Description

이음새 고정부재를 이용한 저수조의 라이닝 방법{Reservoir Lining Method}Lining method of reservoir using joint fixing member{Reservoir Lining Method}

본 발명은 배수지, 침전지, 여과지를 포함하는 상수도 시설 등에 사용되는 저수조의 라이닝 방법에 관한 것이다.The present invention relates to a lining method of a water storage tank used in a water supply facility including a drainage basin, a settling basin, and a filter paper.

배수지, 침전지, 여과지를 포함하는 상수도 시설 등에 사용되는 저수조는 콘크리트구조물로 형성되는 것이 일반적이다.Reservoirs used in water supply facilities, including drainage basins, sedimentation basins, and filter basins, are generally formed of concrete structures.

이러한 콘크리트구조물로 이루어진 저수조는 콘크리트 등에 포함된 유해물질이 물에 녹아들게 되고, 이물이 얼고 녹음의 반복에 따라 쉽게 균열이 발생하게 되어 지속적인 누수와 세균 침투 등의 문제점이 발생하는 등 음용수로서 부적합한 측면이 있다.The water tank made of such a concrete structure is unsuitable as drinking water, such as harmful substances contained in concrete are dissolved in water, foreign substances freeze and cracks easily occur according to repeated greening, resulting in problems such as continuous leakage and penetration of bacteria. There is this.

따라서 콘크리트구조물로 이루어진 저수조는 통상 방수 라이닝(Lining) 작업을 하고 있다.Therefore, a water tank made of a concrete structure is usually waterproof lining.

여기서 종래에 게시된 저수조의 방수 라이닝 관련기술 중 대표적인 기술은 등록특허 제10-0927316호가 있으며, 상기 등록특허 제10-0927316호는 저수조 방수공법에 있어서; 상단표면에 접착제층을 구비하는 다수개의 고정구를 저수조 내벽에 설치하고, 고정구의 상단표면에 배면이 접촉되도록 항균성 방수시트를 위치시키며, 항균성 방수시트의 정면에서 유도가열(誘導加熱)에 의한 고주파를 고정구에 조사하여 항균성 방수시트를 고정구에 고주파 융착하되, 상기 항균성 방수시트는 선형저밀도 폴리에틸렌 35∼50wt%, 에틸렌 비닐아세테이트50∼65wt%로 이루어진 베이스층을 중심으로 상하부면에 은계 항균필름이 라미네이트된 것을 특징으로 한다.Here, a representative technology among the technologies related to the waterproof lining of the water storage tank that has been published in the related art is Registration Patent No. 10-0927316, and the Registration Patent No. 10-0927316 is used in the water tank waterproofing method; A plurality of fixtures with an adhesive layer on the top surface are installed on the inner wall of the reservoir, and an antibacterial waterproof sheet is placed so that the back surface of the fixture is in contact, and high frequency by induction heating is applied in front of the antibacterial waterproof sheet. The antimicrobial waterproof sheet is high-frequency fused to the fixture by irradiating the fixture, but the antibacterial waterproof sheet has a silver-based antibacterial film laminated on the upper and lower surfaces around a base layer made of linear low density polyethylene 35-50wt% and ethylene vinyl acetate 50-65wt%. It is characterized by that.

상기 등록특허 제10-0927316호는 고정구를 이용한 고주파 유도가열에 의해 항균성 방수시트를 부착시공하여 방수층 시공시간을 단축시키는 효과는 있지만, 고주파융착에 의해 고정구에 접착된 접착제와 방수시트가 접착되나, 접착제와 방수시트는 이종 재질로 동일재질의 융착에 의한 접착강도보다 접착력이 떨어질 뿐만 아니라 방수시트와 고정구가 정확하게 고정되지 않고 편심되게 유도가열될 경우, 허공에 가열하는 경우가 많아 배면 융착성능을 보증할 수 없는 문제점과 물의 수위변화에 따라 수축과 팽창이 반복되면서 고정구에서 방수시트가 떨어져 유동하므로 누수가 발생하는 문제점이 있었다.The above Patent No. 10-0927316 has the effect of shortening the construction time of the waterproof layer by attaching an antimicrobial waterproof sheet by high-frequency induction heating using a fixture, but the adhesive and the waterproof sheet adhered to the fixture by high-frequency fusion, The adhesive and waterproof sheet are different materials, and the adhesive strength is lower than the adhesive strength by fusion of the same material, and when the waterproof sheet and fixture are not accurately fixed and eccentrically heated, they are often heated in the air, thus guaranteeing the rear fusion performance. There is a problem that water leakage occurs because the waterproof sheet falls off and flows from the fixture as the contraction and expansion are repeated according to the change of the water level and the water level cannot be changed.

