Description

폴리에틸렌 라이닝 보수관용 융착보수패드{A melting-repair-pad for liner repair-pipe}Fusion repair pad for polyethylene lining repair pipe {A melting-repair-pad for liner repair-pipe}

본 고안은 폴리에틸렌 라이닝 보수관용 융착보수패드에 관한 것으로, 융착보수패드에 있어서, 보수패드의 융착 접합면에 용융히터가 매설된 융착용융판를 분리 구비하여서 융착보수패드의 시공과정에 있어 보스패드의 과도한 용융으로 인한 보수불량 및 보수패드의 내구성 향상시킬 수 있도록 함을 목적으로 한 것이다.The present invention relates to a fusion repair pad for a polyethylene lining repair pipe, wherein the fusion repair pad is provided with a fusion plate having a molten heater embedded in the fusion joint surface of the repair pad, so that the boss pad is excessive in the construction of the fusion repair pad. Its purpose is to improve the durability of the repair and repair pads due to melting.

일반적으로, 상수관은 주로 철관으로 이루어져 있어 일정기간 사용하게 되면 부식이 발생하여 녹물이 발생하고 스케일이 형성되며 통수단면적의 축소로 인한 이상 압력으로 인하여 이음부로 누수가 발생하는 2 차적인 피해와, 정수처리된 수돗물의 누수로 인한 경제적 손실이 크게 발생하여 노후 수도관을 새로운 수도관으로 교체시공하고 있다.In general, the water pipe is mainly composed of steel pipes, and if it is used for a certain period of time, corrosion occurs, green water is generated, scales are formed, and secondary damage occurs in the joint due to abnormal pressure due to the reduction of the communication area. Due to the large economic loss caused by the leakage of purified tap water, old water pipes are replaced with new water pipes.

또한, 하수관은 주로 콘크리트관으로 이루어져 있어 일정기간 사용하게 되면 잦은 공사와 지상에서 가해지는 중차량의 활하중으로 인하여 균열 파손되어 하수의 누수로 인한 지하수의 오염 또는 지하수의 유입으로 인한 하수가 증대되므로 지면을 굴착한 후 이를 새로운 관을 교체 사용하고 있다.In addition, sewage pipes are mainly composed of concrete pipes, so if they are used for a certain period of time, they are cracked and damaged due to frequent construction and live loads of heavy vehicles applied on the ground, resulting in increased sewage due to groundwater contamination due to leakage of sewage or inflow of groundwater. After the excavation, it is used to replace the new pipe.

상기한 바와 같이 지하에 매설된 상수관과 하수관의 교체를 위하여는 많은 비용이 소요되는 문제점이 있어, 노후된 수도관과 하수관 내부의 부식물 및 스케일 등과 같은 불순물을 제거한 후 폴리에틸렌 라이너를 집어넣고 고온의 증기와 압축공기로 팽창 밀착시켜서 라이닝하는 라이닝법에 의하여 노후 수도관과 하수관을 폴리에틸레 라이너로 보수하여 사용하고 있다.As described above, there is a problem in that it is expensive to replace the water and sewage pipes buried underground, and after removing impurities such as decay and scales in the old water pipes and sewage pipes, a polyethylene liner is inserted and hot steam and The old water pipe and sewage pipe are repaired with a polyethylene liner by a lining method in which the lining is expanded and compressed by compressed air.

한편, 상기한 바와 같이 노후관에 폴리에틸렌 라이너를 집어넣는 과정에 있어 상기 라이너가 관내벽과의 마찰에 의하여 손상되는 사례가 발생하고 이상과 같이 손상된 상태에서 작업을 실시하게 되면 손상부위로 누수가 발생되고 라이너가 관체의 내벽에 밀착되지 못하며 관의 부식이 계속하여 진행되게 되는 등의 문제점이 있어, 도 1 에 도시된 바와 같이 폴리에틸렌 라이너와 동질의 폴리에틸렌 판상으로 이루어진 보수패드(210)와 상기 보수패드의 융착 접하면 측에 매설되어 상기 융착 접합면이 라이너에 융착되게하는 용융히터(220)로 구성한 융착보수패드가 개발되어 사용되었다.Meanwhile, in the process of inserting the polyethylene liner into the old pipe as described above, the liner is damaged by friction with the inner wall of the pipe. There is a problem that the liner is not in close contact with the inner wall of the tube and the corrosion of the tube continues to progress, such as the repair pad 210 and the repair pad made of a polyethylene plate of the same quality as the polyethylene liner as shown in FIG. A fusion repair pad has been developed and used, which is composed of a fusion heater 220 which is embedded at the side of the fusion contact and the fusion bonding surface is fused to the liner.

