본 발명은 균열보수공법에 관한 것으로, 보다 상세하게는 콘크리트 구조물에 발생된 균열부분을 보다 신속하고 완벽하게 보수할 수 있는 균열보수공법에 관한 것이다.The present invention relates to a crack repair method, and more particularly to a crack repair method that can repair the cracks generated in the concrete structure more quickly and completely.

일반적으로 콘크리트 구조체는 콘크리트의 건조와 수축, 온도변화, 누수, 진동 등 여러 요인에 의해 외부 또는 내부에 균열이 발생될 가능성이 매우 높으며, 차량이나 열차의 통행이 많은 터널, 지하철의 차량 통로에는 진동 등의 여러 요인에 의해 균열이 빈번하게 발생된다.In general, concrete structures are highly likely to be cracked on the inside or outside due to various factors such as drying and shrinking of concrete, temperature change, water leakage, and vibration. Cracks frequently occur due to various factors.

이러한 콘크리트의 균열 부분은 외부의 수분 및 공기의 유입이 쉽게 이루어지므로 콘크리트의 풍화를 촉진하고, 철근의 부식을 초래하여 콘크리트 구조물의 수명 및 안전성에 치명적인 악영향을 미치게 된다.The cracked portion of the concrete facilitates the inflow of external moisture and air, thereby promoting the weathering of the concrete, causing corrosion of the reinforcing bar, which has a fatal adverse effect on the life and safety of the concrete structure.

따라서 이와 같은 균열이 발생된 콘크리트 구조물은 통상적으로 팩커(Packer)를 이용하여 균열부분에 애폭시나 시멘트혼화제 등의 보수제를 충진시키므로 균열을 보수하였다.Therefore, a concrete structure in which such a crack is generated is usually repaired by using a packer (Packer) to fill a crack with a repair agent such as an epoxy or cement admixture.

도 1은 이러한 종래의 균열보수공법을 나타낸 도면으로, 도시된 바와 같이 균열부분(CR)이 발생된 콘크리트 구조물(CS)에 구멍(H)을 드릴 등으로 형성하고, 구멍(H)에는 팩커(10)를 삽입하며, 균열부분(CR)은 실링테이프(S)나 에폭시수지 등을 사용하여 실링하게 된다. 따라서 균열부분(CR)은 팩커(10)로부터 주입되는 보수제로 인해 점진적으로 충진되어 보수하게 된다.1 is a view showing such a conventional crack repair method, as shown in the hole (H) is formed in the concrete structure (CS) in which the crack portion (CR) is generated, such as by drilling, and the packer (H) in the hole (H) 10) Insert the crack portion CR is sealed using a sealing tape (S) or epoxy resin. Therefore, the crack CR is gradually filled and repaired by the repair agent injected from the packer 10.

그러나 이와 같은 종래의 균열보수공법은 균열 내부의 습한 상태 등을 고려하지 않고 균열 표면의 건조된 상태만을 고려하여 보수작업을 진행하게 된다. 따라서 충진되는 보수제는 콘크리트 구조물(CS)과 정상적으로 접착되지 아니하거나 상당시간 소요되므로 부실한 보수작업의 원인이 되었다.However, the conventional crack repair method proceeds with the repair work only considering the dried state of the crack surface without considering the wet state inside the crack. Therefore, the refilling agent is not properly bonded with the concrete structure (CS) or takes a considerable time, causing the poor repair work.

또한 종래의 균열보수공법은 균열 내부의 미세한 콘크리트 가루와 같은 이물을 제거하지 않은 상태에서 보수액을 충진시키므로 보다 세밀하게 균열부분(CR)에 보수제를 충진시킬 수 없었다. 따라서 보수제가 침투되지 않은 균열부분(CR)은 진동 등의 요인에 의해 재균열이 발생되었으며, 이로 인하여 균열보수작업에 대한 신뢰도를 크게 실추시키는 문제점이 있었다.In addition, in the conventional crack repair method, the repair solution is filled in a state in which foreign substances such as fine concrete powder in the crack are not removed, and thus the repair agent cannot be filled in the cracks CR more precisely. Therefore, cracks (CR) that did not penetrate the repair agent were re-cracked due to factors such as vibration, and thus there was a problem that greatly degraded the reliability of crack repair work.

