Abstract

The present invention relates to a water cycle and efficiency verification system for low impact development (LID) applied to a building. More specifically, various LID technologies to be verified are constructed in concrete boxes that are not permeable to water, and the concrete boxes are divided into a planter box and a street planter. In regards to this, rainwater outflow, which is generated from a rooftop surface or a roof of a building, flows into the planter box to carry out first monitoring, and rainwater outflow, which is additionally generated from a boundary road and the planter box, flows into the street planter to carry out second monitoring. Accordingly, the LID technologies, which manage rainwater outflow generated from a rooftop or a roof of a building, and a boundary road around a building, enable rainwater outflow to be more accurately and efficiently verified and managed on a real scale.

Description

{LOW IMPACT DEVELOPMENT (LID) HYDRAULIC CYCLE IN BUILDING SITE AND ITS EFFICIENCY VERIFICATION SYSTEM}

The present invention relates to a real-scale verification system for LID (Low Impact Development) technology that manages stormwater runoffs generated from roofs, roofs, and structures around buildings, among various impervious surfaces.

Various environmental problems have arisen due to the increase of runoff water due to unplanned area increase due to unexplored urban development and destruction of forests, and destruction of water circulation and heat cycle.

According to the Ministry of Environment 's press release, the domestic impervious area is the main cause of water circulation and thermal cyclic destruction. Impervious area rate is 7.9% in the national average and 22.4% excluding water and forest. According to the city, Bucheon city is the highest city with 61.7%, followed by Seoul with 54.4% and Mokpo with 46.3%.

Generally, it is known that watersheds with an impervious area of more than 25% are significantly deteriorating in health, and interest in LID to suppress the expansion of impervious surfaces is increasing.

The LID technique simulates the hydrological cycle before development and minimizes the impact of development and improves the water circulation structure to prevent flood damage caused by heavy rainfall due to rapid urbanization and climate change. In recent years, various LID technologies have been developed and applied for impervious surface management in urban areas. However, the management of storm drainage due to application without consideration of local and environmental characteristics It has difficulties.

On the other hand, various LID technologies have been developed and applied for impervious surface management in the city. Especially, it is possible to apply various LID facilities connected with buildings, and research and technology are continuously being developed. As for the general flow of the effluent from the building, the effluent from the rooftop or the roof is drained directly to the effluent through the vertical trough.

However, the above system can cause flooding of the city due to the load of the excellent pipe during the heavy rainfall such as in the summer, and the rapid drainage prevents the inflow of water into the green area in the city, resulting in severe drought.

Therefore, in order to solve this problem, as shown in Patent Documents 1 to 3, a vegetation-based LID facility such as a rainwater garden, an infiltration facility such as a pavement pavement, a rainwater utilization facility capable of reusing rainwater, Technology development and application are being implemented.

However, the above-mentioned prior arts have little effect on the management of storm drainage due to application without consideration of local and environmental characteristics. In addition, there is a limit to the management of storm water through single installation of LID facilities such as vegetation infrastructure, permeable pavement, rainwater utilization facilities, and technical verification standards and verification facilities for existing technologies or development technologies are required. However, It is difficult to apply proper LID because of the lack of regulations and facilities. In particular, there is no real-scale verification system for LID technology that manages stormwater runoffs on roofs, roofs, and structures around buildings.
