Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope covering material used for a slope covering layer formed for strengthening a slope such as a river bank, a shore, or a slope of a mountain, and a slope using the same. The present invention relates to a coating method.

[0002]

2. Description of the Related Art Conventionally, embankments for revetment have been provided on river shores and shores, and a covering layer for reinforcing the slope has been provided on the upper surface of the slope on the water surface side. In addition, a similar slope-enhancing coating layer is provided on slopes such as mountains to prevent landslides and the like.

[0003] Such a covering layer for reinforcing the slope is constructed by constructing a substantially planar covering wall on the slope, and generally comprises a concrete layer. Almost all work is done on site, such as installing a formwork on the slope and installing a frame-shaped reinforcing bar on the formwork, and then pouring fluid concrete into that area. It was done.

[0004] For this reason, it is necessary to perform all complicated work such as assembling, dismantling, and surface finishing of a mold for forming each portion of the coating layer. As a result, there has been a problem that the working efficiency is poor and a problem that the construction period is long and the cost is high. In addition, there is a disadvantage that a large amount of material is lost. Therefore, in order to solve such a problem, a slope coating method using a frame previously molded in a factory or the like has been developed and has already been implemented.

[0005] That is, in this slope coating method, two types of frames, a vertical frame and a horizontal frame, are formed in a factory, and when necessary for construction, the vertical and horizontal frames are transported to a construction site. . Then, after arranging the vertical frame and the horizontal frame on site, the vertical frame and the horizontal frame are connected to each other, and a reinforcing bar is provided therebetween. Finally, concrete is poured into the slope and the covering wall is constructed to construct a slope covering layer.

[0006]

In the above-mentioned slope coating layer, the vertical frame and the horizontal frame are produced in a factory in advance and used on site, so that the on-site construction work is quite simple and easy. Become something. In addition, there is an advantage that the work period can be shortened because the work is performed skillfully, and the cost can be reduced.

[0007] However, even with the above-mentioned slope coating layer, a considerable part of the work still has to be carried out locally.
This was not satisfactory in terms of work efficiency and the like. For this reason, further ease of construction, shortening of construction period,
Improvements in cost reduction have been desired. In addition, the conventional slope coating layer has a problem that the landscape is spoiled because the ground surface of the concrete is left exposed on the surface or mortar is applied to the surface of the concrete.

The present invention has been made in view of the above-mentioned conventional problems, and the construction work is extremely easy and efficient, the construction period can be shortened, and there is no loss of material.
Further, it is an object of the present invention to provide a slope coating material which makes it possible to reduce costs and further enhances the scenery and is preferable from the viewpoint of natural environment protection, and a slope coating method using the same.

[0009]

In order to achieve the above object, a slope coating material according to claim 1 of the present invention is a slope coating material used for coating a slope such as a revetment wall or a mountain area. The inside of a bag made of a biodegradable resin provided with a water intrusion hole was filled with a base material as soil and a paste capable of absorbing the moisture to fix the base material on the slope. Take the configuration.

[0010] With such a structure, when moisture is absorbed by the base material inside the slope coating material through the moisture penetration hole,
The water comes into contact with the chemical glue mixed in the base material to melt the chemical glue, and a part of the melt enters the ground on the slope side. Then, after that, the chemical paste is solidified in a state of being spread on both the slope coating material and the slope, and the base material which is the base of the slope coating material is bonded to the slope. At this time, since the bag is made of a biodegradable resin, it is decomposed into a gaseous state, volatilized or corroded, and integrated with the soil.

[0011] A slope coating material according to a second aspect of the present invention has a configuration in which a seed of a plant is further mixed into the bag. Therefore, the seeds germinate and grow into plants due to moisture absorption, and the plants cover the surface of the slope covering material. This makes the slope coating material more interesting.

According to a third aspect of the present invention, there is provided a slope covering method in which the slope covering material according to the first or second aspect is fixed on a slope such as a revetment wall or a mountain area using fixing means. Take the configuration. As described above, since the slope coating method simply lays the slope coating material on the slope and fixes it with the fixing means, the work becomes extremely simple, and materials and packaging that must be collected after the construction are completed. There is no work to clean up. Also, no loss of material occurs.

According to a fourth aspect of the present invention, in the slope coating method, the fixing means is disposed between at least one of the slopes and the upper surface of the slope coating laid on the slope. And a rod-shaped fixing member that is fixed to the slope and is fixed to the slope by piercing the slope and reaching the slope. It is configured to be configured.

[0014] Therefore, the positioning of the slope coating material is simplified, the disposing work is facilitated, and the fixing work is also simplified. Next, a slope coating material and a slope coating method using the same according to the present invention will be described in detail with reference to the drawings.

[0015]

1 and 2 show a slope coating 1 according to an embodiment of the present invention. This slope coating material 1
In the bag, a bag 2 made of a biodegradable resin mainly composed of corn starch is filled with a base material 3 made of an artificial soil such as a park. This base material 3 contains chitin,
A chemical paste 4 as a paste consisting of chitosan or the like and a hagi seed 5 are mixed. A large number of small holes 6 for water intrusion are formed in the entire surface of the bag body 2.

