본 발명은 토사층에 지하터널을 구축함에 있어서 종래에 사용되었던 토류판(土留板)을 사용치 않고 콘크리이트세그먼트를 사용하므로서 굴착면으로 부터 전달되는 여러 하중조건을 효과적으로 안정되게 처리함과 동시에 간편하고 경제적으로 지하터널을 구축할 수 있도록 된 지하터널 구축공법에 관한 것이다.In the present invention, when constructing underground tunnels in soil layers, concrete segments are used without using soil plates, which are conventionally used. It is about underground tunnel construction method that can build underground tunnel.

일반적으로 메서시일드(Messer Shield) 공법에 의해 터널을 구축하는 방법은, 메서(Meser, 鋼矢板)를 추진시켜 굴진 작업을 한뒤 일정간격으로 철강지보공(支保工)을 세우고, 이들 인접한 지보공사이에 토류판(土留板)을 끼운 다음 이 지보공과 토류판을 함께 라이닝콘크리이트로써 매설하도록 되어 있어, 종래의 터널구축공법보다 그 안정성 및 시공성 면에서 개량된 것이기는 하나 그 공법이 번거롭고 공사기간이 길며 경제적으로도 손실이 크다는 결점이 있었다.In general, the method of constructing a tunnel by the Messer Shield method is to protrude a messer and excavate, and then establish steel support at regular intervals. Since the earth plate and the earth plate are embedded as lining concrete after the earth plate is inserted, it is improved in terms of stability and workability compared to the conventional tunnel construction method, but the method is cumbersome, the construction period is long and economical. There was also a drawback of large losses.

즉, 종래의 메서시일드공법은 터널막장을 굴착할때 터널의 형상에 따라 지보공위에 메서를 병렬로 배열하고, 유압잭(JACK)으로 각 메서를 압입전진시키면서 막장을 굴착한 다음, 그 후방에 상기 메서가 진행됨에 따라 일정간격으로 설치한 지보공과 지보공사이에 토류판을 끼워 굴착면에 따라 받쳐가는 공법으로서, 이공법은 막장 굴착과 토류판설치 및 지보공설치등의 작업이 메서라른 복공철갑내에서 연속적으로 안전하게이루어진다는 점에서 시일드공법과 산악터널공법의 조합공법이라 할 수 있는바, 이러한 메서시일드공법은 대형굴착공사나 하수로관등을 매설하는 공사등 각종 굴착공사를 무소음, 무진동으로 시공할 수 있고, 높은 안전성과, 정확한 굴진, 신속한 작업진행, 굴착면과의 공간을 없애줌으로써 굴착면 침하의 극소화, 다양한 굴착공사에 응용가능, 작업장비의 단순화, 공사방법 용이 및 경제적인 시공 가능 등 그 효과가 매우 좋은것으로 평가되기는 하였다.In other words, in the conventional method of shielding the tunnel, the mesuring shields are arranged in parallel on the support hole according to the shape of the tunnel, and the membranes are excavated by pushing and advancing each mesger with a hydraulic jack, and then the rear of the tunnel. As the method progresses, the earthwork and the earthwork are installed at regular intervals, and the earth plate is supported by the excavation surface.This method is a continuous process in the perforated iron box where the work such as membrane digging, earth plate installation, and earthwork installation is difficult. It can be called as a combination method of shield method and mountain tunnel method in that it can be safely performed.The method method can be used to construct various excavation works such as large excavation works or laying sewer pipes with no noise and without vibration. High safety, accurate excavation, rapid work progress, minimization of excavation surface settlement by eliminating space with excavation surface, various excavation hole It has been evaluated that the effect is very good such as application to the company, simplification of work equipment, ease of construction method and economical construction.

