터널용 방음방폭장치 {Safety Wall and Door for Tunnel}Soundproof explosion protection device for tunnels {Safety Wall and Door for Tunnel}

본 발명은, 터널용 방음방폭문에 관한 것으로서, 터널작업 중에 발파에 의한 폭음을 효과적으로 방음할 수 있는 터널용 방음방폭문에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof explosion door for tunnels, and more particularly, to a soundproof explosion door for tunnels capable of effectively soundproofing due to blasting during tunnel work.

터널은 도로나 철도가 산이나 언덕 등을 우회하지 않고, 직선으로 통하는 지름길을 건설하기 위해서, 산과 같은 장애물을 관통하여 개설된 통로이다. 일반적으로, 터널을 만들기 위해서는 폭약을 이용하여 발파작업을 하는 것이 필수적이다. 이러한 발파작업 시에는 엄청난 폭음과 분진이 발생하기 때문에 이에 대한 방책으로서, 어느 정도 굴착작업이 진행된 후에는, 터널 입구에 방폭방음장치를 설치하여 폭파작업에 의한 소음을 방음하고 있다. 그리고, 추가하여 터널 내에 개방형 방음벽을 복수로 설치하여 방음효과를 높이기도 한다.A tunnel is a passage opened through an obstacle such as a mountain in order to construct a shortcut that leads to a straight line without a road or railroad bypassing a mountain or a hill. In general, it is essential to blast using explosives to make tunnels. In the case of such blasting work, a tremendous amount of explosion and dust is generated. As a measure for this, after the excavation work is carried out to some extent, the explosion-proof soundproof device is installed at the entrance of the tunnel to prevent noise from the blasting work. In addition, a plurality of open sound barriers may be installed in the tunnel to increase the sound insulation effect.

그런데, 이러한 방폭방음장치는, 터널의 외부에서 차단벽을 설치하기 위해서 이를 지지할 보조 구축물이 필요하고, 터널입구를 폐쇄하기 위해서는 터널의 크기보다 훨씬 거대한 차단벽을 마련하여 설치해야 하므로, 설계에서부터 원자재까지 작업난이도가 높고 경비가 많이 소요되는 단점이 있다. 그리고, 터널의 입구를 완전히 폐쇄시키기 위해서는 추가적인 밀봉작업이 더 필요하다.However, the explosion-proof soundproofing device needs an auxiliary structure to support it in order to install the barrier wall outside the tunnel, and in order to close the tunnel entrance, a barrier wall much larger than the size of the tunnel must be provided and installed. There are disadvantages in that the difficulty of working up to raw materials is high and the expenses are high. Further, additional sealing is needed to completely close the entrance of the tunnel.

따라서, 본 발명의 목적은, 상기의 문제를 해결하고자, 터널 내에 설치가 용이하고 발파작업시 발생하는 폭음을 효과적으로 방음할 수 있는 터널용 방음방폭장치를 제공하는 것이다.Accordingly, an object of the present invention, to solve the above problems, to provide a soundproof explosion-proof device for a tunnel that can be easily installed in the tunnel and effectively soundproof the sound generated during the blasting work.