The construction of the slope coating layer using such a slope coating material 1 is performed as follows. That is,
If the construction is performed on the slope 8 of the bank 7 on the riverbank as shown in FIG. 3, the slope 8 on the river side of the bank 7 is flattened by leveling, and the entire surface is shown in FIG. As shown, a nylon net lath 9 is provided, and a predetermined portion thereof is fixed with a rod-like fixing tool 10 such as a pin. Next, the slope coating material 1 manufactured in the factory is arranged in advance along the lattice of the mesh laths 9 on the slope 8, and the four corners of each slope coating material 1 are fixed with the pins 11. In this case, it is preferable that the slope coating material 1 is laid from the lower end to the upper end of the slope 8.

Then, another net-like lath 9 is further placed on the slope coating material 1 so as to cover the upper surface of the laid slope coating material 1, and fixed in the same manner. It is preferable that this net lath 9 is shifted from the lower net lath 9 so that it does not coincide with the boundary line of the adjacent slope coating materials 1, 1. Next, water is sprayed on the slope coating material 1 laid on the slope 8 to complete the work of disposing the slope coating material 1. In this case, when the width of the slope 8 is large, the slope 8 is divided into a plurality of places, and the same operation is repeated for each section.

After the completion of the construction work, water sprinkled on the slope coating material 1 penetrates into the inside of the bag body 2 through the small holes 6 and the chemical glue 4
And the chemical paste 4 is brought into a molten state. As a result, a part of the chemical glue 4 is impregnated from the bag body 2 through the small holes 6 into the ground on the side of the slope 8 to bond the base material 3 in the bag body 2 to the slope 8. Further, the bag body 2 is decomposed with time and no longer gasified, and the seeds 5 sprout from the seeds 5 and eventually grow into Hagi.

As described above, the slope coating material 1 is manufactured in advance in a factory or the like, and is transported to the site for construction. Therefore, the troublesome work of assembling a mold for molding and disassembling and removing the mold after molding as in the related art can be omitted. Further, since the work of arranging the slope coating material 1 on the slope 8 is performed along the lattice shape of the mesh lath 9, the slope coating materials 1 are arranged in an orderly manner. Then, fixing of the slope coating material 1 in that state is performed by inserting pins 1 at four corners of the slope coating material 1.
1, the fixing to the slope 8 can be performed in an appropriate state without shifting the slope coating material 1.

Further, the surface of the applied slope coating layer is:
Rather than exposed concrete ground and mortar as in the past, bushes and the like grow thicker. Therefore, the scenery is excellent and interesting, and the strength of the slope 8 is increased.

As described above, in this slope coating method, most of the work is performed in a place other than the site, that is, in a place suitable for work in which facilities such as factories are arranged and manufacturing work can be performed efficiently. Therefore, the construction work on site is extremely simple, in which the slope covering material 1 and the net-like lath 9 manufactured in a factory or the like are laid on the slope 8 and fixed with the pins 11 and the fixtures 10. As a result, the whole work including the work in the factory becomes easy, the work efficiency is greatly improved, and the work can be sped up.

In the above-described embodiment, the mesh laths 9 are arranged on both the upper and lower sides of the slope coating material 1. However, the present invention is not limited to this. It may be only one of between the upper surface of the slope coating material 1 and the upper surface of the slope coating material 1. The net lath 9 is not limited to nylon,
It may be made of metal such as iron.

As the material for the bag 2, any material other than corn starch can be used as long as it is biodegradable and corrodes and integrates with the soil. . Further, the small holes 6 of the bag body 2 may be formed by drilling or by knitting a fibrous thread to form the bag body 2 and the stitches thereof may be used as moisture penetration holes.

Furthermore, as the base material 3, besides bark, artificial soil such as vermiculite or dried natural soil can be used. The seed 5 may be any type of plant suitable for the slope, such as Japanese grass and weeds, other than Hagi, but it is preferable that the seed 5 has good germination and can maintain green throughout the year.

The fixing of the slope coating 1 by the pins 11 is not limited to fixing the four corners of the slope coating 1, but may be performed only at the central portion of the slope coating 1, or may be appropriately performed at a predetermined location. Can be set up. Further, in the above embodiment,
Watering is performed after the laying of the slope coating material 1 and the net-like lath 9, but this may be made to wait for natural rainfall. This further simplifies the work.

[0026]

Since the slope coating material according to the present invention is constructed as described above, it can be transported to a construction site after being manufactured in a factory or the like. For this reason, in the slope coating method using this slope coating material, the construction work becomes extremely easy and efficient, and the work period can be significantly shortened.
Costs can be reduced.

Further, no material loss occurs. In addition, the plants grow on the surface over time after the construction, which makes the scenery excellent and interesting. It is also preferable from the viewpoint of natural environment protection such as greening. Therefore, the practical effect is large.
