DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the formation of a road slope,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope frame component that can securely grow and grow plants and trees on slopes that have been leveled in order to control mountain landslides, landslides, and repair excavations.

[0002]

2. Description of the Related Art In order to plant vegetation on a leveled slope, it is necessary to fix the ground, especially the topsoil. Therefore, conventionally, a method has been practiced in which a frame is installed by assembling logs in a square shape on a slope, and growing plants and the like on the soil in the frame. In addition, a large number of frames composed of long plates in a square shape are connected to each other, laid on the slope, fixed to the ground via anchor piles, and soil is grown in each frame to grow herbs etc. Wooden slope frames are used. As a similar technique, Japanese Patent Application Laid-Open
Japanese Patent No. 17668 discloses a shape in which a frame is formed by surrounding a square with a wooden frame material of processed bare skin or natural tree skin without preservative treatment and having a space in the frame, and the frame material has a connection hole for interconnection. Equipped with an insertion hole for a locking member to be cast on the ground,
A sloping protection frame having a structure in which the frame material located below the sloping ground has a height of about 90 m or more and constitutes a levee for blocking rainwater in a state of being laid on the sloping slope, is disclosed. I have. In addition, a slope frame made of concrete or synthetic resin is also used.

[0003]

Among the above-mentioned prior arts, the method using a frame assembled with logs has a drawback that it takes a lot of days to perform log assembly work on site, and the strength of the frame varies. There is a disadvantage that. Next, the wooden slope frame lacks strength due to the structure where the plate is joined with nails, and because it is easily distorted, a gap is formed with the slope, preventing topsoil from flowing out with rainwater There is a drawback that fixation of plants and the like is impaired without being able to do so. Also, Japanese Patent Application Laid-Open
The slope protection frame disclosed in Japanese Patent No. 0-17668 has the same drawbacks as described above. Further, since the frame materials of the adjacent protection frames are connected to each other with bolts and nuts, a great deal of labor is required for the installation work. is there. Furthermore, since the slope frame made of concrete or synthetic resin remains without corrosive even after the plants and the like have settled, there is a drawback that the growth of the plants is hindered and that the landscape is spoiled. In any of the conventional techniques, since the drainage is not taken into account, the slope due to excessive weight due to water accumulation in the frame body when there is a large amount of rainfall, or due to softening of the topsoil. There was a risk of collapse.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and has a method capable of preventing runoff of a slope surface soil because it has excellent strength, has no distortion, and has a water stopping member. It is an object of the present invention to provide a face frame body, and to provide a slope frame body composition which is excellent in drainage property and can prevent collapse of the slope because a large amount of water does not stay on the slope.

And the flow path C provided in the frame member 11 is opened into the connector 14. That is, as shown in FIG. 10, when the amount of water accumulated in each vegetation part A becomes excessive due to heavy rain or the like, excess rainwater flows into the flow path C from each inflow / outflow hole 13 and flows, and flows from the end port 12A. It flows into the connecting body 14 and flows into the flow path C from the opening 12A of the lower frame member 11. Through such a route, surplus water flows down the slope A, so that the situation in which the slope A collapses without rainwater staying in each vegetation part A for a long time can be solved.

Reference numeral 24 denotes a water-stopping member adhered to the lower surface 3B of the rod 3 over its entire length. Unlike the water-stopping member 5 in the first embodiment, the water-stopping member 24 is narrower than the width of the rod-shaped member 3. It is set to (thin) (see FIG. 12) and is molded from a hard material such as wood so that it can be easily buried in the soft slope A. With this configuration, the soft slope surface soil that easily flows out can be reliably retained. Thus, the frame member 21 is composed of the rod 3, the through hole 22, the plurality of inflow / outflow holes 23, and the water blocking member 24.

Reference numeral 25 denotes a connecting rod inserted into the through hole 22 of the frame member 21 having the above-described structure. The connecting rod 25
Is formed of a hollow tube having a length longer than that of the rod-shaped body 3 and having a running water passage 25A inside.
5B is engraved over the entire length. In addition, a plurality of communication holes 2 communicating with the flowing water passage 25A are formed in the pipe wall of the connecting rod 25.
5C, 25C, ... are perforated over the entire length and randomly.

This embodiment has the above-described structure, and a frame is laid on the slope A by connecting a large number of frame members 21, 21,... Are not different from those of the first embodiment. However, according to the present embodiment, a plurality of inflow / outflow holes 23 communicating with the through-holes 22 are provided in the frame member 21, and the connecting rod 25 inserted into the through-hole 22 has a flow channel 25 </ b> A inside, and a large number of Are characterized by a configuration using a hollow tube provided with the communication holes 25C, 25C,. With this configuration, as shown in FIG. 14, when a large amount of water stays in each vegetation part A as in the case of heavy rain, excess water flows from each inflow / outflow hole 23 into the through hole 22. , And a water passage 25A from each communication hole 25C.
And discharged into the connector 8. The surplus water discharged into the connecting body 8 is discharged into the lower connecting body 8 through the flowing water channel 25A of the connecting rod 25, so that the excess rainwater sequentially passes through this path to the lowland side of the slope A. It can be released quickly.

Although the connecting rods 6 and 25 are made of round bar steel in each of the above-described embodiments, a metal bar other than steel, such as an aluminum bar, may be used. Alternatively, a synthetic resin bar may be used. The synthetic resin bar may be made of a degradable synthetic resin.

[0027]

The present invention has the following advantages because it is constructed as described above. (1) Since a plurality of frame members are connected to each other by a connecting body via a connecting rod, they are excellent in strength, have no distortion, and can reduce a gap with a slope as much as possible. The outflow of slope topsoil can be prevented. Further, since the slope frame can be formed by connecting the frame members in a chain, the work efficiency is superior to the case where the frames formed in advance are assembled and connected. (2) Since the frame member and the connecting rod can be cut at an arbitrary length and connected via a connecting member, it is possible to cope with a case where the slope frame cannot be formed in a rectangular shape on the terrain. (3) According to the third and fourth aspects of the present invention, the frame material is provided with an inflow / outflow hole of water and a flow path, and rainwater is discharged below the slope through the connecting member. The phenomenon that a large amount of water remains can be eliminated, and the collapse of the slope can be prevented. (4) The connecting rod has a thread groove formed on the outer surface over the entire length so that the nut can be screwed in even when the connecting rod is cut to a desired length. Laying work can be performed efficiently. (5) Since a water-stopping member is provided on the lower surface of the frame member to contact or fit into the slope to prevent rainwater from flowing out, it is possible to prevent the collapse of earth and sand due to the flow of rainwater from the slope soil.
