Description
본 발명은 교면방수제 조성물 및 이를 이용한 방수공법에 관한 것으로서, 보다 상세하게는 콘크리트 구조물, 포장면 등의 교면에 방수포장면을 형성시켜 내구성, 방수성, 염화물 침투 저항성을 향상시킬 수 있는 교면방수제 조성물 및 이를 이용한 방수공법에 관한 것이다.The present invention relates to a bridge surface waterproofing composition and a waterproofing method using the same, and more particularly, a bridge surface waterproofing composition capable of improving durability, waterproofness, and chloride penetration resistance by forming a waterproofing surface on bridge surfaces such as concrete structures and pavements, and the same It is about the waterproof method used.
일반적으로, 콘크리트 교량 또는 구조물의 교면은 공용 연수가 증가할수록 빗물이나 제설재의 침투량이 많아지고 교면에 가해지는 하중이 누적되므로 재료 간 결합력이 저하되고 온도변화에 따른 물의 체적변화 등으로 균열이 발생하기 쉽다.In general, in the bridge surface of a concrete bridge or structure, as the number of years of use increases, the penetration of rainwater or snow removal material increases and the load applied to the bridge surface accumulates, so the bonding force between materials decreases and cracks occur due to changes in the volume of water due to temperature changes. easy.
콘크리트 구조물 등의 균열은 시간이 경과할수록 확대되어, 콘크리트 구조물의 강도 및 수명 저하를 초래하고, 우수 등이 아스팔트 공극 균열부분과 중앙분리대 및 조인트 부위의 틈새를 통해 침투 시, 콘크리트 내부의 철근이 부식되어 구조물의 수명단축 및 붕괴를 초래한다.Cracks in concrete structures, etc., increase over time, leading to a decrease in the strength and life of the concrete structure, and when rain penetrates through cracks in asphalt voids and gaps in the central separator and joints, the reinforcement inside the concrete is corroded. It will shorten the life of the structure and cause collapse.
따라서 빗물이나 제설재 등이 침투되어 콘크리트 구조물의 강도 및 수명이 저하되는 것을 방지하기 위하여 콘크리트 교량 또는 구조물의 교면에 방수제를 도포하고 있다. 이러한 콘크리트 구조물의 교면에 방수제를 도포함으로써, 포장층으로부터 침투되는 물과 염화물에 의한 바닥판 콘크리트의 열화 및 철근 부식을 방지할 수 있다.Therefore, a waterproofing agent is applied to a concrete bridge or a bridge surface of a structure to prevent the strength and lifespan of the concrete structure from deteriorating due to penetration of rainwater or snow removal material. By applying a waterproofing agent to the bridge surface of such a concrete structure, it is possible to prevent deterioration of the deck concrete and corrosion of reinforcing bars due to water and chlorides penetrating from the pavement layer.
콘크리트 교면 방수제는 건축 및 기타분야에 적용되는 방수재와 달리 주행차량에 의한 반복하중, 진동, 충격, 전단 등의 역학적 작용과 온도변화에 의한 수축ㅇ팽창 등이 복잡하게 작용하는 교면에 사용되므로 교면 방수제층은 손상되기 쉽고, 이로 인해 손상된 교면 방수제층을 보수하거나 보강하는 데는 많은 비용이 소요될 뿐만 아니라 공사 중 차로를 부분 통제함으로써 교통지체를 유발하는 문제점이 있다.Concrete bridge waterproofing agent, unlike waterproofing materials applied to construction and other fields, is used for bridge surfaces where mechanical effects such as cyclic load, vibration, shock, shear, etc. by running vehicles and contraction or expansion due to temperature change are complex. The floor is apt to be damaged, and due to this, it takes a lot of cost to repair or reinforce the damaged bridge waterproofing layer, and there is a problem of causing traffic delay by partially controlling lanes during construction.
