본 발명은 부재를 이용한 수중콘크리트구조물의 보수/보강공법및 그부재 에 관한 것으로서, 특히 교량우물통, 항만파일등을 포함하는 수중콘크리트구조물들이 민물이나 해수에 의하여 손상을 입었을 때나 수중콘크리트구조물의 외주벽을 보강할때 손상된 부위 또는 수중콘크리트구조물의 주위에다 금속성 앵그부재 또는 GRThe present invention relates to a repair and reinforcement method of the underwater concrete structure using the member and its members, in particular when the underwater concrete structures including bridge wells, port piles, etc. are damaged by fresh water or seawater or the outer periphery of the underwater concrete structure Metal angle members or GR around damaged areas or underwater concrete structures when reinforcing walls

C(Glassfibre Reinforced Concrete)(플래스틱 또는 F.R.P)로 구성되는 GRC앵글부재와 GRC조성된 평판부재,곡판부재로 이루어지는 보수/보강부재를 덧뎀하고 이들 사이에 수중접착에폭시몰탈을 충전시켜 구조물손상부와 수중접착에폭시몰탈및 부재가 일체화로 되게 경화시키어 견고한 보수/보강구조물로 시공하므로서 영구적인 형태로 보존할 수 있도록 한 것이다.GRC angle member (Glassfibre Reinforced Concrete) (plastic or FRP), GRC flat plate member, and repair / reinforcement member consisting of curved plate member are overwritten and the epoxy resin mortar is filled between them to damage the structure and the water. The adhesive epoxy mortar and members are hardened to be integrated to be preserved in a permanent form by constructing a solid repair / reinforcement structure.

근래에 철근콘크리트의 토목구조물에 콘크리트가 박리/박락/비정상적인 크랙등 여러 가지의 열화현상으로 콘크리트의 압축강도와 철근의 인장강도가 떨어져서 철근콘크리트의 손상과 붕괴현상,철조구조물의 부식으로 인한 철조구조물의 파손등으로 인하여 야기되는 안전사고의 문제점이 큰 사회적 문제로 대두되고 있다,In recent years, concrete deteriorates such as peeling / falling / abnormal cracks in reinforced concrete civil structures. Compressive strength of concrete and tensile strength of reinforcing bars are reduced, resulting in damage and collapse of reinforced concrete and steel structures due to corrosion of steel structures. The problem of safety accidents caused by breakage of people has become a big social problem.

이러한, 콘크리트 열화인자/열화현상의 요인으로는 콘크리트가 강알칼리성As the deterioration factor / degradation factor of concrete, concrete is strongly alkaline

(PH=12.5)을 가지고 있어 철근 부식은 진행되지 않는다.(PH = 12.5), so corrosion of the rebar does not proceed.

그러나, 이러한 철근콘크리트 구조물에 탄산가스/산성물질/염물질(염소이However, carbon dioxide / acid / chlorine (chlorine dioxide)

온)의 침투와 알칼리골재반응과 기상조건하의 수축/팽창으로 인하여 철근콘크리트에 중성화 현상이 진행되고 철근이 부식이 진행되며 녹까지 쓸게 된다.Warming), alkali aggregate reaction and shrinkage / expansion under the weather conditions, the neutralization of reinforced concrete proceeds, the reinforcing steel is corroded and rust is used.

그리고, 철근에 녹이 슬게되면 녹의 팽창으로 인해 콘크리트조직에 균열이And, if the steel rusts, cracks in the concrete structure due to rust expansion

발생되고 철근콘크리트 구조물의 박리/박락/부식한 철근의 국부적인 노출현상등에 의하여 철근콘크리트가 파손되고 구조물이 붕괴에 이르게 되는 것이다.Reinforced concrete is damaged and the structure collapses due to the local exposure of reinforced concrete structures that are generated and peeled / falled / corroded.

또, 이러한 각종 토목 및 건축을 포함하는 시멘트콘크리트의 시설구조물들In addition, the facility structures of cement concrete including various civil and construction

이 탄산가스의 침투에 의해 중화되면서 콘크리트의 균열현상과 철근의 부식으로 시설구조물이 약화되는 현상은 탄산가스의 침투뿐 아니라, 시멘트콘크리트에 혼합되Neutralization by the infiltration of carbon dioxide gas causes the structure structure to be weakened due to the cracking of concrete and the corrosion of reinforcing steel.

