반응성 수지를 이용한 관거 갱생 도포물층{Material layer by spread for pipe renewal using reactivity resin}Material layer by spread for pipe renewal using reactivity resin

상하수도는 일상생활에서 꼭 필요한 기반시설일 뿐만 아니라 건강상에도 큰 영향을 미치게 된다. 수도가 널리 보급되면서 장티푸스, 이질, 콜레라 등의 전염병을 비롯한 각종 질병이 크게 감소하였다. Water and sewage are not only necessary infrastructure in daily life but also have a great impact on health. As the capital became widespread, various diseases including infectious diseases such as typhoid fever, dysentery and cholera were greatly reduced.

상수도관은 그 내부를 물이 상용수압 4~10kg/cm2의 매우 빠른 유속으로 계속 흐르기 때문에 관로 내부 표면에 도포된 실링재가 몇 개월만 지나면 유실되며, 관로의 표면이 물에 노출된 상태에서 공기중의 탄산가스나 수돗물 중에 있는 염소이온(Cl-) 또는 가압수로 흐르는 물 등에 접촉됨으로서 수산화칼슘의 용출과 화학반응에 의해서 수소 이온농도(pH)가 높아지면 스케일이 생성되고, 스케일이 발생되면 스케일에 의해서 철의 체적이 2.5배 팽창하므로 관로 내부에 도포된 스케일방지 물질의 균열과 파괴를 야기하게 된다.Water pipes continue to flow through the water at a very high flow rate of 4 ~ 10kg / cm 2 , so that the sealing material applied to the inner surface of the pipeline is lost after a few months, and the surface of the pipeline is exposed to water. of carbon dioxide gas or chloride ions (Cl -) in the water at elevated when the hydrogen ion concentration (pH) by the dissolution or chemical reaction of the calcium hydroxide by being in contact pressure can be in water or the like flowing to the scale is generated, and scale the generated scale As the volume of iron expands 2.5 times, it causes cracking and destruction of the anti-scaling material applied inside the pipeline.

앞에서 설명한 것처럼 일정 기간이 지나면 수도관의 내부에 녹 및 마멸이 발생하여 수돗물에서 악취와 독성이 검출되어 음용수에 심각한 문제를 초래하기 때문에 일반적으로 일정한 시간이 되면 매설된 수도관 교체 작업을 해야 함으로서 많은 장비와 인력이 소요되고 공사기간이 길어져서 수도를 장시간 차단하여야 하는 불편이 가중되는 문제점이 있었다.As described above, after a certain period of time, rust and abrasion occurs inside the water pipes, and odors and toxicities are detected in tap water, which causes serious problems in drinking water. There was a problem that the inconvenience of having to cut off the water for a long time due to the manpower is required and the construction period is long.

일정 기간이 지나면 수도관의 내부에 녹 및 마멸이 발생하여 수돗물에서 악취와 독성이 검출되어 음용수에 심각한 문제를 초래하기 때문에 일반적으로 일정한 시간이 되면 매설된 수도관 교체 작업을 해야하는데, 최근에는 노후된 관을 교체하지 않고 갱생시키기 위한 공법으로 시멘트 몰탈 라이닝 공법, 폴리에틸렌 라이닝 공법, 에폭시 라이닝 공법 등이 있다.After a certain period of time, rust and abrasion occurs inside the water pipes, and odors and toxicities are detected in tap water, which causes serious problems in drinking water.In general, it is necessary to replace buried water pipes at a certain time. Cement mortar lining method, polyethylene lining method, epoxy lining method and the like for rehabilitation without replacement.

시멘트 몰탈 라이닝 공법은 가장 많이 사용되는 공법인데 관내부의 이물질을 제거하는 세관작업 후에 미리 반죽된 시멘트 몰탈을 분사한 후에 건조공정을 거쳐 강도가 높은 시멘트 몰탈 라이닝을 내부에 형성시키는 공법으로, 구조적인 보강효과가 있어 핀홀 등이 발생된 관체에도 적용이 가능하고, 상대적으로 오랜 경험과 실적이 있어 신뢰성이 높으며, 부식을 방지하고 습윤면에서도 시공이 가능한 장점이 있다. 그러나, 상기 시멘트 몰탈 라이닝 공법은 분사 후 경화 및 양생기간이 장시간 소요되어 단수시간이 길어지고, 소구경관에서는 마무리가 어려우며, 라이닝 두께에 따라 통수능력의 차이가 있고, 라이닝 작업 시에 기존 누수공으로 칩입수가 계속 침투할 경우 시공이 곤란한 문제점이 있었다.Cement mortar lining method is the most widely used method. After the customs work to remove foreign substances inside the pipe, the cement mortar lining is pre-kneaded and then dried to form a high strength cement mortar lining. It is effective, so it can be applied to the pipes where pinholes are generated. However, the cement mortar lining method takes a long time due to the hardening and curing period after spraying is long, it is difficult to finish in a small diameter tube, there is a difference in the water permeability according to the thickness of the lining, chipped into the existing leak hole during the lining work If the water continues to penetrate the construction was difficult.

