Description

[Technical field]

[0001] This invention relates to vegetation greening that combines weed control for scenic greening of slopes, median strips of roads, around guardrails, etc., with a sheet that enables the greening of only the desired introduced plants (ivy, etc., about 20 to 30 cm tall). [Background technology]

[0002] Weeds growing on slopes, road medians and guardrails not only have a negative impact on the landscape as protective greenery due to their tall height and irregular creeping or elongated growth, but also impair visibility and pose a hindrance to road safety, so huge amounts of money are spent on weeding work every year. In recent years, therefore, attempts have been made to prevent weeds from growing by laying and fixing in areas where weeds should be removed weeds, such as weed control sheets comprising at least three laminated layers, namely a surface layer selected from inorganic particles and synthetic resin containing inorganic particles, a modified asphalt layer, and a base layer as described in Patent Document 1, or weed control sheets comprising at least five laminated layers, including these three layers plus a modified asphalt layer and a back layer selected from synthetic resin, rubber, inorganic particles, and synthetic resin containing inorganic particles.

[0003] Patent Document 2 describes an attempt to achieve both weed control and greening by laminating three layers of coated paper, poly sheet, and nonwoven fabric using thermal bonding, forming planting holes with a diameter of several 10 mm at regular intervals in the weed-control sheet, attaching a lattice-shaped Russell net to the upper surface, and coating the surface with a layer of fertile soil made by adding water to good quality soil, seeds, fertilizer, protective material, stabilizer, and a muddy mixture, to a thickness of several millimeters.

[0004] However, while the weed control method using the weed control sheet in Patent Document 1 prevents weeds from growing, it causes the bare weed control sheet to spread and deteriorates the local landscape, which is becoming a problem. Furthermore, because the weed control sheet is constantly exposed to the sun's ultraviolet rays, it deteriorates quickly and its durability becomes an issue. In Patent Document 2, the planting holes in the weed control fabric are not adjusted to fit the trunk diameter of each plant, but are standardized to a fixed circular size, which results in gaps through which weeds can grow, and damage to the base of the weed control fabric as the trees grow.

[0005] [Patent Document 1] JP 2002-272348 A [Patent Document 2] JP 2017-131170 A Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention aims to solve the above problems by providing a weed control sheet that is resistant to damage and corrosion, has excellent weed control and weather resistance, and yet has a vegetation function that allows only desired vegetation to grow thereon and is lightweight and easy to install. [Means for solving the problem]

[0007] Therefore, in order to form a sheet that can control weeds at the installation site and allow only desired plants to grow, a single sheet is formed by layering from the bottom up a black poly sheet that is impermeable to roots and water, and a black russell netting that prevents the sheet from scattering in the wind and rain, and then heat-bonding them together. Furthermore, dried dead grass cut into pieces of about 2 to 3 mm is attached to the entire top surface using adhesive, forming a three-layered weed-control sheet. A certain amount of clay-improved soil is injected into holes in the weed-control sheet to form soil that promotes rooting and growth of the desired plants, and the desired plants are then planted. To prevent weeds from growing through the gaps between the openings and the desired plants, a 0.5-2 mm thick cut is made in the center of the rubber sheet to fit the shape of the desired plants, and dried grass cut to about 2-3 mm is glued onto the rubber sheet to form a weed-suppressing sheet. The dimensions of the rubber sheet are adjusted to fit the trunk diameter of the desired plants. A weed-suppressing sheet is placed on top of the weed control sheet and secured in place with metal skewers. To ensure shading, overlap the weed control sheets by 10 to 20 cm and secure them in place using metal skewers.

