본 발명은 콘크리트 구조물의 누수부위를 근본적으로 방수처리시킬 수 있도록 한 콘크리트 구조물의 누수부위 방수처리방법에 관한 것이다.The present invention relates to a method of waterproofing a leaky site of the concrete structure to be able to fundamentally waterproof the leaky site of the concrete structure.

종래에는 예를들어 건축물등의 콘크리트 구조물의 어느 한 부위에 균열 또는 시공상의 잘못으로 인한 누수가 발생될 경우 임시 방편으로 해당부위를 차단하는 식의 간단한 조치에 의해 해결되어 왔지만 이는 근본적인 해결책이 되지 못할뿐만 아니라 오히려 전체적인 구조상의 손상을 가져올 수 있는 문제점들이 있고 이에 따른 안전사고의 위험한 요인이 되어 왔다.In the past, for example, if a leak occurs due to a crack or construction error in a part of a concrete structure such as a building, it has been solved by a simple measure of blocking the part as a temporary measure, but this is not a fundamental solution. Rather, there are problems that can cause the overall structural damage and have been a dangerous factor of safety accidents.

특히 지하철 공사와 같은 콘크리트 구조물에서는 이와같은 누수차단방법이 매우 중요한 것이므로 이하 종래의 방법 및 본 고안의 방법에 관한 설명을 지하철 공사에 적용한 콘크리트 구조물을 대표적인 예로써 상술하고자 한다.In particular, concrete leaks such as subway construction is such a leak-proof method is very important, and will be described below as a representative example of the concrete structure applied to the conventional method and the description of the method of the present invention to the subway construction.

예를들면, 종래의 지하철 공사에서의 내부시공은 제1도에 도시한 바와같이 지하에 철근구조물(1)을 수직으로 설치하고 기초 콘크리트(2)와 측면 콘크리트(3)를 깔고 그 위에 방수 쉬트지(4)와 몰탈(5)을 도포한후, 철근과 함께 콘크리트(6)를 설치한다. 콘크리트(6)상에는 승하차장인 헌지(7)를 좌우형성시키고 또한 2차 콘크리트 구조물(8)을 지붕식으로 설치하고, 양생이 되면 구조물(8)주변 양면의 거푸집을 철거시킨 후 상기 구조물(8)위에 방수 쉬트지(4)와 몰탈(5)을 도포하고 최외층에는 벽돌구조물(9)을 형성시킨다. 그리고 최종적으로 벽돌구조물(9)주위를 굴착토로 덮으므로써 지하철이 통행가능한 지하철 구조물이 완성되는 것이다.For example, the internal construction in the conventional subway construction, as shown in FIG. 1, is installed vertically the reinforcement structure (1) in the basement, laying the foundation concrete (2) and side concrete (3) and a waterproof sheet thereon After the paper 4 and mortar 5 are applied, concrete 6 is installed together with the reinforcing bars. On the concrete (6) form the left and right hunt (7), and also install the secondary concrete structure (8) in the roof type, and when curing is to remove the formwork on both sides around the structure (8) the structure (8) The waterproof sheet 4 and the mortar (5) is applied on the outermost layer to form a brick structure (9). Finally, by covering the surrounding brick structure (9) with excavated soil, the subway structure through which the subway can pass is completed.

그러나 콘크리트 구조물(8)이 시공상 콘크리트 타설시 사용재료의 배합잘못, 또는 거푸집을 떼어낸 콘크리트 구조물 외벽의 면이 거푸집에 의해 "+"자형의 돌출부가 형성되어 매끄럽지 못해 시공과정에서 방수 쉬트지(4)에 손상이가면 그 손상부로 물이 흘러들어가 콘크리트 구조물(8)에 형성된 균열부(10)를 통해 누수가 발생하게 된다.However, when the concrete structure 8 is inadequate in mixing the materials used for construction, or the surface of the outer wall of the concrete structure from which the formwork is removed, the protrusions of the "+" shape are formed by the formwork and are not smooth. If 4) is damaged, water flows into the damaged part and leaks through the crack part 10 formed in the concrete structure 8.

