일반적으로, 터널은 교통, 통수 등의 목적으로 산악, 지하 또는 수저 등에 홀을 형성한 갱도를 말하는 것으로, 주로, 도로 또는 철도 등의 건설시 경로를 확보하기 위해 건설된다. In general, a tunnel refers to a tunnel in which a hole is formed in a mountain, an underground, a cutlery, or the like for the purpose of transportation, water passage, etc., and is mainly constructed to secure a path during construction of a road or a railway.

이러한, 터널을 시공하는 방법으로 땅을 굴착하여 콘크리트로 구체를 형성하는 방법이 주로 사용되고 있다. 땅을 굴착하는 방법은 기계를 사용하여 굴착하거나 발파를 이용한 방법이 사용된다. 터널 공법으로는 지반이 가진 특성을 최대한 이용 하는 NATM(New Austrian Tunneling Method)공법이 개발되어 있다.As a method of constructing a tunnel, a method of excavating the ground and forming a sphere from concrete is mainly used. The excavation method is a method of excavation using a machine or a blasting method. As a tunnel method, a NATM (New Austrian Tunneling Method) method has been developed that utilizes the characteristics of the ground.

도 1 은, 종래의 터널 누수방지 구조를 도시한 단면도이다.1 is a cross-sectional view showing a conventional tunnel leak prevention structure.

도시된 바와 같이, 터널의 시공 예정 부위에 굴착 또는 발파 작업을 통하여 기초터널을 형성하고, 쇼크리트(Shotcrete, 20)를 분사하여 시공한 후, 방수층(30)을 시공한 다음, 터널 내벽을 보호하는 라이닝 콘크리트(Lining Concret, 40)를 타설하는 방식으로 이루어진다. 이 과정에서, 방수층(30)은 쇼크리트(20) 시공면의 상부에 부직포를 고정 설치하고, 이 부직포의 상부에 방수시트를 적층함으로써 형성된다. 그리고, 쇼크리트(20)를 통과하여 내부로 유입된 물이 부직포를 따라 하부로 흘러내려 배수될 수 있도록 터널과 나란하게 설치된 종배수관(50) 및 터널의 내측방향으로 소정의 경사각을 가지고 구비된 횡배수관(60)을 통해 유입되어 배수수단(70)을 통해 배수되도록 이루어져 있다. As shown, after forming the foundation tunnel through the excavation or blasting work to the construction site of the tunnel, by spraying the shotcrete (20), after constructing the waterproof layer 30, and then protects the tunnel inner wall Lining concrete (40) is made by pouring. In this process, the waterproof layer 30 is formed by fixing the nonwoven fabric on top of the construction surface of the shockcrete 20 and laminating the waterproof sheet on the top of the nonwoven fabric. In addition, the water drainage pipe 50 is installed in parallel with the tunnel and has a predetermined inclination angle in the inner direction of the tunnel so that the water introduced into the interior through the shockcrete 20 flows down the drain along the nonwoven fabric. Is introduced through the horizontal drain pipe 60 is made to drain through the drain means (70).

그러나, 종래의 터널의 방수구조에 의하면, 예를 들어, 외기의 온도가 -15℃ 이하일 경우, 터널(10) 내로 차가운 외기가 유입되면서 종배수관(50)과 횡배수관(60)의 내부온도가 영하로 떨어져 종배수관(50)과 횡배수관(60)의 결빙으로 배수 기능이 저하되어 지하수가 방수층(30)과 라이닝 콘크리트(20) 사이로 역류되고, 시공 이음부를 따라 상승되면서 고드름 등이 형성되고, 기온 상승시 융해되어 낙수현상이 발생하는 문제점이 있었다. 또한, 일평균 기온이 0℃ 이하의 온도가 300℃·day 이상인 동결지수를 갖는 한랭지인 경우 지반의 동결에 의한 라이닝 콘크리트(20)의 동상 가능성이 존재한다.However, according to the conventional waterproof structure of the tunnel, for example, when the temperature of the outside air is -15 ℃ or less, the internal temperature of the vertical drain pipe 50 and the horizontal drain pipe 60 is increased while the cold outside air flows into the tunnel 10 Falling below zero, the drainage function is reduced by the freezing of the vertical drainage pipe 50 and the horizontal drainage pipe 60, the groundwater flows back between the waterproofing layer 30 and the lining concrete 20, as the icicles are formed while rising along the construction joint, There was a problem in that the fall caused by melting when the temperature rises. In addition, when the daily average temperature is a cold district having a freezing index of 300 ° C day or more at a temperature of 0 ° C or less, there is a possibility of frostbite of the lining concrete 20 by the freezing of the ground.