도 2에 도시된 바와 같이 제5단계는 상기 제4단계가 완료된 밀폐판(20) 사이에, 폴리에틸렌판인 마감시트(30)를 안착시켜 열풍 융착기를 이용하여 융착하거나, 폴리우레아 100중량부를 기준으로 경화제 30 ~ 50중량부, 실란커플링제 10 ~ 30중량부, 불소발수제 5 ~ 15중량부가 혼합되어 이루어지는 마감층(40)을 도포하여 경화시키는 것을 포함한다.As shown in FIG. 2, the fifth step is based on 100 parts by weight of polyurea by placing the finishing sheet 30, which is a polyethylene plate, between the sealing plates 20 where the fourth step has been completed, and using a hot air splicer. As a curing agent 30 to 50 parts by weight, 10 to 30 parts by weight of a silane coupling agent, and 5 to 15 parts by weight of a fluorine water-repellent agent is mixed to include coating and curing the finishing layer 40.

즉, 마감시트(30)가 다수의 밀폐판(20) 사이를 밀폐하여 주어 밀폐력을 더욱 향상시키는 것은 물론 마감시트(30)가 열풍 융착기를 이용하여 다수의 밀폐판(20) 사이에 융착되어 보강판(10)과 밀폐판(20)이 융착될 때 같이 작업이 이루어져 작업이 편리하게 이루어지게 된다.That is, the finishing sheet 30 seals between a plurality of sealing plates 20 to further improve the sealing power, as well as the finishing sheet 30 is fused between a plurality of sealing plates 20 using a hot air fusion machine to reinforce When the plate 10 and the sealing plate 20 are fused together, the same operation is performed so that the operation is conveniently performed.

또한, 마감시트(30)와 함께 마감층(40)을 도포하여 다수의 밀폐판(20) 사이를 밀폐할 수 있으며, 여기서 마감층(40)은 폴리우레아 100중량부를 기준으로 경화제 30 ~ 50중량부, 실란커플링제 10 ~ 30중량부, 불소발수제 5 ~ 15중량부가 혼합되어 이루어진다.In addition, it is possible to seal between a plurality of sealing plates 20 by applying the finishing layer 40 together with the finishing sheet 30, where the finishing layer 40 is 30 to 50 parts by weight of a curing agent based on 100 parts by weight of polyurea. Parts, 10 to 30 parts by weight of a silane coupling agent, and 5 to 15 parts by weight of a fluorine water repellent are mixed.

폴리우레아는 아이소사이아네이트 구성요소와 합성수지 혼합 구성요소의 반응 산물로부터 유도된 탄성 중합체로서, 밀폐판(20) 사이에 도포됨과 동시에 순간적으로 완전히 접착되면서 대단히 높은 강도를 지녀 밀폐판(20) 사이의 밀폐력을 향상시키게 된다.Polyurea is an elastomer derived from the reaction product of an isocyanate component and a synthetic resin mixture component. It is applied between the sealing plates 20 and at the same time is instantly completely bonded and has a very high strength. It will improve the sealing power of the.