이 경우 종래에는 상기균열부(10)에 구조물의 내부 전면에서 방수제를 도포시키거나 누수가 되는 지점에서 그라우팅하여 방수처리를 하였으나, 이러한 종래의 방법으로는 거푸집의 이음부분에 생기는 "+"자형의 돌출부가 완전제거되지 못한 상태이므로 물이 "+"자형 돌출부(유로)에 고여있다가 지하수의 압력이 증가할 경우 방수처리가 미약했거나 벽체의 수밀콘크리트가 견고히 타설되지 않았을 경우에는 또다시 누수현상이 발생할 수도 있었다. 또한 길게 형성된 균열부(10)위에 별도의 유도배수관을 만들어 배수로로 물을 배출시키는 방법을 사용하여 왔었다. 그러나 이 방법 역시 임시처리 방법에 불과한 것이어서 3년 내지 4년정도 경과하면 백태현상이 발생하여 배수관이 막혀 벽체에 누수가 재발되고 결과적으로 균열의 크기도 점점 확대되어 구조물 전체의 안정성에 영향을 미치게 되는 문제점이 있었다.In this case, in the prior art, the cracking part 10 was coated with a waterproofing agent on the inner surface of the structure or grouted at a point where water was leaked. However, in the conventional method, a "+" shape formed at the joint part of the formwork is formed. Since the protrusions are not completely removed, the water is stuck to the "+" shaped protrusions (euro), but if the groundwater pressure increases, the waterproofing is weak or the water leakage concrete is not firmly poured. It could have happened. In addition, a separate induction drainage pipe was formed on the long formed cracks 10 to discharge water into the drainage. However, this method is also only a temporary treatment method. After 3 to 4 years, a white phenomena occurs and the drain pipe is clogged and water leaks on the wall. As a result, the size of the crack is gradually enlarged, which affects the stability of the structure. There was a problem.

본 발명은 상기한 종래의 방법과는 달리 근복적으로 누수를 차단할 수 있도록 한 방법에 관한 것으로 이하 앞선 지하철 구조물을 예로써 상술한다.The present invention relates to a method capable of blocking the leak in a different manner unlike the conventional method described above.

제2도는 본 발명에 의한 방수처리방법을 나타낸 도면이다.2 is a view showing a waterproofing method according to the present invention.

앞서 기술한 방수 쉬트지(4)의 손상으로 도시한 바와같이 상기 방수 쉬트지(4)와 콘크리트 구조물(8)사이의 공간(11)에 물이 고여있다가 콘크리트 구조물(8)에 균열이 발생하여 누수가 생기게 될때 본 발명의 방수처리공정은 다음과 같이 수행된다.As shown in the above-described damage of the waterproof sheet 4, water accumulates in the space 11 between the waterproof sheet 4 and the concrete structure 8 and cracks occur in the concrete structure 8. When the leakage occurs by the waterproofing process of the present invention is carried out as follows.

[제1공정][Step 1]

콘크리트 구조물(8)에 생긴 균열부(10,10A,10B)에 보오링코아드릴기(12)의 드릴(13)로 방수 쉬트지(4)직전까지 보오링하되 보오링부(#1∼#6)가 이루어지도록 천공한다.Boring the cracks 10, 10A, 10B in the concrete structure 8 with the drill 13 of the boring core drill machine 12 until just before the waterproof sheet 4, but the boring portions (# 1 to ##). 6) Drill to make it happen.

[제2공정][Step 2]

또한 콘크리트 구조물(8)의 균열부(10,10A,10B)이외의 거푸집의 이음부분에 의해 생긴 공간(11)을 찾아 보오링코아드릴기(12)를 이용하여 다수의 보오링부(#7등)가 이루어지도록 천공한다.In addition, a plurality of boring parts (# 7) by using a boring core drill machine 12 to find a space 11 formed by the joint part of the formwork other than the cracks 10, 10A, 10B of the concrete structure 8. And so on).

[제3공정][Step 3]

상기 균열부(10,10A,10B등)에 천공된 하나의 보오링부(#1)에 시멘트 혼합물을 주입시킨다.The cement mixture is injected into one boring portion # 1 drilled in the cracks 10, 10A, 10B, and the like.

[제4공정][Step 4]

상기 주입된 시멘트 혼합물이 방수 쉬트지(4)와 콘크리트 구조물(8) 사이의 "+"자형 돌출부에 의해 생긴 공간(11,유로)을 메우면서 보오링된 또다른 다수의 보오링부(#2∼#7)로 배출된다.Another plurality of boring portions (# 2) in which the injected cement mixture is bored while filling the space 11 (euro) formed by the "+" shaped projection between the waterproof sheet 4 and the concrete structure 8. To # 7).

[제5공정][Step 5]

상기 시멘트 혼합물의 주입 및 배출공정이 끝나면 보오링부(#1∼#7)를 니플로 막아 시멘트 혼합물을 경화시킨다.After the injection and discharge of the cement mixture is finished, the boring parts (# 1 to # 7) are blocked with a nipple to cure the cement mixture.

[제6공정][Step 6]

상기 공간(11,유로)에 주입된 시멘트 혼합물이 경화가 끝나면 막았던 니플을 제거한다.The cement mixture injected into the space 11 and the euro is removed after the hardening is finished.