본 발명은 전술한 바와 같은 종래의 제반 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 균열내부의 환경을 균열표면과 같이 건조한 상태로 만든 후 보수액을 충진시키므로 보다 완벽하고 신속한 보수작업이 이루어질 수 있도록 하는 균열보수공법을 제공하는 데 있다.The present invention has been made in order to solve the conventional problems as described above, the object of the present invention is to make a more complete and quick repair work to fill the repair liquid after making the environment inside the cracks dry as the crack surface It is to provide a crack repair method to make it possible.

본 발명의 또 다른 목적은 균열 내부의 이물질 등을 제거한 후 보수액을 충진시키므로 보다 완벽하고 견고한 보수작업이 이루어질 수 있도록 하는 균열보수공법을 제공하는 데 있다.Still another object of the present invention is to provide a crack repair method for removing a foreign material in the crack and then filling the repair liquid so that a more complete and solid repair work can be performed.

이와 같은 목적을 달성하기 위한 본 발명의 균열보수공법은 콘크리트 구조물의 균열 부분에 팩커를 충진시켜 균열 부분을 보수하는 공법에 있어서, 팩커를 설치하기 위하여 균열부분에 구멍을 형성하는 천공단계와; 균열부분을 실링하는 실링단계와; 상기 구멍에 팩커를 삽입 설치하는 팩커설치단계와; 일부 팩커를 통해 압축공기를 주입하여 균열부분의 이물질, 물, 습기 등을 외부로 배출시켜 제거하는 압축공기주입단계와; 일부 팩커를 통해 이물질과 수분이 제거된 균열부분에 보수제를 주입하는 보수제주입단계와; 보수제의 주입이 완료된 이후 보수제를 경화시키는 보수제경화단계와; 콘크리트 구조물의 표면에서 돌출된 팩커를 제거하는 팩커제거단계와; 보수작업이 이루어진 콘크리트 구조물의 표면을 마감하는 마감단계로 이루어지는 것을 특징으로 한다.The crack repair method of the present invention for achieving the above object is a method for repairing the crack portion by filling the packer in the cracked portion of the concrete structure, the drilling step of forming a hole in the cracked portion to install the packer; A sealing step of sealing the crack portion; A packer installation step of inserting and installing a packer in the hole; Compressed air injection step of injecting compressed air through some packers to remove the foreign matter, water, moisture, etc. in the crack portion to the outside to remove; A repair agent injection step of injecting a repair agent into the cracked portion from which foreign substances and water are removed through some packers; A repair agent curing step of curing the repair agent after the injection of the repair agent is completed; A packer removing step of removing the packer protruding from the surface of the concrete structure; Characterized in that it is made of a finishing step of finishing the surface of the concrete structure is repaired.

이하, 본 발명의 균열보수공법에 따른 실시예를 보다 상세하게 설명하면 다음과 같다.Hereinafter, an embodiment according to the crack repair method of the present invention will be described in detail.

도 2는 본 발명에 따른 균열보수공법을 나타낸 블록도이고, 도 3a 내지 도 3h는 본 발명에 따른 균열보수공법의 각 단계를 나타낸 단면도로서, 도시한 바와 같이 본 발명의 균열보수공법은 크게 천공단계, 실링단계, 팩커설치단계, 압축공기주입단계, 보수제주입단계, 보수제경화단계, 팩커제거단계, 마감단계로 이루어진다.Figure 2 is a block diagram showing a crack repair method according to the present invention, Figures 3a to 3h is a cross-sectional view showing each step of the crack repair method according to the present invention, as shown in the crack repair method of the present invention largely perforated It consists of the step, sealing step, packer installation step, compressed air injection step, repair agent injection step, repair agent hardening step, packer removal step, finishing step.

먼저, 천공단계는 도 3a에서 도시한 바와 같이 팩커(100)를 설치하기 위하여 균열 부분이 발생된 콘크리트 구조물(CS)의 표면에 구멍(H)을 형성하는 단계로서, 균열부분(CR)의 길이와 깊이 등을 고려하여 일정한 간격으로 형성한다.First, the drilling step is to form a hole (H) in the surface of the concrete structure (CS) in which the crack was generated in order to install the packer 100, as shown in Figure 3a, the length of the crack (CR) Form at regular intervals considering the depth and depth.

