본 발명은 터널굴착부의 토사를 미리 파내지 않고 먼저 지중에 터널형성용 구조물을 설치하여 사전에 충분히 응력에 견디도록 한다음 구조물 내측을 굴착하여 지하터널을 형성하도록 하는 지하터널 형성용 구조물 설치방법 및 그 구조에 관한 것으로, 더욱 상세하게는 지하터널 구조물을 경제적이고 안전하며 정확하게 설치 할 수 있도록 하며, 구조물의 설치시는 물론 설치후에도 그 구조물이 구조적으로 매우 견고하여 터널굴착 작업을 안정적으로 할 수 있도록 함은 물론 터널 완성 후에는 그 수명이 장구하도록 한 것이다.The present invention is to install a structure for forming tunnels in the ground without digging out the soil of the tunnel excavation in advance to sufficiently endure the stress in advance, and then to excavate the inside of the structure to form an underground tunnel forming structure and It relates to the structure, and more specifically, it is possible to install the underground tunnel structure economically, safely and accurately, and to make the tunnel excavation work stable as the structure is very solid structurally after installation and even after installation. Of course, after the tunnel is completed, its life is long.
일반적으로 터널을 형성하기 위해서는 반드시 터널외부로 부터 발생하는 응력에 견딜 수 있도록 터널구조물이 설치되는바, 이와같은 터널구조물을 설치하기 위한 종래의 터널구조물 설치방법의 일실시예를 설명하면 다음과 같다.In general, in order to form a tunnel, a tunnel structure is installed so as to withstand the stress generated from the outside of the tunnel. Hereinafter, an embodiment of a conventional tunnel structure installation method for installing such a tunnel structure will be described. .
먼저 도1에 도시된 바와같이 지중에 소정간격으로 대구경의 강관(10)을 터널과 같은 형태로 압입하여 강관(10)내부 및 강관(10) 외면을 그라우팅한 후에 강관(10)내측 터널면을 일정깊이로 굴착한다음 여러개로된 지보공(100)을 다수개의 볼트로 연결하여서된 지보공(100)을 구조물 내측전체에 걸쳐 설치한다음 그내측으로 콘크리트(60)를 타설하여 가시설공사를 완료하는 방법을 수차례 반복하면서 지하터널 형성용 구조물을 설치하였던바, 이와같은 일실시예에 의한 종래의 방법은 물론 그 밖의 터널구조물 설치방법들은 거의 모두가 공통적으로 일정깊이로 미리터널굴착을 한다음 가시설공사를 완료하고 지하터널 구조물을 설치하는 공법을 반복하는 방법들이어서,First, as shown in FIG. 1, a large diameter steel pipe 10 is press-fitted into a tunnel-like shape at a predetermined interval in the ground to grout the inside of the steel pipe 10 and the outer surface of the steel pipe 10, and then the inner tunnel surface of the steel pipe 10. Excavation to a certain depth and then install the jibo ball (100) by connecting a plurality of jibo ball 100 with a plurality of bolts throughout the inside of the structure and then poured concrete (60) to the inside to complete the construction work The structure for forming the underground tunnel was repeated several times, and the conventional method according to one embodiment as well as the other tunnel structure installation methods are almost all common tunneling in advance to a predetermined depth. How to complete the process and repeat the process of installing underground tunnel structures,
첫째로는 먼저 터널굴착을 선행한 후 가시설공사를 진행하여야 하므로 매번 가시설공사를 하여야 하는 번거로움이 있었으며, 안전사고의 문제점을 안고 있었다.First of all, there was a hassle of having to construct a temporary facility every time because the construction of a temporary facility should be carried out before the tunnel excavation, and there was a problem of a safety accident.
둘째로는 가시설공사를 진행하기 위해서는 먼저 터널굴착후 여러개로된 지보공(100)을 다수개의 볼트로 연결하여서 설치하여야 하는데 이 또한 작업이 매우 까다롭고 힘들어 많은 인력이 소요되고 공정이 길어 비경제적이며, 가시설의 작업으로 시공상의 작업이 매우 더딘 문제점이 있었다.Secondly, in order to proceed with the temporary construction, first, after the tunnel excavation, several jiborongs (100) must be installed by connecting them with a plurality of bolts. There was a problem that the construction work was very slow due to the work of the temporary facility.
