Description

저수 구조물의 방수 시공방법{EXECUTION METHOD OF WATERPROOF}Waterproof construction method of water storage structure {EXECUTION METHOD OF WATERPROOF}

도 1은 본 발명에 따른 방수 시공방법을 나타낸 공정블록도.1 is a process block diagram showing a waterproof construction method according to the present invention.

본 발명은 저수 구조물의 방수 시공방법에 관한 것으로, 더욱 상세하게는 흡수성, 압축강도 및 부착강도를 향상시켜 저수 구조물 및 도막의 균열로 인한 누수현상을 방지함으로써 방수기능을 향상시킬 수 있는 저수 구조물의 방수 시공방법에 관한 것이다.The present invention relates to a waterproof construction method of a storage structure, and more particularly, to improve the absorbency, compressive strength and adhesion strength of the storage structure that can improve the waterproof function by preventing water leakage due to cracks in the storage structure and coating film. It relates to a waterproof construction method.

일반적으로 저수 구조물에 대한 방수는 알칼리계 실리케이트로 이루어지는 침투성 방수제가 많이 사용되고 있으며, 이러한 알칼리계 실리케이트는 표면장력이 낮게 제조되지만, 콘크리트의 주성분인 칼슘이온과 매우 빠른 속도로 반응하여 칼슘실리케이트를 형성한다. 이렇게 형성된 칼슘실리케이트는 불용성이면서 화학적으로 매우 안정한 산화물로서 콘크리트 표면을 보호해 줄 수 있지만, 흡수량이 0.3g/㎠에 불과하여 콘크리트 내부에 깊숙이 침투하지 못하는 문제가 있다.In general, the waterproofing structure for the water storage structure is made of a permeable waterproofing agent composed of alkali silicates. Although the alkali silicate is manufactured with low surface tension, it reacts with calcium ions, which is the main component of concrete, at high speed to form calcium silicates. . Thus formed calcium silicate is insoluble and chemically very stable oxide can protect the surface of the concrete, but there is a problem that does not penetrate deep into the concrete because the absorption amount is only 0.3g / ㎠.

또한 칼슘실리케이트와 같은 발수성물질은 콘크리트에 침투 후 반응하여 발수력을 발생시킴으로써 물의 침투를 차단하는 것으로, 수압이 작용하는 저수 구조물에서와 같이 발수력보다 수압이 크게 작용하는 경우에는 발수력의 한계로 인하여 적용하기 어려우며, 열 및 자외선 등에 의한 분해에 의해 장기적이 내구성능을 보증하기 어려우며, 특히 기존의 침투성 방수제들의 경우 콘크리트 표면이 강한 친유성층을 형성함으로 인하여 콘크리트 표면에 2차적인 코팅을 할 때 접착성이 현저히 떨어지는 단점과 내수압에 약하고 자외선에 누출될 경우 쉽게 분해되는 단점들이 있으며 내화학적 성능이 열악하여 황산과 염산 등에 노출이 될 경우 쉽게 분해되어 그 기능을 발휘하지 못하는 문제가 있었다. In addition, water-repellent substances such as calcium silicate block water penetration by reacting after infiltration into concrete to generate water repellency. When water pressure is greater than water repellency, such as in a water-retained structure, the limit of water repellency is limited. It is difficult to apply due to its dissolution by heat and ultraviolet rays, and it is difficult to guarantee long-term durability performance.In particular, in case of conventional permeable waterproofing agents, when the secondary surface is coated on concrete surface by forming strong lipophilic layer on concrete surface There are disadvantages of poor adhesion and weakness in water pressure, and easily decompose when leaked in ultraviolet light. The chemical resistance is poor, and when exposed to sulfuric acid and hydrochloric acid, it is easily decomposed to exhibit its function.

본 발명은 상기한 종래기술의 문제점을 해결하기 위한 것으로, 그 목적은 콘크리트에 방수 도포시 흡수량을 증대시킴으로써 콘크리트와의 부착강도 및 방수처리후의 압축강도를 향상시켜 균열에 의한 누수를 방지할 수 있고, 방수기능 및 내구성을 향상시켜 사용 수명을 연장할 수 있는 저수 구조물의 방수 시공방법을 제공하는데 있다.The present invention is to solve the above problems of the prior art, the purpose of which is to increase the amount of water absorbed during the waterproof coating on the concrete to improve the adhesion strength with the concrete and compressive strength after waterproofing to prevent leakage due to cracks It is to provide a waterproof construction method of a water storage structure that can extend the service life by improving the waterproof function and durability.

