교량의 케이블의 화재를 방지하는 수관 장치 및 화재 방지 방법Water pipe device and fire prevention method to prevent fire of cable of bridge

본 발명은 화재 방지 기술로서, 보다 구체적으로, 교량 케이블의 화재를 조기에 진압하기 위해 화재로 인해 케이블이 끊어지기 전에 먼저 터져 방출된 소화액으로 케이블의 화재를 방지하는 수관 장치 및 화재 방지 방법에 관한 것이다.The present invention relates to a fire protection technique, and more particularly, to a water pipe device and a fire protection method for preventing fire of a cable with a fire extinguishing liquid that is first blown out before the cable is broken due to the fire in order to extinguish the fire of the bridge cable early. will be.
교량에는 케이블이 설치된다. 예를 들어, 사장교, 현수교 등의 교량에는 케이블이 교량의 구조물로서 설치된다. 여기서, 케이블의 수명을 보호하기 위해 케이블은 보호관에 내장된다.The bridge is equipped with cables. For example, cables are installed in bridges such as cable-stayed bridges and suspension bridges as bridge structures. Here, the cable is embedded in a protective tube to protect the life of the cable.
여기서, 케이블의 보호관은 HDPE(고밀도 폴리에틸렌, High Density Polyethylene)와 같은 가연성 재질이라서 화재에 취약하다. 2015.12.03.에 발생된 서해안 고속도로 하행선 서해대교의 화재 사고의 경우, 교량의 주탑 꼭대기(높이 약 100m 지점)에서 낙뢰를 맞음으로써 화재가 발생하고, 화재로 인해 주탑에 연결된 케이블이 끊어져 낙하함으로써 현장에서 화재 진압 중인 소방 공무원 4명이 사상을 입은 바 있다.Here, the protective tube of the cable is a flammable material such as HDPE (High Density Polyethylene), so it is vulnerable to fire. In the case of a fire accident on the west coast bridge of the west coast highway descending line that occurred on Dec. 3, 2015, a fire occurred by hitting the top of the bridge's pylon (about 100m in height), and the fire caused the cable connected to the pylon to be disconnected and dropped. Four firefighters who were battling in Iraq were killed.
교량의 케이블에 대한 화재의 사례를 분석해 보면, 대형 참사로 번질 가능성의 위험이 있다. 케이블 화재가 발생하고, 화재가 번짐에 따라 케이블이 절단되고, 절단된 케이블로 인해 교량의 상판 지지력이 줄어들고, 줄어든 지지력에 의해 교량이 붕괴되는 대형 참사가 야기될 수 있다. 교량의 상판을 지지하는 케이블이 2개 이상 절단되는 경우 하중 분산의 불균형이 발생하여 상판의 전체 붕괴가 우려된다. 이미, 성수대교의 사례를 보더라도 교량 붕괴시 엄청난 인명과 재산의 손해가 발생됨을 익히 알고 있다.Analyzing the case of a fire on a bridge's cable, there is a risk of a catastrophic event. A cable fire may occur, the cable may be cut as the fire spreads, and the cut cable may reduce the top plate bearing capacity of the bridge and cause a catastrophic disaster in which the bridge collapses due to the reduced bearing force. If two or more cables supporting the bridge's top plate are cut off, an unbalance of load distribution occurs and the overall collapse of the top plate is concerned. Even in the case of Seongsu Bridge, we already know that the collapse of the bridge causes tremendous loss of life and property.
교량에서 케이블의 화재가 발생되는 것은 낙뢰, 유조차 전복 등 다양한 원인이 있을 수 있는데 화재의 발생을 막는 것은 거의 불가능하다. 때문에, 케이블 화재는 케이블이 끊어지기 전에 조기에 진압하는 것이 무엇보다도 중요하다.Cable fires on bridges can have a variety of causes, such as lightning strikes and oil overturns. It is almost impossible to prevent fires. Therefore, it is most important that the cable fire is put out early before the cable breaks.