[0008] The weed-control sheet is laid without gaps at the application site, and the application surface is always azelled, and is firmly fixed in place using metal skewers. Weed-control sheets are overlapped by 10-20cm to allow for shading, and fixed in place using metal skewers. Holes are made in the weed-control sheet where it comes into contact with cylindrical structures or desired vegetation, following their shape. Clay-improved soil is injected evenly into the gaps between the application surface and the weed-control sheet at the openings. The openings in the weed-control sheet are sealed with a weed-inhibiting sheet, preventing weeds from growing through the gaps, allowing only desired vegetation to grow, in this weed-control sheet greening method. Effect of the Invention

[0009] The greening method using weed-control sheets suppresses the growth of weeds at the installation site and allows desired plants to grow and flourish in the planting holes, making it possible to green slopes and improve the local landscape in addition to road medians, guardrails, and home gardens that require weed control. This method can also be used to plant desired plants when the construction surface is an artificial thin-layer planting mat, and eliminates the need for maintenance such as mowing when constructing rooftop greenery.

[0011] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. EXAMPLES

[0012] Figure 1 is an explanatory diagram showing the structure of a weed control sheet. The sheets that make up the sheet are all made of lightweight material that is resistant to breakage and corrosion and does not transmit light. Black poly sheet 1, which is impermeable to roots and water, and black polyethylene raschel net sheet 2 with a mesh size of 2 to 4 mm, which prevents the sheet from scattering in the wind and rain, are layered together and thermally bonded to form a single sheet. Furthermore, dried dead grass 3 cut into pieces of about 2 to 3 mm is fixed to the entire top surface using adhesive, forming a weed control sheet 4 with three layers laminated together. The dried dead grass covers the black weed control sheet and serves to reduce deterioration of the weed control sheet by protecting it from ultraviolet rays from the sun, while also preserving the landscape.

[0013] Figure 2 shows the weed control sheet laid on the construction surface (ground) 5 and holes drilled. The construction surface is always azelled, and is firmly fixed in place using metal skewers. The size and shape of the holes are processed according to the desired vegetation. Note that if the weed control sheet is arbitrarily torn lengthwise and widthwise, weeds will inevitably grow and the weed control effect will not be achieved.

[0014] Figure 3 shows the weed-control sheet with holes after the clay-improved soil 6 has been poured into it. If there are gaps between the weed-control sheet and the construction surface (ground), they will give weeds room to grow, so the construction surface and all gaps are covered with the clay-improved soil 6.

[0015] FIG. 4 is a diagram showing planting desired plants 7 in the weed control sheet. The weed control sheet is made of a black sheet, and sunlight does not reach areas other than the holes, preventing weeds from growing. If creeping-stem plants are planted in the holes, they will develop quickly as the moisture and temperature of the ground is maintained, and they will grow as runners and completely cover the surface of the sheet. This prevents deterioration and wear of the weed control sheet due to ultraviolet rays from sunlight, and improves weather resistance.

[0016] Fig. 5 is an explanatory diagram of laying and fixing the weed suppression sheet 10 to the weed control sheet. The weed suppression sheet will be explained in Figs. 7 and 8. A metal skewer is used for laying and fixing.

[0017] Figure 6 is a diagram explaining how to overlap weed control sheets. To ensure sufficient shading to enhance the weed control effect, overlap the weed control sheets by 10 to 20 cm and secure them in place using metal skewers.

[0018] Figure 7 is a diagram showing how cuts have been made in the rubber sheet that constitutes the weed suppression sheet. A cut is made in the center of the rubber sheet, about 0.5 to 2 mm thick, to match the shape of the desired plant, forming rubber sheet 8. The size of the rubber sheet is adjusted in dimensions to match the trunk diameter of the desired plant.

[0019] Figure 8 is an explanatory diagram showing the structure of a weed suppression sheet 10. Dried dead grass 9 cut into pieces of about 2 to 3 mm is fixed with adhesive to the entire upper surface of a rubber sheet 8 to form a weed suppression sheet. The dried dead grass is covered with a black rubber sheet to prevent deterioration due to ultraviolet rays from sunlight and to preserve the scenery. [Industrial Applicability]

[0020] This greening method results in a sheet that combines weed control and vegetation, suppressing the growth of weeds and allowing desired vegetation to flourish; it is lightweight and easy to install, is resistant to damage and corrosion, and is weather resistant, making it highly likely to be used extensively in the future as a greening material for roads, median strips, guardrails, slopes, etc. where weed control is required, and as a greening material for restoring the natural environment in landscaping home gardens, parks, etc. [Explanation of symbols]
