Description

철근콘크리트의 압력주입 방수방법Waterproofing method of pressure injection of reinforced concrete

본 발명은 철근콘크리트의 압력주입 방수방법에 관한 것으로서, 더욱 상세하게는 본 발명은 완성된 철근 콘크리트 구조물에서 누수가 되는 것을 방지하거나 하자보수를 하는 데 있어서 기존 구조물에 손상을 주지 않으면서 철저하고 완벽한 방수작업을 수행하는 철근콘크리트의 압력주입 방수방법에 관한 것이다.The present invention relates to a pressure injection waterproofing method of reinforced concrete, and more particularly, the present invention is a thorough and perfect without damaging the existing structure in preventing leakage or repairing the leak in the finished reinforced concrete structure The present invention relates to a pressure injection waterproofing method of reinforced concrete that performs waterproofing.

일반적으로 건축구조물을 설계의 목적대로 완공하고 어느 정도의 시일이 경과하면 어느정도의 하자보수작업이 불가피하게 되며 하자보수작업의 80% 이상이 누수에 관한 것이다. 건축물의 누수원인은 철근과 콘크리트와의 상호부작용에 의한 것으로서, 건축구조물의 모든 철근은 외부의 온도와 습도의 영향을 받아 수축 또는 팽창한다.In general, when a building structure is completed for the purpose of design and after a certain period of time, a certain amount of defect repair work is inevitable, and more than 80% of the repair work is related to leakage. The leakage of the building is caused by the interaction between the reinforcing bar and the concrete, and all the reinforcing bars in the building structure contract or expand under the influence of the external temperature and humidity.

다시 말하면, 철근의 형태상 수평철근과 수직철근으로 분류하는 데 이 중에서 수평철근은 그 자체가 압력을 지탱하고 있기 때문에 콘크리트 타설후에도 콘크리트의 침하현상으로 수평철근의 밑부분은 공극이 발생하게 되고, 이러한 상태에서 수분이 철근과 접촉하게 되면 모세관 현상으로 인해 철근을 산화 또는 부식시키며 누수가 발생한다.In other words, the horizontal reinforcing bars and vertical reinforcing bars are classified as horizontal reinforcing bars. Among them, the horizontal reinforcing bars themselves support pressure, so that even after the concrete is placed, the bottom of the horizontal reinforcing bars is caused by concrete subsidence. In this state, when water comes into contact with rebar, capillary phenomenon oxidizes or corrodes the rebar, causing water leakage.

이와 같은 문제점을 해결하기 위하여 다양한 방수방법이 적용되고 있다. 현재 국내에서 적용되는 방수방법으로는 도막방수방법과 보수방수방법, 유도방수방법, 미장방수방법, 시트방수방법, Injection 방수방법, Grout 방수방법 등이 있다.In order to solve this problem, various waterproof methods have been applied. Current waterproofing methods include waterproofing coating, waterproofing, induction waterproofing, plastering waterproofing, sheet waterproofing, injection waterproofing, and Grout waterproofing.

도막방수방법은 방수액을 표면에 칠하거나 품어서 막는 방법으로 페인트 종류, 모르타르, 우레탄, 실리콘, 에폭시 등 침투방수제품을 사용하고, 보수방수방법은 누수부위를 깊게 파내어 누수지점 전체를 방수액으로 막아 보수하여 방수하는 방법을 말하는 것이며, 유도방수방법은 파이프에 물이 스며들도록 구멍을 여러 형태로 뚫어놓고 누수지역을 기점으로 벽체에 홈을 파서 파이프에 묻음으로써 물줄기를 돌려놓는 방수방법이고, 미장방수방법은 시멘트에 방수액을 첨가하여 흙손이나 손으로 누수표면 전체를 덧씌우는 방수방법이고, 시트방수방법은 방수가 되는 비닐계통이나 벤토나이트, 아스팔트 등을 두루마리 처리하여 표면에 부착 또는 밀착시시키는 방수방법이다. 그리고 Injection 방수방법은 화공약품인 우레탄, 에폭시 등의 화학적 성질을 응용하여 공극을 채우는 주사방법이며, Grout 방수방법은 주입하려는 곳을 천공하여 시멘트 방수 모르타르를 주입하는 방수방법이다.The waterproofing method of coating film is to paint or incubate the waterproofing liquid on the surface and use infiltration waterproofing products such as paint, mortar, urethane, silicone, epoxy, etc., and the waterproofing method is to dig deeply the leaking area and close the leaking point with the waterproofing solution. It refers to a method of waterproofing by induction, and the induction waterproofing method is a waterproofing method in which a body of water is returned by drilling holes in various forms so that water penetrates into a pipe, digging a groove in a wall and burying it in a pipe. It is a waterproof method that covers the entire leaking surface with a trowel or hand by adding a waterproofing solution to silver cement, and the sheet waterproofing method is a waterproof method that attaches or adheres to the surface by treating the waterproof vinyl system, bentonite, asphalt, etc. And Injection waterproof method is injection method to fill voids by applying chemical properties such as urethane and epoxy chemicals, and Grout waterproof method is waterproof method to inject cement waterproof mortar by drilling the place to be injected.