[제7공정][Step 7]

마지막으로 상기 콘크리트 구조물(8)의 누수가 발생하는 균열부(10,10A,10B등)와 균열부이외의 거푸집 이음부분에 다수 천공된 보오링부(#1∼#7)를 시멘트몰탈로 도포하여 마감한다.Finally, a plurality of perforated boring parts (# 1 to # 7) are coated with cement mortar on the cracks (10, 10A, 10B, etc.) where the leakage of the concrete structure 8 occurs, and the formwork parts other than the cracks. To finish.

상술한 본 발명의 개략적인 방수처리공정을 제3도를 참조로 더욱 상세히 설명하면 다음과 같다.The detailed waterproof treatment process of the present invention described above will be described in more detail with reference to FIG.

제3도는 제2도의 콘크리트 구조물(8)에 발생한 균열부위를 전면에서 본 도면이다.3 is a front view of the cracks generated in the concrete structure 8 of FIG.

예를들어 콘크리트 구조물(8)의 전면벽체에 3곳의 균열부(10,10A,10B)가 발생하여 누수가 발생되었을 경우 보오링코아드릴기(12)로 균열부에 생긴 "+"자형의 돌출부마다 보오링작업을 수행하여 보오링부(#1∼#6)를 천공한다. (이때 방수 쉬트지(4)가 손상되지 않도록 방수 쉬트지(4)의 직전까지만 주의하여 보오링작업을 수행하여야 한다.) 또한 균열부 이외의 부분 즉, 거푸집의 이음부분에 생긴 "+"자형의 돌출부에도 보오링부(#7)를 만든다. 그러면 방수 쉬트지(4)와 콘크리트 구조물(8)의 외벽사이에 고여있는 물이 보오링부를 통해 배출되게 된다. 물이 거의 배출되면 본 발명에 의한 시멘트 혼합물을 그리우팅 주입기로 천공된 보오링부(#1)에 주입하면 제2도의 방수 쉬트지(4)와 콘크리트 구조물(8)의 외벽사이의 "+"자형 돌출부에 의해 형성된 공간(11,유로)으로 시멘트 혼합물이 채워지면서 손상된 방수 쉬트지(4)부위를 막거나 방수 쉬트지(4)가 떠있는 부위를 뚫고 들어가 공간(11,유로)과 방수 쉬트지(4) 및 콘크리트 구조물(8)을 긴밀히 접착시키게 된다. 그렇게 해서 물은 방수 쉬트지(4)를 침투하지 못하게 되는 것이다.For example, when three cracks 10, 10A, 10B occur on the front wall of the concrete structure 8 and leak occurs, the boring core drill machine 12 has a " + " A boring operation is performed for each protrusion to drill the boring portions # 1 to # 6. (At this time, boring should be carried out with care until just before the waterproof sheet 4 so that the waterproof sheet 4 is not damaged.) In addition, the "+" shape formed in the part other than the crack part, that is, the joint part of the formwork The boring part (# 7) is also made in the protrusion of. Then, water accumulated between the waterproof sheet 4 and the outer wall of the concrete structure 8 is discharged through the boring portion. When the water is almost discharged, the cement mixture according to the present invention is injected into the boring portion # 1 bored by the grouting injector, and the "+" between the waterproof sheet 4 and the outer wall of the concrete structure 8 of FIG. The space (11, euro) and the waterproof sheet are blocked by the cement mixture filled with the space (11, euro) formed by the male protrusions, or the damaged sheet (4) penetrates through the floating area. The paper 4 and the concrete structure 8 are closely bonded. In this way, the water does not penetrate the waterproof sheet 4.

