최근 도로 및 철도와 같은 SOC사업 계획의 기본방향은 중요한 사회간접자본인 토지의 효율적인 활용을 우선시하는 추세에 따라 교량이나 터널과 같은 구조물이 증가하고 있으며, 이로 인해 교량이나 터널 공사의 중요성 및 국민의 관심이 집중되고 있으나 터널 공사의 증가에 따른 하자 발생률 또한 증가하게 되는 문제점이 야기되고 있는 실정이다.Recently, structures such as bridges and tunnels are increasing according to the trend of prioritizing the efficient use of land, which is an important social overhead capital, as the basic direction of SOC project plans such as roads and railways. Although interest is being focused, the problem that the defect occurrence rate also increases due to the increase in tunnel construction is being caused.

이러한 터널 공사에서 시공자와 감리자가 민감하게 체감하고 있는 하자 중에는 방수공사에 따른 하자를 들 수 있으며, 각종 자료에 의하면 다양하고 많은 터널 내 방수공사의 부실시공에 대해 보고되고 있는 실정이다.Among the defects that constructors and supervisors are sensitive to in tunnel construction, defects due to waterproofing work can be cited.

도 1a에 의하면 이러한 터널공사에 적용되는 방수공사의 일예를 살펴볼 수 있는데 지반의 굴착면(100)에 숏크리트(101)를 타설하고, 숏크리트(101)면에 부직포(5)에 일정한 간격으로 열융착하여 방수시트(102-1)를 접합한 방수부재(102)를 숏크리트(101)가 타설된 굴착면에 날개부재 또는 란델을 이용하여 부직포(102-2)를 부착시킨 후, 라이닝콘크리트(103)를 방수시트(102-1)를 경계면으로 하여 일정한 두께로 타설하게 된다.According to Figure 1a, an example of waterproofing work applied to such a tunnel construction can be seen. Shotcrete 101 is poured on the excavated surface 100 of the ground, and the shotcrete 101 surface is thermally fused to the nonwoven fabric 5 at regular intervals After attaching the waterproof member 102 to which the waterproof sheet 102-1 is bonded to the excavation surface on which the shotcrete 101 is placed, the non-woven fabric 102-2 is attached using a wing member or randel, and then the lining concrete 103 is poured at a constant thickness with the waterproof sheet 102-1 as a boundary surface.

이에 지반을 굴착하면서 굴착면으로 유입되는 지하수 등이 부직포(102-2)를 따라 터널 하부에 별도로 설치된 배수관으로 유도 배수되도록 하고 부직포(102-2)를 따라 유도되는 지하수 등이 터널 내부로 누수 되지 않도록 방수시트(102-1)로 부직포(102-2)를 마감하고 있음을 알 수 있다.Accordingly, while excavating the ground, the groundwater, etc. flowing into the excavation surface is induced and drained along the nonwoven fabric 102-2 to a drainage pipe installed separately at the bottom of the tunnel, and the groundwater guided along the nonwoven fabric 102-2 does not leak into the tunnel. It can be seen that the nonwoven fabric 102-2 is finished with the waterproof sheet 102-1 so as not to

Accordingly, the waterproof member 1 of the present invention is a nonwoven fabric 2 ) and the waterproof sheet 3 are joined by thermal fusion at regular intervals, in the waterproof member 1, an induction drain 4 is provided on one side of the waterproof sheet 3, and the induction drain 4 has water It is a structure in which a water-soluble filler (5) dissolved in reaction with is filled and installed to fill the induction drain (4).

상기 부직포(21)는 단섬유가 적층되어 이루어진 구조 또는 장섬유를 적층한 구조의 것 중 어느 하나이며 재질로는 PE, PP 중 어느 하나로 이루어진 구조이며, 상기 방수시트(3)는 HDPE, EVA, PET, EPDM 중어느 하나를 사용하며 유도배수로는 사각형, 반원형, 중 어느 하나의 형상으로 이루어진 구조이다.The non-woven fabric 21 is either a structure in which short fibers are laminated or a structure in which long fibers are laminated, and the material is a structure made of any one of PE and PP, and the waterproof sheet 3 is HDPE, EVA, Any one of PET and EPDM is used, and the induction drain has a structure consisting of either a square or semicircular shape.

