Description

콘크리트수조의 배관부{Piping for a concrete a water tank}Piping for a concrete a water tank}

본 발명은 콘크리트수조의 배관부에 관한 것으로서, 더욱더 상세하게는 콘크리트수조의 내측 벽면에 방수 기능을 갖도록 배관파이프를 설치하는 것이 용이하게 이루어지도록 하는 콘크리트수조의 배관부에 관한 것이다.The present invention relates to a pipe of the concrete tank, and more particularly to a pipe of the concrete tank to facilitate the installation of the pipe pipe to have a waterproof function on the inner wall surface of the concrete tank.

일반적으로 저수조(貯水曹)는 일정량의 물을 저장하여 주거용 아파트 및 업무용 빌딩등과 같이 생활용수의 사용이 많은 건축물에 공급할 수 있도록 하는 것으로, 이러한 저수조는 스테인리스패널수조, SMC수조, FRP수조, PDF수조, 콘크리트수조 등과 같이 사용되는 재질에 따라 그 종류가 구분 된다.In general, a reservoir is a water tank that stores a certain amount of water so that it can be supplied to buildings that use a lot of water, such as residential apartments and business buildings.These tanks are stainless steel panel tanks, SMC tanks, FRP tanks, PDFs. Types are classified according to the materials used, such as tanks and concrete tanks.

이러한 저수조에 있어서, 상기 콘크리트수조의 경우에는 내부에 담겨있는 물이 외부로 누수되는 것을 방지하기 위하여 콘크리트 구조물의 시공을 완료한 후 내벽에 방수액을 2회이상 도포하게 되는데, 이러한 방수작업은 사방이 밀폐된 콘크리트저수조의 내부에서 이루어지게 됨으로서 작업자가 냄새등에 의해 작업을 수행시 불편함을 느끼게 되는 문제점이 있었다.In such a water tank, in the case of the concrete water tank, after the construction of the concrete structure is completed in order to prevent the water contained in the inside from leaking to the outside, the waterproofing solution is applied to the inner wall two or more times. By being made in the interior of the concrete reservoir, there was a problem that the worker feels uncomfortable when performing the work by smell.

한편, 상기와 같이 방수액이 도포되어 형성된 방수층이 일정 기간이 경과하여 손상이 발생하면, 상기 손상된 방수층의 위에 에폭시 페인트를 도장하여 방수 기능을 수행하도록 수질이 보호되도록 하고 있다.On the other hand, if a damage occurs after a certain period of time the waterproof layer is formed by applying the waterproofing liquid, the water quality is protected so as to perform the waterproof function by coating the epoxy paint on the damaged waterproof layer.

그러나 이러한 에폭시 페인트는 휘발성이 강한 수지로 조성되어 있어 그 유해성분으로 인해 작업중 호흡곤란을 유발시키고, 심한 경우에는 질식사를 유발시키게 되는 문제점이 있었다.However, these epoxy paints are composed of a highly volatile resin, causing harmful breathing during the operation due to its harmful components, and in severe cases, there is a problem of causing asphyxiation.

또한, 이러한 에폭시 페인트는 도막 부착력의 한계 때문에 단 기간 내에 내벽의 표면으로부터 이탈하는 박리현상이 발생하여 수질을 오염시키게 되는 결함이 있어 2~3년에 한번씩 재 도장작업을 하여야 하는 비 경제적인 문제점이 있었다.In addition, the epoxy paint has a defect that causes peeling from the surface of the inner wall within a short period of time due to the limitation of the adhesion of the coating film, and contaminates the water quality. there was.

한편, 상기 에폭시 페인트는 인체에 아주 유해한 환경호르몬인 비스페놀A가 함유되어 있어, 이러한 유해물질이 저수조에 담겨있는 물에 함유된 상태로 공급되어 인체에 소량이라도 축적되는 경우에는 건강에 악영향을 미치게 되는 문제점이 있었다.On the other hand, the epoxy paint contains bisphenol A, an environmental hormone that is very harmful to the human body, and when such harmful substances are supplied in the water contained in the water tank and accumulate even a small amount in the human body, it adversely affects health. There was a problem.

