DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for restoring a revetment using plant fiber nets, which can prevent erosion and collapse of the shore and can restore the aesthetic revetment by greening vegetation. is there.

[0002]

2. Description of the Related Art Conventionally, plants are directly planted or planted on vegetation mats at plantations at the boundaries between land and rivers, lakes, marshes, seas, and the like. A method of preventing erosion and collapse and promoting greening vegetation has been implemented.

[0003]

According to the above-mentioned conventional methods, planted plants are often washed away by rainwater, waves, and the like, and there are very few examples of successful revegetation vegetation. The present invention is intended to solve such a conventional problem and to provide a method capable of preventing the erosion and collapse of the shore, as well as reliably restoring the revetment by greening vegetation. .

[0004]

According to the present invention, in order to achieve the above object, a plant fiber net 2 having a scent 3 inserted in an arbitrary direction is immersed in water 4, and a root 3 'growing from the scent 3 is a plant. When entangled with the fiber net 2, the plant fiber net 2 was spread over the easily collapsible boundary between land and rivers, lakes, seas, etc. to prevent collapse and to restore vegetation. It is characterized by the following.

[0005]

[Function] A scent 3 has already been inserted and passed through a plant fiber net 2 which has been transported to a planting area 5 at the easily collapsible boundary between land and rivers, lakes, marshes, the sea, etc. and spread in a stable state. Since the roots 3 ′ grown from 3 are entangled with the net 2, the roots 3 ′ enter the soil 6 immediately after the plant fiber net 2 is laid, and thereby the soil 6
At the same time, the buds emerging from the aroma 3 grow into the trees 9 and the vegetation adapted to the local environment is restored, and the natural landscape is restored, and the habitats and fish of small animals Thus, a natural environment that can be a spawning place can be realized.
Since the net 2 is composed of plant fiber, it is gradually reduced as organic matter to the soil with the passage of time. At the same time, however, the plant is sufficiently rooted, so that it is permanently used as an ecological vegetation seawall. To work.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. First, a plurality of willow scents 3 are appropriately placed in an arbitrary direction and on a vegetable fiber net 2 of a certain size, which is manufactured by braiding a rope 1 in which plant fibers obtained from coconut peel are braided. Through at great intervals,
This is immersed in water 4 stored by any means as shown in FIG. When the root 3 ′ growing from the scent 3 is entangled with the vegetable fiber net 2 as shown in FIG. 2 b, the vegetable fiber net 2 is collapsed between the land and the river, lake, marsh, sea, etc. It is transported to the planting area 5 at the easy boundary. Then, the soil 6 of the planting ground 5 is leveled, and if necessary, the soil is put in, and the plant fiber net 2 is spread thereon. The piles 7 are stably driven at an appropriate interval from each other.
In a planting place where conditions are particularly severe, a stone or the like is placed on the plant fiber net 2 for stabilization. In addition, 8 shown in FIG. 3 is a tree in which buds emerging from the scent 3 grow.

[0007]

As described above, the present invention is to dip the plant fiber net into which the scent is inserted in any direction and soak the roots growing from the scent into the plant fiber net. When the plant fiber net is transported from a field to a planting site, the plant fiber net can be transported in a state of being rolled together with a plant (slave), so that the handling is easy and the transport cost and the construction cost are reduced. is there.

In addition, the scent is already inserted into the plant fiber net which is transported to the planting ground and spread in a stable state, and the roots growing from the scent are sufficiently grown to be entangled with the net. Therefore, immediately after the net is laid, the roots penetrate into the soil and the soil is reliably stabilized, so that erosion and collapse of the shore can be surely prevented, and furthermore, By restoring the vegetation in line with the environment, the natural landscape can be restored and it can be a habitat for small animals and a spawning site for fish, etc., and the water quality is also purified by the growing plants. It has a great effect of improving the natural environment of the country.