이하, 본 발명에 따른 저수 구조물의 방수 시공방법의 바람직한 실시예를 첨부한 도면에 의거하여 상세하게 설명한다. 도 1은 본 발명의 방수 시공방법을 나타낸 공정도로서, 도시된 바와 같이 본 발명의 방수 시공방법은, 전처리공정(10), 1차 방수조성물 도포공정(20), 2차 방수조성물 도포공정(30), 1차 도료 도포공정(40) 및 2차 도료 도포공정(50)을 순차적으로 수행하여 이루어진다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the waterproof construction method of the water storage structure according to the present invention will be described in detail. 1 is a process chart showing the waterproof construction method of the present invention, as shown in the waterproof construction method of the present invention, the pre-treatment step 10, the first waterproof composition coating step 20, the second waterproof composition coating step (30) ), The first paint coating process 40 and the second paint coating process 50 is performed by sequentially.

전처리공정(10)은 방수 및 방식 성능을 저해하는 이물질을 콘크리트 방수도포면으로부터 제거하기 위해 청소를 실시하는 것으로, 고압수 세척방법을 이용하여 콘크리트 방수도포면의 이물질 및 단차를 제거하고, 방수도포면의 모세관을 노출시켜 방수조성물과 콘트리트의 부착력을 증대시킬 수 있도록 한다.The pretreatment process (10) is to clean to remove the foreign matter from the concrete waterproof coating surface to hinder the waterproof and anticorrosive performance, to remove the foreign matter and step on the concrete waterproof coating surface by using a high-pressure water washing method, the capillary of the waterproof coating surface Exposed to increase the adhesion of the waterproof composition and concrete.

이어서 1차 방수조성물 도포공정(20)은, 규산질계 분말형 방수제 72~76중량％, 결합제 12~16중량％, 물 12중량％를 균일하게 혼합한 제1 방수조성물을 방수도포면에 롤러로 균일하게 도포하는 공정으로서, 전처리공정(10) 후 일정시간 경과하여 방수도포면의 습도가 60~80％인 상태에서 실시하는 것이 바람직하다. 상기 습도가 60％보다 낮을 경우, 흡수량이 지나치게 낮고, 습도가 80％보다 높을 경우, 콘크리트와의 결합력이 저하된다.Subsequently, the primary waterproofing composition applying step 20 uniformly mixes the first waterproofing composition of 72-76% by weight of the siliceous powder-based waterproofing agent, 12-16% by weight of the binder, and 12% by weight of water with a roller on the waterproof coating surface. It is preferable to perform it in the state which the humidity of a waterproof coating surface is 60 to 80% after a predetermined time after the pretreatment process 10 as a process to apply | coat easily. When the humidity is lower than 60%, the absorption amount is too low, when the humidity is higher than 80%, the bonding strength with the concrete is lowered.

상기 규산질계 분말형 방수제로는, 방수제 메이커인 "세레시트사"가 제조한 세레켐 씨알65(Cerecem CR65)등을 사용한다. 세레켐 씨알65는 침투성 결정체 방수제인 실리카 샌드(Silica Sand)와 30여 종류의 활성화합물질과 아크릴 폴리머(Acrylic Polymer)가 분말형태로 혼합된 방수제로서 습기가 있는 상태에서도 시공이 가능하고 들뜸 현상이나 크랙 발생이 전혀 없으며, 고유의 첨가제 작용으로 모세관과 공극을 수밀하게 하여 물분자의 침투를 막는다. As the siliceous powder-based waterproofing agent, Cerecem CR65 manufactured by Ceresitic Co., Ltd., a waterproofing agent manufacturer, is used. Cerechem SAL 65 is a waterproofing agent mixed with silica sand, which is a permeable crystal waterproofing agent, and 30 kinds of activated polymer and acrylic polymer in powder form. There is no crack at all, and the inherent additive action makes the capillary tube and the pores tight, preventing water molecules from penetrating.

또한 세레켐 씨알65는 강한 수압을 지탱하면서도 지속적으로 침투하는 화학 작용 성분을 가지고 있으며, 이러한 침투성으로 인하여 지하실이나 벽에 아무리 강한 수압이 작용해도 우수한 방수성능을 발휘하고, 염분, 알카리등 어떠한 기후 조건에서도 물리적, 화학적 특성이 우수하다. 한편, 결합제로서는 역시 방수제 메이커 "세레시트사"가 제조한 세레시트 에이씨2000(Ceresit AC2000)등을 사용하는 것이 좋고, 일반적으로 결합제로 알려진 본드를 사용하여도 좋다. In addition, Cerechem CE 65 has a strong chemical pressure that continuously penetrates while maintaining strong water pressure. Due to this permeability, it exhibits excellent waterproofing performance no matter how strong water pressure is applied to the basement or walls, and any weather conditions such as salt and alkali. Even physical and chemical properties are excellent. On the other hand, it is preferable to use Ceresit AC2000 manufactured by the waterproofing agent maker "Serexite" etc., and the bond generally known as a binder may also be used.