따라서 종래에도 상기와 같은 문제점을 해결하기 위해 도 1에 도시하고 있는 같이 콘크리트수조(100)의 내측 벽면에 폴리에틸렌시트(Polyethylene Sheet)(200)를 고정되게 설치하여 방수가 이루어지도록 하고 있다.Therefore, in order to solve the problems as described above, the polyethylene sheet 200 is fixedly installed on the inner wall surface of the concrete water tank 100 as shown in FIG.

그러나 상기 콘크리트수조(100)를 형성하고 있는 벽(110)과 폴리에틸렌시트(200)를 관통하도록 배관파이프(310)를 설치하는 경우, 상기 배관파이프(310)가 설치되어 있는 배관부(300) 주위로 누수가 발생하거나 콘크리트수조(100)의 외부에서 발생된 오염물질이 내부로 유입되어 수질을 오염시키게 되는 문제점이 있었다.However, when the pipe pipe 310 is installed to penetrate the wall 110 and the polyethylene sheet 200 forming the concrete water tank 100, the pipe 300 is installed around the pipe part 300. There is a problem in that water leakage or contaminants generated from the outside of the concrete water tank 100 is introduced into the inside to contaminate the water quality.

따라서 종래에는 상기 콘크리트수조(100)의 내부에 위치하고 있는 배관파이프(310)의 외측면을 감싸도록 실링재(320)를 설치하고, 상기 실링재(320)의 외측면에는 폴리에틸렌시트(200)와 같은 재질로 제작된 폴리에틸렌판넬(330)을 밴드(340)를 이용해 감싸도록 설치하며, 상기, 밴드(340)에 의해 실링재(320)의 외측면을 감싸고 있는 폴리에틸렌판넬(330)을 폴리에틸렌시트(200)에 열융착시켜 배관부(300) 주위가 방수되도록 하고 있다.Therefore, in the related art, a sealing material 320 is installed to surround the outer surface of the pipe pipe 310 located inside the concrete water tank 100, and the same material as the polyethylene sheet 200 is provided on the outer surface of the sealing material 320. The polyethylene panel 330 is manufactured to be wrapped using the band 340, and the polyethylene panel 330 surrounding the outer surface of the sealing material 320 by the band 340 is disposed on the polyethylene sheet 200. By heat fusion, the periphery of the pipe part 300 is waterproof.

그러나 이 역시도 상기 배관파이프(310)의 외측면을 실링재(320)가 감싸도록 밴드(340)를 이용해 폴리에틸렌판넬(330)을 설치하여야 함은 물론, 상기실링재(320)를 감싸고 있는 폴리에틸렌판넬(330)의 단부를 폴리에틸렌시트(200)에 열융착시켜야 함으로서, 콘크리트수조(100)에 배관부(300)를 설치시, 작업성이 증가하여 작업성을 저하시키게 됨은 물론, 상기 배관파이프(310)와 폴리에틸렌판넬(330)간에 틈새가 발생하는 경우에는 제대로 방수가 이루어지지 않아 상기 배관파이프(310)가 설치되어 있는 배관부(300) 주위로 누수가 발생하거나 콘크리트수조(100)의 외부에서 발생된 오염물질이 내부로 유입되어 수질을 오염시키게 되는 문제점이 있었다.However, this also needs to install the polyethylene panel 330 using the band 340 to surround the outer surface of the pipe pipe 310, the sealing material 320, as well as the polyethylene panel 330 surrounding the sealing material 320 By heat-sealing the end of the) to the polyethylene sheet 200, when installing the pipe portion 300 in the concrete water tank 100, the workability is increased to lower the workability, as well as the pipe pipe 310 and If a gap is generated between the polyethylene panels 330, water is not properly formed, and water leaks around the pipe part 300 in which the pipe pipe 310 is installed, or contamination generated from the outside of the concrete water tank 100. There was a problem that the material is introduced into the inside to contaminate the water quality.
