Abstract

PURPOSE: A ventilation method of a road tunnel is provided for a simple work of installment and maintenance and for maximizing the ventilation efficiency of the inner part of the road tunnel at a low cost. CONSTITUTION: The tunnel is installed with a device for supplying a ventilation power into the inner part through the entrance of the tunnel in the same moving direction of vehicles with an interval from the entrance of the tunnel. The ventilation force(Pd) through the exit of a cylindrical body(Qo) is bigger than the first ventilation force(Pc) generated from the ventilation unit placed outside of the cylinder body(Qo) as the ventilation(Pc) generated from the ventilation unit(Wo) is increased by the Bernoulli's' law, flowing in the inner part of the cylinder body(Qo) with the adjacent fluids.

이하 첨부된 도면을 참조로 하여 본 발명의 방법 및 장치를 실시예에 따라 상세히 설명한다.Hereinafter, a method and apparatus of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 환기방법은 터널 입구로부터 간격을 두고 차량의 진행방향과 동일하게 상기 터널의 입구를 통해 내부로 송풍력을 부여함으로써 이루어지고, 이를 위한 장치로써 본 발명은 도 1에 도시된 바와같이 상행터널(1)과 하행터널(2)의 각 입구측으로부터 일정 간격을 두고 차량의 진행방향과 동일하게 송풍방향을 갖는 송풍기(3)(4)가 설치되는 것으로서, 이의 작용에 대한 유체역학적인 원리를 도 2a 및 도 2b를 참조로 하여 설명하면 후술한 바와같다.Ventilation method of the present invention is made by applying a blowing force to the inside through the entrance of the tunnel in the same direction as the direction of the vehicle at a distance from the tunnel entrance, the present invention ascending as shown in FIG. The blower (3) (4) having the same blowing direction as the traveling direction of the vehicle is provided at a predetermined distance from each inlet side of the tunnel (1) and descending tunnel (2), the hydrodynamic principle of its action Will be described below with reference to FIGS. 2A and 2B.

즉, 도 2a는 송풍력을 발생하는 송풍원(W)이 일정길이를 갖는 중공의 원통체(Q) 내부에 위치한 것을 나타낸 것이고, 도 2b는 송풍원(WO)이 원통체(QO)의 입구로부터 거리(S)를 두고 위치한 것을 나타낸 것으로서,That is, Fig. 2a is a song will showing a ventilation source (W) is located inside the cylindrical body (Q) of the hollow fiber having a predetermined length for generating the wind, Figure 2b is a cylindrical body (Q O) blowing source (W O) As showing the distance (S) from the entrance of,

결론부터 정리하면 도 2b에 도시된 바와같이 원통체(QO)의 입구로부터 거리(S)를 두고 위치한 송풍원(WO)에서 발생되어 상기 원통체(QO)의 출구를 통해 나오는 송풍력(PD)은, 원통체(Q) 내부에 위치한 송풍원(W)에서 발생되어 상기 원통체(Q)의 출구를 통해 나오는 송풍력(PB)보다 크다. 즉, PB〈 PD가 되는 것이다.CONCLUSIONS From theorem also occurs on the cylindrical body (Q O) at a distance (S) from an inlet in the ventilation source (W O), as shown in 2b transmit wind that has passed through the outlet of the cylindrical body (Q O) P D is greater than the blowing force P B generated at the blowing source W located inside the cylinder Q and exiting through the outlet of the cylinder Q. In other words, P B < P D.

이를 좀더 상세히 설명하면, 도 2a에 도시된 바와같이 원통체(Q) 내부에 위치한 송풍원(W)에서 발생된 송풍력(PA)은 상기 원통체(Q)를 통과하는 동안 원통체(Q) 내부의 측벽부 저항을 받아 와류현상을 일으키게 되고, 이로인해 상기 원통체(Q)의 출구를 통해 나오는 송풍력(PB)은 그 힘이 상당히 약해져 최초 원통체(Q) 내부의 송풍원(W)에서 발생된 송풍력(PA)보다 작게 된다.In more detail, as illustrated in FIG. 2A, the blowing force P A generated from the blowing source W located inside the cylinder Q is passed through the cylindrical body Q. The resistance of the side walls of the inside causes vortices, which causes the blowing force P B exiting from the outlet of the cylindrical body Q to be significantly weakened so that the blowing source inside the initial cylinder Q It becomes smaller than the blowing force P A generated in W).

