Abstract

Riverbank revetments are installed to increase the stability, while preventing scouring, and utilize the rivers; their construction is prioritized to secure dimensional safety that can withstand flooding. Existing revetment technologies employ use of rocks, gabions, and concrete. However, stone and gabions are easily erosion and destroyed by extensive flooding. Though the materials used in concrete technology possess strength and stability, the strong base adversely affects the aquatic ecosystem as components leach and remain in water for a long time. This serves as an environmental and ecological issue as vegetation does not grow on the concrete surface. This study introduces multi-layer porous riverbank revetment technology using biopolymer materials extracted from castor oil. Results obtained from this study suggest that this technology provides greater dimensional stability as compared to existing technologies. Moreover. it does not release toxic substances into the rivers. Multiple experiments conducted to review the application of this technology to diverse river environments confirm that stability is achieved at a flow velocity of 8.0 m/s and maximum tractive force of 67.25 kgf/m2 (659.05 N/m2).

하천의 안정성과 이용도를 높이기 위하여 설치하는 하천 호안이 최우선으로 여기는 가치는 홍수에 견딜 수 있는 치수적인 안전성 확보이다. 이러한 구조물은 물의 하천의 안정성을 확보하면서 호안의 세굴을 막기위해 설치된다. 기존에 하천에 설치된 호안 기술은 사석, 돌망태 및 콘크리트 등으로 구성되어 있다. 하지만 사석 및 돌망태 기술은 급격한 홍수로 인해 쉽게 유실 및 파괴되는 단점을 지니고 있으며, 콘크리트 기술은 소재의 안정성은 강하지만, 물속에 오랜 시간동안 존재할 경우 수생태계에 악영향을 미치는 강염기가 약 10년간 용출되고, 콘크리트 표면에 식생이 성장하지 못하기 때문에 환경 및 생태적인 이유로 문제가 되고 있다. 이에 피마자유에서 추출된 바이오폴리머 소재를 활용하여 다층다공성 하천호안보호기술을 개발하였으며, 한국건설기술연구원 안동하천실험센터에서 실규모 하천실험을 통해 수리학적 안정성 검토결과, 유속 8.0 m/s 및 최대 허용 소류력은 67.25 kgf/m2 (659.05 N/m2)에서 수리적인 안정성을 확인하였다.
