, these mold grids 4 can be built-in and made of corrosive metal in a cost-effective manner.

The front wall 4a has a plurality of bar ends 8 projecting upward, and these bar ends 8 are connected to at least one of the bars 7 arranged at the lower part of the mold grid 4 immediately above. Bound by The upper and lower front walls 4a thus lean against each other. Further, the front wall 4a is additionally held at its upper end by the end mooring device 2. The end mooring device 2 has one end attached to the reinforcing bar 6 on the front wall 4a and the other end attached to the iron bar 9 on the bottom wall 4b.

Since the iron bars 7, 6 and 9 are particularly protruding at the ends, the laterally colliding mold grids 4 overlap and thus likewise lean against each other in the lateral direction. The protruding end can be made longer as shown by reference numeral 7a in FIG.

The mold lattice 4 is lined with a lining that is flat and can grow. This lining is made of a plant fleece (das V
acquisitionsvlies) 1. In addition, this plant fleece 1 has a reinforcing fleece 3 in the range of the bottom wall 4b.
But this reinforcing fleece 3 is connected to the bottom wall 4b.
And spread in the soil, and the mold lattice 4 is moored to the soil. Thus, the reinforcing fleece 3 functions as a tension member at the bottom of the mold lattice 4, and exhibits high strength when a small tensile force is applied.

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

Next, the method of using the support structure will be described.
First, after the ground is leveled, the first reinforcing fleece 3 is spread on the ground, and the mold grid 4 is arranged on the reinforcing fleece 3. After the protruding rod end 8 is covered with a split tube 5, the plant fleece 1 is spread as shown in FIG. Next, after the end mooring device 2 is attached, the soil 11 is carried into the mold grid 4 and compacted.

Next, when the upper surface of the soil 11 is leveled to prepare a new flatland, the plant fleece is subsequently spread. Thereafter, as shown in FIG. 2, the area indicated by reference numeral 1a of the plant fleece 1 is hit and tightened.

Next, the second mold grid 4 is placed on the second flat ground, and the protruding rod end 8 is restrained behind the lower iron bar of the overhead mold grid. The above operation is repeated until the steep slope reaches the desired height.

In the case of the last mold grid 4 occupying the uppermost position, the projecting rod ends 8 are bent back as shown in FIG. Subsequently, the 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]

Since the present invention has the above configuration,
After arranging the mold grid, the work of inserting and compacting the soil becomes extremely easy, and mechanization becomes possible. In addition, since the mold lattice is not bulky, transportation is easy.
