Embodiments of the present invention will be described below with reference to the drawings.

By the way, in recent years, the expansion and propagation of bamboo forests, which are representative of Munetake bamboo, has become a hot topic. In particular, in Shizuoka Prefecture, the bamboo forest area was 3860ha in 1998, but it was 5180ha in 2000, and is continuing to expand.

Bamboo forests were once maintained and managed to produce bamboo shoots and bamboo, but the use of bamboo has drastically decreased with the advent of so-called plastics.

In recent years, bamboo shoots have also been received in large quantities at low prices from China, and production has decreased.

As a result, bamboo forests are abandoned, expanding their power to surrounding forests and farmland.
(Bamboo forest expansion mechanism)
Each year, Munetake bamboo stretches the rhizomes to give out bamboo shoots. This bamboo shoot grows from 10m to 20m in just 3 months.

Plants that grow above the bamboo forest will not be exposed to the sun, and will lose their growth space and die.

While bamboo forest is harvested every year while it is used for the production of bamboo shoots and bamboo, the number is adjusted. Go.

According to one study, bamboo forests expand at a rate of about 2 to 3 meters per year, and in some places they can spread at over 6 meters per year.
(Problems of neglected bamboo forest)
Bamboo forests have created a beautiful satoyama landscape together with past miscellaneous forests and fields, but the bamboo forest has expanded and one side has become a bamboo forest.

Bamboo groves are tall and dense, so light and space are scarce in the grove, and other plants do not grow. As a result, the number of animals that live there will also be reduced.

The cedar and cypress plantations lose their momentum and die with the invasion of Misotake. Underground stalks grow in orchards, tea fields, and vegetable gardens.

Since Misotake is rooted at a depth of up to 50 cm, it is relatively shallow compared to other trees and it is difficult to maintain the strength of the ground, and once there is a rain disaster, there is a high possibility of causing landslides.
(Use of bamboo)
The expansion of abandoned bamboo forests will not only lead to the collapse of satoyama, but also has a great impact on the ecosystems of animals and plants, and the damage caused by disasters may spread widely, so the use of bamboo is an urgent task.

Some organizations work on the conservation of satoyama while enjoying bamboo craft and bamboo charcoal grilling, but the current situation is that they cannot keep up with the expansion of bamboo forests. In addition, most bamboo forests are privately owned, and it is almost impossible to succeed if there is no land owner's awareness reform.

If the value of bamboo is increased and the value of labor can be obtained, it is clear that the landowner will always improve the bamboo forest.

The most important thing when considering the use of bamboo is to think of a method that can be used in large quantities.

In addition, it is desirable to use up not only a part of the bamboo but all of it, and it is important to devise a usage method according to the thickness.

When connecting, a straight portion of a cross portion in the connecting tool 6 is installed on the bamboo base material 1 in parallel with the longitudinal direction of the base material 1, and another shape is formed so as to be substantially perpendicular to the base material 1. The bamboo base material 1 is placed on the straight part of the cross part that is orthogonal.

And the wide part 7 of the said connecting tool 6 is rounded along the outer periphery of each said bamboo base material 1,1, and this bamboo base material 1,1 is fastened by the fastening member 8 from the upper part of each wide part 7. It shall be.

Here, the fastening member 8 is preferably a flexible locking band, but may be a flexible annular member or the like.

By installing the lattice-shaped bamboo manufacturing frame material 3 configured in this way on the slope 4, the effect of preventing the slope 4 from collapsing can be obtained. Moreover, the appearance appears as bamboo, so you can create a peaceful natural space.

Although not shown in the drawing, it is desirable to lock the bamboo manufacturing method frame material 3 by placing a substantially U-shaped anchor member 5 or the like into the slope 4 ground from above.

Moreover, although the said bamboo manufacturing method frame material 3 will corrode after a long period, since the rod-shaped concrete member 20 with which the inside of bamboo material was filled still remains, the function as a method frame material can be ensured over a long period of time.

In this case, an inorganic concrete surface appears as an appearance, but when a long period of time elapses, the vegetation within the legal frame is overgrown and the concrete surface is hidden.

In this way, by planting in the lattice frame of the bamboo manufacturing method frame material, it is possible to create a beautiful landscape with the green of the plant and to prevent the slope from collapsing.