폴리에틸렌 라이닝 공법은 고밀도 폴리에틸렌의 특성을 이용하여 관체 팽창공정을 개량화 한 기술로서 기존관 내부에 삽입시켜, 증기와 고압 공기의 압송을 통해 폴리에틸렌 파이프를 확대하여 융착 접합시키는 공법으로써, 구조적 보강효과 가 있어 핀홀 등이 발생된 관체에도 적용이 가능하고 수명이 매우 긴 장점이 있다. 그러나, 폴리에틸렌 라이닝 공법은 분기관 및 45°이상의 곡관 등은 굴착시공을 시행하여야 하고, 공법 중 가장 고가임으로 소구경관 같은 경우 신관 교체비용과 거의 같으며, 동절기에는 열에 의한 융착이 쉽지 않아 시공의 어려움이 있다.The polyethylene lining method is a technology that improves the expansion process of pipes by using the characteristics of high density polyethylene. It is a method of inserting the inside of an existing pipe and expanding and fusion-bonding the polyethylene pipe through the pressure of steam and high pressure air. It can be applied to the tube where pinholes are generated and has a very long service life. However, the polyethylene lining method requires excavation construction for branch pipes and curved pipes with 45 ° or more, and is the most expensive method in the case of small diameter pipes, which is almost the same as the cost of fuse replacement, and difficult to install due to heat fusion in winter. There is this.

에폭시 라이닝 공법은 관 내부에 이물질을 제거하는 세관작업 후에 에폭시와 경화제를 적당한 점도를 가진 액상 에폭시 수지로 혼합하여 분사헤드를 통하여 관 내부 표면에 고속의 원심력 분사로 도막을 관로의 내부에 형성하는 것으로, 공사비가 저렴하고, 공사기간이 짧으며 곡관 및 분사관 등에도 시공이 가능하며 통수능력의 차이가 거의 없는 장점이 있다. 그러나. 에폭시 라이닝 공법은 완전 건조되지 않는 상태에서 도장할 경우 경화제에 함유된 "아민" 성분이 수돗물에 용출되며, 그 독성으로 인해 인체에 해가 될 수 있으며, 대구경관에는 분사노즐의 분사력 차이로 인해 균일한 도막이 형성되기 곤란하여 적용이 어렵고, 에폭시 도장 후에 핀홀 발생 가능성으로 인해 도막이 탈거될 수 있는 문제점이 있다.Epoxy lining method is to mix the epoxy and hardener with liquid epoxy resin with proper viscosity after the customs work to remove foreign substances in the pipe and form the coating inside the pipe by high-speed centrifugal force injection through the spray head to the inner surface of the pipe. In addition, the construction cost is low, the construction period is short, construction can be performed on curved pipes and spray pipes, etc., and there is almost no difference in water supply capacity. But. Epoxy lining method, when applied in a state that is not completely dry, the "amine" component contained in the curing agent is eluted in the tap water, it may be harmful to the human body due to its toxicity, and large diameter tube uniformity due to the difference in the spraying force of the nozzle Since one coating is difficult to form, it is difficult to apply, and there is a problem in that the coating can be removed due to the possibility of pinhole generation after epoxy coating.

일정 기간이 지나면 수도관은 그 내부에 녹과 마멸이 발생하여 수돗물에서 악취와 독성이 검출되어 음용수에 심각한 문제를 불러 일으키기 때문에 일반적으로 일정한 시간이 경과되면 매설된 수도관 교체 작업을 해야 함으로서 많은 장비와 인력이 소요되고 공사기간이 길어져서 수도를 장시간 차단하여야 하는 불편이 가중되는 문제점이 있는데, 본 고안에서는 저점도의 반응성 MMA수지를 이용한 도장으로 관의 내부에 도포물층을 형성함으로서 작업시간을 크게 단축할 뿐만 아니라, 뛰어난 내구성으로 인해 유지 보수기간을 크게 늘림으로서 경제적 손실을 감소시키고자 한다.After a certain period of time, the water pipes are rusted and worn out, and odors and toxicities are detected in tap water, which causes serious problems in drinking water.In general, the pipes need to be replaced after a certain period of time. This is a problem that the inconvenience of having to cut off the water for a long time due to the long construction period is increased, in the present invention by forming a coating layer in the interior of the tube by using a low-viscosity reactive MMA resin significantly reduce the working time In addition, due to its excellent durability, it is intended to reduce the economic loss by greatly increasing the maintenance period.

Minimized, and durability is greatly increased compared to the existing construction method, economical by frequent repair and reconstruction It is to provide a conduit regeneration coating layer using a reactive resin that can reduce the loss.