한편, 콘크리트 교면에 적용되는 방수공법으로는, 침투식 방수공법, 시트식 방수공법 및 도막식 방수공법이 있다. 침투식 방수공법은 적용하기에 매우 간편하고 경제적인 이유로 폭넓게 사용되어 왔으나 고강도 콘크리트 교면에는 방수제가 충분히 침투되지 않아 방수성능을 기대할 수 없는 단점이 있으며, 시트식 방수공법은 저온특성이 떨어져 우리나라와 같이 사계절이 있는 나라의 경우 콘크리트 교면의 방수성능 향상에 큰 효과를 나타내지 못하는 문제점이 있다. On the other hand, as a waterproofing method applied to a concrete bridge, there are a penetration type waterproofing method, a sheet type waterproofing method, and a coating type waterproofing method. The penetration-type waterproofing method is very simple to apply and has been widely used for economic reasons, but there is a disadvantage that waterproofing performance cannot be expected because the waterproofing agent does not sufficiently penetrate into the high-strength concrete bridge surface. In the case of a country with four seasons, there is a problem that it does not show a great effect in improving the waterproof performance of the concrete bridge surface.
따라서 최근에는 합성수지재료를 도포해서 방수도막을 형성시켜 시공하는 도막식방수공법이 선호되고 있다.Therefore, in recent years, a coating-type waterproofing method in which a synthetic resin material is applied to form a waterproof coating for construction is preferred.
도막식 방수공법을 적용한 예를 살펴보면, 대한민국 공개특허 제 1999-37809호에는, 교량 등의 표면에 에폭시 프라이머 층을 도포하고 그 위에 속건성 고분자 수지층과 지건성 고분자 수지층 및 세석골재층을 형성하는 교면 방수공법이 개시되어 있다.Looking at an example of applying the coating-type waterproofing method, in Korean Patent Laid-Open No. 1999-37809, an epoxy primer layer is applied to the surface of a bridge, etc., and a quick-drying polymer resin layer, an oil-drying polymer resin layer, and a fine stone aggregate layer are formed thereon. The bridge surface waterproofing method is disclosed.
하지만, 상기 공개특허에 개시된 교면 방수공법에 적용된 고분자 수지층은 5초 이내에 경화되는 속건성 이어서 아스팔트 콘크리트와 아스팔트 및 에폭시 프라이머 층이 상호 융합되기도 전에 각 층이 분리되거나 크랙이 발생하는 바, 충분한 방수효과를 기대할 수 없다. 또한, 프라이머층 위에 속건성 및 지건성 고분자 수지 층과 세석골재층 등 다양한 처리층을 형성해야하는데, 이와 같이 다중층을 적층하지 않으면 각 층의 접착력이 약해져서 밀리게 되어 층분리 현상이 발생하게 되는바, 실제로 시공을 할 수 없거나 시공을 하더라도 방수효과가 떨어지는 문제점이 있다.However, the polymer resin layer applied to the bridge surface waterproofing method disclosed in the above patent is quick-drying that hardens within 5 seconds, so that each layer is separated or cracked before the asphalt concrete, asphalt, and epoxy primer layers are fused together. Can't expect In addition, various treatment layers, such as a quick-drying and oil-drying polymer resin layer and a fine stone aggregate layer, must be formed on the primer layer.If multiple layers are not stacked in this way, the adhesive strength of each layer is weakened and the layer separation phenomenon occurs. , There is a problem that the waterproofing effect is inferior even if it cannot be actually constructed or even if it is constructed.
이러한 다중층의 문제점을 보완하기 위하여 대한민국 공개특허 제 2002-76214호에서는 교량 등의 표면에 폴리우레탄수지 프라이머층을 도포한 후 그 위에 속건성 고분자 수지층을 형성하고, 그위에 과량의 이소시아네이트를 첨가한 폴리우레탄 제조 혼합물을 도포한 후 아스팔트 접착제층과 아스팔트 콘크리트층을 차례로 적층하는 처리방법을 개시하고 있다. In order to compensate for this multi-layer problem, Korean Patent Laid-Open No. 2002-76214 applies a polyurethane resin primer layer to the surface of a bridge, etc., and then forms a quick-drying polymer resin layer thereon, and an excess of isocyanate is added thereon. Disclosed is a treatment method of sequentially laminating an asphalt adhesive layer and an asphalt concrete layer after applying a polyurethane preparation mixture.