그러나, 방수공사는 건축구조물 자체에 대한 파악 뿐만 아니라 주변환경 및 지하수와 토질을 염두에 두고 시공순서, 시공방법, 시공재료를 올바르게 적용시켜야 하는데 종래의 방수방법은 방수약품이나 재료에 주안점을 두기 때문에 공사기간과 인력, 공사비를 낭비하는 문제점이 있었다.However, waterproof construction should apply the construction order, construction method, and construction materials correctly in consideration of the surrounding environment, groundwater and soil, as well as understanding the construction structure itself. Since the conventional waterproofing method focuses on waterproof chemicals and materials, There was a problem of wasting construction period, manpower, and construction costs.

따라서, 본 발명은 상기의 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 건축물의 하자발생에서 누수하자를 원인과 과정, 그리고 결과에 대하여 올바르게 이해하고 그에 적절한 방수방법을 적용하며, 공사기간과 인력, 그리고 공사비의 불필요한 소모를 방지하고, 완벽한 방수공사가 이루어지도록 하는 철근콘크리트의 압력주입 방수방법을 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to correctly understand the causes, processes, and results of leaks in the occurrence of defects in buildings and to apply the appropriate waterproofing method to the construction period, It is to provide a pressure injection waterproofing method for reinforced concrete to prevent unnecessary consumption of labor, manpower, and construction cost, and to achieve perfect waterproof construction.

Indentation pipe installation process (S3) and through the indentation pipe to remove the cracks and fine fragments in the air gap of 1 ~ 2kg / ㎠ pressure, and then press the water in the cracks or voids Increase the pressure and the concentration of the cement paste by starting the cavities washing process (S4) for chucking and wetting and the cement paste mixed with micro cement of water of 8,000 cm2 / g or more powder in water at a low pressure of 1 kg / cm2 or less at the initial pressure. When the pressure rises without further filling at 10kg / cm 2, the cement paste indentation process (S5) is completed after checking the indentation filling of the cement paste, and the indentation pipe is deeply cut out and the cemented cement mortar The finishing process (S6) to finish to match the existing wall surface.

상기와 같이 구성된 본 발명에 의한 철근콘크리트의 압력주입 방수방법에 대해 도면을 참조하여 설명하면 다음과 같다.Referring to the drawings the pressure injection waterproofing method of the reinforced concrete according to the present invention configured as described above are as follows.

먼저 설계도면과 철근 콘크리트의 내·외부현황과 누수상태 등을 조사하여 구조물에 형성된 수맥을 찾아서 그 수맥을 중심으로 하여 천공위치를 선정하는 사전 조사공정(S1)을 수행한다.First, the design drawing and the internal and external status of the reinforced concrete and the leaked state are examined to find the veins formed in the structure, and the preliminary investigation process (S1) is performed to select the perforation locations centered on the veins.

이어서, 선정한 천공위치에 압입관을 설치하고 콘크리트의 내부균열, 공극 등에 시멘트의 압입이 용이하도록 역삼각형(내부로 들어갈수록 넓게 천공)으로 천공하는 천공공정(S2)을 수행한다.Subsequently, the press-fitting pipe is installed at the selected punching position, and the punching process (S2) is performed to invert the triangle (the wider the inside, the wider the punching) to facilitate the press-fitting of cement to the internal cracks and voids of the concrete.