실링단계는 도 3b에서 도시한 바와 같이 균열부분(CR)을 기밀시키기 위한 단계로서, 실링테이프(S)를 사용하여 균열부분(CR)을 실링하거나 에폭시수지 등으로 실링할 수 있으며, 또한 에폭시수지 등으로 실링한 이후, 그 위에 실링테이프(S)를 부착하므로 균열부분(CR)을 통한 공기나 보수제의 외부 유출을 방지할 수 있다.The sealing step is a step for sealing the cracks CR as shown in FIG. 3B. The cracks CR may be sealed or epoxy resins may be sealed using a sealing tape S. After sealing with the sealing tape, the sealing tape (S) is attached thereon so that the outflow of air or the repair agent through the crack (CR) can be prevented.

팩커설치단계는 도 3c에서 도시한 바와 같이 천공단계를 통해 형성된 구멍(H)에 팩커(100)를 삽입 설치하는 단계로서, 이러한 팩커설치단계에 사용되는 팩커(100)는 공기주입구(110)와 보수액주입구(120)가 마련된 것을 사용하여 공기의 주입과 보수제(400)를 선택적으로 주입할 수 있도록 한다.Packer installation step is a step of inserting the packer 100 into the hole (H) formed through the drilling step as shown in Figure 3c, the packer 100 used in the packer installation step is the air inlet 110 and By using the repair liquid inlet 120 is provided to be able to selectively inject the air and the repair agent 400.

압축공기주입단계는 도 3d에서 도시한 바와 같이 팩커(100)를 통해 압축공기를 균열부분(CR)에 주입하는 단계로서, 일부 팩커(100)의 공기주입구(110)에 공기 펌프의 공기주입호스(200)를 연결하므로 압축공기를 주입한다. 따라서 균열부분(CR)의 이물질, 물, 습기 등은 공기주입이 이루어지지 않는 다른 팩커(100)의 공기주입구(110)를 통해 외부로 배출되고, 균열부분(CR)은 이물질과 수분이 제거된 청결하고 건조한 상태로 변화된다. 그리고 압축공기의 주입은 이물질이나 물기 또는 습기 등이 더 이상 배출되지 않을 때까지 지속한다.Compressed air injection step is to inject the compressed air into the crack portion (CR) through the packer 100 as shown in Figure 3d, the air injection hose of the air pump in the air inlet 110 of some packers 100 Inject the compressed air so as to connect the (200). Therefore, foreign matter, water, moisture, etc. of the crack portion CR are discharged to the outside through the air inlet 110 of the other packer 100, which is not air injection, the crack portion CR is the foreign matter and water is removed It changes to a clean and dry state. The injection of compressed air continues until no more foreign matter, water or moisture is released.

보수제주입단계는 도 3e에서 도시한 바와 같이 균열부분(CR)에 보수제(400)를 주입하는 단계로서, 보수제(400)의 주입은 팩커(100)의 보수제주입구(120)에 보수제공급호스(300)를 연결하므로 보수제(400)를 주입하게 된다.The repair agent injection step is a step of injecting the repair agent 400 into the crack portion CR as shown in FIG. 3E, and the injection of the repair agent 400 is a repair agent supply hose 300 to the repair agent inlet 120 of the packer 100. ) So that the repair agent 400 is injected.

따라서 보수제(400)는 이미 압축공기주입단계를 통해 깨끗하고 건조된 상태로 변화된 균열부분(CR)의 깊숙한 부분까지 주입되고 또한 균열부분(CR)의 벽면에 밀착 경화된다. 그리고 보수제(400)의 주입은 보수제(400)가 주입되지 않는 팩커(100)를 통해 보수제(400)가 외부로 유출될 때까지 주입한다. Therefore, the repair agent 400 is injected into the deep part of the crack part CR, which has already been changed to a clean and dried state through the compressed air injection step, and is also hardened in close contact with the wall surface of the crack part CR. And the injection of the repair agent 400 is injected until the repair agent 400 flows out through the packer 100 in which the repair agent 400 is not injected.