그리고 그라우팅기의 주입압력에 의해 시멘트 혼합물은 콘크리트 구조물(8)의 외벽의 빈 틈새를 타고 밀려나와 주입된 시멘트 혼합물이 보오링부(#2,#5)에서 흘러나오게 된다. 이 경우 시멘트 혼합물을 제조시 물을 적게 사용하면 콘크리트 구조물(8)내의 틈에 남아있는 물과 시멘트 혼합물이 혼합되어 적당한 농도의 혼합물로 만들어진다. 즉, 보오링부(#2∼#7)에서 흘러나오는 시멘트 혼합물이 단초 혼합물의 농도와 같거나 유사한 경우 이는 상호 내통되어 콘크리트 구조물(8)과 방수 쉬트지(4)사이가 시멘트 혼합물로 꽉 채워졌다는 것을 나타내는 것이다. 그러면 천공된 보오링부(#1)의 끝부분을 니플로 막아둔다. 그리고 보오링부(#2)에 시멘트 혼합물을 주입하면 보오링부(#3과 #6)에서 상기와 같이 흘러나오고, 상기와 마찬가지로 보오링부(#3과 #6)에서 흘러나오는 시멘트 혼합물이 주입시의 시멘트 혼합물의 농도와 동일하거나 유사한 경유 보오링부(#2)를 니플로 체결한다. 이와 동일한 방법으로 시행하여 보오링부(#3∼#6)에 대하여도 니플로 체결한다. 그리고 재차 확인을 위해 에를들어 보오링부(#5)의 니플을 열어 다시 시멘트 혼합물을 주입하면서 보오링부(#6)에 체결된 니플을 열어본다. 상호 접착 즉, 틈새의 메워짐이 완료되었음이 확인되면 보오링부(#5)의 니플을 다시 잠근다. 마찬가지로 보오링부(#6)의 니플을 열어 다시 시멘트 혼합물을 재차 주입하면서 보오링부(#7)의 니플을 열어보아 틈새의 메워짐이 완료되었음이 확인되면 보오링부(#6)의 니플도 잠근다.The cement mixture is pushed through the empty gap of the outer wall of the concrete structure 8 by the injection pressure of the grouting machine so that the injected cement mixture flows out from the boring parts # 2 and # 5. In this case, if less water is used in the preparation of the cement mixture, the water and cement mixture remaining in the gap in the concrete structure 8 is mixed into a mixture of a suitable concentration. That is, when the cement mixture flowing out from the boring parts # 2 to # 7 is the same as or similar to the concentration of the initial mixture, it is intermingled with each other to fill the cement mixture between the concrete structure 8 and the waterproof sheet 4 tightly with the cement mixture. It indicates that you have lost. Then, the end of the perforated boring portion (# 1) is blocked with a nipple. When the cement mixture is injected into the boring part # 2, the cement mixture flows out from the boring parts # 3 and # 6 as described above, and the cement mixture flowing out of the boring parts # 3 and # 6 is formed as described above. Tighten the diesel boring part # 2 equal or similar to the concentration of the cement mixture at the time of injection. Implement in the same manner and tighten the nipples for the boring parts # 3 to # 6. And again to check for example by opening the nipple of the boring portion (# 5) while opening the nipple fastened to the boring portion (# 6) while injecting the cement mixture again. When it is confirmed that the mutual adhesion, that is, the filling of the gap is completed, the nipple of the boring portion # 5 is locked again. Likewise, when the nipple of the boring portion (# 6) is opened and the cement mixture is re-injected again, the nipple of the boring portion (# 7) is opened to confirm that the gap is completed and the nipple of the boring portion (# 6) is completed. Locks too.

그리고 일정시간이 지난 후 시멘트 혼합물이 완전히 경화되었다고 판단되면 상기의 니플들을 제거하고 보오링부위(#1∼#7)를 시멘트몰탈로 도포하여 마감한다.After a certain period of time, if it is determined that the cement mixture is completely cured, the nipples are removed and the boring parts (# 1 to # 7) are coated with cement mortar to finish.

이렇게 하여 누수보수를 요하는 전체면적에 걸쳐 방수처리가 완료된다.This completes the waterproofing over the entire area requiring leak repair.

이상과 같은 본 발명의 방수처리방법에 의하여 콘크리트 구조물(8)과 방수 쉬트지(4)사이의 공간(11,유로)과 그 균열부(10)의 모든 주변부에 그라우팅기의 주입압에 의해 시멘트 혼합물이 골고루 투입되어 완벽한 방수처리효과가 있을뿐만 아니라 시멘트 혼합물의 강도가 일반 시멘트의 강도보가 크므로 콘크리트 구조물 자체의 강도를 더욱 향상시킬 수 있는 뛰어난 효과가 있는 것이다.According to the waterproofing method of the present invention as described above, the cement mixture is injected into the space 11 between the concrete structure 8 and the waterproof sheet 4 by the injection pressure of the grouting machine in all peripheral portions of the crack 10. Not only is it evenly added, it has a perfect waterproofing effect, and the strength of the cement mixture is greater than that of general cement, so that the strength of the concrete structure itself can be further improved.

본 발명에 의한 누수차단 충진방법에 의하면 지하철 구조물뿐만 아니라 상가건물, 가정집등의 모든 콘크리트 구조물의 외벽에 방수 쉬트지로 방수한 부위에서 누수가 될 경우에 적용이 가능하다.According to the leak-blocking filling method according to the present invention can be applied to the case of water leakage from the waterproofing sheet on the outer wall of all concrete structures, such as mall buildings, homes, etc. as well as subway structures.
