초록

본 연구에서는 상수관망 수리해석을 통한 폭염 저감 시설로써의 소화전 활용방안연구를 수행하였다. 소화전 설치 지점을 폭염저감을 위해 개방한다고 가정하고, 지점별 수압에 따른 살수반경을 도출하고 전체 대상구역의 살수면적에 따른 도심지 온도의 저감비율을 살수차운영에 따른 살수면적과 비교하였다. 소화전 개방에 따른 살수면적은, 상수관망 수리해석을 통해 소화전이 설치된 절점에서의 압력값을 도출한후, 압력값에 따른 살수반경 관계식을 통해 산정하였다. 제안된 방법론을 2개의 지역에 적용한 결과, 소화전에 의한 살수방법의 온도저감 효과는 절대적인 살수면적의 차이에 따라, 살수차에 의한 살수방법 대비 낮게 도출될 수 있다는 한계점을 보였다. 그러나, 소화전은 살수차와 달리 물공급양에 대한 상대적 제한이 없고 동일한 지역에 대한 지속적인 분할살수가 가능하므로 일정 구역의 살수면적이 확보될 경우 살수차 대비 상대적으로 효과성 있는 폭염저감 효과를 도출할 수 있을것으로 기대된다.

In this study, a study on how to use a fire hydrant as a heat wave reduction facility through hydraulic analysis of the water supply pipe network was conducted. Assuming that the fire hydrant installation point is open for heat wave reduction, the water pressure at each point was derived. And the reduction rate of the temperature according to the hydrant watering was compared with the watering area according to the operation of the watering truck. The watering area according to the opening of the fire hydrant was calculated by deriving the pressure value at the node where the fire hydrant was installed through hydraulic analysis of the water pipe network, and then using the watering radius relational expression according to the pressure value. As a result of applying the proposed methodology to two real city areas, the temperature reduction effect of the watering method by a fire hydrant can be derived lower than the watering method by a watering truck according to the difference in the absolute watering area. However, unlike a watering truck, a fire hydrant does not have a relative restriction on the amount of water supply and is expected to allows continuous divided spraying of the same area.
