Description

  The present invention relates to a greening method using a greening unit that facilitates greening of a rooftop of a building such as a factory or a high-rise house, a veranda, a deck, and an installation of an event hall.

  Recently, with the rise and density of urban structures, greening of artificial ground such as rooftops and walls of buildings has become an important factor in the formation of urban greening spaces. Rooftop greening is a means of purifying the atmosphere, preventing drying, preventing global warming, and heat islands. It contributes to the prevention of global warming, such as mitigation of phenomena, and is recognized as an indispensable condition for the formation of a living environment including landscapes.

  In addition, the green healing effect is also well-known, and there are many cases where green is arranged in common spaces and exhibition halls inside buildings.

  Many proposals have been made as methods of greening. For example, in Japanese Patent Laid-Open No. 2002-17170, the material is a biodegradable plastic and has a drainage hole in the bottom surface, the cultivation soil is filled in the planting container for mat cultivation, and all the containers are buried in the ground I am trying to measure greening. In this case, the biodegradable planting container is buried in the ground and biodegraded.

  Japanese Patent Application Laid-Open No. 2003-61457 attempts to prevent the roof greening units from being dropped and skipped by connecting the rooftop greening units together. However, in this case, there is no description of the material, and although a drain outlet is provided, a reservoir portion is not provided.

Furthermore, there is no use example as a medium for solid cotton using a polylactic acid-based biodegradable fiber and a polylactic acid-based biodegradable fiber binder.
Japanese Patent Laid-Open No. 2002-17170 JP 2003-61457 A

  An object of the present invention is to enable quick and inexpensive installation on the installation surface for measuring greening, and is a lightweight greening unit in which a material constituting a greening unit other than plants to be grown is biodegradable. Is to supply.

  As a result of diligent research, the present inventors have found that solid cotton obtained by heating biodegradable fibers and a binder has an effective effect as a medium for plants. In addition, the base and the rooting sheet are also formed from a biodegradable material, and the base is provided with a drain port and a water storage portion, thereby completing the present invention.

  In the greening unit of the present invention, a greening plant is grown in advance, and the greening is completed simply by placing the greening unit at the installation location. In other words, it does not require a special process and construction period, and even an unskilled worker can reliably perform the construction. Furthermore, when the greening unit needs to be removed, it can be easily removed and the installation location can be returned to the current state.

  In addition, the greening unit of the present invention is made of hard cotton, rooting sheet, and base used as cultivation soil with biodegradable material, so it does not require high temperature at the time of disposal by incineration and generates harmful gas However, when the soil is buried, there is an advantage in that it naturally returns by erosion decomposition, hydrolysis, etc. by bacteria.

  A polylactic acid-based biodegradable fiber and a binder are mixed, laminated in a cotton shape, and heated to a high temperature in a pressurized state or in a non-pressurized state to form a solid cotton shape. The formed biodegradable planting land is cut into an appropriate size and used as a solid cotton cultivation soil.

  If the greening plant is lawn, grow the lawn with solid cotton cultivated soil, and install it at the installation site when the roots are fully grown.

  A plant to be nurtured according to an embodiment of the present invention will be described in detail as a lawn. 1A and 1B show an embodiment of a base, in which FIG. 1A is a plan view, FIG. 1B is a right side view, and FIG. 1C is a bottom view. In the same figure, 2, 2,... Are drain outlets, 3, 3,... Are water retaining portions, 4, 4, .. are receiving surfaces, and FIG. At this time, the base 1 has a box shape, and the side surface portions 5, 5... Have convex portions 6, 6. Further, the drain ports 2, 2... Are provided on the receiving surface 4, and the water retaining portions 3, 3... Are provided so as to cut the receiving surface 4.

  FIG. 3 is a state diagram when four bases 1 are arranged. At this time, the convex portions 6, 6... And the concave portions 7, 7. In some cases, the protrusions 6, 6,... And the recesses 7, 7,. In some cases, another member may be used for stronger connection.

  4A and 4B show an example of solid cotton, where FIG. 4A is a plan view, FIG. 4B is a rear view, and FIG. 4C is a right side view. In the figure, 11, 11,... Indicate the C plane, but the C plane may not be provided.

  FIG. 5 is a cross-sectional view of the greening unit. A rooting sheet 15 is placed on the receiving surface 4 of the base 1, and further solid cotton 10 is placed thereon, and lawn 20 is planted on the solid cotton 10. In the figure, reference numeral 21 denotes a lawn leaf tip, and 22 denotes a lawn root.

  The plant growing unit requires drainage, and even if there is heavy rain, it must be drainable so that it can be drained in about 1 to 2 days. Will affect. In addition, the water retention must be good, and it will be a problem if the plants wither even after several days of sunny weather in midsummer.

  On the other hand, when irrigating the greening unit of the present invention, the irrigated water reaches from the grass root portion 22 to the lower solid cotton 10, and a certain amount of water is retained in the grass root portion 22 and the solid cotton 10, and more water Reaches under the rooting sheet 15. Here, the base 1 is provided with water retaining portions 3, 3,..., And water is stored in the water retaining portions 3, 3,. Water from the water retaining portions 3, 3... Is discharged from the drain port 2 to the outside of the base 1. The base 1 is provided with a drainage groove 8, and the drainage discharged from the drainage port 2 is easily drained to the outside of the base 1 to be connected to the drainage groove 8. By this, excess water is drained out of the base 1 to prevent plant root rot.

  In addition, the base 1 is provided with the water retention portions 3, 3,... Below the rooting sheet 15 to store moisture and prevent the solid cotton 10 from drying even during the sunshine for several days. Thus, in the tree planting unit of the present invention, the drainage port 2 and the water retention portions 3, 3,.

  Further, the base 1 may not be provided with a drain outlet. When the base 1 is formed of a biodegradable foam, it is possible to loosen the adhesion of the expanded particles depending on the forming conditions. When the adhesion of the foamed particles is loosened, the moisture from the thick part of the base 1 It may ooze out and may be in the same state as opening a fine drainage hole in the entire base 1.

  The lawn to be planted on the base 1 is grown from seeds and completely grown on the solid cotton 10 from the beginning, and the lawn grown on many hectares of soil is peeled off, transferred to the solid cotton 10 and rooted. There is a case. In either case, by shipping in a state rooted in the solid cotton 10, a grassy plaza can be created just by arranging the greening units at the installation site.

  Moreover, since the arranged greening units are grown on the base 1, when the greening units need to be removed, the greening units can be easily removed and the installation location can be returned to the current state.

  The greening unit of the present invention can be planted by placing it on the rooftop, veranda, deck, etc. of a building, planting lawn in the soil, and plant cultivation beginners compared to the conventional method that requires about a month for rooting It can be handled gently.

  Further, the greening unit of the present invention can be easily installed and removed, and can also be used when performing green decoration or the like only for a certain period in an exhibition, department store or the like.

It is the top view of a base, a right view, and a bottom view. It is sectional drawing of a base. It is a state figure when four bases 1 are arranged. It is the top view, back view, and right view of solid cotton. It is sectional drawing of a greening unit.