상기에서, 수관 장치(100)가 케이블에 설치되면, 케이블의 화재에 대해 초기 화재 진압이 가능하므로 골든 타임이 확보된다. 케이블에 수관 장치(100)가 나선형으로 설치됨으로써 비, 바람에 의한 흔들림의 지지력이 증가되어 케이블 구조 안정성에 따른 케이블의 과진동이 방지된다. 수관 설치 공사 및 관리에 의한 일자리 창출이 기대된다. 또한, 수관 설치 비용은 화재에 의한 사회적 손실 비용과 비교할 때, 약 2.2%로써 경제적 및 효율적인 화재 방지 비용이다.In the above, if the water pipe apparatus 100 is installed in the cable, the golden fire is secured since initial fire suppression is possible for the fire of the cable. Since the water pipe device 100 is spirally installed on the cable, the bearing force of the shaking caused by rain and wind is increased to prevent over-vibration of the cable due to the cable structure stability. Job creation by water pipe installation construction and management is expected. In addition, the cost of installing the water pipe is about 2.2%, which is economical and efficient fire prevention cost, compared with the cost of social loss due to fire.
도 2는 도 1의 수관 장치(100)가 설치되는 교량(200)의 케이블(220)의 예시도이다.FIG. 2 is an exemplary view of the cable 220 of the bridge 200 in which the water pipe apparatus 100 of FIG. 1 is installed.
상기 교량(200)은 케이블(220)의 장력에 의해 지지되는 사장교, 현수교 등에 해당된다. 참고로, 대한민국의 사장교 및 현수교는 전국 45개소에 이르며, 교량 길이가 총 53km에 다다른다. 교량(200)은 일정 간격마다 설치된 주탑(210)을 가진다. 각각의 주탑(210)을 기준으로 케이블(220)이 설치되고, 설치된 케이블(220)의 장력에 의해 바닥면에 해당되는 상판(230)을 들어올리는 지지 역할을 한다. 즉, 주탑(210)과 연결된 케이블(220)을 통해 상판(230)의 하중이 고르게 분산되면서 상판(230)이 상방향으로 지지될 수 있다.The bridge 200 corresponds to a cable-stayed bridge, a suspension bridge, and the like, supported by the tension of the cable 220. For reference, there are 45 cable-stayed bridges and suspension bridges in Korea, and the length of the bridge reaches 53km in total. Bridge 200 has a pylon 210 installed at regular intervals. The cable 220 is installed based on each main tower 210, and serves to support the lifting of the upper plate 230 corresponding to the bottom surface by the tension of the installed cable 220. That is, the top plate 230 may be supported upward while the load of the top plate 230 is evenly distributed through the cable 220 connected to the main tower 210.
도 3은 도 2의 교량(200)의 케이블(220)의 단면도이다.3 is a cross-sectional view of the cable 220 of the bridge 200 of FIG.
상기 케이블(220)은 파이프 형의 보호관(321)의 내부에 케이블 철심(323)이 수용되어 형성된다. 보호관(321)은 철심(323)을 보호하고 수명을 연장시키는 역할을 한다. 보호관(321)의 내측은 철심(323)과의 마찰력을 줄이기 위해 왁스(325)(petroleum wax)가 충전된다. The cable 220 is formed by receiving a cable iron core 323 inside the pipe-shaped protective tube 321. The protective tube 321 serves to protect the iron core 323 and extend the life. The inner side of the protective tube 321 is filled with a wax 325 (petroleum wax) to reduce friction with the iron core 323.
케이블(220)에 화재가 발생하는 것은, 보호관(321)의 가연성의 고밀도 폴리에틸렌 재질인 HDPE에 기인한다. 즉, 가연성의 재질로 구성된 보호관(321)이 오히려 화재를 번지게 하는 역할을 하여 화재로 인해 케이블(220)이 단선되는 것이다. 나아가, 내부에 충전된 왁스(325) 또한 화재의 진화를 어렵게 하고 화재가 지속되는 것을 방조한다.The occurrence of fire in the cable 220 is caused by the HDPE which is a flammable high density polyethylene material of the protective tube 321. That is, the protective tube 321 made of a combustible material rather serves to spread the fire is to disconnect the cable 220 due to the fire. Furthermore, the wax 325 filled therein also makes it difficult to extinguish the fire and help the fire last.
