Description
본 고안은 교면도막방수구조에 관한 것으로, 더욱 상세하게는 교량 콘크리트 노면에 특수 부직포와 교면도막 방수제(고무도막 방수제-클로로프렌)를 사용하여 형성되는 도막 방수층을 시공하여 눈이나 비로 인한 누수를 완전히 차단하여 교량 철골조와 철근부식 및 콘크리트 부식등을 사전에 예방하여 막대한 예산을 들여 설치한 교량을 오랫동안 튼튼하게 사용할 수 있는 구조를 갖도록 한 교면도막방수구조에 관한 것이다.The present invention relates to a cross-link waterproofing structure, and more specifically, to prevent leakage due to snow or rain by constructing a coating waterproof layer formed by using a special non-woven fabric and a cross-coated waterproofing agent (rubber waterproofing agent-chloroprene) on the bridge concrete road surface It is related to the bridge membrane waterproof structure which has the structure to be able to use the bridge installed with a huge budget for a long time by preventing bridge steel frame, reinforcing corrosion and concrete corrosion in advance.
일반적으로, 산업사회가 발전함과 동시에 차량의 이용 또는 증가하는 현대 사회에서 원활한 교통노선을 위하여 많은 교량을 설치하여 사용하고 있는 실정이다.In general, as the industrial society develops, many bridges have been installed and used for smooth transportation routes in the modern society, which uses vehicles or increases.
이렇게 막대한 예산을 들여 설치한 교량을 오랫동안 튼튼하게 사용하기 위하여 교량 콘크리트 노면에 방수층을 시공하여 눈이나 비로 인한 누수를 완전히 차단시켜 교량 콘크리트층 내에 들어있는 철근과 철판골조 등의 부식 및 콘크리트의 부식 등을 사전에 예방하기 위함이다. 현재 교량 콘크리트 노면에 시공되고 있는 방수시공방법은 침투방수와 시트방수 및 도막방수 등이 있다. 침투방수와 시트방수는 교면방수에 문제점이 많아 사용을 꺼리는 현상이며, 도막방수는 방수효과가 뛰어나 사용 추세가 급속도로 늘고 있는 실정이다.In order to use the bridge with huge budget for a long time, the waterproof layer is installed on the concrete road surface to completely prevent leakage due to snow or rain, and the corrosion of the reinforcing steel and steel frame in the bridge concrete layer and the corrosion of concrete This is to prevent in advance. The waterproof construction methods currently being applied to the concrete concrete road surface include penetration waterproofing, sheet waterproofing, and coating waterproofing. Infiltration waterproofing and sheet waterproofing are reluctant to use due to many problems with cross-linking waterproofing, and the waterproofing of coating is excellent due to its excellent waterproofing effect.
현재 사용하고 있는 교면도막방수(고무화 도막방수-클로로프렌)는 주성분이 고무(클로로프렌)이기 때문에 신율이 좋고 열에 매우 강하여 아스팔트의 열(150℃내지 180℃)에도 충분히 견디는 장점을 가지고 있는 반면 도막을 두껍게(2.5 내지 3mm)낼 수 없는 단점과 도막인장 강도가 약하여 아스팔트 포장시 아스팔트 속에 들어 있는 골재(끝이 뾰족함)에 방수층이 파손되는 단점을 가지고 있다.The currently used cross-coated waterproofing (rubber-free waterproofing-chloroprene) has high strength and high resistance to heat because it is rubber (chloroprene), which has the advantage of being able to withstand the heat of asphalt (150 ℃ to 180 ℃). The disadvantage of not being thick (2.5 to 3 mm) and the strength of the coating film is weak, which has the disadvantage of breaking the waterproof layer on the aggregate (pointed end) contained in the asphalt when asphalt is paved.
현재 시공되고 있는 교면도막 방수 시공법을 살펴보면 먼저 콘크리트 노면을 연마기로(솟 브라스트) 규정된 높낮이를 면정리를 한 후 깨끗하게 청소한다. 깨끗하게 청소된 교량 콘크리트 노면에 1차 침투 프라이머을 도포하고 도막이 건조되면 교면도막 방수제 상도(고무화 도막방수-클로로프렌) m2단위당 1.5kg을 2회에 걸쳐 헤라를 이용하여 도포하면 교면도막방수가 끝나게 된다.If you look at the waterproofing construction method of the currently used bridge coating film, the concrete road surface is polished with a grinder (so blast) and then cleaned. When the first penetration primer is applied to the clean concrete concrete road surface and the coating film is dried, applying 1.5 kg per m 2 unit of the coating film waterproofing agent (rubber-water-proofing-chloroprene) two times with HERA is applied to finish the bridge coating waterproofing. .