그러나, 상기와 같은 종래의 메서시일드공법은, 메서를 막장에 압입추진하여 막장을 굴착한 다음, 지보공을 설치하고, 지보공과 지보공사이에 토류판을 끼워 넣어 굴착면을 보호한 상태로 1차 콘크리이트라이닝 및 2차 콘크리이트라이닝등의 시공순서를 거쳐야 하므로, 첫째, 지보공과 트류판등 막대한 지보재(支保材)가 라이닝콘크리이트속으로 매몰됨으로 인해 지보재의 낭비가 심하게 되고, 둘째, 다량의 지보재를 운반하거나 설치하는데 따른 공사비의 부담이 크며, 셋째, 시공과정이 복잡하여 공사가 어렵고 또 공사기간이 오래 걸리는 등의 문제점이 있었다.However, according to the conventional method of the method, the method is to press the propulsion method to the membrane to excavate the membrane, install the jibo ball, and then install the earth plate in the jibo ball and the jibo construction to protect the excavation surface. Since it is necessary to go through the construction procedure such as triening and secondary concrete lining, firstly, huge support materials such as jibo balls and truncated plates are buried in the lining concrete, and secondly, a large amount of support materials are used. The burden of construction costs due to transportation or installation is large, and third, the construction process is complicated, and the construction is difficult and the construction period takes a long time.

이에 본 발명은 상기와 같은 종래의 메서시일드공법상의 제반 문제점을 해결하기 위해 발명된 것으로, 메서를 압입전진시켜 터널막장을 굴착해 나가면서 굴착된 공간에 차례로 지보공을 세우고, 이들 지보공과 지보공사이에 토류판 대신에 적절한 형상으로된 콘크리이트세그먼트를 끼워 넣어 연속조립시킨 다음, 이와같이 연속조립된 콘크리이트세그먼트로 형성되는 벽체에 한번의 콘크리이트라이닝 처리만으로 공사가 마무리될수 있도록 하는 한편, 상기 지보공은 계속적으로 반복사용할 수 있도록 하여 종래의 메서시일드공법의 장점은 그대로 유지하면서도 간편하고 신속하며 경제적으로 지하터널을 구축할 수 있는 지하터널 구축공법을 제공하는 데 그 목적이 있다.Accordingly, the present invention was invented to solve the problems of the conventional method of the method, such as, press-advance the messer to excavate the tunnel curtain in order to set up the jibo in the excavated space, and these jibo and jibo Instead of the earth plate, the appropriately shaped concrete segment is inserted and continuously assembled, and then the construction can be completed by only one concrete lining treatment on the wall formed by the continuously assembled concrete segment, while the support is continuously The purpose of the present invention is to provide an underground tunnel construction method for constructing an underground tunnel easily, quickly and economically while maintaining the advantages of the conventional method of shielding method.

Since the wall to be formed has an effect of forming the primary lining concrete itself, the entire process is completed by forming only one lining concrete on the wall.

이상의 설명에서와 같은 본 발명 지하터널구축공법을 제4도 및 제5도에 도시한 종래의 메서시일드공법과 비교하여 보면, 제4도에 도시된 바와같이 종래의 메서시일드공법은 메서(1)의 굴진에 따라 지보공(2)을 계속 세워 설치하고, 이들 지보공(2)들 사이에 나무로 된 토류판(14)을 꺼워 넣으면서 굴착작업을 진행한 다음 제5도에서와 같이 토류판(14)으로 형성되는 벽체에 1, 2차 라이닝콘크리이트(15, 16)를 각각 형성시킴으로써 공정이 마무리 되게 되는바, 이와 같이하여 완성된 터널단면을 보면 지보공(2)과 토류판(14)이 1차 라이닝콘크리이트(15) 형성시 매몰되어 자체가 벽체의 일부를 구성하게 되므로 재사용할 수가 없고 그대로 소모되는 것이다.Compared to the conventional method of the tunnel construction method of the present invention as described above in the conventional method shown in FIGS. 4 and 5, as shown in FIG. According to the excavation of 1), the support ball 2 is continuously installed, the excavation work is carried out while the wooden earth plate 14 is put in between the support ball 2, and the earth plate 14 as shown in FIG. The process is completed by forming the primary and secondary lining concrete (15, 16), respectively, on the wall formed by the bar. When the concrete 15 is formed, it is buried so that it forms part of the wall, and thus cannot be reused and is consumed as it is.

