본 발명은 파형강판을 이용한 터널시공방법 및 터널에 관한 것으로서 특히, 전후 플랜지가 내측방향으로 절곡되어지도록 형성되어 벤딩된 파형강판을 굴착된 터널의 내부에서 조립하여 설치하고, 파형강판의 외측면과 굴착된 터널의 내면 사이에 콘크리트를 타설하여 시공됨으로써, 시공작업의 효율을 높이도록 하고, 아울러 기존에 시공된 터널의 특정한 부분을 더 보강할 수 있도록 한 것이다.The present invention relates to a tunnel construction method and a tunnel using a corrugated steel sheet, and in particular, the bent corrugated steel sheet is formed to be bent inward and backward to be assembled and installed inside the excavated tunnel, and the outer surface of the corrugated steel sheet By laying concrete between the inner surfaces of the excavated tunnel, the construction work is to increase the efficiency of the construction work, and also to reinforce specific parts of the existing tunnel.

일반적으로 소정 두께와 넓이를 갖는 평판형태의 강판은 이를 여러 형태로 절곡 및 탄성 변형시키고, 이를 축방향으로 연속되는 형태로 시공함으로써 터널, 지하통로 및 용수, 배수로 등 여러 용도로 사용되어지고 있다.In general, a plate-shaped steel sheet having a predetermined thickness and width is bent and elastically deformed in various forms, and is used in various applications such as tunnels, underground passages, water, and drainage channels by constructing them in a continuous form in the axial direction.

이러한 강판은 구조물의 크기가 작을 경우 벤딩된 하나의 강판을 이용하며 크기가 커질 경우 벤딩 공정에서 벤딩율을 크게함과 동시에 파형강판을 여러장으로 나뉘어 제조하고, 제조된 파형강판을 여러장을 겹치거나 볼팅 등의 별도의 조립공정을 통해 설치되어진다.When the size of the structure is small, such a steel plate uses one bent steel plate, and when the size is large, the bending rate is increased in the bending process, and the corrugated steel sheet is divided into several sheets, and the manufactured corrugated steel sheets are overlapped. Or through a separate assembly process such as bolting.

또한, 얇은 두께의 강판에 여러 방향으로 부터 작용하는 하중을 분산시켜 내하력을 크게 하기 위하여 통상 평평한 강판에 주름이 성형된 파형강판을 사용하게 된다.In addition, in order to increase the load capacity by distributing the load acting in various directions to the thin steel sheet, a corrugated steel sheet in which wrinkles are formed on a flat steel sheet is usually used.

이와 같은 파형강판을 이용하여 터널 구조물을 시공할 경우, 우선 터널의 형태를 갖도록 굴착한 후 굴착된 지반의 양측을 일정한 깊이로 굴착하여 기초지반을 다지고 거푸집과 철근을 배근하고, 이어 앵커와 채널을 설치한 후 콘크리트 타설하여 양생시키고, 거푸집을 해체한다.When constructing a tunnel structure using such corrugated steel sheet, first excavate to have the form of tunnel, then excavate both sides of the excavated ground to a certain depth to lay the foundation ground and reinforce the formwork and reinforcing bars, and then anchor and channel After installation, the concrete is poured and cured, and the formwork is dismantled.

거푸집이 해체된 채널에 파형강판의 하부가 직각이 되도록 한 후 볼트와 너 트로 고정시키고, 채널에 하부가 결합된 파형강판 사이에 다른 파형강판을 동일한 방법으로 결합시키는 볼팅작업을 반복하여 굴착된 터널 내부에 파형강판을 설치하고, 파형강판의 외면과 굴착된 굴착면 사이의 공간에 콘크리트를 타성하여 양생시키는 것으로 터널 구조물을 얻을 수 있게 된다.Tunnel is excavated by repeating the bolting work to make the lower part of corrugated steel plate at right angle to the channel where the formwork is dismantled, and then fix it with bolts and nuts, By installing the corrugated steel sheet inside, the tunnel structure can be obtained by inerting and curing concrete in the space between the outer surface of the corrugated steel sheet and the excavated excavation surface.

As the work space is narrowed by the flange formed to have a shape protruding toward the inner surface of the excavated tunnel, there was a main reason that the smooth work cannot be performed.