상기와 같은 종래의 교면도막방수구조는 도막 전체의 두께가 1 내지 1.5㎜ 밖에 되지 않아(방수제 주성분이 고무이기 때문에 2.5 내지 3㎜의 두께를 낼 수 없음) 방수층이 약할 뿐만 아니라 도막인장강도도 약하여(30㎏/㎡) 완벽한 방수층을 형성하는데 문제가 있었다. 즉, 아스팔트 포장시는 아스팔트 노면강도를 높이기 위하여 쇠바퀴를 구비한 롤러차량을 이용하여 아스팔트를 단단하게 다지는 과정에서 아스팔트속에 혼합되어 있는 골재(끝이 뾰족함)가 무거운 쇠바퀴에 눌려 교면도막 방수층을 파손하는 일이 자주 발생할 뿐만 아니라 차량의 통행시 교량의 흔들림으로 발생되는 충격에 의해 방수층에 크랙이 쉽게 발생되어 누수의 원인이 된다는 문제점이 있었다.The conventional cross-linked waterproofing structure as described above has only a thickness of 1 to 1.5 mm (the main component of the waterproofing agent can not be 2.5 to 3 mm thick because it is rubber), and not only the waterproof layer is weak, but also the film tensile strength is weak. (30 kg / m 2) There was a problem in forming a perfect waterproof layer. That is, when paving asphalt, the aggregates (pointed) mixed in the asphalt are pressed by heavy metal wheels in the process of hardening the asphalt by using a roller vehicle equipped with a wheel to increase the asphalt road strength. In addition to the frequent occurrence of the breakage, there was a problem that a crack is easily generated in the waterproof layer due to the shock generated by the shaking of the bridge during the passage of the vehicle, causing leakage.
본 고안은 상기와 같은 종래의 문제점을 고려하여 안출한 것으로서, 그 목적은 교량 콘크리트 노면에 완벽한 도막방수층을 시공하여 눈이나 비로 인한 누수를 확실히 차단하여 교량의 철근, 철판골조 및 콘크리트의 부식을 예방히고 차량통행시 교량의 흔들림으로 인한 크랙발생을 예방하여 막대한 예산을 들여 설치한 교량이 오랫동안 튼튼하게 사용될 수 있도록 하는 교면도막방수구조를 제공하는 것이다.The present invention was devised in consideration of the conventional problems as described above, and its purpose is to construct a perfect film waterproofing layer on the bridge concrete road surface to reliably block leakage due to snow or rain to prevent corrosion of reinforcing bars, steel frames and concrete of the bridge. It is to provide a cross-coated waterproofing structure that prevents cracks caused by the shaking of the bridge when passing the vehicle, so that the bridge installed with a huge budget can be used for a long time.

When the cross-coated waterproofing structure according to the present invention having the configuration as described above is completed, even if the asphalt 20 is laid on the fourth waterproofing layer 19 to a predetermined thickness and firmly compacted by a roller vehicle, the thickness of the waterproofing structure is sufficient. It is thick and has a buffering force by the first and second nonwoven fabrics 16 and 18, so that it is possible to reliably prevent the waterproof layer from being damaged by the pointed aggregate mixed in the asphalt 20, as well as the fiber glass. Since the net 14 protects the waterproof layer with lateral force, cracks may be prevented from occurring in the waterproof layer by vibration of a bridge that is shaken by traffic of a vehicle, and a hole may be formed in the first and second nonwoven fabrics 16 and 18. 16a) and 18a are formed to prevent wrinkles or peeling of the nonwoven fabric even in the stretching phenomenon caused by the temperature change. In addition, the bridge film waterproof layer structure according to the present invention is not limited to the bridge can be applied to the waterproof of roofs of general buildings.
교량 콘크리트(10)의 노면에 망으로된 화이버그라스와 일정간격으로 통공이 형성된 특수 부직포(16)(18)를 사용하여 교면도막방수층을 형성시킴으로서 방수층 두께를 필용한 두께로 시공할 수 있을 뿐만 아니라 교면도막 인장강도를 획기적으로 높여 아스팔트 포장시 아스팔트 강도를 높이기 위하여 골재가 교면도막방수층을 파손하는 일이 없도록 하였으며 교량노면 위에 차량이 달릴 때 교량의 흔들림으로 인한 충격을 흡수하여 도막방수층의 크랙발생을 방지하고 열팽창으로 인한 수축현상을 방지하므로 완벽한 방수층을 형성시켜 운이나 비로 인한 누수를 완벽하게 차단하여 교량의 철근 및 철골조의 부식과 콘크리트의 부식을 사전에 예방하여 교량의 유효수명을 현저히 향상시킬 수 있는 효과를 갖는다.By using the fiberglass lath on the road surface of the bridge concrete (10) and the special nonwoven fabric (16) (18) having holes formed at a predetermined interval, the cross-coated waterproof layer is formed to not only be able to be constructed to the required thickness of the waterproof layer. In order to increase the strength of asphalt when paving the asphalt, the aggregate film does not break the bridge's waterproof layer and absorbs the impact of the bridge's shaking when the vehicle runs on the surface of the bridge. It prevents shrinkage due to thermal expansion and forms a perfect waterproof layer to completely block leakage due to luck or rain, thereby preventing corrosion of reinforcing steel bars and steel frames and corrosion of concrete in advance, thereby significantly improving the effective life of the bridge. Has the effect.
