Description
본 발명은 콘크리트관, 하수처리장의 탱크 등의 콘크리트구조물의 내부에 내부식성이 강한 시트(sheet)를 결합시켜 콘크리트 구조물의 부식 또는 산업 폐수 등에 의한 화학적 반응 등에 대해 구조물을 적절하게 보호 할수 있고 또한 방수의 기능이 향상되는 콘크리트구조물의 보수보강공법 및 이에 의해 제조된 콘크리트구조물에 관한 것이다.The present invention combines a highly corrosion-resistant sheet in the interior of concrete structures such as concrete pipes, tanks of sewage treatment plants to properly protect the structure against chemical reactions such as corrosion of the concrete structure or industrial wastewater and also waterproof. The present invention relates to a repair and reinforcement method of a concrete structure, and a concrete structure manufactured thereby.
종래의 콘크리트관이나 하수처리장의 탱크 등은 자체의 강도 등을 증대하기 위해 철근 등을 내부에 포함하는 것이 일반적이다.Conventional concrete pipes and tanks of sewage treatment plants generally include reinforcing bars in order to increase their strength and the like.
또한, 하수처리장의 탱크 등은 탱크내에 수용된 처리수 등을 물리적 또는 화학적으로 약품 처리하기 위해 탱크 내부의 자체 강도를 유지하여야 함은 물론 화학적 처리에 의해 발생되는 부식에 견디는 내부식성을 가져야 한다.In addition, the tank of the sewage treatment plant should maintain its own strength inside the tank in order to chemically treat the treated water contained in the tank or the like, as well as have corrosion resistance against corrosion caused by chemical treatment.
그러나, 통상의 콘크리트관이나 콘크리트로 제조된 콘크리트탱크는 내부식성이 떨어지는 문제점이 있었다. However, conventional concrete pipes or concrete tanks made of concrete had a problem of poor corrosion resistance.
따라서, 콘크리트관이나 콘크리트구조물의 보수기간이 단축됨은 물론 내구성이 저하되는 문제점이 발생되었다.Therefore, the maintenance period of the concrete tube or concrete structure is shortened, as well as a problem that the durability is lowered.
본 발명은 상기의 이와 같은 문제점을 해소시키기 위해 안출된 것으로서, 본 발명의 목적은 콘크리트관이나 콘크리트로 이루어진 콘크리트구조물의 보수보강이 간편하게 이루어지는 공법을 제공하고자 하는 것이다.The present invention has been made to solve the above problems, it is an object of the present invention to provide a construction method that is easy to repair and reinforcement of concrete structures made of concrete pipes or concrete.
본 발명의 다른 목적은 상기와 같은 공법에 의해 제조된 콘크리트관이나 콘크리트구조물을 제공하고자 하는 것이다.Another object of the present invention is to provide a concrete tube or concrete structure manufactured by the above method.
본 발명의 이와 같은 목적은 소정 형태의 콘크리트관이나 콘크리트구조물의 내부에 내부식성이 강한 시트재를 결합시키고, 콘크리트관과 시트재 사이의 양측면에 실링재로 밀폐시키고, 콘크리트관과 시트재 사이의 간극에 몰타르를 주입시킴으로써 달성된다.This object of the present invention is to bond a strong corrosion-resistant sheet material to the interior of the concrete pipe or concrete structure of a certain type, sealing the sealing material on both sides between the concrete pipe and the sheet material, the gap between the concrete pipe and the sheet material It is achieved by injecting mortar into it.
본 발명의 콘크리트 구조물의 보수 보강공법은 콘크리트 구조물의 백화현상, 부식 또는 산업 폐수 등 화학적 반응 등에 대해 구조물을 적절하게 보호할 수 있음은 물론 방수기능이 부가되는 것이 특징이다.Repair reinforcement method of the concrete structure of the present invention is capable of adequately protecting the structure against chemical reactions such as the phenomena of the concrete structure, corrosion or industrial wastewater, as well as the waterproof feature.
본 발명의 콘크리트 구조물의 보수 보강공법은 Repair reinforcement method of the concrete structure of the present invention
구조물에 알맞게 시트(sheet)를 내부에 결합시키는 단계, Bonding the sheet therein to suit the structure,
구조물의 내부와 시트사이의 공간 양측면을 밀봉시키는 단계,Sealing both sides of the space between the interior of the structure and the seat,
밀봉된 구조물의 내부와 시트 사이의 공간 내부로 몰타르를 주입하는 단계, Injecting mortar into the interior of the sealed structure and into the space between the sheet,
소정 기간의 경과후 주입된 몰타르의 경화에 의해 구조물과 시트가 완전히 결합되는 단계로 구성된 것이 특징이다.It is characterized in that the structure and the sheet is completely bonded by the curing of the injected mortar after a predetermined period of time.