또한, 폴리우레아는 냄새가 없고, 휘발성 유기화합물(VOC)의 배출이 없어 환경에도 안전하고 작업자들의 작업환경을 개선하게 되며, 방수성이 뛰어난 탄력적이고 매끄러운 층을 형성하여 작업이 미려하게 이루어질 수 있다.In addition, polyurea has no odor and does not emit volatile organic compounds (VOC), so it is safe in the environment and improves the working environment of workers, and it forms a resilient and smooth layer with excellent waterproof properties, so that the work can be performed beautifully.

경화제는 폴리우레아 100중량부를 기준으로, 30 ~ 50중량부가 혼합되면서 적절한 경화작용으로 인해 밀폐판(20) 사이에 스프레이 방식으로 마감층(40)이 도포되어도 흘러내리지 않고 특히 수직면에서도 흘러내림 없이 도포작업을 실시할 수 있어 시공이 편리하게 이루어지는 것은 물론 원하는 두께로 시공이 가능하다.The curing agent does not flow down even if the finishing layer 40 is applied between the sealing plates 20 by spraying due to the proper curing effect while 30 to 50 parts by weight of the curing agent is mixed based on 100 parts by weight of polyurea, and is applied without dripping, especially on a vertical surface. Since the work can be carried out, the construction is not only convenient, but also the desired thickness is possible.

실란커플링제는 마감층(40)의 접착력 및 점성을 유지시켜 주게 되어 밀폐판(20) 사이를 접착하는 기능을 구비할 수 있도록 한다.The silane coupling agent maintains the adhesion and viscosity of the finishing layer 40 so that it can have a function of bonding between the sealing plates 20.

불소발수제는 마감층(40)의 발수성능을 부여하여 저수조 내의 물이 밀폐판(20) 사이에 스며드는 것을 방지하도록 한다.The fluorine water repellent imparts water repellency of the finishing layer 40 to prevent water in the water storage tank from permeating between the sealing plates 20.

즉, 마감시트(30)와 마감층(40)을 적절히 혼용하여 사용함으로써, 밀폐판(20) 사이를 밀폐하여 저수조 내부의 밀폐력을 더욱 향상시키면서도 작업조건에 맞게 선택적으로 마감시트(30)와 마감층(40)을 시공하여 작업이 편리해지는 효과가 있게 되는 것이다.That is, by appropriately mixing the finishing sheet 30 and the finishing layer 40, the sealing plate 20 is sealed between the sealing plates 20 to further improve the sealing power inside the reservoir, while selectively finishing the finishing sheet 30 and finishing according to the working conditions. By constructing the layer 40, there is an effect that the operation becomes convenient.

또한, 제5단계는 밀폐판(20) 사이를 보다 견고하게 밀폐하기 위하여 도 3에 도시된 바와 같이 상기 제4단계가 완료된 밀폐판(20) 사이에, 폴리에틸렌판인 마감시트(30)를 안착시켜 열풍 융착기를 이용하여 융착한 후, 폴리우레아 100중량부를 기준으로 경화제 30 ~ 50중량부, 실란커플링제 10 ~ 30중량부, 불소발수제 5 ~ 15중량부가 혼합되어 이루어지는 마감층(40)을 마감시트(30)를 덮도록 도포하여 경화시키도록 구성된다.In addition, in the fifth step, a finishing sheet 30, which is a polyethylene plate, is seated between the sealing plates 20 in which the fourth step is completed, as shown in FIG. 3 in order to seal the sealing plates 20 more firmly. After fusion using a hot air splicer, finish the finishing layer 40 formed by mixing 30 to 50 parts by weight of a curing agent, 10 to 30 parts by weight of a silane coupling agent, and 5 to 15 parts by weight of a fluorine water repellent based on 100 parts by weight of polyurea. It is configured to cure by applying it so as to cover the sheet 30.

즉, 마감시트(30)와 마감층(40) 이중으로 밀폐판(20) 사이를 밀페함으로써 완벽하게 밀폐구조를 구현하는 효과를 발휘하게 된다.In other words, by sealing between the sealing plate 20 in the double of the finishing sheet 30 and the finishing layer 40, the effect of implementing a completely sealed structure is exhibited.
