{Protection Plate Module for Reducing Non Point Source Pollution and Supplying Water Strip Green Fields of LID-Based Rainwater Recycling Type}

The present invention relates to a LID-based rainwater circulation type non-point pollution reduction and irrigation band green protection plate module, and more particularly, to a green belt green along the roadside recorded in the form of a band along the roadside. LID-based rainwater circulation type non-point pollution reduction and irrigation belt green areas that can efficiently reduce non-point pollutants on roads and sidewalks while circulating rainwater after filtering and collecting water, and protecting green areas planted with street trees It is about the protection plate module.

In order to preserve or improve the natural environment of the city and to improve the urban environment by preventing pollution and disasters, green areas are created inside the city center. Depending on their function, these green spaces are buffer green spaces installed to prevent pollution, various accidents, and natural disasters, landscape green spaces to improve the urban landscape, and connected green spaces that organically connect parks and rivers in the city and provide leisure and rest functions. are classified as

In general, the composition of green areas maintains the greening area ratio at 50~80% depending on the characteristics of the target area such as exclusive residential areas, maintains the minimum soil depth depending on the type of planting, and maintains a slope of at least 5° with a slope of 10~30° as a standard. It is intended to create more ground. However, in recent years, due to rapid urbanization, the impermeable surface through which rainwater cannot penetrate into the lower part of the ground is increasing, and thus the permeable space is also decreasing. In addition, the natural circulation function of green areas is being degraded, such as creating green areas on artificial ground and draining water through the drainage system during the housing site development project. Moreover, due to the slope formed so that the flow of rainwater does not stagnate in the green area, there is a risk of soil loss and leakage of pollutants in the green area during heavy rain in summer.

In addition, the initial rainwater flowing from the road surface contains significant non-point pollutants, and when it is introduced into the sewage pipe as it is, there is a problem that has a serious effect on environmental pollution. Therefore, technologies that can prevent the concentration of runoff downstream and reduce the movement of non-point pollutants through drainage channels by penetrating rainwater from the point of occurrence are on the rise in recent years.

Stormwater receiving tank having an inlet and an outlet; a cover provided on the upper side of the storm water storage tank to allow rainwater to flow only to the lower side of the storm water tank when the amount of rainwater flowing in from the inlet is less than a predetermined amount, and to divide the rainwater into upper and lower sides when rain increases; a first partition member extending downward from one side of the rainwater accommodating tank and partitioning rainwater flowing from the inlet to the lower side to flow from the bottom; a second partition member extending downward from the other side of the rainwater accommodating tank to partition rainwater flowing from the first partition member to flow from the bottom; pollutant treatment means provided between the first partition member and the second partition member to primarily remove and process pollutants from the passing influent; And it is provided between the second partition member and the rainwater storage tank to filter and adsorb pollutants filled with a filter medium made of any one or more pieces of expanded polypropylene material, activated carbon, loofah, mosquito nets, and ring races to filter and adsorb pollutants There is known a building rainwater treatment device that can reduce various types of water pollution while reducing the burden on sewage treatment by including means.

In addition, Patent Publication No. 1105368 (2012.01.05.) discloses a rainwater transfer channel that is buried under the green ground to face the impervious surface and forms a passageway for rainwater to flow; and a rainwater treatment waterway installed inside the rainwater transfer waterway and purifying rainwater by multi-level layers, wherein the rainwater treatment waterway is provided on the upper part of the rainwater treatment waterway and includes a drain pipe for draining rainwater to the outside and a green surface layer that collects rainwater; a functional treatment layer provided under the green surface layer and removing foreign substances in rainwater; and a water collection layer provided under the functional treatment layer and transporting rainwater collected by a perforated pipe to the outside, thereby forming a sound water circulation system and solving the water shortage phenomenon is known. has been

However, the above-described prior art has a problem in that there is a limitation in terms of water quality in storing and using runoff from the surface, and it is difficult in terms of cost and maintenance to provide a filtration function to solve this problem.

In addition, the conventional technology of inducing or collecting rainwater flowing from a road or sidewalk toward a green area may cause problems in contamination and maintenance of the green area. There was a problem that would lead to

In addition, a technology has been developed that maximizes penetration by installing a belt green protection plate and vertical penetration device between the sidewalk and green area. There was a problem that there was a risk of clogging.