도 4는 도 2의 교량(200)의 케이블(220)에 설치되는 수관 장치(100)의 예시도이다.4 is an exemplary view of a water pipe apparatus 100 installed on the cable 220 of the bridge 200 of FIG.
케이블(220)의 상단은 주축(210)에 고정되고, 타단은 지면의 케이블 고정부(210)에 고정된다. 상기 수관 장치(100)의 수관(110)은 케이블(220)의 보호관(321)의 외면을 따라 나선형으로 감싸듯이 설치된다. 설치된 수관(110) 및 보호관(321)의 연장선에서 일정 간격마다 밴드(120)가 설치되고, 각각의 밴드(120)가 수관(110)과 보호관(321)을 조여서 고정시키는 역할을 한다.The upper end of the cable 220 is fixed to the main shaft 210, the other end is fixed to the cable fixing portion 210 of the ground. The water pipe 110 of the water pipe device 100 is installed as a spiral wrap around the outer surface of the protective pipe 321 of the cable 220. Bands 120 are installed at predetermined intervals from the extension lines of the water pipe 110 and the protection pipe 321 installed, and each band 120 serves to tighten the water pipe 110 and the protection pipe 321 to be fixed.
여기서, 수관(110)의 최상단(401)에는 깔대기 형상의 소화액의 유입구가 형성된다. 유입구를 통해 채워지는 소화액은 물 및 기타 소화 물질일 수 있다. 또한, 수관(11)의 최하단(402)은 내부에 소화액이 수용되도록 폐쇄된다. 즉, 수관(11)은 유입구를 통해 물이 공급되어 물 주머니 역할을 한다.Here, the inlet of the funnel-shaped fire extinguishing liquid is formed at the top end 401 of the water pipe 110. The digestive fluid filled through the inlet may be water and other extinguishing agents. In addition, the bottom end 402 of the water pipe 11 is closed to accommodate the digestive fluid. That is, the water pipe 11 is supplied with water through the inlet port serves as a water bag.
또한, 보호관(321)은 인화점이 300도 이상인 반면에 수관(110)의 인화점이 85도 이상이 되기 때문에, 화재시 인화점이 상대적으로 낮은 수관(110)이 상승된 온도에 먼저 영향을 받고 터지게 된다. 수관(110)이 터짐에 따라 내부 수용된 물은 보호관(321)의 외면을 따라 흘러 화재를 방지한다. 이미 화재가 발생된 경우 화재를 진압하는데 물이 이용된다. 또한, 물에 적셔진 보호관(321)은 온도가 낮아지고 비가연성 재질로 변하여 화재를 방지하는 역할을 한다.In addition, since the protection pipe 321 has a flash point of more than 300 degrees, the flash point of the water pipe 110 is more than 85 degrees, and in the event of fire, the water pipe 110 having a relatively low flash point is first affected by an elevated temperature. . As the water pipe 110 bursts, the water accommodated inside flows along the outer surface of the protection pipe 321 to prevent fire. If a fire already occurs, water is used to extinguish the fire. In addition, the protection tube 321 soaked in water lowers the temperature and changes to a non-combustible material serves to prevent fire.
도 5는 도 4의 A가 확대된 수관(110)의 최상단(401)에 형성된 유입구(500) 의 예시도이다.FIG. 5 is an exemplary view of an inlet 500 formed at the top 401 of the water pipe 110 in which A of FIG. 4 is enlarged.
최상단(401)에 깔대기 모양으로 형성된 유입구(500)는 물이 유입되는 역할을 하면서 동시에 우천시 우수를 모아 수관(110) 내부로 유입되도록 한다. 즉, 우천시마다 우수는 유입구(500)를 통해 수관(110) 내부의 소화액을 보충한다. 소화액으로써 물이 경제성을 갖도록 하는데, 수관(110) 내부로 유입된 우수가 자연적으로 소화액을 보충할 수 있어 관리 비용의 경제성까지 갖도록 한다.The inlet 500 formed in the shape of a funnel at the top end 401 serves to inflow of water and at the same time collects rainwater during rainy weather and flows into the water pipe 110. That is, every rainy season replenishes the digestive fluid inside the water pipe 110 through the inlet 500. As the extinguishing liquid, the water has economical efficiency, and the rainwater introduced into the water pipe 110 may naturally replenish the extinguishing liquid, thus maintaining the economical cost of management.
