摘要
Abstract
Small water gates are numerous and widely distributed in Tongzhou District,Beijing,which play a crucial role in flood and drought disaster prevention,farmland irrigation,ecological water supplement,and other fields.Due to factors such as long construction time and insufficient maintenance,some small water gates have encountered durability problems including excessive concrete carbonation,freeze-thaw erosion,steel bar corrosion,and gate rust,which threaten engineering safety and regional water security.This paper systematically summarized the influencing factors of small water gate durability from aspects of material degradation,structural aging,external environment,and management maintenance.By analyzing the safety appraisal reports of water gates in Tongzhou District,it was found that water gates with concrete carbonation depth exceeding the protective layer accounted for 40%,the steel bar corrosion rate reached 41.2%,and the freeze-thaw erosion rate reached 41.2%.According to the current situation of small water gates,technical and management approaches to improve their durability were proposed.The research results can provide reference for similar projects nationwide and contribute to the high-quality development of water conservancy infrastructure.关键词
