Description

The present invention makes it possible to control weeds to green the landscape around slopes, road median strips, guardrails, etc., and to green only targeted plants (about 20 to 30 cm tall, such as ivy). It is related to vegetation greening that also has a sheet.

Weeds that grow on slopes, road separation strips, and guardrails have a negative impact on the landscape as a protective greening due to their high plant height and irregular growth, as well as worsen visibility and impede traffic safety, so weeds grow in huge numbers every year. Weeding work has been carried out at great expense.
Therefore, in recent years, weed control sheets have been developed that are laminated with at least three layers: a surface layer selected from inorganic particles and synthetic resins containing inorganic particles, a modified asphalt layer, and a base material layer as described in Patent Document 1, and weed control sheets that are laminated with at least three layers: a surface layer selected from inorganic particles and a synthetic resin containing inorganic particles, a modified asphalt layer, and a base material layer; A weed control sheet consisting of at least five laminated layers of asphalt and a back layer selected from synthetic resin, rubber, inorganic particles, and synthetic resin containing inorganic particles is laid and fixed in the area to be weeded to prevent weeds from growing. Attempts are being made to do so.

In addition, Patent Document 2 discloses a weed control sheet in which three layers of coated paper, polysheet, and nonwoven fabric are laminated by thermal bonding, planting holes with a diameter of more than ten millimeters are formed at regular intervals in a weed control sheet, and a lattice-like raschel net is formed on the upper surface. An attempt to create vegetation greening using a construction method that combines weed prevention and greening by coating the soil with a few millimeters thick of fertile soil, which is made by adding water to high-quality soil, seeds, fertilizers, protective materials, and stabilizers to form a muddy mixture. is being done.

However, while the weed control using the weed control sheet in Patent Document 1 does not allow weeds to grow, it is becoming a problem that only the weed control sheet is left exposed and deteriorating the local landscape. Furthermore, because the weed control sheet is constantly exposed to the sun's ultraviolet rays, the sheet deteriorates quickly and its durability becomes a problem.
Patent Document 2 discloses that the planting holes of the weed control sheet are not matched to the trunk diameter of each plant, but are standardized to a certain circle, which creates gaps for weeds to grow, and that the planting holes of the weed control sheet are not adjusted to the trunk diameter of each plant, which creates gaps for weeds to grow. Damage to the base of the grass sheet becomes a problem.

In order to solve the above-mentioned problems, the present invention has developed a weed control system that is resistant to damage and corrosion and has excellent weed control and weather protection effects, while also being lightweight and easy to install, allowing only desired plants to grow. It is to provide seats.

Therefore, in order to prevent weeds at the installation location and form a sheet that allows only the desired plants to flourish, from the bottom we started with a black poly sheet that does not allow roots or water to pass through, and a black Russell net that prevents the sheet from scattering due to wind and rain. are stacked and thermally bonded to form one sheet.
Furthermore, dried grass cut into pieces of approximately 2 to 3 mm is adhered to the entire upper surface using an adhesive to form a three-layer weed control sheet.
A certain amount of viscous improved soil is injected into holes made in the weed control sheet according to the shape of the desired plants to form soil that promotes rooting and growth, and the desired plants are planted.
In order to prevent weeds from growing between the openings and the desired plants, a cut is made in the center of the rubber sheet to match the shape of the desired plants, and dried dried grass is cut into pieces of about 2 to 3 mm. is fixed onto a rubber sheet with adhesive to form a weed deterrent sheet. In this case, the square size of the rubber sheet is adjusted according to the trunk diameter of the desired plant.
Apply a weed control sheet to the top of the weed control sheet and secure with metal skewers.
The weed control sheets should be overlapped 10 to 20 cm and fixed using metal skewers to ensure light-blocking properties.

The weed control sheet is laid without any gaps at the construction site, and the construction surface is constantly agglomerated, and it is firmly fixed using metal skewers. Weed control sheets should be stacked 10 to 20 cm over each other to ensure light-blocking properties, and fixed using metal skewers. The weed control sheet is perforated along the shape of the cylindrical structure or the part of the weed control sheet that comes into contact with the desired plants. At the opening, pour improved viscous soil evenly into the gap between the construction surface and the weed control sheet. A greening method using a weed control sheet that allows openings in the weed control sheet to be closed with a weed control sheet, suppressing weed growth through the gaps, and allowing only desired plants to grow.