는 자갈 및 모래가 화산암의 경우에는 시멘트콘크리트의 중성화현상이 가속되는 것으로 알려져 있다,In the case of gravel and sand is volcanic rock, it is known that the neutralization of cement concrete is accelerated.

상기와 같은 몰탈, 콘크리트등의 토목 건축물등 콘크리트구조물, 시멘트구Concrete structure such as mortar, concrete such as concrete structure, cement ball

조물의 열화 및 부식으로 손상된 손상부를 보수보강함에 있어, 일반적으로 토목 수중콘크리트구조물의 보수/보강시공을 할때 몰탈, 콘크리트로 에폭시수지로 보수보강 공사를 시공하고 있으나, 열화된 콘크리트 구조물의 보수보강 시공을 하여도 열화손상부와 보수/보강부재가 강도저하 및 일체화 되지 못하여 일정기간이 경과하면 보수/보강부가 이완되어 보수보강 기능이 상실되는 문제점이 많았다,In repairing and reinforcing damaged parts damaged due to deterioration and corrosion of the construction, in general, when repairing / reinforcing the civil concrete structures, reinforcing reinforcement of deteriorated concrete structures is carried out with mortar and concrete. Deterioration damaged part and repair / reinforcement member could not be reduced and integrated even after construction, and after a certain period of time, repair / reinforcement part was loosened and repair reinforcement function was lost.

특히, 교각 및 교각우물통과 항만구조물의 보수/보강시에는 수중손상부와 보수/보강재의 접착력이 미약하여 일체화되지 못하고 이완상태에서 경화 되므로 보수/보강재(부)가 박리/탈락되는 현상에 의해 보수/보강능력을 상실하게 되는 문제점이 많았다.In particular, when repairing / reinforcing bridges and bridge wells and port structures, the adhesive strength of underwater damage parts and repair / reinforcement materials is weak and cannot be integrated and hardens in a relaxed state. There were many problems that resulted in loss of reinforcement capacity.

더욱이 물이흐르는 교각의 경우에는 보수/보강재가 흐르는 유속에 의해 쉽게 유실되는 큰 문제점을 갖고 있으며, 철교등의 철물(금속)구조물의 보수/보강에서도 아크릴계, 우레탄계 등의 도료가 사용되고 있으나, 이러한 접착성이 우수한 수성도료는 방수기능은 있으나, 방청효과와 접착성이 양호하지 못하여 보수 피복층및 보강부(재)가 탈피되는 현상으로 보수/보강시공에 문제점이 있었다,Moreover, in the case of pier where water flows, it has a big problem that it is easily lost due to the flow rate of repair / reinforcement. In the repair / reinforcement of iron (metal) structures such as iron bridges, acrylic or urethane-based paints are used. The water-based paint has excellent water resistance, but it has a problem in repairing / reinforcing construction due to the phenomenon that the repair coating layer and the reinforcement part are peeled off due to poor rust prevention effect and adhesion.

또한, 종전의 열화된 콘크리트의 보수/보강 조성물 의 구체적인예로 FRP보In addition, as a specific example of the conventional repair / reinforcement composition of deteriorated concrete FRP beam

수/보강 조성물에서는 유리섬유를 주된 보강재로 하는 저압성형용 열경화성 수지의 적층 성형품으로 탄성계수는 보통 플라스틱 정도로 작아서 강성이 크게 요구되는 곳은 피해야하고, 콘크리트의 탈락방지 열화진행을 막기위한 콘크리트의 보호등에 적합하나 콘크리트와 물성치가 다르며 습한 표면에 부착력의 낮은 문제점이 있는 것이다.In the water / reinforcement composition, the laminated molding of thermosetting resin for low-pressure molding whose glass fiber is the main reinforcing material. The modulus of elasticity is usually as small as plastic so that the place where the rigidity is largely required should be avoided. It is suitable for the back, but the properties of the concrete is different and there is a problem of low adhesion to the wet surface.