이러한, 문제점을 해결하기 위해 열유동 해석을 통한 소요 열량과 설치 위치 등을 산정함으로써 열풍기 및 시공이음부에 열선 등을 설치하여 기온이 급격히 저하될 때 가동되도록 하는 방안이 개시되어 있으나, 이러한 경우, 열풍기 및 열선 등의 별도의 동결방지수단을 구비 및 동결방지수단의 고장시 이를 수리 또는 교환해야 하는 데에도 막대한 예산 및 시간이 소요되는 문제점이 있었다. In order to solve such a problem, a method of installing a heating wire on a hot air fan and a construction joint by calculating a required heat amount and an installation position through thermal flow analysis is disclosed so as to operate when the temperature drops sharply. There is a problem in that a huge budget and time are required to provide a separate freeze protection means such as a hot air fan and a heating wire and to repair or replace the freeze protection means.

또한, 한랭지 또는 추운 날씨에서 터널에 발생되는 물을 배수하는 배수관이 동결되어 배수효율이 저하되고, 이로 인해, 동결되지 않은 지하수의 수위가 상승함에 따라 라이닝 콘크리트에 수압이 설계한 값보다 크게 되어 라이닝 콘크리트에 균열 발생 및 터널이 붕괴되는 현상 또는 터널라이닝 배면의 지하수 동결에 의한 동상 발생으로 동상에 의한 팽창압이 라이닝 콘크리트에 작용하여 균열, 열화 등으로 터널이 붕괴되는 현상 등의 심각한 재해를 발생시킬 수도 있다. In addition, the drainage pipe that drains the water generated in the tunnel in the cold or cold weather is frozen, and the drainage efficiency is lowered. As a result, the water pressure in the lining concrete becomes greater than the designed value as the level of the unfrozen groundwater rises. Due to cracks in concrete and tunnel collapse or frostbite caused by freezing of groundwater on the back of tunnel lining, expansion pressure due to frostbite acts on lining concrete, which can cause severe disasters such as tunnel collapse due to cracking and deterioration. It may be.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 단열재 등의 단열수단을 구비하여 고가의 열풍기 및 열선 등의 동결방지수단을 구비하지 않고도 한랭지 또는 추운 날씨에서도 배수관의 동결 및 터널 배면의 지하수 동결을 방지하여 배수효율을 극대화할 수 있을 뿐만 아니라 소요비용을 최대한 절감할 수 있도록 하는 데 그 목적이 있다. The present invention has been made to solve the above problems, provided with a heat insulating means such as a heat insulating material without freezing prevention means such as expensive hot air fans and hot wires, even in cold or cold weather, freezing of the drain pipe and groundwater on the back of the tunnel The purpose is to prevent freezing to maximize drainage efficiency and to reduce the required cost as much as possible.

도 2 내지 도 4에 도시된 바와 같이, 본 발명은, 터널(100)의 쇼크리트(110) 타설 면에 부직포(122)와 방수시트(124)가 고정 설치되어 방수층(120)이 형성되고, 방수층(120)에 라이닝 콘크리트(130)가 타설되어 이루어지는 터널 라이닝에서 방수시트(124) 및 라이닝 콘크리트(130)의 사이에 적층되는 단열수단(140)을 포함하는 것을 특징으로 한다.

이와 같이, 형성된 기초터널의 굴착면은 굴곡이 심하여 후속 방수 작업을 하기에 부적합하므로, 기초터널의 굴착면을 안정시킴과 아울러 방수 바탕면을 평탄하게 만들기 위해 쇼크리트(110)를 분사하여 시공한다. 이 쇼크리트(110)는 암반굴착면에 삽입·고정되는 록 볼트(112) 등에 의해 암반(150)에 고정된다.Thus, since the excavation surface of the formed foundation tunnel is severely unsuitable for subsequent waterproofing work, the shockcrete 110 is sprayed to stabilize the excavation surface of the foundation tunnel and to flatten the waterproof base surface. . The shockcrete 110 is fixed to the rock 150 by a lock bolt 112 or the like inserted into and fixed to the rock excavation surface.

그리고, 기초터널 내부로 유입되는 지하수의 침투를 방지하기 위해 방수층(120)을 시공한 다음, 터널 내벽을 보호하는 콘크리트 보각 벽체인 라이닝 콘크리트(130)를 타설하는 방식으로 이루어진다. Then, the waterproof layer 120 is constructed to prevent the penetration of groundwater flowing into the basic tunnel, and then the lining concrete 130 that is a concrete complementary wall to protect the inner wall of the tunnel is formed.

The water penetration prevention material 146 allows a plurality of bending guide marks 146a to be selectively formed horizontally and vertically on one or both surfaces thereof, so that the bending can be smoothly performed anywhere in the stacked portion. It can be easily laminated between the waterproof sheet 124 and the lining concrete 130 is constructed in an arc shape can improve the work efficiency.