도 6은 본 발명의 일 실시예에 따른 수관 장치(100)의 화재 방지 방법의 개략적인 순서도이다.6 is a schematic flowchart of a fire protection method of the water pipe device 100 according to an embodiment of the present invention.
수관 장치(100)가 교량(200)의 케이블(220)에 설치된다. 설치가 시작되면, 수관(110)이 케이블(220)의 보호관(321)의 외면을 나선형으로 감싸도록 설치된다(S611).The water pipe device 100 is installed in the cable 220 of the bridge 200. When the installation starts, the water pipe 110 is installed to spirally wrap the outer surface of the protective pipe 321 of the cable 220 (S611).
여기서, 지면으로부터 가장 높은 곳에 위치하는 수관(110)의 최상단(401)은 소화액이 주입되기 위한 깔대기 형상의 유입구(500)를 가진다. 또한, 수관(110)은 소화액이 내부에 수용되도록 지면과 가장 가까운 최하단(402)은 폐쇄되어 있다.Here, the top end 401 of the water pipe 110 located at the highest position from the ground has a funnel-shaped inlet 500 for injecting digestive fluid. In addition, the water pipe 110, the bottom end 402 closest to the ground is closed so that the digestive fluid is received therein.
수관(110)이 설치되면, 수관(110)과 케이블(220)의 접한 관로의 일정 간격마다 고정력을 위해 탄성 재질의 밴드(120)가 설치되고(S613), 밴드(120)는 조이는 역할(수축 작용)로 수관(110)을 케이블(220)에 고정시킨다.When the water pipe 110 is installed, a band 120 of elastic material is installed for a fixed force at a predetermined interval between the water pipe 110 and the cable 220 in contact with each other (S613), and the band 120 is tightened (shrinkage) The water pipe 110 to the cable 220.
초기 설치시 수관 장치(100)가 케이블(220)에 고정되면, 유입구(500)를 통해 수관(110) 내부로 물이 소화액으로서 주입되고, 주입된 소화액이 내부에 수용된다(S615).When the water pipe apparatus 100 is fixed to the cable 220 during the initial installation, water is injected into the water pipe 110 through the inlet 500 as a digestive liquid, and the injected digestive liquid is accommodated therein (S615).
초기 설치 이후, 우천시마다 유입구(500)가 우수를 모아서 내부로 유입하는 역할을 하여 우수가 수관(110)의 소화액으로써 보충된다(S631). 수관(110)은 상시 소화액이 채워질 것이 요구된다.After the initial installation, the rain inlet 500 serves to collect rainwater and flow into the rainwater, and the rainwater is replenished with a digestive fluid of the water pipe 110 (S631). The water pipe 110 is required to be filled with digestive fluids at all times.
또한, 동절기가 되면, 수관(110)이 동파되는 것을 방지하기 위해 유입구(500)를 통해 부동액이 수관(110) 내부에 주입된다(S633).In addition, when the winter season, the antifreeze is injected into the water pipe 110 through the inlet 500 to prevent the water pipe 110 from freezing (S633).
이후, 화재가 발생하면, 온도 상승에 의해 수관(110)의 인화점 85도에 다다르면, 수관(110)이 터져서 내부의 소화액이 방출되고, 방출된 소화액은 케이블을(220)을 적셔서 화재를 방지한다(S651). 참고로, 케이블(220)의 보호관(321)의 인화점은 300도로서 화재시 인화점이 낮은 수관(110)이 먼저 터지게 된다.Then, when a fire occurs, when the flash point of the water pipe 110 reaches 85 degrees due to the temperature rise, the water pipe 110 is blown out and the extinguishing liquid is discharged, and the released extinguishing liquid wets the cable 220 to prevent fire. (S651). For reference, the flash point of the protection tube 321 of the cable 220 is 300 degrees, the water pipe 110 having a low flash point in case of fire is first blown.
