Description

Technical Field

[0001] The present invention aims to control weeds over a long period by suppressing the light rays around the columnar bodies such as guardrails and road signs installed on roads, and to achieve landscape greening with short grass plants, and environmental protection relating to weed control and greening around columnar bodies that combines weed control and greening.

Background Art

[0002] Weeds grow in the soil around columnar objects such as guardrails and utility poles installed on roads, the grass height increases, the visibility is poor, which hinders traffic safety and also has an adverse impact on the surrounding landscape. Therefore, a huge amount of money is spent every year on weeding work. Moreover, in the weeding work around these columnar objects such as utility poles, there is a risk of unexpected accidents because the blade of the lawn mower hits the base of the utility pole or columnar object. Therefore, for the area near the base of the utility pole or columnar object, weeding work is carried out with extra manpower and time. Furthermore, due to a shortage of manpower, the number of areas that are not properly managed is increasing.

[0003] Therefore, in recent years, a construction method has been developed in which incisions are made in a weed control sheet to cover the column and the column and the weed control sheet are fixed with tape or the like to control weeds and green the surrounding area. (Patent Document 1)

[0004] However, in the method for controlling weeds around the column in Patent Document 1, since the column and the weed control sheet are fixed with tape, there are no problems with functionality for several years (1 - 2 years) after installation. However, due to recent intense heat and heavy rain, the tape peels off, light rays enter through the gaps, and there are Damage to the weed control sheet itself due to weed growth, collapse due to soil decay beneath the weed control sheet, etc. problems caused by flying seeds and the like.

Summary of the Invention

[0006] To solve the above problems, this invention creates a structure that prevents sunlight from entering through the gap between the weed control sheet and the support post over a long period of time, thereby preventing weeds around the support post and improving the local landscape without compromising traffic safety around the support post. And environmental protection (CO2 reduction) and prevention of soil decay. Short grass plants that can be used for this purpose (Flowers) To provide weed control and greening around support posts that also incorporates greening. [Means for solving the problem]

[0007] At the base of the column, a blackout sheet (rubber sheet) is installed, with a cylindrical section in the center of the rubber sheet having the same diameter as the column and a single cutout formed therein. On top of that, a weed control and greening sheet is installed, consisting of a nonwoven fabric sheet, a black mulch sheet, and a Russell net, each several tens of centimeters square, with a cylindrical section in the center having a diameter a few centimeters smaller than the diameter of the column (guardrail, utility pole, etc.), and a single cutout formed therein so that it can be installed at the base of the support column, etc., and installed around the column. To prevent light from entering through the cutout, the weed control and greening sheet is glued to the bottom of the cutout. Conventional methods of fixing with tape, etc., deteriorate within a few years, so for long-term use... To reinforce the base of the column and prevent sunlight from entering, wrap sponge tape around the weed-proof and greening sheet, then secure it with cable ties.

[0008] A weed-suppressing and greening sheet is laid and secured at the base of the column, and planting holes several millimeters in diameter are made in the weed-suppressing and greening sheet at regular intervals. Ground cover plants such as creeping thyme and ice plant are planted in these planting holes along with fertile soil to suppress weeds and green the area around the column. [Effects of the Invention]

[0009] Weed control and greening around the pillars that block sunlight suppress weed growth in the installation area over a long period of time, allowing desired plants (ground cover plants such as Lippia nodiflora) to grow. Flowers and plants This enables the growth of plants, reduces the effort required for weed control, alleviates labor shortages, improves traffic visibility leading to accident prevention, and enhances the local landscape. And environmental protection (CO2 reduction) and prevention of soil decay. This method of weed control and greening around the pillars can also be achieved.

[0010] Furthermore, the weed control and greening sheets, made from materials that are resistant to deterioration, are lightweight and easy to install. They ensure durability and suppress moisture evaporation and weed growth through the use of multiple sheets, providing weed control and greening around pillars where desired plants can grow for a long period. As the plants grow and spread across the sheets like runners, the effects of sunlight and wind and rain are reduced, thus extending the lifespan of the sheets. [Brief explanation of the drawing]

[Figure 2] This is an explanatory diagram showing the structure of a weed control and greening sheet and a blackout sheet (rubber sheet). [Figure 3] This is a perspective view showing the installation of a weed-proof and greening sheet around the base of a column. [Figure 4] This is a perspective view showing the reinforcing section that suppresses light rays around the base of the column. [Modes for carrying out the invention]