복부족 또는 열화의 진행에 따른 콘크리트의 박리/탈락등에 의해 철근이 노출된 벽체에 대해서 지금까지 보수공법으로 가장 널리 사용되고 있으며, 결합재료 시멘트계 재료를 사용하여 경과 후 수축이 일어나지 않도록 할수 있으나, 수중에서 작업이 불가능하고 보강재로 요구되는 성능을 충족시키지 못하며, 특히 압축강도/굴곡강도와 보강재로서의 가장 중요한 구성요소인 접착강도가 유지되지 못하는 문제점이 있는 것이다,Walls exposed to rebar due to abdominal insufficiency or deterioration of concrete due to deterioration, etc. have been most widely used as a repair method until now, and contraction does not occur after use of cement material of bonding material. It is impossible to work and does not meet the required performance of the reinforcement, and in particular, the compressive strength / flexural strength and adhesive strength, which is the most important component as a reinforcement is not maintained,

그리고, 이러한 종래의 각종 토목 및 건축을 포함하는 몰탈 콘크리트의 시And, mortar concrete including such various conventional civil engineering and construction

설구조물,철물구조물을 보수/보강하는 조성물들은 구조물의 표면에 도장하는 피막성을 갖는 도장제 이거나, 몰탈에 첨가하는 첨가제 및 구조물을 마감처리 하는 마감제로서 시멘트콘크리트의 시설구조물에서는 표면에 형성되는 피막으로 하여금 대기중의 탄산가스의 침투를 지연시키어 고알카리성인 시멘트의 중화속도를 느리게 하므로서, 시멘트콘크리트의 시설구조물의 강도유지와 철근의 부식도 방지하여 시멘트콘크리트의 시설구조물의 수명을 보완하며 또한 철물구조물 및 금속구조물에서도 표면에 형성되는 피막에 의해 내부식성을 부여하여 손상을 예방하는 것으로 알려져 있다.Compositions for repairing / reinforcing snow structures and steel structures are coatings having a coating property on the surface of the structure, or additives added to mortar and finishing agents for finishing the structure. By delaying the penetration of carbonic acid gas into the air, it slows down the neutralization rate of highly alkaline cements, and also maintains the strength of cement structures and prevents corrosion of reinforcing bars, thereby improving the life of cement structures. Structures and metal structures are also known to prevent corrosion by imparting corrosion resistance by the film formed on the surface.

또한, 화산암의 자갈 및 모래가 사용되어 콘크리트의 열화현상이 가속되는경우에 중화를 지연시키는 효과가 우수하다고 알려져 있으나 이들의 조성물은 가격이 고가이고 보수/보강 대상 구조물의 열화상태에 따라 적정제품을 선정하고 이들 제품을 순서적으로 시공하여야 하는 시공상에 까다로움이 있어 시공비가 많이 요구되는등 경제적인 문제점이 큰부담으로 안고 있다.In addition, it is known that the effect of delaying neutralization when the deterioration of concrete is accelerated due to the use of gravel and sand of volcanic rock is excellent. However, their composition is expensive and appropriate products are selected according to the deterioration state of the structure to be repaired / reinforced. There is a heavy burden on the economic problems, such as high cost of construction due to the difficulty in selecting and installing these products in order.

또한, 종래에는 수중콘크리트구조물의 손상부위 등을 보수할때는 주로 거푸집을 설치하여 콘크리트 등의 손상부위 보상재료를 투입하고 보상재료가 굳힘되면 거푸집을 뜯어내는 공정으로 모든 보수작업이 이뤄지고 있기 때문에 이러한 수중콘크리트구조물의 보수 작업이 까다롭고 번거로우며, 작업 공정의 번거로움에 따른 인건비 증가와 전체적인 보수비 증가를 피하기 어려운 것이었다.In addition, conventionally, when repairing the damaged parts of the underwater concrete structure, mainly install the formwork to put the damage compensation material such as concrete, and when the compensation material is hardened, all the repair work is carried out by the process of tearing the form, such underwater concrete The maintenance work of the structure was difficult and cumbersome, and it was difficult to avoid the increase of labor cost and overall repair cost due to the cumbersome work process.
