또한, 환경오염 문제를 야기하지 않고 보수작업 후에도 환경에 영향을 주지 않는 무용제형이고 불수용성인 보수재로 사용할 수 있는 제품의 개발이 필요하였다.In addition, it was necessary to develop a product that can be used as a solvent-free and insoluble repair material that does not cause environmental pollution problems and does not affect the environment even after repair work.

종래의 경우에는 상기와 같은 문제점을 해결하기위해 균열부위에 에폭시 수지를 투입하여 콘크리트 구조물의 균열을 보수 및 보강하는 방법을 제공하였다.In the related art, in order to solve the above problems, an epoxy resin is added to a crack to provide a method of repairing and reinforcing a crack of a concrete structure.

종래의 균열보수는 균열부확인단계, 이물질제거단계, 먼지청소단계, 실링단계, 패커설치단계, 균열보수재 주입단계, 패커제거단계, 및 씰링재 제거단계를 포함하였다.Conventional crack repairs included cracks identification step, foreign material removal step, dust cleaning step, sealing step, packer installation step, crack repair material injection step, packer removal step, and sealing material removal step.

상기 이물질제거단계는 균열부에 이물질을 제거하기 위해 균열부를 그라인딩하여 표면을 매끄럽게 하는 단계이다.The foreign material removal step is to smooth the surface by grinding the crack to remove the foreign matter in the crack.

상기 먼지청소단계는 상기 이물질제거단계에서 그라인딩하여 발생한 먼지를 제거하는 단계이다.The dust cleaning step is a step of removing dust generated by grinding in the foreign material removal step.

상기 씰링단계는 상기 균열부의 상부에 균열보수재 주입시 누수를 방지하기 위해서 씰링재를 설치하는 단계이다.The sealing step is a step of installing a sealing material to prevent leakage when the crack repair material is injected into the upper portion of the crack.

상기 패커설치단계는 상기 균열부에 균열보수재를 투입하기 위해서 균열부와 일정거리 떨어진 곳에서 경사지게 하부방향으로 패커구멍을 천공한 후 패커를 설치하는 단계이다.The packer installation step is a step of installing the packer after drilling the packer hole downwardly inclined at a predetermined distance away from the crack in order to inject the crack repair material to the crack.

상기 균열보수재 주입단계는 상기 패커설치단계에서 설치된 패커를 통해서 균열보수재 투입장치를 사용하여 상기 균열보수재를 상기 균열부에 투입하는 단계이다.The crack repair material injection step is a step of injecting the crack repair material to the crack portion by using a crack repair material input device through the packer installed in the packer installation step.

상기 패커제거단계는 상기 균열보수재를 투입하기 위해 상기 패커구멍에 패커를 설치한 상기 페커를 제거하는 단계이다.The packer removing step is a step of removing the pecker having a packer installed in the packer hole to inject the crack repair material.

상기 씰링제거단계는 상기 씰링단계에서 설치된 씰링재를 제거하는 단계이다.
The sealing removing step is to remove the sealing material installed in the sealing step.

종래의 균열보수방법을 철도 콘크리트 침목과 콘크리트 도상 사이에 발생한 균열부에 시행할 경우, 열차운행에 의한 진동으로 씰링재가 갈라지게 되고, 균열보수재가 갈라진 부분으로 유출되어 콘크리트 침목의 바닥과 측면 균열부를 메우기전에 주입이 완료가 되는 문제점이 있었다.When the conventional crack repair method is applied to the cracks generated between the railroad concrete sleepers and the concrete bed, the sealing material splits due to the vibration caused by the train operation, and the crack repair material leaks to the cracked parts, causing the bottom and side cracks of the concrete sleepers to break down. There was a problem that the injection is completed before filling.

