Description

지반 진동 흡수가 가능한 터널 { A turnel which has absorbing vibration of ground }Tunnel for Absorbing Ground Vibration {A turnel which has absorbing vibration of ground}

본 발명은 지반 진동 흡수가 가능한 터널에 관한 것으로서, 더욱 상세하게는 터널에 작용하는 진동을 흡수하여 터널 라이닝이나 기타 터널 구조물에 크랙이나 손상이 가는 것을 방지하도록 구성한 지반 진동 흡수가 가능한 터널에 관한 것이다.
The present invention relates to a tunnel capable of absorbing ground vibration, and more particularly, to a tunnel capable of absorbing ground vibration configured to absorb vibrations acting on the tunnel to prevent cracking or damage to tunnel lining or other tunnel structures. .

일반적으로, 터널 공사시 터널을 굴찰한 후 굴착된 단면 즉, 암반 및 지반의 붕괴 방지나 터널 입구의 보강 또는 연약한 지반일 경우에 이를 보강하기 위하여 상기 굴착된 단면과 면접되게 지지보를 설치한다.In general, in the case of tunnel construction, the support beam is installed to be interviewed with the excavated cross section to prevent the collapse of the excavated section, that is, the rock and the ground, the reinforcement of the tunnel entrance or the soft ground.

터널은 토압, 수압 등으로 인하여 터널지반의 변위가 발생하게 되는데, 이러한 터널지반의 변위는 심각한 경우 터널 붕괴를 가져와 많은 인명피해를 유발할 수 있으므로 터널이 진동에 견딜 수 있게 지지보를 설치하는 것이 일반적이다.In tunnels, displacement of tunnel ground occurs due to earth pressure and water pressure, and such displacement of tunnel ground can cause tunnel collapse and cause many casualties in severe cases. Therefore, it is common to install support beams so that the tunnel can withstand vibration. .

종래의 경우 지중터널에 지지보를 설치하는 공법은 단순히 터널 굴착면에 밀착될 수 있게 벤딩되어 만곡된 소정크기의 H-빔 등을 일정 간격마다 터널의 진행방향에 직각이 되도록 설치하고, 그 밑바닥에는 굴착터널 바닥에 늘어뜨린 후판 등에 이를 용접하여 연결하는 것 등으로 되어 있다.In the conventional case, the method of installing the support beam in the underground tunnel simply installs a curved H-beam having a predetermined size so as to be in close contact with the tunnel excavation surface at regular intervals so as to be perpendicular to the traveling direction of the tunnel. It is made by welding it to a thick plate or the like hanging on the bottom of an excavation tunnel.

그러나 종래의 H-빔 지지보를 사용하는 공법의 경우 설치시 H-빔 기본 골격이 대형이므로 설치할 때 무겁고 작업인원과 시간이 많이 소요되는 데다, 설사 격자지보를 사용하더라도 작업상 불편하고 시공이 부정확하며 불균일하여 따라서 지지보 설치에 특히 안전상 문제가 발생하고, 안정과 직결되는 작업시간이 많이 들게 되는 단점이 노출되었다. 뿐만 아니라 붕괴 위험이 많은 연약지반에서 격자빔, H-빔등의 지보를 설치할 경우 굴착, 시공 등에 따른 지반진동으로 매우 작업이 위험하여 시공시 큰 문제를 발생시킬 염려가 있었다.
However, in the case of the conventional method using the H-beam support beam, since the H-beam base frame is large in installation, it is heavy and requires a lot of work time and time for installation. As a result of the non-uniformity, there is a particular problem of safety in the installation of the support beam, and the disadvantage of exposing a lot of work time directly related to stability was exposed. In addition, when installing the beams such as lattice beams and H-beams in soft grounds with high risk of collapse, ground vibrations caused by excavation and construction are very dangerous, which may cause serious problems in construction.

본 발명은 전술한 바와 같은 문제를 해결하기 위하여 안출한 것으로서, 터널을 지지할 수 있는 구조물을 편리하게 세울 수 있게 구성한 지반 진동 흡수가 가능한 터널을 제공하고자 하는 목적이 있다.The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a tunnel capable of absorbing ground vibrations configured to conveniently erect a structure capable of supporting the tunnel.

탄력있는 지지강봉이 터널에 작용하는 진동을 흡수하여 터널에 크랙이나 손상이 발생하는 것을 방지하고자 하는 목적이 있다.The elastic support steel bar is intended to absorb the vibrations acting on the tunnel to prevent cracks or damage to the tunnel.

지지강봉의 하단은 앵커판에 의해 기초부와 지중에 견고하게 지지하게 하여 터널의 지지력을 높인 지지구조물을 제공하고자 하는 목적이 있다.The lower end of the support steel bar is to provide a support structure to increase the bearing capacity of the tunnel by supporting the base plate and the ground firmly by the anchor plate.