셋째로는 선행되는 굴착작업시 너무 깊이 굴착을 하면 지반이 약할 경우 굴착도중에는 물론이고 굴착후 가시설공사중에 지반 또는 암반등이 붕괴하거나 낙하할 염려가 매우 높아서 항상 안전사고의 발생위험이 많아 항상 적은 깊이로만 굴착을 선행하여야 하므로 작업이 연관성이 결여된 문제점이 있었다.Thirdly, if the excavation is too deep during the preceding excavation work, if the ground is weak, it is very likely that the ground or rock will collapse or fall during the excavation construction as well as during the temporary construction work. Since the excavation was to be preceded only by the operation, there was a problem that the work was not related.
결국, 상기와 같이 종래의 터널구조물설치공법에 의하면 미리 터널굴착작업을선행한 후 가시설공사를 설치하고 나면 기설치된 가시설물이 간섭을 줌으로 공기가 길며, 위험하고 터널구조물을 설치할때 최소단위로 반복되는 방법이어서 많은 인력과 장비 및 자재가 소요되어 작업이 비능률적이고 비 경제적이며, 터널구조물의 지구력의 취약점때문에 항상 터널붕괴 및 안전사고의 발생위험으로 부터 벗어날 수 가 없는등의 여러가지 문제점을 않고 있었다.As a result, according to the conventional tunnel structure installation method as described above, after installing the temporary construction work after the tunnel excavation work in advance, the installed temporary facilities interfere with the air, which is long, dangerous, and at the minimum unit when installing the tunnel structure. As it is a repetitive method, it requires a lot of manpower, equipment and materials, which makes the work inefficient and inexpensive, and because of the weakness of the endurance of the tunnel structure, it was not always able to escape from the risk of tunnel collapse and safety accidents. .
이에, 상기한 방법들에 의한 터널 굴착시의 결점을 배제하여 작업상 위험성이 없고, 작업을 일관되게 능률적으로 할 수 있도록 미리 땅을 굴착하지 않은 상태에서 일시에 연속적인 굴착 공사만을 할 수 있도록 지하터널 형성용 구조물 설치방법이 안출되었는데, 이는 첨부도면 도2에 도시된 바와같이, 1.5m~2m의 대구경 강관을 터널시공예정면을 따라 지중에 압입한 다음, 상기 강관(10)과 강관(10)사이에 소구경 파이프(110)를 강관(10)과 나란히 수평으로 설치하고, 상기 양 강관(10)에 걸친 상부를 통상의 시멘트, 규산, 폴리우레탄과 같은 것으로 감싸거나 동결공법으로 감싸서 토사 붕괴 방지용 그라우팅부(70)를 형성한다음, 상기 강관들 측면의 대향되는 일정길이의 곡면 부위를 절개하여 상호 개방된 절개부를 형성하고 절개된 절개부의 상,하 양끝을 철판(120)으로 용접연결한 후 강간지주(strut)(140)를 설치하여 지지토록 하여서, 상기 강관 내부 하측을 스티로폴로 채운 후에 나머지 공간에 콘크리트로 타설하는 방법으로 지하터널 형성용 구조물을 설치하도록 한 것이다.Therefore, there is no risk of work by excluding the defects in tunnel excavation by the above methods, and only underground excavation work can be done at a time without excavating the ground so that work can be performed efficiently and consistently. A method for installing a structure for forming a tunnel was devised. As shown in FIG. 2, a large diameter steel pipe of 1.5 m to 2 m was press-fitted into the ground along the tunnel construction plan, and then the steel pipe 10 and the steel pipe 10 were inserted. The small diameter pipe 110 is installed horizontally in parallel with the steel pipe 10, and the upper portion over the both steel pipes 10 is wrapped with a cement, silicic acid, polyurethane or the like, or wrapped with a freezing method to collapse the soil. After forming the prevention grouting portion 70, by cutting the curved portion of the opposite length of the side of the steel pipe to form an incision open to each other and the upper and lower ends of the cut incision to the iron plate (1) 20) after the welding connection to install the rape column (strut) (140) to support, by filling the lower side of the inside of the steel pipe with styropol to install the structure for underground tunnel formation by placing concrete in the remaining space. .