다음에는 천공부에 압입관을 설치하고 천공부 안쪽깊이 2/3는 2~5mm의 굵은 모레를 채워서 압입관이 압입압력에 의해서 요동되지 않도록 하고, 바깥쪽깊이 1/3은 벽표면과 일치시켜 평활하게 급결시멘트 모르타르를 시공하여 압입관을 고정시키는 압입관 설치공정(S3)을 수행한다.Next, install a press-fit pipe in the perforation part and fill a 2 ~ 5mm thick more with 2/3 of the inner depth of the perforation part so that the press-fit pipe does not swing under the press-in pressure, and the outer depth 1/3 matches the wall surface. Perform the press fitting pipe installation process (S3) to fix the press fitting pipe by constructing the fastened cement mortar smoothly.

그 다음 압입관을 통하여 1~2kg/㎠ 압력의 공기로 균열이나 공극부내의 미세분진과 미세조각 등을 제거하여 시멘트페이스트의 압입이 용이하게 하고 다음으로 물을 압입하여 콘크리트 구조물을 습윤하게 하여 시멘트페이스트 압입시 균열부끝까지 시멘트페이스트의 압입이 용이하게 하는 공극부 세척공정(S4)을 수행한다. 즉, 콘크리트 구조물의 균열부 등이 건조하면 시멘트페이스트 압입시 수분을 구조물 자체가 흡수하므로 균열부나 공극 말단까지 침투가 안되고 중간에서 시멘트페이스트의 압입이 멈추게 된다.Then, through the press-in pipe, 1 ~ 2kg / ㎠ pressure air removes the cracks or fine dust and fine chips in the voids to facilitate the indentation of the cement paste, and then press-in water to wet the concrete structure. When the paste is press-fitted, a gap cleaning step (S4) is performed to facilitate the press-fitting of the cement paste to the crack end. That is, when the crack part of the concrete structure is dried, the structure itself absorbs moisture when the cement paste is press-fitted, so that the crack does not penetrate to the crack part or the pore end and the press-fit of the cement paste stops in the middle.

이어서 분말도 블레인 8,000㎠/g 이상의 마이크로 시멘트를 물에 섞은 시멘트페이스트를 초기압력 1kg/㎠ 이하의 저압에서 시작해서 압력과 시멘트페이스트의 농도를 서서히 증가시켜 10kg/㎠에서 시멘트페이스트 압입충진을 확인 후 종료하는 시멘트페이스트 압입공정(S5)을 수행한다.Then, start the cement paste mixed with micro cement of water of 8,000cm2 / g or more powder in water at low pressure below the initial pressure of 1kg / cm2 and gradually increase the pressure and the concentration of cement paste to confirm the cement paste indentation at 10kg / cm2. Cement paste indentation step (S5) to be performed.

그리고, 압입관을 깊게 잘라내고 초속경시멘트 모르타르로 기존 벽면과 일치되게 마무리하는 마감공정(S6)을 하여 본발명의 철근콘크리트의 압력주입 방수방법을 완료한다.Then, the press fitting pipe is deeply cut out and finished with a super fast cement mortar to match the existing wall surface (S6) to complete the pressure injection waterproofing method of the reinforced concrete of the present invention.

상술한 바와 같이, 본 발명에 의한 철근콘크리트의 압력주입 방수방법의 실시로 철근 콘크리내에 형성된 모든 균열 및 공극에 시멘트페이스트를 압입시켜 충진시킴으로써 콘크리트내에 존재하는 0.01mm 이하의 미세균열까지 제거하여 구조물 자체를 무공극화하여 완벽한 방수를 할 수 있는 효과가 있다. 또한 철근과 콘크리트 사이의 공극을 제거함으로써 구조물의 내구성도 향상시키며, 시공중 분진, 소음, 진동이 없고 구조물 자체의 훼손이 없으며 타공법에 비하여 시공비용도 절감할 수 있는 뛰어난 효과가 있다.As described above, by injecting and filling cement paste into all cracks and voids formed in the reinforced concrete by performing the pressure injection waterproofing method of reinforced concrete according to the present invention, the structure itself is removed by removing the microcracks of 0.01 mm or less present in the concrete. It is effective to make perfect waterproof by making no void. In addition, by removing the voids between the reinforcement and concrete, the durability of the structure is also improved, there is no dust, noise, vibration during construction, there is no damage of the structure itself, and there is an excellent effect of reducing the construction cost compared to other methods.
