Description
본 발명은 관 구조 터널 건조공법에 관한 것으로, 상세하게는 공사중 시민의 보행이나 상업활동 및 교통의 지장을 주지 않고 안전하게 시공할 수 있도록 하는 관 구조 터널 건조공법에 관한 것이다.The present invention relates to a tubular tunnel construction method, and more particularly, to a tubular tunnel construction method that can be safely installed without disturbing citizens walking, commercial activities and traffic during construction.
일반적으로 터널은 흙이나 바위를 파서 지표면 아래에 만든 공간으로 거의 수평이며 가는 모양의 긴 통로를 말한다. 위쪽에서 재래지반을 남기고 땅속을 파 들어가 만들어진 것이 보통이지만, 지표에서부터 홈모양으로 파고 들어가 그 속에 터널구조물을 만든 다음 다시 묻는 개착공법에 의한 것도 터널에 포함된다. 이 공법은 도시내의 도로 아래에 비교적 얕은 지하철도를 만들 때 이용된다. 오늘날에는 터널의 용도나 양상이 다양화되어 지하발전소용의 대공동, 지하의 자동차주차장이나 각종창고, 지하정유시설이나 지하도로등 흙이나 바위가 붕괴하여 떨어지는 것을 막으면서 땅속을 파서 공간을 만들고, 영구적으로 재래지반을 지지하는 구조물을 건설하는 것도 넓은 뜻으로 터널이라 한다.In general, tunnels are spaces created by digging soil or rock and beneath the surface of the earth. It is usually made by digging up the ground leaving the ground in the upper part, but it is also included in the tunnel by digging into the groove shape from the surface, making the tunnel structure in it, and then burying it again. This technique is used to create a relatively shallow subway road under the roads in the city. Today, the use and aspects of tunnels are diversified, digging into the ground, preventing dirt and rocks from collapsing and falling down, such as large cavities for underground power plants, underground car parking lots, warehouses, underground refineries, and underground roads. Constructing a structure that permanently supports conventional ground is also broadly called a tunnel.
터널의 용도는 철도, 도로 터널 등의 교통용 터널과, 수력발전, 관개 등을 위한 수로 터널 및, 상하수도, 전선로 등의 관로 터널 등이 있다. 이 밖에 지하발전소, 변전소 및 석유류 저장용 지하공동 등도 터널 기술을 적용한 지하건조물로서 터널에 포함시킬 수 있다. 또 터널은 굴착의 대상이 되는 지질에 따라서 암석터널과 토사터널로 나누며, 시공 장소, 시공 방법에 따라 산악터널, 도시터널, 수저터널, 개착터널, 실드터널, 침매터널 등으로 세분된다.The use of the tunnel includes traffic tunnels such as railroads and road tunnels, water tunnels for hydroelectric power generation, irrigation, and pipeline tunnels such as water and sewage and wire lines. In addition, underground power plants, substations, and underground cavities for storing oil can also be included in tunnels as tunnels. Tunnels are divided into rock and earth tunnels according to the geology to be excavated, and they are subdivided into mountain tunnels, urban tunnels, cutlery tunnels, open tunnels, shield tunnels and immersion tunnels depending on the construction site and construction method.
이러한 터널은 여러가지 건조방법으로 개발되어 현재까지 진행되었으나 시민의 보행이나 상업활동 및 교통의 지장을 줄 뿐만 아니라 토압의 변화 및 지반의 거동이 심하게 발생되어 인근 구조물에 악영향을 미치게 되는 문제점이 있었다. 그러므로 시민의 보행이나 상업활동 및 교통 등에서 발생되는 불편함과 피해를 최소하고 안전하게 시공할 수 있는 터널 건조방법의 개발이 지속적으로 요구되었다.These tunnels have been developed by various construction methods, but have been progressed up to now, but not only do people's walking, commercial activities, and traffic problems, but also have a problem that adversely affects nearby structures due to severe earth pressure changes and ground behaviors. Therefore, there has been a continuous demand for the development of tunnel construction methods that can minimize and safely construct inconveniences and damages caused by citizens' walking, commercial activities and traffic.
따라서 본 발명의 주 목적은 흙파기를 최소로 억제하고 루프 및 측벽이 완성된 후 흙파기를 실시하여 지반의 거동 및 토압의 변화를 최소화하여 안전하고 정확하게 도심에서 터널을 건조할 수 있도록 하는 데 있다.Therefore, the main object of the present invention is to minimize the excavation and minimize the change of ground behavior and earth pressure by digging after completion of the roof and sidewall to safely and accurately build the tunnel in the city .