본 발명의 콘크리트 구조물의 보수 보강공법은 콘크리트구조물의 보수시에 적용될 수 있다. 즉, 콘크리트구조물의 보수시에는 보수될 구조물의 내부를 세정하는 단계가 선행되어야 한다.Repair reinforcement method of the concrete structure of the present invention can be applied at the time of repair of the concrete structure. That is, when repairing the concrete structure, the step of cleaning the interior of the structure to be repaired must be preceded.
여기에서 시트는 고밀도폴리에틸렌(High Density Polyethylene)으로 구성되는 것이 바람직하다.Here, the sheet is preferably composed of High Density Polyethylene.
고밀도 폴리에틸렌재질의 시트는 일측면에 소정 높이의 돌기가 형성되어 배치되어 있다. 따라서, 시트와 구조물의 내면 사이에 배치되는 돌기에 의해 시트는 구조물의 내면으로부터 소정 간격으로 이격되게 배치되므로 자연적으로 공간부가 형성된다.Sheets of high-density polyethylene material are formed with protrusions of a predetermined height formed on one side. Accordingly, the space is naturally formed because the sheet is disposed to be spaced apart from the inner surface of the structure at predetermined intervals by projections disposed between the sheet and the inner surface of the structure.
이 공간부는 시트를 구조물과 완전히 결합고정되게 하기 위해 몰타르와 같은 중진제로 채워진 후 경화되어 고정된다.This space is filled with a neutralizing agent, such as mortar, and then hardened and fixed to completely secure the sheet to the structure.
충진재를 채우기 위해 공간부의 양측면은 실링재로 밀봉된다. 그리고, 밀봉된 공간부 내부로 몰타르와 같은 충진재를 주입하기 위한 주입구가 형성된다.Both sides of the space are sealed with sealing material to fill the filler. Then, an injection hole for injecting a filler such as mortar into the sealed space is formed.
또한, 주입구를 통해 공간부로 주입되는 충진재가 완전히 공간부를 채우도록 공기 배출구가 형성된다.In addition, the air outlet is formed such that the filler injected into the space through the injection hole completely fills the space.
주입구는 콘크리트구조물의 하부에 형성하고, 배출구는 상부에 형성하는 것이 바람직하다.The inlet is preferably formed at the bottom of the concrete structure, the outlet is preferably formed at the top.
하부의 주입구를 통해 소정 압력으로 주입된 충진재는 공간부의 하부로부터 상부로 충진되며, 이 때 공간부 상방의 배출구를 통해 공간부에 존재하는 공기가 배출된다.The filler injected at a predetermined pressure through the lower injection hole is filled from the lower part of the space part to the upper part, and at this time, air existing in the space part is discharged through the discharge port above the space part.
공간부가 완전히 충진된 후 소정의 시간이 경과되면 충진된 몰타르는 자연적으로 경화되고, 이에 의해 시트와 콘크리트구조물의 상호 완전히 결합된다.After a certain period of time after the space is completely filled, the filled mortar hardens naturally, thereby completely bonding the sheets and the concrete structure together.
본 발명의 이와 같은 공법은 터널과 같은 반원형 또는 박스형태의 사각형 콘크리트구조물에 적용 가능하다.This method of the present invention is applicable to semi-circular or box-shaped rectangular concrete structures such as tunnels.
그리고, 이와 같이 내구성 및 내부식성이 향상된 콘크리트구조물의 연결부분은 소정 폭의 시트를 전기융착방식으로 융착고정할 수 있다.In addition, the connection portion of the concrete structure with improved durability and corrosion resistance can be fusion-fixed sheet of a predetermined width by the electrofusion method.
이와 같은 방법으로 제조된 본 발명의 콘크리트구조물의 보수 보강공법 및 이에 의해 제조된 콘크리트관이나 콘크리트구조물은 콘크리트 구조물의 부식 또는 산업폐수 등에 의한 화학적 반응에 견디는 내부식성이 향상되고, 방수기능이 또한 향상되므로 구조물의 내구성이 향상되고, 구조물의 빈번하 보수가 방지되는 효과를 갖는다.Repair and reinforcement method of the concrete structure of the present invention manufactured by the above method and the concrete pipe or concrete structure produced thereby improves the corrosion resistance to withstand chemical reactions due to corrosion or industrial wastewater of the concrete structure, and also improves the waterproof function Therefore, the durability of the structure is improved, and the frequent maintenance of the structure is prevented.
