Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is established by setting horizontal intervals or vertical intervals on slopes at risk of avalanche,
The present invention relates to an avalanche prevention pseudo tree for preventing an avalanche.

[0002]

2. Description of the Related Art Conventionally, on slopes where there is a risk of avalanche, avalanche prevention fences such as fences and suspension fences that prevent occurrence of avalanche are arranged horizontally or vertically. Recently, a pseudo-tree for avalanche prevention has been developed that has a relatively simple structure and is easy to construct and adapted to the natural environment.

The above-described avalanche prevention pseudo tree has a trunk portion a formed of a steel pipe or the like and a branch portion b formed of a large number of steel pipes orientated obliquely upward to a trunk portion a formed of a steel pipe or the like as shown in FIG. A pseudo tree c in which the surfaces of the trunk portion a and each branch portion b are formed into a bark shape (by shape, coloring, etc.) by projecting in multiple stages and in multiple directions.
Then, the lower end of the pseudo tree is fitted to each pile foundation d that is placed with horizontal intervals or vertical intervals on the slope s to establish it, and the top of the pseudo tree c is attached to the pile foundation e that is placed on the upper part of the slope. It is connected by stays w to make it adapt to the natural environment and receive snowfall to prevent avalanche.

[0004]

In the conventional pseudo-tree for preventing avalanche, the surface of the trunk and a large number of branches are made into a bark shape (shape, coloring, etc.) to form a pseudo-tree shape as described above. Especially in summer etc., it is seen in dead trees and it is not familiar with the natural environment,
In addition, each branch part has a limit in its proof strength and is deformed by a snow load, so that there is a limit in snow receiving performance. In addition, if the snow load on the left and right sides of the Suspect Tree becomes uneven due to changes in the slope, etc., the Suspect Tree will be tilted to the left and right, and the landscape will be impaired.

The present invention was developed in order to solve the above problems, and the object of the present invention is to provide a large number of leaves on the branches of a pseudo tree or a large number of leaves on the branches. A net with leaves is stretched, a base plate is provided and each branch is connected with a reinforcing member to match the natural environment and enhance the snow protection performance to prevent reinforcement and subsidence and tilt left and right. It is to provide a pseudo-tree for avalanche prevention which has improved anti-avalanche performance, avalanche prevention performance, and reliability.

[0006]

DISCLOSURE OF THE INVENTION The present invention is directed to an avalanche prevention pseudo tree in which a pseudo tree formed by attaching a large number of branch sections to a trunk section formed of a steel pipe or the like is established on a slope by a pile foundation or the like, and at least the branch section. By providing a large number of leaves on the artificial tree, it is possible to further match the natural environment with the artificial environment.By laying a net with multiple leaves on each branch and trunk of the artificial tree, the artificial environment is matted and reinforced to prevent snow. Improve the performance, and provide a base plate that extends at least left and right at the bottom of the artificial tree and is arranged on the slope,
Alternatively, by connecting the branch portions with a reinforcing member, the branch portions are reinforced to prevent subsidence and prevent lateral tilting of the artificial tree.

[0007]

[Operation] In a pseudo-tree for avalanche prevention, in which a pseudo-tree formed by attaching a large number of branches to a trunk formed of steel pipe, etc. was established on a slope by a pile foundation, etc. In the same way as a natural tree, it is made to match the natural environment, and a net with many leaves is stretched on the trunk and each branch of the artificial tree to further strengthen the snow protection performance by reinforcing it with the mat to the natural environment. A base plate that extends at least to the left and right on the artificial tree and is arranged on the slope is provided, or each branch is connected with a reinforcing member to reinforce it to prevent the artificial tree from sinking due to falling snow and to prevent the artificial tree from tilting left and right. It has excellent artificial wood performance, avalanche prevention performance, and reliability.