또한, 빠른시간(약 3시간) 내에 작업을 마무리해야하는 철도 보수작업에서 씰링재를 사용함으로써, 상기 씰링재가 경화하기위해서 24시간 이상 지나야하기 때문에 철도 보수작업에 사용이 부적합한 문제점이 있었다.In addition, by using the sealing material in the railway repair work that must finish the work within a short time (about 3 hours), there is a problem that the use of the railway repair work because the sealing material has to pass more than 24 hours to cure.

또한, 상기 균열부의 상부에 씰링재를 설치함에 따라 균열보수재의 주입상태를 확인할 수가 없어, 균열보수재를 완벽하게 채워지지 않는 문제점이 있었다.In addition, as the sealing material is installed on the upper part of the crack, it is not possible to check the injection state of the crack repair material, and thus there is a problem in that the crack repair material is not completely filled.

이때, 상기 균열보수재를 상기 균열부에 완전히 채우더라도, 일정시간이 경과한 후에 미확인 균열부에 상기 균열보수재가 흘러들어가 상기 균열부를 채우지 못하는 문제점이 있었다.At this time, even if the crack repair material is completely filled in the crack portion, there is a problem that the crack repair material flows into the unidentified crack portion after a predetermined time has not filled the crack portion.

상기와 같은 문제점으로 인해 상기 균열보수재가 상기 균열부를 완전히 채우지 못해, 철도 균열보수 후에 재균열부가 발생되는 문제점이 있었다.
Due to the problems described above, the crack repair material did not completely fill the cracks, and there was a problem in that a crack crack was generated after railway crack repair.

본 발명은 상기와 같은 문제를 해소하려는 것으로, 더욱 상세하게 철도 콘크리트도상과 콘크리트침목 사이에 발생한 균열부를 보수할 경우, 보수시간을 단축시키고, 균열부에 재균열부가 발생되는 것을 방지하며, 균열부에 균열보수재가 완전히 채워지는 철도 콘크리트도상에 위치하는 콘크리트침목유동 방지를 위한 균열보수 방법을 제공하려는데 그 목적이 있다.

After replenishing the epoxy 70 in the epoxy replenishing step (S70) and the epoxy 70 is cured after a predetermined time, the pedestal 90 is removed.

또한, 상기 콘크리트도상(10)의 표면이 불규칙적으로 기울어져 있는 경우 상기 V컷팅부(50)에 상기 에폭시(70)를 전체적으로 채울 수가 없기 때문에 상기 에폭시(70)를 고점도 에폭시로 사용하여 상기 V컷팅부(50)에 상기 에폭시(70)가 채워지도록 한다.
In addition, when the surface of the concrete phase 10 is inclined irregularly, the V-cutting part 50 cannot fully fill the epoxy 70, so that the V-cutting is performed using the epoxy 70 as a high viscosity epoxy. The epoxy 50 is filled in the portion 50.

따라서, 본 발명의 철도 콘크리트도상에 위치하는 콘크리트침목유동 방지를 위한 균열보수 방법은 씰링재를 설치하지 않아 상기 균열부(40)를 보수하는 시간을 단축시키고, 상기 균열부(40)의 상부에 상기 V컷팅부(50)를 형성하여 상기 균열부(40)에 상기 에폭시(70)가 채워지는 것을 확인할 수 있으며, 상기 V컷팅부(50)를 통해 부족한 상기 에폭시(70)를 보충할 수 있어 상기 균열부(40)에 상기 에폭시(70)를 완전히 채울 수 있어 재균열부가 발생되는 것을 방지할 수 있다.
Therefore, the crack repair method for preventing the flow of concrete sleepers located on the railway concrete diagram of the present invention shortens the time for repairing the cracks 40 by not installing a sealing material, and the upper part of the cracks 40. It can be confirmed that the epoxy 70 is filled in the cracks 40 by forming the V-cutting part 50, and the epoxy 70 that is insufficient through the V-cutting part 50 can be replenished. The epoxy 70 may be completely filled in the crack 40, thereby preventing the recracking portion from occurring.