그러나, 상기한 바와 같은 종래의 융착보수패드는 보수패드의 융착 접합면에 용융히터(220)가 매설된 상태로 형성되어 있어 융착을 위한 융착 접합면의 가열용융과정에 있어 보수패드(210)의 융착 접합면 뿐 아니라 보수패드가 전체적으로 용융되어 흘러 내리거나 보수패드가 얇아져 그 내구성이 떨어지는 등의 문제점이 있었다.However, the conventional fusion repair pad as described above is formed in the state in which the melt heater 220 is embedded in the fusion bonding surface of the repair pad, the heating pad of the repair pad 210 in the heat melting process of the fusion bonding surface for fusion welding; Not only the fusion joint surface but also the maintenance pad melted down as a whole, or the maintenance pad was thin, there was a problem such that its durability is poor.

또한, 종래의 보수패드는 매설된 용융히터의 매설 깊이 등의 문제로 그 두께가 두껍게 형성되어 제조원가가 상승되고 관내에서 유속저하를 유발하는 문제점이 있었다.In addition, the conventional maintenance pad has a problem that the thickness is formed thick due to the embedding depth of the embedded melt heater, such that the manufacturing cost is increased and the flow rate decreases in the tube.

이에, 본 고안은 상술한 바와 같이 종래 융착보수패드가 용융 융착과정에 있어, 용융히터에 의하여 과도하게 용융되어 흘러내리거나 보수패드의 두께가 얇아져 내구성이 떨어지는 등의 보수불량이 발생하는 문제점과, 매설된 용융히터로 인하여 보수패드가 두껍게 형성되어 제조원가가 상승하고 관내에서 유속저하를 유발하는 문제점을 해결할 수 있도록 한 것이다.Accordingly, the present invention is a problem in that the conventional fusion repair pad in the melt fusion process, such as a poor repair, such as excessive melt by the melt heater flows down or the thickness of the repair pad is thinner, such as poor durability, Due to the embedded molten heater, the repair pad is formed to be thick, so that the manufacturing cost increases and the problem of causing the flow rate decrease in the pipe is solved.

즉, 본 고안은 융착보수패드에 있어서, 보수패드의 융착 접합면에 용융히터가 매설된 융착용융판을 분리 구비한 것이다.That is, in the fusion repair pad, the present invention is provided with a fusion molten plate in which a fusion heater is embedded in the fusion bonding surface of the repair pad.

따라서, 본 고안은 보수패드의 융착 접합면에 용융히터가 매설된 융착용융판을 분리 구비함으로써 용융히터에 의한 가열과정에 있어 융착 용융판이 우선 용융된 후 보수패드의 융착 접합면과 라이너의 보수면이 부분 용융되어 보수패드가 용융되어 흘러내리는 현상 또는 보수패드의 두께가 얇아지는 현상이 방지되어 보수패드의 내구성과 시공성이 향상되는 것이다.Therefore, the present invention is to separate the fusion molten plate in which the molten heater is embedded in the fusion bonding surface of the repair pad, the fusion molten plate is first melted in the heating process by the molten heater, and then the fusion bonding surface of the repair pad and the repair surface of the liner This partial melting prevents the phenomenon that the repair pad melts and flows down or the thickness of the repair pad becomes thin, thereby improving durability and workability of the repair pad.

상기 융착 용융판(20)은 도 3 에 도시된 바와 같이 외측테두리에 보수패드(10)의 상면에 결합된 상태를 유지하면서 융착 접합면(11)에 용융히터(30)가 직접 작용되지 않게 융착 접합면(11)과 융착 용융판(20) 사이에 분리층(12)이 형성되도록 외측테두리만이 결속되게 외측융착고정부(21)를 형성한 것이다.As shown in FIG. 3, the fusion plate 20 is fused so that the fusion heater 30 does not directly act on the fusion splicing surface 11 while maintaining the state of being bonded to the top surface of the repair pad 10 on the outer edge. The outer fusion fixing part 21 is formed so that only the outer edge is bound so that the separation layer 12 is formed between the joining surface 11 and the fusion molten plate 20.

상기 융착 용융판(20)의 보수패드(10)의 융착 접합면(11)과의 결합 견고성을 높일 수 있게 중앙부분을 도넛 형상으로 부분 절개하고 절개 형성되 내측테두리에 보수패드의 융착 접합면(11)에 융착 결속된 내측융착고정부(22)를 형성하여 실시할 수 있는 것이다.The fusion bonding surface 11 of the repair pad is formed on the inner edge by partially cutting and cutting the center portion into a donut shape so as to increase the bonding firmness with the fusion bonding surface 11 of the repair pad 10 of the fusion molten plate 20. It can be carried out by forming the inner fusion fixing part 22 fused to the fusion).

한편, 상기 보수패드(10)와 융착 용융판(20)은 보수관(110)의 특성한 곡면으 로 이루는 보수면(111)에 대응할 수 있게 호형으로 형성하여 실시함이 바람직한 것이다.On the other hand, the repair pad 10 and the fusion molten plate 20 is preferably formed in an arc shape so as to correspond to the repair surface 111 consisting of the characteristic curved surface of the repair pipe 110.

이하, 본 고안의 사용과정에 대하여 설명하면 다음과 같다.Hereinafter, the use process of the present invention will be described.