따라서, 본 발명은 종래에 사용된 토류판(14)를 사용치 않고 적절한 형태를 갖춘 콘크리이트세그먼트(5)를 사용하는 것으로, 종래에는 지보공(2)과 토류판(14)이 1차 라이닝콘크리이트(15)에 의해 매몰되었지만 본발명에서는 콘크리이트세그먼트(5)가 연속해서 견고하게 조립되어 형성되는 벽체가 종래의 1차 라이닝콘크리이트(15)의 역할을 하게 됨으로써 이에 단 한번의 라이닝콘크리이트(8)를 형성시킴으로써 공정을 마무리할 수 있도록 되어 공정이 간편할 뿐만 아니라 작업단가를 감소시킬 수가 있다.Therefore, the present invention uses a concrete segment 5 having an appropriate shape without using the earth plate 14 used in the related art. In the related art, the support hole 2 and the earth plate 14 are formed of primary lining concrete ( Although it was buried by 15), in the present invention, the concrete segment 5 is formed by successively assembling a wall, which serves as a conventional primary lining concrete 15, thereby allowing only one lining concrete 8 ) Can be used to finish the process, which not only simplifies the process but also reduces the operating cost.

한편 본 발명에 따른 상기 콘크리이트세그먼트(5)는 직4각형상 뿐만 아니라 다른 여러형태로 된 것을 사용할 수도 있는바, 특히 굴착하고자 하는 장소의 토질이나 주변조건등에 따라 그 크기와 형상을 적절히 변형시킬 수 있고, 또 이에 사용되는 지보공(2a,2b,…,2f)도 적당한 형상 및 칫수를 갖는 것으로 할 수 있음과 더불어 이들 사이의 간격을 조절해서 사용할 수 있다.Meanwhile, the concrete segment 5 according to the present invention may use not only rectangular shapes but also other forms of various shapes. In particular, the size and shape of the concrete segment 5 may be appropriately modified according to the soil quality and the surrounding conditions of the place to be excavated. In addition, the support holes 2a, 2b, ..., 2f used for this can be made to have a suitable shape and dimension, and can also be used by adjusting the space between them.

이상의 설명에서와 같이 본 발명은, 메서(1)가 굴진작업을 해나감에 따라 지보공(2a,2b,…,2f)을 차례로 설치하고, 이들 지보공(2a,2b,…,2f) 사이에 결합홈(3)과 결합돌기(4)를 갖춘 콘크러이트세그먼트(5)를 연속해서 견고하게 조립해준 다음, 상기 지보공(2a,2b,…,2f)을 차례로 해체하여 앞쪽에다 새로운 지보공(2a',2b',…,2f')으로 재사용할 수 있도록 하므로서, 터널을 시공할 경우 지보재등의 낭비가 없어 지보재비용이 대폭 절감되고, 지보재등의 운반과 설치등의 번잡성으로 인한 공사비의 부담을 격감시킬 수 있을 뿐만 아니라 시공과정이 간단하게 되며, 또 연속해서 조립된 콘크리이트세그먼트(5) 자체가 벽체를 형성함으로써만 한번의 라이닝콘크리이트(8)만을 형성시킴으로써 공사를 마무리 할 수 있도록 되어 공사기간을 대폭 단축시킬 수 있는 등의 효과가 있는 것이다.As described above, according to the present invention, the supporters 2a, 2b, ..., 2f are sequentially provided as the mesmer 1 performs the excavation work, and the coupling between these support holes 2a, 2b, ..., 2f is performed. The concrete segments (5) with the groove (3) and the engaging projection (4) are successively assembled, and then the support holes (2a, 2b, ..., 2f) are dismantled in turn to form a new support hole (2a ') in front. , 2b ',…, 2f'), so that when constructing a tunnel, there is no waste of paper and other materials, which greatly reduces the cost of paper and the burden of construction costs due to the complexity of transportation and installation of paper and other materials. Not only can it be greatly reduced, but also the construction process is simple, and the concrete segments (5) assembled in succession form a wall only to form a lining concrete (8) to finish the construction.