본 발명의 다른 목적은 시민의 보행이나 상업활동 및 교통의 지장을 최소화하여 터널 건조로 인한 주변생활의 불편함을 최소화하도록 하는 데 있다.Another object of the present invention is to minimize the inconvenience of people walking or commercial activities and traffic to minimize the inconvenience of surrounding life due to tunnel construction.
본 발명의 다른 목적은 소음 및 진동을 최소화하여 쾌적한 공사 환경을 제공하는 데 있다.Another object of the present invention is to provide a pleasant construction environment by minimizing noise and vibration.
본 발명의 다른 목적은 터널 시공지역의 주변 구조물에 대하여 안전성을 유지시킬 수 있도록 하는 데 있다.Another object of the present invention is to maintain safety for the surrounding structure of the tunnel construction area.

이상에서 살펴본 바와 같이, 본 발명의 터널 건조공법은 지표에서 수직으로 터널(1)의 시공위치 까지 수직갱을 형성시키는 단계와, 상기 수직갱을 형성시킨 후 수직갱에서 압입수단을 이용하여 메인강관(110)을 터널(1)의 루프 좌우단에서 터널의 길이방향으로 순차로 연결하여 압입하는 단계와, 상기 압입된 좌우 메인강관(110) 중 일측 메인강관(110)에서 타측 메인강관(110)으로 서브강관(120)을 압입하는 단계와, 상기 메인강관(110)에서 하향으로 토류벽을 유지하면서 굴착하여 터널(1)측벽용 공간을 형성시키는 단계와, 상기 메인강관(110)에 하향으로 형성된 공간에 콘크리트를 타설하여 터널(1)측벽을 형성시키는 단계와, 상기 일측 메인강관(110) 서브강관(120) 타측 메인강관(110)에 순차적으로 콘크리트를 채워 경화시키는 단계와, 상기 메인강관(110) 서브강관(120)의 내부 콘크리트 경화후 터널(1)의 내부 흙파기 단계 및, 상기 터널(1) 내부 흙파기 완료후 터널(1) 바닥에 콘크리트를 설치하는 단계로 구성하므로 안전하고 정확하게 도심에서 터널을 건조할 수 있고, 특히 시민의 보행이나 상업활동 및 교통의 흐름에 방해되는 요소가 적어 터널 건조로 인한 주변생활의 불편함을 최소화하며, 또한 소음 및 진동을 최소화하여 쾌적한 공사환경을 제공할 뿐만 아니라 터널의 측벽과 루프를 형성시킨 경화시킨 다음 터널 내부측 흙을 제거하므로 토압의 변화와 지반의 거동이 거의 없고 이로 인하여 터널 시공지역의 주변 구조물에 미치는 악영향이 제거하여 안전하게 시공할 수 있는 효과가 있다.As described above, the tunnel drying method of the present invention comprises the steps of forming a vertical shaft up to the construction position of the tunnel 1 vertically from the ground, and after forming the vertical shaft, the main steel pipe 110 by using a press-fit means in the vertical shaft. The step of connecting the inlet in the longitudinal direction of the tunnel in the right and left ends of the loop of the tunnel (1), and the sub-steel pipe from one of the main steel pipe 110 of the pressed left and right main steel pipe 110 to the other main steel pipe 110 Pressing 120, excavating while maintaining the earth wall downward from the main steel pipe 110 to form a space for the tunnel (1) side wall, concrete in the space formed downward in the main steel pipe (110) Forming the tunnel (1) side wall, and filling concrete in the main steel pipe (110) sub steel pipe (120) and the other main steel pipe (110) in order to harden, and the main steel pipe (110) sub River After the internal concrete hardening of the 120 (120) the internal soil digging step of the tunnel, and after the completion of the internal soil digging tunnel (1) consists of the step of installing concrete on the bottom of the tunnel (1) safely and accurately the tunnel in the city It can be built, and in particular, there are few elements that hinder the walking, commercial activities and traffic flow of citizens, which minimizes the inconvenience of surrounding life due to tunnel construction, and also provides a pleasant construction environment by minimizing noise and vibration. After hardening by forming the tunnel sidewalls and loops, the soil inside the tunnel is removed, so there is little change in earth pressure and ground behavior, thereby removing the adverse effects on the surrounding structures of the tunnel construction area, which makes it safe to construct. .