The greening method using weed control sheets suppresses the growth of weeds at the installation location and allows desired plants to grow and flourish from the planting holes, making it suitable for road median strips, guardrails, and home gardens where weed control is required. In addition, it is possible to green the slopes and improve the local landscape. This construction method can also be used to plant desired vegetation when the construction surface is an artificial thin-layer planting mat, eliminating the need for grass mowing maintenance during construction, such as rooftop greening.

FIG. 2 is a diagram showing that improved viscosity soil is injected into a perforated weed control sheet. It is a figure which shows planting desired plants in a weed control sheet. It is an explanatory view of laying and fixing a weed control sheet to a weed control sheet. FIG. 3 is a diagram illustrating overlapping weed control sheets. FIG. 3 is a diagram showing a rubber sheet with incisions made therein. It is an explanatory view showing the composition of a weed suppression sheet.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an explanatory diagram showing the structure of a weed control sheet. The sheets that form this are made of materials that are lightweight, resistant to damage and corrosion, and do not allow light to pass through.The materials include black polyethylene sheet 1, which is impermeable to roots and water, and polyethylene with 2-4 mm mesh to prevent the sheet from scattering in the wind and rain. The black raschel net sheets 2 are stacked and thermally bonded to form one sheet. Further, dried grass 3 cut into pieces of about 2 to 3 mm is fixed to the entire upper surface using an adhesive to form a weed control sheet 4 having three layers laminated. Dried grass is covered with a black weed control sheet to prevent ultraviolet rays from the sun, thereby reducing deterioration of the weed control sheet and preserving the landscape.

FIG. 2 is a diagram in which a weed control sheet is laid on a construction surface (ground) 5 and holes are opened. The construction surface is constantly agglomerated, and is firmly fixed using gold-metal skewers. The size and shape of the openings are adjusted according to the desired plants. Note that if the weed control sheet is arbitrarily torn vertically and horizontally, weeds will always grow, so it will not have a weed control effect.

FIG. 3 is a diagram showing that improved viscosity soil 6 is injected into the perforated weed control sheet. If there is a gap between the weed control sheet and the construction surface (ground), there will be room for weeds to grow, so the construction surface and the gap are all covered with viscous improved soil 6.

FIG. 4 is a diagram showing the planting of desired plants 7 on the weed control sheet. The weed control sheet is made of a black sheet, and sunlight does not reach any areas other than the openings, preventing weeds from growing. In addition, if stolon-shaped plants are planted in the openings, the humidity and temperature of the ground surface will be maintained, and they will grow quickly and grow as runners, completely covering the surface of the sheet. This prevents deterioration and wear of the weed control sheet from sunlight's ultraviolet rays and improves its weather resistance.

FIG. 5 is an explanatory diagram of laying and fixing the weed control sheet 10 on the weed control sheet. The weed suppression sheet will be explained with reference to FIGS. 7 and 8. Use metal skewers for laying and fixing.

FIG. 6 is a diagram illustrating overlapping the weed control sheets. In order to ensure sufficient light-shielding properties to enhance the weed control effect, the weed control sheets are overlapped 10 to 20 cm and fixed using metal skewers.

FIG. 7 is a diagram showing that cuts have been made in the rubber sheet constituting the weed suppression sheet. A rubber sheet 8 with a thickness of about 0.5 to 2 mm is made by making a notch in the center of the rubber sheet according to the shape of the desired plant. The size of the rubber sheet is adjusted according to the trunk diameter of the desired plant.

FIG. 8 is an explanatory diagram showing the structure of the weed suppression sheet 10. Dried grass 9 cut into pieces of about 2 to 3 mm is fixed to the entire upper surface of the rubber sheet 8 with an adhesive to form a weed deterrent sheet. Dried grass is covered with a black rubber sheet to prevent deterioration caused by sunlight's ultraviolet rays and to preserve the landscape.

This greening construction method is a weed control and vegetation sheet that suppresses the growth of weeds and allows desired plants to thrive.It is lightweight and easy to install, is resistant to damage and corrosion, is weather resistant, and has weed control. It is highly likely that it will be used as a greening material for roads, separation strips, guardrails, slopes, etc. that need to be managed, as well as for restoring the natural environment in landscape formations such as home gardens and parks. be.