그러나, 이와같은 방법은 첫째로는 강관과 강관사이마다 길이가 긴 소구경파이프를 전부 강제 압입하여 설치하여야 하므로, 길이가 길땐 파이프의 선도관 및 조정장치가 없어 방향성 및 직진도가 결여되어 설치가 곤란하고, 강관과 강관 사이 폭이 넓어지면 소구경 강관으로 토사방지가 불가하여 자재비 및 시공비가 많이 소요되고, 돌이 있거나 토층이 상이할 시 방향이 틀어지는등 직진도가 불확실하며, 호박돌이나 그 이상의 암석이 산재해 있을시 시공이 매우 어려우며, 강관내부에 충진공법을 병행 안할시 부식되어 취약하게 되여, 지하수 및 토류유실을 방지하기가 어렵게 되며, 파이프 내부를 충진 할시 비 경제적이다.However, in such a method, first, all long diameter pipes must be forcedly installed between the steel pipes and the steel pipes. Therefore, when the length is long, the pipes and the adjustment device of the pipes are lacking, which leads to lack of directivity and straightness. Difficult, wider width between steel and steel pipes, small diameter steel pipes are not possible to prevent earth and sand, it takes a lot of material and construction cost, and the straightness is uncertain, such as the direction is changed when there is a stone or the soil is different, amber stone or more rock When scattered, the construction is very difficult, and when the filling method is not combined with the steel pipe, it becomes vulnerable to corrosion, making it difficult to prevent groundwater and earth leakage, and it is uneconomical when filling the pipe.
둘째로는 상기 강관(10)들 측면의 대향되는 일정길이의 곡면 부위를 절개하여 상호 개방된 절개부를 형성할대 이미 상재 토압에 의해 붕괴의 우려가 있고 절개된 절개부의 상,하 양끝을 철판(120)으로 용접연결한 후 강간지주(strut)(140)를 설치하여야 하는데 이때 하부철판으로 토압이 전달되므로 보강판을 따로 설치하여 작업이 복잡하고, 별도의 철판자재가 필요하여 자재비가 과다하게 들어가 비 경제적이며, 외부응력에 견디는 힘이 약하여 사전 필요한 조치가 없을 시 구조적으로 불안전하였다.Secondly, when cutting the curved portions of a predetermined length of the sides of the steel pipes (10) to form the mutually open incisions, there is a fear of collapse by the earth pressure, and the upper and lower ends of the incisions are cut out. After the welding connection to 120), the rape column (strut) (140) should be installed. At this time, the earth pressure is transferred to the lower steel plate, so that the work is complicated by installing the reinforcement plate separately, and additional steel plate material is required, so the material cost is excessively increased. It was uneconomical and weak in external stress, structurally unstable in the absence of necessary measures.
셋째로는 상기 강관 내부 하측에 거푸집용으로 스티로폴로 채우는 작업에 있어서, 자재비가 과다하게 들며, 시공물량이 적을 경우 스치로폴의 구매가 어려위 관에 맞추어 스티로폴을 가공하거나 주문생산하여야 하고, 강관의 치수가 달라지면 치수에 맞는 스치로폴을 재 구입하여야 하므로 불편하였다.Thirdly, in filling the styropol for formwork in the lower side of the steel pipe, the material cost is excessive, and if the construction volume is small, it is difficult to purchase Styropol, and the styropol must be processed or made to order according to the pipe, and the dimensions of the steel pipe Was different, it was inconvenient because you have to repurchase Schiropol according to the dimensions.
그리고, 공사완료후 스티로폴의 폐기물은 환경에 오염을 주며 처리도 곤란하였다.After completion of the construction, Styropol's wastes were contaminated with the environment and difficult to dispose of.
넷째로는 강관내부가 무근콘크리트로 되어 있어 외부응력에 약하고 구조적으로 해석이 어렵고 또한, 보강공법을 써야 하므로 추가비용이 많이 발생되어 비경제적이고 위험요소가 산재해 있었다.Fourth, the steel pipe inside is made of plain concrete, so it is weak to external stress, difficult to interpret structurally, and reinforcement method is required.
