[Prior art]
2. Description of the Related Art In recent years, in consideration of environmental issues, resource recycling has become a hot topic. In public construction, the importance of preserving the natural environment and improving the environment in which humans and nature coexist is also emphasized in public works. In particular, the effective use of obstacles generated by logging and the like at construction sites has attracted attention.
The trees cut during the construction of the mountainous areas that open up the mountains become obstructive trees, and after removing some timber, the trunk, foliage and root stock are hardly used and left in the forest or landfilled. And is disposed of by incineration.

[Problems to be solved by the invention]
However, troublesome trees (trunks, branches and leaves, root stocks, etc.) generated at the construction site are irregular in shape, and sometimes embrace a mass of debris, so that they are difficult to handle and transport. That is, the method of leaving the obstacle trees in the forest and disposing of them, for example, impairs the natural scenery, induces fires, disasters, and occurrence of pests. Landfill also causes the ground to collapse. Incineration may cause secondary disasters and pollution such as wildfire, smoke damage, cinders, and residual ash. Therefore, it is a troublesome problem that it cannot be easily dumped or disposed of by landfill incineration.
[0004]
In addition, the hill surface after cutting the obstacle trees is shaved off to become a bare ground where rock surface and inorganic soil are exposed. On these slopes, slope revegetation work is carried out from the harmony with nature and the creation of an environment with peace and moisture, but there is a tendency that the growth and maintenance of the plants that make up the green depend on excessive chemical fertilizers, Questions have been raised about the environmental burden of soil and water quality.
Recently, due to such various problems, it has been entrusted to a specialized disposal company, but the disposal is incinerated, and the disposal costs high and cannot be used effectively.
For example, if a forest with a forest age of about 30 years is developed for a public utility facility, more than 3,000 standing trees with a trunk diameter of about 10 cm will become obstacles per hectare, and the volume of the tree will be reduced by the trunk. branches and leaves in it and extent 120m ³ stumps 50m ^3, do not have to dispose of large amounts of 170m ³ degree together is reality.