그러나 도 2b에 도시된 바와같이 원통체(QO)의 입구에서 거리(S)를 두고 위치한 송풍원(WO)에서 발생된 송풍력(PC)은 상기 송풍원(WO)의 주변공기, 즉 주변유체와 함께 원통체(QO) 내부로 유입되어 베르누이 원리에 의한 원통체(QO) 내외의 기압 차이로 인하여 원통체(QO) 외부에서 발생된 송풍력(PC)은 원통체(QO) 내부로 빨려 들어가 빠른 속도로 원통체(QO)를 통과하면서 송풍력(PD)이 증폭됨으로써 상기 원통체(QO)의 출구를 통해 나오는 송풍력(PD)은 원통체(QO)의 외부에 위치한 송풍원(WO)에서 발생된 최초 송풍력(PC)보다 크게 되고, 이로인해 적은 힘으로도 큰 송풍력을 얻을 수 있게 되는 것이다.However, the transmission wind power (P C) occurs in the cylindrical body (Q O) at a distance (S) at the inlet in the ventilation source (W O), as shown in Figure 2b is the air around the portion of the air source (W O) That is, the blowing force (P C ) generated outside the cylindrical body (Q O ) due to the difference in air pressure inside and outside the cylinder (Q O ) by the Bernoulli principle is introduced into the cylindrical body (Q O ) with the surrounding fluid sieve (Q O) sending wind (P D) that has passed through the outlet of the cylindrical body (Q O) by being sucked into the fast as the speed passed through the cylindrical body (Q O) to amplify a transmission wind power (P D) is cylindrical It is larger than the initial blowing force P C generated by the blowing source W O located outside the sieve Q O , and thus, a large blowing force can be obtained with a small force.

따라서 기존의 터널 내부의 천정부에 다수 설치된 젯트팬은 와류현상이 발생되지 않는 140M 이하의 간격유지가 필수적이기 때문에 여러대의 젯트팬이 설치될 수밖에 없는 반면에, 본 발명은 터널 내부에 다수의 젯트팬 또는 기타 환기수단이 없이 터널 입구측의 송풍기만으로도 터널 내부의 오염공기를 보다 신속하게 상기 터널의 출구를 통해 환기시킬 수 있을 뿐만 아니라 화재시에는 충분한 배연 효과를 가지게 되는 것이다.Therefore, the jet fan installed in a plurality of ceilings inside the existing tunnel is required to install a plurality of jet fans in the tunnel because it is necessary to maintain a gap of less than 140M vortex phenomenon does not occur, the present invention is a plurality of jet fans in the tunnel Alternatively, the blower at the entrance of the tunnel without any other ventilation means can quickly vent the polluted air inside the tunnel through the exit of the tunnel and have a sufficient flue effect in case of fire.

상술한 바와같이 본 발명은 터널 내부에 다수의 젯트팬 및 기타 환기수단을 설치함이 없이 터널 입구 측의 송풍기만으로도 상기 터널 내부를 신속하게 환기시킬 수 있을 뿐만 아니라 이로인해 환기설비의 설치 및 유지 관리에 따른 작업이 보다 간편하게 이루어질 수 있는 효과를 갖게 된다. 또한 기존의 젯트팬 및 기타 환기수단의 설치 및 유지 관리에 따른 막대한 비용을 절감할 수 있음은 물론 상기 젯트팬에 의한 환기방식보다 환기효율이 월등히 높아 저렴한 비용으로도 환기효율의 극대화를 기할 수 있는 효과가 있다.As described above, the present invention can not only quickly ventilate the inside of the tunnel by using a blower at the entrance of the tunnel without installing a plurality of jet fans and other ventilation means in the tunnel, and thus, install and maintain the ventilation equipment. Work according to has the effect that can be made more easily. In addition, it is possible to reduce enormous costs associated with the installation and maintenance of the existing jet fan and other ventilation means, and the ventilation efficiency is much higher than the ventilation method by the jet fan, thereby maximizing ventilation efficiency at a low cost. It works.