그리고 또다른 방법으로서 안출된 것이 있는데, 이는 첨부도면 도3 에 도시된 바와같이 1m~2m의 대구경 강관을 터널시공예정면을 따라 지중에 압입한 다음, 상기 강관(10)과 강관(10)사이에 소구경 파이프(130)를 강관(10)과 나란히 수평으로 설치하고, 상기 소구경 파이프(130)와 양 강관(10)에 걸친 상부를 통상의 시멘트, 규산, 폴리우레탄과 같은 것으로 감싸거나 동결공법으로 감싸서 토사 붕괴 방지용 그라우팅부(70)를 형성한다음, 상기 강관들 측면에 지보공의 단면 직경크기 만큼 절개부를 형성하고 이에 지보공을 삽입한다음 지보공(110)과 강관들사이의 절개부의 간극을 용접후 각 지보공들의 연결부(115)를 연결하고, 상기 강관 내부에 콘크리트를 타설하는 방법을 반복하되, 그 구조물 내부위 토사를 굴착하고 상기 강관들의 하부측면을 철판(120)으로 상호연결 용접한 후 통상의 거푸집에 의한 콘크리트타설공법으로 지하구조물을 사전축조하는 방법이다.And another method has been devised, which is pressurized 1m ~ 2m large diameter steel pipe in the ground along the tunnel construction plan as shown in Figure 3, and then between the steel pipe 10 and the steel pipe (10) Install a small diameter pipe 130 in parallel with the steel pipe 10, and wrap or freeze the upper portion of the small diameter pipe 130 and the both steel pipes 10 with normal cement, silicic acid, and polyurethane. After forming a grouting part 70 to prevent the earth and sand collapse by wrapping the method, and forming a cutout in the side of the steel pipe as much as the cross-sectional diameter of the support hole and inserting the support hole therein, the gap between the support hole 110 and the incision between the steel pipes is formed. After welding, connecting the connection portion 115 of each support hole, and repeating the method of placing concrete in the steel pipe, excavating the soil inside the structure and the lower side of the steel pipe to the upper plate 120 Connected after welding is a method of pre-built an underground structure with cast-in-place concrete construction method according to a conventional die.
그러나, 이와같은 방법 또한 첫째로는 강관과 강관사이마다 길이가 긴 소구경파이프를 전부 원형식으로 설치하여야 하므로, 강관을 원형식으로 제작하기도 어렵고 제작비도 과다하며, 길이가 길어 설치가 곤란하고, 자재비 및 시공비가 많이 들며, 강관내에 추가로 충진공법이 없을 시 부식되어 취약하게 되며, 강관과 강관사이 고정연결핀이 없어 토압에 의해 강관이 이동될 수 있으며 구조물이 움직여 결정적인 문제가 야기 된다.However, in such a method, first of all, a long diameter pipe between the steel pipes and the steel pipes must be installed in a circular form. Therefore, it is difficult to manufacture the steel pipes in a circular form, the manufacturing cost is excessive, and the length is difficult to install. It costs a lot of materials and construction costs, and when there is no additional filling method in the steel pipe, it becomes vulnerable to corrosion, and there is no fixed connecting pin between the steel pipe and the steel pipe, so the steel pipe can be moved by earth pressure, and the structure moves, which causes a critical problem.
둘째로는 상기 강관 측면에 원형링의 단면 직경크기 만큼 절개부를 형성하고 이에 지보공(110)을 삽입하여야 하는데 강관길이가 길어 설치가 불가하며 단관으로 할땐 용접부위가 많아 시공이 어렵고 구조적으로 문제가 야기된다.Secondly, the incision is formed on the side of the steel pipe as much as the cross-sectional diameter size of the circular ring, and the support hole 110 is inserted therein, but the length of the steel pipe is long, so that it is impossible to install. do.
또한, 지보공(110)과 강관사이의 절개부의 간극을 용접후 각 지보공들의 연결부(115)를 연결설치하여야 하는 작업이 매우 복잡하고, 별도의 연결공정과 소구경 강관속채움이 필요하고 자재비가 과다하며 시공이 난이하다.In addition, after welding the gap of the cutout between the support hole 110 and the steel pipe, the work to connect and install the connection portion 115 of each support hole is very complicated, requires a separate connection process and small diameter steel pipe filling and excessive material costs The construction is difficult.
셋째로는 상기 대구경 강관(10) 내부 전체에 콘크리트를 타설하여야 하므로이 또한 자재비가 과다하게 들 뿐 아니라 소구경 파이프내에 콘크리트 타설이 어려워 부식으로 인한 구조해석이 안되며 강관과 강관 사이를 긴 파이프를 횡으로 설치하기가 어렵다.Third, since concrete should be poured in the entire inside of the large-diameter steel pipe 10, the material cost is not only excessive, but also concrete is difficult to be placed in the small-diameter pipe, and structural analysis due to corrosion is not possible. Difficult to install
넷째로는 상기 강관(10)들의 하부측면을 철판(120)으로 상호연결 용접하는 작업이 굴착후 천정에 용접해야 하는데 직진도(오차범위100mm)가 결여되어 용접이 불가하여 불편할 뿐만 아니라 별도의 철판(120)이 필요하므로 자재비가 과다하게 들어간다.Fourth, the work of interconnecting and welding the lower side of the steel pipes 10 to the steel plate 120 should be welded to the ceiling after excavation. Since 120 is required, the material cost is excessive.
