铜仁市羊尾舟村排洪工程设计方案探讨

铜仁市羊尾舟村由于峡谷平地地势、山区沟渠暴雨短时汇流集中等特点,存在较大山洪灾害风险,采取合适的工程措施提高防洪标准保护居民及农田安全尤为重要。结合羊尾舟山区沟渠防洪现状及建设内容,设计优选清淤疏浚与新建排洪渠和交通桥相结合的治理方案。论证分析成果表明,原自然沟渠经清淤及开挖新建排洪渠工程措施处理后,沟渠防洪断面得到有效拓宽,行洪能力得到较大提升,在保留沟渠原始生态的基础上实现合理整治。研究成果可为乡村振兴山洪灾害防治工程规划建设提供参考。

Yangweizhou village in Tongren City has a great risk of mountain flood disaster due to the characteristics of the terrain of the valley flat and the short-time confluence of the heavy rain in the mountain gully,so it is particularly important to take appropriate engineering measures to improve flood control standards to protect residents and farmland.According to the present situation and construction content of ditch flood control in Yangweizhou mountain area,the treatment scheme of dredging and dredging combined with new flood discharge channel and traffic bridge is designed and optimized.The results of demonstration and analysis show that after the engineering measures of dredging and excavating the newly built flood discharge channel of the original natural ditch,the flood control section of the ditch has been effectively widened,the flood discharge capacity has been greatly improved,and reasonable regulation has been realized on the basis of preserving the original ecology of the ditch.The research results can provide reference for the planning and construction of rural revitalization mountain torrent disaster prevention and control project.
