BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope protection structure for preventing collapse of an inclined soil surface.

[0002]

[Prior Art and Problems to be Solved by the Invention]
In order to prevent collapse of steep slopes and cut slopes, a method of constructing precast concrete members and steel method frame members, or a method of assembling formwork on site and placing concrete on it. The method of forming a legal framework is being implemented. However, these conventional construction methods require a high level of skill and a lot of labor for assembling members, assembling a formwork, and placing concrete, and also require a long construction period and a large amount of cost. Also, because the construction is simple and the construction cost is low,
There is also a method of spraying mortar on the entire slope, but this method has a weak effect of pressing the slope completely because the strength of the mortar is weak, and it also separates the slope and the sprayed mortar. Therefore, it requires frequent repairs.
There were many problems.

The present invention solves the above-mentioned drawbacks of the prior art and does not require the assembly of a heavy frame member or the formation of a concrete frame by a formwork, and a simple mortar spraying means. The present invention intends to provide a slope protection structure which is strong in strength, has a good slope protection effect, and can be constructed at low cost.

[0004]

The structure of the present invention for achieving the above object will be described with reference to the drawings corresponding to the embodiments. A large number of wire mesh plates 1 formed by bending are formed by arranging the projecting ridges 2 and 2 in parallel in the transverse direction of the slope and at the same time overlapping each edge in the vertical direction of the slope. Being laid,
It is characterized in that it is embedded in the sprayed product of the mortar 5 and that the bulging strips 6 and 6 extending in the transverse direction of the slope are formed in the projecting strip portions 2 and 2.

[0005]

In the present invention, a large number of bulging strips 6 of mortar 5 having the wire netting plate 1 as a reinforcing member are provided on the slope at intervals in the vertical direction, and mortars 5 are provided between them. Will be formed, and the slope will be strongly protected by the mortar 5 adhesion layer.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side sectional view showing an embodiment of the present invention, and FIGS. 2 to 3 are side views showing a wire mesh plate 1 used in the embodiment, respectively.

As shown in FIG. 2, the wire mesh plate 1 is a rectangular wire mesh plate of a fixed length, one end of which is bent along the transverse direction over its entire length, and a projection of a required width is provided on the upper surface side of the wire mesh. It has a structure in which the strip portion 2 is provided in a protruding manner. In this embodiment, the wire mesh plate 1 has an end portion, for example, an upper end portion, which is bent several times to form a protruding strip portion 2 having a zigzag cross section.

A large number of the wire mesh plates 1 shown in FIG. 1 are laid side by side on the slope. At that time, the protrusions 2 and 2 are arranged so as to be continuous in the transverse direction of the slope, and the wire mesh plates 1 and 1 adjacent to each other in the longitudinal direction of the slope have their end portions mutually. Polymerize and arrange. As a result, on the upper surface of the wire mesh plate which is flat on the slope, a large number of a series of protrusions 2 and 2 which cross the slope are longitudinally spaced. And each wire mesh plate 1,
1 is fixed to the slope ground 3 by an anchor material 4 as appropriate.

The formation of the protrusions 2 on the wire mesh plate 1 is not limited to the above-mentioned embodiment. For example, as shown in FIG. 3, the protrusions are formed by bending the upper end of the wire mesh plate 2 into a triangular cross section. It may be 2. Further, as shown in FIG. 4, both upper and lower end portions of the wire netting plate 1 may be bent obliquely toward the upper surface side over a required vertical length to form a protruding strip portion 2.

Next, a mortar 5 such as mortar or concrete is sprayed onto the wire mesh plates 1 and 1 laid as described above to adhere to the slope. in this case,
The portion with the protruding strips 2 and 2 is also embedded in the sprayed mortar 5. Therefore, the portion where the protruding ridges 2 and 2 are present is bulged, and the bulged ridge body 6 extending in the horizontal direction is formed. In this way, the thickness of the mortar 5 on the slope with the wire mesh plate 1 and the protruding strips 2 as the reinforcement is
A large number of bulging strips 6 extending in the horizontal direction are formed at intervals in the vertical direction.

When the wire mesh plate 1 shown in FIG. 4 is used,
As shown in FIG. 2, the wire mesh plates 1 and 1 in the upper and lower positions are connected by superposing the ends of the projections 2 and 2 to each other, and are bonded to each other through the anchor material 4 to the overlapped portion and the slope ground Fix it.

[0012]

As described above, according to the slope protection method of the present invention, the wire mesh plate having the protrusions formed by bending on the upper surface is laid on the slope, and the mortar is blown from the slope. Since the mortar is attached to the entire slope and a bulging strip extending in the horizontal direction is formed on the protruding portion, the slope is laid with a wire mesh plate and the mortar from above is sloped. The protective layer can be installed by the extremely simple operation of spraying, and a large number of bulging strips can be formed on the protective layer by spraying mortars. Since the board is interposed, it is as strong as the frame material formed by using the conventional precast concrete frame material and formwork, has a high slope protection effect, and is excellent in workability and economy. Etc., and has many advantages.