그러나 이 방법은 폴리우레탄 제조 혼합물층에 존재하는 과량의 이소시아네이트가 주위의 습기와 반응하여 오히려 결합력이 약해지는 단점이 있으며, 이러한 문제점을 방지하기 위해 현장에서 작업시 매우 주의를 요하는 까다로운 작업공정을 필요로 하게 되는 또 다른 문제점이 발생한다.However, this method has the disadvantage that the bonding strength is weakened because the excess isocyanate present in the polyurethane production mixture layer reacts with the surrounding moisture, and in order to prevent this problem, a tricky work process that requires very attention when working in the field is required. Another problem arises that becomes necessary.
본 발명은 상기와 같은 문제점을 해결하기 위해 창출한 것으로, 콘크리트 구조물의 미세균열 및 모세관 공극 등의 침투성능이 우수하여 내투수 저항성이 탁월하고, 외부하중이나 충격 등으로 손상받기 쉬운 콘크리트 교면과 방수제 계면의 결합을 공고히 함으로써 콘크리트 교면의 내구성을 대폭 향상시킬 수 있도록 하는 교면방수제 조성물을 제공하고자 한다.The present invention was created to solve the above problems, and has excellent permeability resistance due to excellent penetration performance such as microcracks and capillary voids of concrete structures, and concrete bridge surfaces and waterproofing agents that are easily damaged by external loads or impacts. It is intended to provide a bridge surface waterproofing composition that can significantly improve the durability of a concrete bridge surface by strengthening the bonding of the interface.

본 발명에 따른 아스팔트는 당업계에서 통상적으로 사용되는 아스팔트라면 특별히 한정되지 않지만, 추천하기로는 석유계 아스팔트 또는 아스팔트 혼합물을 사용할 수 있다.The asphalt according to the present invention is not particularly limited as long as it is an asphalt commonly used in the art, but petroleum-based asphalt or an asphalt mixture may be recommended.
여기서, 상기 아스팔트 혼합물은 천연 아스팔트 혼합물을 사용하는 것을 추천한다.Here, it is recommended to use a natural asphalt mixture as the asphalt mixture.
상기 아스팔트 혼합물, 특정적으로 천연 아스팔트 혼합물은 당업계에서 통상적으로 사용되는 천연 아스팔트 혼합물이라면 특별히 한정되지 않지만, 바람직하게는 스트레이트(straight) 아스팔트, 트리니다드레이크(Trinidad lake) 아스팔트, 트리니다드에퓨레(Trinidad epure) 아스팔트 또는 이들로부터 선택된 적어도 하나 이상의 혼합물을 사용하는 것이 좋고, 보다 바람직하게는 침입도 20 내지 40의 스트레이트 아스팔트와 천연 아스팔트, 예를 들면 트리니다드레이크 아스팔트 및/또는 트리니다드에퓨레 아스팔트 혼합물을 사용하는 것이 좋고, 더욱 바람직하게는 침입도 20 내지 40의 스트레이트 아스팔트 70 내지 80중량% 및 트리니다드레이크 아스팔트 또는 트리니다드에퓨레 아스팔트로 이루어진 천연 아스팔트 20 내지 30중량%를 혼합한 것을 사용하는 것을 추천한다.The asphalt mixture, in particular, the natural asphalt mixture is not particularly limited as long as it is a natural asphalt mixture commonly used in the art, but preferably straight asphalt, Trinidad lake asphalt, Trinidad epure (Trinidad epure) ) It is preferable to use asphalt or a mixture of at least one or more selected from these, more preferably a mixture of straight asphalt and natural asphalt with a penetration degree of 20 to 40, for example Trinidadrake asphalt and/or Trinidad ePure asphalt.