상기 수용성 채움재로(5)는 수용성 잉크, 수용섬 염료, 수용성 합성수지를 사용하며 상기 수용성 잉크로는 아크릴 타입, 우레탄 타입 중 어느 1종을 사용하며, 수용섬 염료는 벤젠아조나프톨, 벤젠아조-1-페닐-5-피라졸론, 벤젠아조벤젠, 나프탈렌-아조벤젠, 벤젠아조아미노나프탈렌, 나프탈렌아조나프탈렌, 나프탈렌아조-1-페닐 -5-피라졸론, 벤젠아조피리돈 및 나프탈렌아조피리돈 등 중 어느 1종 이상인 것을 사용한다.As the water-soluble filler 5, water-soluble ink, water-soluble dye, and water-soluble synthetic resin are used. As the water-soluble ink, either an acrylic type or a urethane type is used, and the water-soluble dye is benzene azonaphthol, benzene azo-1 - Any one of phenyl-5-pyrazolone, benzene-azobenzene, naphthalene-azobenzene, benzene-azoaminonaphthalene, naphthalene-azonaphthalene, naphthalene-azo-1-phenyl-5-pyrazolone, benzene-azopyridone, and naphthalene-azopyridone. use more than

상기 수용성 합성수지로는 폴리비닐 부틸알콜, 폴리아크릴 아미드, 메틸롤화 요소수지, 메틸롤화 멜라민수지, 및 카르복시메틸셀룰로오스로 이루어지는 군으로부터 하나 이상 선택하여 사용할 수 있다. As the water-soluble synthetic resin, at least one selected from the group consisting of polyvinyl butyl alcohol, polyacrylamide, methylolate urea resin, methylolate melamine resin, and carboxymethylcellulose may be used.

한편 상기 수용성 채움재(5)는 유도배수로(4)에 인입되어 설치됨에 있어서 첨부도면 도 3 및 도 4a에 도시된 바와 같이 2/3만 채워지는 것이 바람직하다. 그 이유는 라이닝콘크리트를 타설하게 되면 수용성 채움재(5)가 메워지지 않은 나마지1/3의 유도배수로(4)로 라이닝콘크리트가 채워지게 되면서 그대로 양생되면 방수시트(2)와 라이닝콘크이트의 결합력을 증대시키게 된다.On the other hand, as the water-soluble filler 5 is inserted into the induction drain 4 and installed, it is preferable that only 2/3 of it be filled as shown in FIGS. 3 and 4A of the accompanying drawings. The reason for this is that when the lining concrete is poured, the water-soluble filler (5) is not filled, but the lining concrete is filled with 1/3 of the drainage channel (4), and when cured as it is, the waterproof sheet (2) and the lining concrete increase bonding strength.

한편 라이닝콘크리트가 첨부도면 도 4b에 도시된 바와 같이 수용성 채움재(5)가 메워지지 않은 유도배수로(4)에 채워지면 라이닝콘크리트 타설시 포함되어 있던 물을 유도배수로(4) 쪽으로 안내하는 역활을 수행하게 되며 유도배수로 쪽으로 안내된 물은 수용성 채움재(5)와 반응하여 유도배수로(4)를 이용하여 나머지 2/3을 개방하여 물(수분)을 배수하게 되므로 라이닝콘크리트의 양생이 보다 빨리 이루어지는 효과를 얻을 수 있게 되는 것이다. 또한 방수부재(1)와 라이닝콘크리트 사이로 유입된 물도 용이하게 배출할 수 있는 효과를 갖게 된다.On the other hand, as shown in FIG. 4B of the accompanying drawing, when the water-soluble filler (5) is filled in the induction drainage channel (4) where the lining concrete is not filled, it serves to guide the water contained in the pouring of the lining concrete toward the induction drainage channel (4). And the water guided toward the induction drain reacts with the water-soluble filler (5) to open the remaining 2/3 using the induction drainage (4) to drain water (moisture), so the effect of curing the lining concrete more quickly will be able to get In addition, it has an effect of easily discharging water introduced between the waterproof member 1 and the lining concrete.