[0012] Specific embodiments of the present invention will be described in detail below with reference to the drawings. [Examples]

[0013] Figure 1 is an overall view of a weed control greening sheet for the base of pillars such as guardrail posts and utility poles, which suppresses weed growth by blocking sunlight from entering the base of the pillars. The weed control greening sheet 1 for the base of pillars that blocks sunlight is composed of a nonwoven fabric 1a, a black mulch sheet 1b, and a Russell net 1c, in that order, with a diameter several centimeters smaller than the diameter of the pillar 2 such as a guardrail or utility pole in the center of the sheet 1. A single cut 3 is formed so that it can be installed at the base of the pillar, and the sheet is installed around the pillar. The weed control greening sheet is attached to the bottom of the cut 3 so that sunlight does not enter through the cut 3. A blackout sheet 5 is installed in advance below the weed control greening sheet to prevent sunlight from entering the base of the pillar 2. The blackout sheet 5 is a rubber sheet several centimeters square with a cylinder of the same diameter as the pillar 2 formed in the center and a single cut. Prevents deterioration over a long period and suppresses light rays. Wrap the sponge tape 4a around the tape and secure it with the cable tie 4b.

[0014] Figure 2 shows the configuration of a weed control and greening sheet 1 and a blackout sheet (rubber sheet) 5 for weed control and greening at the base and around the column. From below, a nonwoven fabric 1a blocks planting and light, a black mulch sheet 1b on top of that blocks water and light, and a blackout sheet (rubber sheet) to prevent damage to the black mulch sheet. It assists in the elongation of plants. This is a weed control and greening sheet 1 composed of Russell net 1c in that order.

[0015] The weed control and greening sheet is a weed suppression sheet made of three sheets of a corrosion-resistant material that blocks light and plant sprouts, maintaining its shape for a long period of time. By planting ground cover seedlings, the high heat accumulation within the sheet due to solar heat is reduced, thereby suppressing the deterioration of the sheet itself and allowing for long-term suppression of weed growth. The blackout sheet (rubber sheet) is used to reinforce the sheet and prevent light from entering through the gaps between the support posts and the weed control and greening sheet due to deterioration.

[0016] Figure 3 shows the state where a weed control sheet around the base of the columnar body is installed and fixed to the ground. The installation method is as follows: after installing the dark curtain sheet (rubber sheet) 5, the weed control and greening sheet 1, the sponge tape 4a, and the binding band 4b at the base of the columnar body 2, drive and fix the stop pins 6 composed of the large head nails 6a, washers 6b, and rubber sheets 6c at the four corners of the weed control and greening sheet 1.

[0017] For the weed control and greening sheet around the base of the columnar body, plant holes with a diameter of several millimeters are formed at arbitrary locations, and ground cover plants such as Saxifraga stolonifera and Matricaria chamomilla are planted in these plant holes together with fertile soil to achieve weed control and greening around the columnar body and improve the landscape. And environmental protection (CO2 reduction) and prevention of soil decay. This can be achieved. Also To suppress light rays over a long period of time. By installing the dark curtain sheet, sponge tape, and binding band, early deterioration due to intense heat and heavy rain can be prevented, and weed control management is not required for a long period.

[0018] Figure 4 shows the configuration of the reinforcement part for preventing light from entering the base of the support column. The sponge tape 4a for suppressing the light from the base of the support column, which is installed on the weed control and greening sheet 1, Early is the binding band 4b for preventing peeling due to tape deterioration.

[0019] The reinforcement part is configured to prevent early deterioration caused by fixing with an existing tape, and it has higher functionality from the perspective of suppressing light compared to fixing only with the tape. If sunlight enters from the base of the support poles, weeds will grow from airborne seeds, increasing the likelihood of deterioration and damage to the sheet itself.

Industrial Applicability

[0020] The weed control and greening sheet around the columnar body that suppresses light is a weed control and greening that combines weed control and greening, suppressing the growth of weeds and allowing desired plants to thrive. It is easy to construct, maintains its shape for a long time, and the weed suppression effect And environmental protection (CO2 reduction) and prevention of soil decay. is exerted for a long time. As a weed control and greening method around columnar bodies such as guardrails that require weed control management, it has a high possibility of being widely used in the future. Furthermore, since this weed control and greening sheet is easy to process and can exert the same effect on various shapes of structures, it has a high potential for use as a weed control and greening method around structures other than pillars.
