Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a park, an orchard,
The present invention relates to an earth surface covering material using bamboo powder for covering and protecting the ground on which street trees have grown, river embankments, side slopes of roads and railways, a construction method thereof, and a civil engineering structure and a production method thereof. .

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Publication No. 3-23681, there has been a bamboo powder obtained by pulverizing bamboo (mainly Moso bamboo) and processing it into a powder as a covering material to be spread on the ground.
This bamboo powder is excellent in impact resistance (cushion), water permeability, heat retention, deodorant, antiseptic, water absorption and the like. And
Compared to soil and sand, it is much lighter and harder to rot,
It is slightly alkaline, harmless and non-toxic. It also has a repellent effect against pests and the like, and it is possible to control plant growth (dwarfing and growth promotion) by mixing with soil and organic fertilizer.

[0003] In addition, bamboo flour has been used as a substitute for surface sand in horse training areas, parks, playgrounds and golf courses. They were also laid in horse and other livestock barns as a substitute for bedding. In addition, in order to suppress the overgrowth of weeds, they may be laid on the roots of street trees such as the median strip of roads.

[0004]

In the case of the prior art described above, when used by laying on a sidewalk or the like, a predetermined amount of water is added to bamboo powder, which is laid on the ground or the like which has been leveled and spread with a roller or the like. Therefore, it was soft, easily spilled out when the amount of rain increased, and easily scattered by a strong wind or the like in a dry state. For this reason, the method of laying bamboo powder is not suitable for slopes such as mountain roads and bank slopes.

[0005] On the other hand, bamboo as a raw material of bamboo powder uses waste bamboo produced when bamboo shoot production farmers or the like thin out parent bamboo every year. It could not be consumed by the method of use, and the disposal of excess waste bamboo required a lot of labor and cost. Similarly, disposal of waste bamboo by clearing and clearing in land reclamation and development work was also expensive.

The present invention has been made in view of the above-mentioned conventional problems, and is a coating material containing bamboo powder, which is resistant to rain and wind, has a moderate softness, and is suitable for slopes. An object of the present invention is to provide a usable earth surface covering material, a construction method thereof, a civil engineering structure, and a manufacturing method thereof.

[0007]

It is a surface covering material. Further, it is a mixture of an admixture such as an adhesive and a fertilizer.

[0008] The present invention is also a method for constructing a soil covering material in which bamboo powder made of bamboo powder, cement and water are mixed and spread over the ground surface, and the cement is hardened. In addition, bamboo powder and soil, and a soil covering material mixed with water and plant seeds for covering the surface is spread on the ground surface, and the seeds of the plant are germinated, and the soil covering material is spread. This is a method of applying a soil covering material for growing the above plants on the surface of a place where the plant has grown. Further, a fertilizer or an admixture may be mixed.

Further, according to the present invention, a covering material in which bamboo powder made of bamboo powder and plant seeds are mixed is laminated on the surface of a structural member such as a secondary concrete product standing on the ground. It is a civil engineering structure. Alternatively, it is a civil engineering structure in which a covering material in which bamboo powder made of bamboo powder and cement are mixed is laminated on the surface of a structural member installed on the ground. Further, a layer of bamboo powder made of bamboo powder may be integrally formed on the surface of the structural member.

Further, according to the present invention, a bamboo powder made of bamboo is put into a mold for forming a structural member installed on the ground, and then concrete is poured into the mold to integrate the bamboo powder layer on the surface of the structural member. This is a method for producing a civil engineering structure formed in the above.
The civil engineering structure referred to in the present invention includes a building structure in addition to a so-called civil engineering structure.

The covering material using bamboo powder according to the present invention is a mixture of bamboo powder and cement, or bamboo powder, soil and plant seeds. It has deodorant properties, etc., and has appropriate hardness and toughness due to the action of cement and plants. It is resistant to rain and can be securely attached to slopes such as slopes.

[0013]

[Table 1] The above ratio can be set as appropriate, and the ratio between the fine and coarse bamboo powder may be equal to each other, and the ratio can be set as appropriate.

Next, a construction method according to this embodiment will be described. First, weeds on the ground 12 are removed, and a formwork 15 is placed on the leveled ground 14 that has been flattened. The covering material 10 mixed sufficiently by the mixer at the above-described mixing ratio on the ground surface 14 surrounded by the formwork 15 is mixed with the covering material 10 in the same manner as in concrete casting.
Cast to a thickness of 10 cm. The mold 15 is provided with the coating material 10.
Remove after curing.

According to the covering material 10 of this embodiment and the method of applying the same, the covering material 10 of bamboo powder mixed with cement has an appropriate hardness, so that it can scatter and flow even in a strong wind or heavy rain. It is durable and does not grow weeds. Further, the hardness and strength of the coating material 1
It can be freely adjusted by changing the above composition of 0. Further, since the covering material 10 contains a large amount of bamboo powder, the covering material 10 has water permeability and water retention, and water does not accumulate on the surface of the covering material 10 and water quickly penetrates into the soil. And, since it has cushioning property and durability, it may be applied to the sidewalk, and has a good feeling when walking, and it is safe with little impact when it falls.

Next, a second embodiment of the present invention will be described with reference to FIG.
It will be described based on. This embodiment is a construction method in which the covering material 16 is used for covering a slope of a road side surface. The covering material 16 to be used is a mixture of the same raw materials as in the above embodiment at the same compounding ratio, mixed with an appropriate fertilizer and seeds of several kinds of plants.