보수제경화단계는 도 3f에서 도시한 바와 같이 주입이 완료된 보수제(400)를 일정시간 동안 경화시키는 단계로서, 팩커(100) 외부로 보수제(400)가 유출되면, 보수제(400)의 주입은 중지하고 보수제(400)가 유출되는 팩커(100)에는 캡(130)을 씌워 일정시간 동안 주입 완료된 보수제(400)를 경화시킨다.The repair agent curing step is a step of curing the repair agent 400 in which injection is completed, as shown in FIG. 3F, for a predetermined time. When the repair agent 400 flows out of the packer 100, the injection of the repair agent 400 is stopped. The packer 100 in which the repair agent 400 flows out is covered with a cap 130 to cure the repair agent 400 that has been injected for a predetermined time.

팩커제거단계는 도 3g에서 도시한 바와 같이 보수제(400)주입에 따라 콘크리트 구조물(CS)의 표면에서 돌출된 보수제(400)와 팩커(100)를 제거하는 단계이다.The packer removing step is a step of removing the repairing agent 400 and the packer 100 protruding from the surface of the concrete structure CS in accordance with the injection of the repairing agent 400 as shown in FIG. 3G.

마감단계는 도 3h에서 도시한 바와 같이 보수작업이 이루어진 콘크리트 구조물(CS)의 표면을 그라인딩 등을 통하여 표면을 깔끔하게 정리하는 단계이다.The finishing step is a step of neatly arranging the surface by grinding the surface of the concrete structure (CS) that has been repaired, as shown in Figure 3h.

이와 같이 본 발명의 균열보수공법은 도 3d에서 도시한 바와 같이 압축공기주입단계를 통해 균열부분(CR)에 압축공기를 불어 넣으므로 균열부분(CR)의 내부에 남아있는 콘크리트 가루나 이물질 물기 등을 외부로 배출시켜 소거하게 된다.As described above, the crack repair method of the present invention blows compressed air into the crack part CR through the compressed air injection step as shown in FIG. It is discharged to the outside and erased.

따라서 균열부분(CR)은 이물질이 없는 청결한 상태와 수분이 거의 제거된 건조한 상태를 갖게 되므로 이후 도 3e에서 도시한 바와 같이 주입되는 보수제(400)는 균열부분(CR)의 깊숙한 부분까지 주입되어 균열부분(CR)을 완벽하게 충진하게 되고, 또한 균열부분(CR)의 벽면에 견고하게 밀착 경화되어 고품질의 보수작업을 실현할 수 있게 된다.Therefore, since the crack portion CR has a clean state with no foreign matter and a dry state where water is almost removed, the repair agent 400 injected as shown in FIG. 3E is injected into the deep portion of the crack portion CR and cracked. The part CR is completely filled, and it is hardly adhered and hardened to the wall surface of the crack part CR, thereby realizing high quality repair work.

더욱이 본 발명의 균열보수공법은 팩커(100)의 외부로 배출되는 이물질이나 물기 등을 시각적으로 확인할 수 있으므로 균열부분(CR)의 내부 상태를 직접 유관으로 확인하지 않고도 그 상태를 파악할 수 있으며, 이로 인하여 공기주입단계를 적정한 시간동안 진행할 수 있다.Moreover, the crack repair method of the present invention can visually check foreign substances or moisture discharged to the outside of the packer 100, so that the state of the cracks CR can be grasped without directly checking the internal state of the cracks CR. Therefore, the air injection step can proceed for a suitable time.

그리고 본 발명의 균열보수공법은 팩커(100)의 외부로 배출되는 보수제(400)를 시각적으로 확인할 수 있으므로 균열부분(CR)의 내부 상태를 직접 유관으로 확인하지 않고도 균열부분(CR)에 보수제(400)가 완전하게 채워졌는지 그 상태를 파악할 수 있으며, 이로 인하여 전반적인 보수작업을 신속하고 용이하게 진행할 수 있다.In addition, the crack repair method of the present invention can visually confirm the repair agent 400 discharged to the outside of the packer 100, so that the repair agent may be repaired to the crack portion CR without directly checking the internal state of the crack portion CR. It is possible to determine whether the 400 is completely filled, thereby making the overall maintenance work quick and easy.
