Description

[Detailed Description of the Invention] The present invention relates to a slope protection frame for preventing the slope from being scoured.

Conventionally, as this kind of slope protection frame,
As described in Japanese Patent Application Laid-Open No. 52-75813, etc., it is known that a wire mesh is adjusted between lattice frames laid on a slope.

However, in such conventional slope protection frames, one piece of wire mesh is stretched between each lattice road, so depending on the area, it may take time to transport the wire mesh, or it may be difficult to transport the wire mesh onto a slope with poor footing. It is often inconvenient, and
If the wire mesh is wide, when it is stretched over a slope, the strength of the middle portion will inevitably be weakened, and that portion will tend to bulge upward.

The object of the present invention is to facilitate the transportation and tensioning work of the wire mesh, and to reliably prevent the wire mesh from floating in the middle position of the grid.

In order to achieve the above object, the slope protection frame of the present invention consists of a plurality of concrete frames arranged in series to form a lattice-like frame body with spaces between the concrete frames, and the upper surface of each of the above spaces is A protective wire mesh consisting of a plurality of unit mesh bodies is provided, and at least an upper edge of each unit mesh body is provided with a downwardly directed bent part, and the bent part is embedded in the slope. It is characterized by a resistance plate attached to the lower end.

Hereinafter, embodiments of the present invention will be explained in detail based on the drawings.As shown in Figures 1 and 2, this slope protection frame is installed on a slope and protects the surface layer of the slope. The frame body 1 includes a frame body 1 that prevents slipping, and the frame body 1 has a large number of concrete frames 2 arranged in a grid pattern, with spaces 3 between the concrete frames 2.
By installing this frame body 1 on a slope, the slope is divided into small sections to prevent the surface layer of the slope from slipping.

The frame body 1 has reinforcing materials 4 such as iron rods or iron pipes from both ends.
The ends of a plurality of concrete frames 2 with projecting edges are successively butted together radially, and hooks are used to lock a protective wire mesh 6, etc., which will be described later, to the concrete 5 that is poured into the butted areas to fix them, as necessary. The base of the locking member 7 having a shape is embedded therein.

The protective wire mesh 6 stretched in the space 3 between the concrete frames 2 is intended to prevent the divided slope from being directly immersed in water when the frame body 1 is installed on the slope. The protective wire mesh 6 includes a plurality of unit mesh bodies 8, 8 . . . ., each unit net body is connected by an appropriate connector 9, and the four corners of the protective wire net 6 are locked to the upper locking members 7, so that the frame body 1 is stretched. Each unit has a mesh body 8, 8.・
There is a bent part 8 bent downward on the periphery of...
A is formed, each bent portion 8a is embedded in the slope, and a resistance plate 10 made of an iron plate, wire mesh, etc. is connected to the lower end of the bent portion 8a in parallel with the slope.

The purpose of embedding the bent portion 8a is to create resistance due to earth pressure in the bent portion to prevent the unit netting from floating up. Because of this, the upper side of the slope tends to float, and once the upper edge side floats, the entire surface tends to peel off from the slope surface, so it is necessary to suppress the floating of the upper edge side in particular. As is clear from FIG. 2, the bent portion 8a may not be provided on the side edge side or the lower edge side where it is difficult to bend, but may be provided only on the upper edge.

Further, in the illustrated embodiment, the unit mesh body 8 is formed of a welded wire mesh, but it can also be formed of a crimp wire mesh. The interval can be set arbitrarily.

To install the protective frame having the above structure on a slope, first install a plurality of concrete frames 2 on the slope individually, then insert the locking members 7 into the butt portions of the concrete frames 2 and attach the concrete 5.
By filling the concrete frame, the concrete frame is fixed together in a lattice shape, and the space 3 in the frame body 1 is filled with soil or stones, and the turf or seeds are sown. The protective wire mesh 6 is placed on top, and its bent portion 8a is embedded in the slope, and adjacent unit mesh bodies 8 are connected by connectors 9, and the four corners of the protective wire mesh 6 are connected to the locking members 7.

According to the slope protection frame configured in this way, each subdivision of the surface layer of the slope is surrounded by the concrete frame 2 and covered with the protective wire mesh 6, so that the earth and sand on the slope will not slide down. In addition, even in the event of rain, the rainwater flowing down within the above-mentioned subdivision is dispersed and slowed down by the protective wire mesh 6, so that it does not become a concentrated high-speed flow. Therefore, even if an upward force is applied to the unit net body 8, the unit net body 8 will not float due to the resistance of the bent portion 8a.
This prevents damage and maintains the installed state extremely firmly.

In this case, as shown by the chain line in FIG. 2, a resistance plate 10 made of a steel plate, wire mesh, etc. is connected to the lower end of the bent portion 8a in parallel with the slope, so that the drag force due to the bent portion 8a is reduced. Further increase.

Furthermore, since the bent portion 8a has the function of supporting the earth and sand above it and suppressing its flow down, the movement and outflow of the earth and sand within the subdivision is more reliably prevented.

Further, the frame body 1 may be arranged in a rectangular lattice shape as shown in FIG. It is sufficient to bend the two adjacent upper sides of the body 8 downward.

As described above, according to the present invention, since the protective wire mesh installed in the space between the concrete frames is composed of a plurality of unit mesh bodies, it can be easily transported, especially to a construction site with poor footing. In addition, each unit net has a bent part at least on the upper edge, and the bent part is buried in the slope and a resistance plate is attached to the lower end of the bent part. As a result, the resistance of the bent portions can reliably prevent the unit mesh from peeling off due to floating, and when the protective wire mesh is formed of a single mesh, the central portion of the Because the strength is weak, this part tends to bulge upwards, and therefore it is necessary to restrain the protective wire mesh with reinforcing ropes, etc. However, in the case of the present invention, the floating of the unit mesh body is suppressed by the folded part, and the protective wire mesh This prevents the central part from bulging out, so there is no need to separately install reinforcing ropes, etc. Furthermore, since the bent part also acts to support the earth and sand located above it, it prevents the movement and outflow of earth and sand. can be suppressed even more effectively.