2차 방수조성물 도포공정(30)은, 규산질계 분말형 방수제 72~76중량％, 결합제 12~16중량％, 물 9중량％, 방수액 3중량％를 균일하게 혼합한 제2 방수조성물을 방수도포면에 롤러로 균일하게 도포하는 공정으로서, 1차 방수조성물 도포공정(20) 후 일정시간 경과하여 방수도포면의 습도가 60~80％인 상태에서 실시하는 것이 바람직하다. 상기 습도가 60％보다 낮을 경우, 흡수량이 지나치게 낮고, 습도가 80％보다 높을 경우, 콘크리트와의 결합력이 저하된다.The secondary waterproof composition coating step 30 is a waterproof coating surface of a second waterproof composition in which 72 to 76% by weight of siliceous powder type waterproofing agent, 12 to 16% by weight of binder, 9% by weight of water, and 3% by weight of waterproofing liquid are uniformly mixed. It is preferable to perform it in the state which the humidity of a waterproof coating surface is 60 to 80% after a predetermined time after the primary waterproofing composition application process 20 as a process of apply | coating uniformly with a roller. When the humidity is lower than 60%, the absorption amount is too low, when the humidity is higher than 80%, the bonding strength with the concrete is lowered.

또한 상기 규산질계 분말형 방수제와 결합제는 제1 방수조성물과 동일한 세레켐 씨알65과 세레시트 에이씨2000을 사용하는 것이 좋고, 방수액으로는 현재 시판되고 있는 일반적인 고농축 방수액이라면 모두 사용 가능하다.In addition, the siliceous powder type waterproofing agent and the binder may use the same Cerechem CE 65 and Cereceit AC 2000 same as the first waterproofing composition, and any waterproofing liquid may be used if it is a general high concentration waterproofing liquid currently on the market.

이어서 1차 도료 도포공정(40)은, 무용제 에폭시를 2차 방수조성물 도포공정(30) 후 방수 도포면이 완전 건조된 상태에서 롤러로 균일하게 도포하여 이루어지는 것으로, 1회의 도포를 실시하고, 2차 도료 도포공정(50)은, 무용제 에폭시를 1차 도료 도포공정(40) 후 방수 도포면이 완전 건조된 상태에서 롤러로 균일하게 도포하여 이루어지는 것으로, 2회의 도포를 연속하여 실시한다. 이때, 상기 무용제 에폭시는 현재 시판되고 있는 슈퍼폭시 500을 사용하는 것이 좋다. 슈퍼폭시 500은 식수탱크 내면 도장용으로 개발된 무용제형 에폭시 수지 도료로서 경화가 빠르면서 방수 도포면과의 접착력 및 내구력이 우수한 도료이다. Subsequently, the primary paint coating step 40 is obtained by uniformly applying a solvent-free epoxy to a roller in a state where the waterproof coating surface is completely dried after the secondary waterproofing composition applying step 30. The coating application step 50 is obtained by uniformly applying a solvent-free epoxy to a roller in a state where the waterproof coating surface is completely dried after the primary coating application step 40, and performs two coatings in succession. At this time, the solvent-free epoxy is preferably used Superpox 500 commercially available. SuperPoxy 500 is a solvent-free epoxy resin paint developed for painting the inner surface of drinking water tanks. It is a fast curing agent and excellent in adhesion and durability to waterproof coated surfaces.

상기 표로부터 알 수 있는 바와 같이 실시예1의 경우가, 종래예에 비하여 흡수량, 압축강도 및 부착강도 모두 월등하게 양호한 것으로 나타났고, 실시예2의 경우는, 결합제의 비중이 높아짐에 따라 실시예1에 비하여 부착강도는 높지만, 흡 수량은 낮았으며, 실시예3의 경우는, 결합제의 비중이 낮아짐에 따라 흡수량은 실시예1에 비하여 높지만, 부착강도는 낮은 것으로 나타났다.As can be seen from the above table, in the case of Example 1, the absorption amount, the compressive strength, and the adhesion strength were much better than those in the prior art, and in the case of Example 2, the specific gravity of the binder was increased. The adhesion strength was higher than that of 1, but the water absorption was low. In Example 3, as the specific gravity of the binder was lowered, the absorption amount was higher than that of Example 1, but the adhesion strength was low.

한편, 비교예1은 결합제의 비중이 지나치게 높아짐에 따라 흡수량이 종래예에 비하여 별 차이가 없었으며, 비교예2의 경우는 결합제의 비중이 지나치게 낮아짐에 따라 종래예에 비해 흡수량은 높지만 부착강도는 별 차이가 없었다.On the other hand, in Comparative Example 1, as the specific gravity of the binder is too high, there is no difference in absorption compared to the conventional example, and in Comparative Example 2, as the specific gravity of the binder is too low, the absorption is higher than the conventional example, but the adhesion strength is There was no difference.
