Description

암반터널의 라이닝 설치방법How to install lining of rock tunnel

본 발명은 암반터널의 내벽으로 사용되는 라이닝(lining)의 설치방법에 관한 것으로서, 특히 공장에서 제작된 프리캐스트 콘크리트(precast concrete)를 이용하여 암반터널에 라이닝을 설치함에 따라 공기를 단축시킬 수 있으며, 또한 공사비를 절감할 수 있고, 아울러 유지보수가 간편한 암반터널의 라이닝 설치방법에 관한 것이다.The present invention relates to a lining (lining) installation method used as the inner wall of the rock tunnel, in particular by using the precast concrete (precast concrete) produced in the factory can be shortened by installing the lining in the rock tunnel In addition, the present invention relates to a lining installation method of a rock tunnel, which can reduce construction costs and is easy to maintain.

일반적으로, 터널은 굴착→보강→콘크리트 라이닝의 설치와 같은 공정을 통해 건설되는데, 상기와 같은 콘크리트 라이닝은 통상적으로 현장타설 라이닝공법에 따라 설치된다.In general, the tunnel is constructed through a process such as excavation → reinforcement → concrete lining, and the concrete lining as described above is usually installed in accordance with the cast-in-place lining method.

도 4는 종래의 현장타설 라이닝공법에 따라 설치된 콘크리트 라이닝의 설치상태를 나타낸 터널 본선구간의 단면도로, 현장타설 라이닝공법은 굴착된 터널의 암반굴착면에 보강용 쇼크리트(shotcrete)(1)를 타설하고, 이 쇼크리트(1)의 외측면에 부직포와 방수시트(2)를 부착한 후, 라이닝폼을 거치하여 내측에 콘크리트를 주입·양생시켜 30∼40㎝ 두께의 라이닝(3)을 형성하는 공법이다. 따라서, 터널에서 발생되는 용출수는 부직포와 방수시트(2) 사이를 통해 배수된다.Figure 4 is a cross-sectional view of the tunnel main line showing the installation state of the concrete lining installed according to the conventional cast-in-place lining method, the cast-in-place lining method is a shotcrete (1) for reinforcement on the rock excavation surface of the excavated tunnel After pouring, attaching the non-woven fabric and the waterproof sheet 2 to the outer surface of the shockcrete 1, and then lining the foam, the concrete is injected and cured to form a lining 3 having a thickness of 30 to 40 cm. It is a technique. Thus, the effluent water generated in the tunnel is drained between the nonwoven fabric and the waterproof sheet 2.

그러나, 상기와 같은 종래의 현장타설 라이닝공법은 믹서트럭을 이용하여 공사현장으로 콘크리트를 운반하여 타설함에 따라 콘크리트의 품질을 균일하게 유지할 수 없으며, 콘크리트의 1일 타설공정이 7.2m/일 밖에 되지 않아 콘크리트 라이닝의 타설공기로 인하여 전체 도로공사가 지연될 수 있다는 문제점이 있었다.However, according to the conventional cast-in-place lining method as described above, the quality of concrete cannot be maintained uniformly by transporting concrete to the construction site by using a mixer truck, and the concrete's daily pouring process is only 7.2m / day. There was a problem that the entire road construction can be delayed due to the pouring air of the concrete lining.

또한, 터널에서 발생되는 용출수를 배수시키는 부직포가 이물질로 막히는 경우에는 부직포의 배수효율이 저하되고, 이로인해 라이닝으로 침투한 용출수의 수압에 의해 라이닝에 균열이 발생함에 따라 터널이 붕괴될 수 있다는 문제점이 있었다.In addition, when the nonwoven fabric draining the effluent generated in the tunnel is clogged with foreign matter, the drainage efficiency of the nonwoven fabric is reduced, and as a result, the tunnel may collapse due to cracking in the lining due to the pressure of the effluent penetrated into the lining. There was a problem.

아울러, 콘크리트 라이닝이 터널의 전구간에 걸쳐 일체로 형성됨에 따라 건설된 터널의 하자 발생시 이를 보수하기 어렵다는 문제점이 있었다.In addition, since the concrete lining is integrally formed over the entire span of the tunnel, there is a problem that it is difficult to repair it when a fault occurs in the constructed tunnel.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 공장에서 제작된 프리캐스트 콘크리트(precast concrete)인 측벽패널과 아크패널을 이용하여 라이닝을 설치함에 따라 공기를 단축시킬 수 있으며, 또한 공사비를 절감할 수 있고, 아울러 유지보수가 간편한 암반터널의 라이닝 설치방법을 제공하는 것을 그 목적으로 한다.Accordingly, the present invention has been invented to solve the above problems, it is possible to shorten the air by installing the lining by using the precast concrete sidewall panel and arc panel manufactured in the factory, and also the construction cost The purpose is to provide a method of installing the lining of the rock tunnel can be reduced, and easy to maintain.

상기와 같은 목적을 달성하기 위하여 본 발명은, 프리캐스트 콘크리트(precast concrete)인 측면패널과 아크패널을 고정하기 위한 다수의 앵커볼트를 터널의 암반굴착면에 삽입·고정하고 터널의 기저부에는 측벽패널을 고정하기 위한 풋팅세그먼트(footing segment)를 설치하는 제 1 공정과, 상기 제 1 공정에서 설치된 풋팅세그먼트에 측면패널을 거치하고 측면패널의 결합홀에 앵커볼트를 삽입·체결하여 측면패널을 암반굴착면에 고정시키는 제 2 공정과, 상기 제 2 공정에서 고정된 측벽패널의 단부에 아크패널의 단부를 일치시키고 아크패널의 결합홀에 앵커볼트를 삽입·체결하여 아크패널을 암반굴착면에 고정시키는 제 3 공정과, 상기 제 2 및 제 3 공정을 통해 고정된 패널과 암반굴착면 사이의 공간에 충전물을 채우는 제 4 공정을 구비하는 것을 특징으로 한다.In order to achieve the above object, the present invention, a plurality of anchor bolts for fixing the side panel and the arc panel of the precast concrete (inserted and fixed to the rock excavation surface of the tunnel and the side wall panel at the base of the tunnel) The first step of installing a footing segment for fixing the pressure, and mounting the side panel to the footing segment installed in the first step and inserting and fastening the anchor bolt into the coupling hole of the side panel rock excavation of the side panel The second step of fixing to the surface, and the end of the side wall panel fixed in the second process to match the end of the arc panel and inserting and fastening the anchor bolt into the coupling hole of the arc panel to fix the arc panel to the rock excavation surface And a fourth step of filling a filler in the space between the panel fixed through the second and third steps and the rock drilling surface. do.
