Description

In this paper, we propose a new type of plant structure for cultivating plants.

The present invention relates to a plant pot structure of a low-impact development facility. More specifically, the present invention relates to a plant pot structure of a low-impact development facility, The present invention relates to a potted vegetation-type vegetation structure of a low-impact development facility capable of reducing the amount of environmental pollutants generated in the environment and reducing the amount of rainwater while changing the surrounding landscape freely.

The LID (low impact development) technique is a land use planning and urban development technique that minimizes the aquatic ecosystem from urbanization through infiltration and storage, It is a citizen rainwater management system and technology in connection with land use plan, utilizing natural drainage and natural soil cleansing ability. It has the effect of reducing heat island, improving air quality and storing carbon.

Korea is classified as a water-scarce country, and carbon emissions are gradually increasing, so rainwater utilization, groundwater filling, temperature reduction, and carbon emission reduction are required. Therefore, there is a need for a landscaping facility capable of treating vegetation using rainwater.

As urbanization proceeds, the rain can not be absorbed into the soil, and it quickly flows into the river with pollutants. As a result, groundwater is becoming depleted and floods occur due to an abrupt increase in river flow. Contamination on the road pollutes the river as it is discharged along with rainwater.

Low-impact development (LID) facilities based on low-impact development techniques can be used to infiltrate contaminated water into the ground, , Or it is distinguished from the conventional impermeable type treatment such as the treatment by gradually permeating.

Various technologies and techniques have already been developed and applied globally in order to realize low impact development (LID). Most of these technologies are processed through mechanisms such as infiltration, filtration and adsorption to increase groundwater content, soil moisture content , Evapotranspiration and so on. Finally, it maintains groundwater level and improves the amount of penetration due to decrease of impervious layer to prevent desertification and reduces problems such as heat island phenomenon in the city.

Such low impact development (LID) facilities often include soil layers, which act as a base layer of plants planted at the top of the facility and remove and treat the initial nonpoint sources do. The soil to be used is a cultivation soil, which means a soil layer in which plants roots and grows as a foundation for growing plants in agriculture. Generally, it contains drainage and nutrients. It is a soil that can apply various techniques such as wood carvings, aggregates, and pans to the surface layer as a landscape element.

Low Impact Development (LID) is a facility based on vegetation that features vegetation inside and around the facility to add pollutant treatment and landscape elements to biological plants. In order to achieve this, the vegetation soil, which is called cultivation soil, should be used as a foundation in agriculture, and it should be able to stably provide the purification effect and the growth effect of the plant.

Low Impact Development (LID) includes tree box filters, green roofs, vegetable structure pollen or plant planters, dry wells, permeable pavements, Porous Pavement, Sand Filter, Rain Barrel, Bioretention, and Infilteration Trench. It is equipped with infiltration pail, permeable pavement, sand filtration device Vegetation soil of all facilities is used.

These low-impact development (LID) facilities allow rainwater to be absorbed into the soil, thereby enriching the groundwater and filtering out contaminants through the mid-soil action. Rainwater flows slowly through the soil to the rivers, which helps to prevent flood damage. Low-impact development facilities build such a healthy water circulation system to prevent floods, cool the city, and eliminate environmental pollutants to prevent river pollution. In addition, the city will provide a green space to improve beautification and enrich the natural environment to create a satisfying living environment.

As a conventional low-impact development (LID) facility, Korean Patent No. 10-1578551 (vegetation residence site for prevention of good pollution and healthy urban environment, Korean Patent No. 10-1635595 (tree of low impact development with pre- Korean Patent No. 10-1603588 (Nonpoint Source Pollution Reduction Apparatus Using Ecological Circulation), Korean Patent No. 10-1365672 (Natural Circulation Type Wood Flowerpot Filtration System), Korean Laid-Open Patent Application No. 2013-0134271 And a rainfall infiltration storage facility on the road side), Korean Laid-Open Patent Application No. 2016-0022140 (expansion type infiltration plant facility that enables vegetation growth by storage and evaporation due to infiltration of rainwater).

As a low-impact development facility, vegetation structure pollen (or planted flower pots) plays a role in securing green spaces in urban spaces where green spaces are lacking by planting plants and flowers for outdoor landscaping to brighten the environment around the roads. In other words, the vegetation structure pollen or plant cultivation pollen is a facility that regulates the amount of rainwater and reduces pollutants by forming a filtration layer in the form of a flower bed in which water can permeate, thereby impregnating the soil with rainwater. It has the function to reduce the environmental pollutants generated, reduce the amount of rainwater, and improve the surrounding landscape. Vegetation structure Pollen or plant cultivation pot can be applied to the area around the road, the urban roadside tree, the sidewalk, the parking lot, the urban green space, the buildings, and the apartment complex parks.

However, there has been a problem that it is difficult to improve the vegetation structure plant (or plant cultivation plant) once installed as a low-impact development facility, while changing the surrounding landscape freely according to the type of plant.
