宁乡县楚江中游项目区崩岗治理中水利工程设计(含CAD图)(选题审批表,任务书,开题报告,中期检查表,论文21800字,CAD图纸6张合一)CHUJIANG MIDDLE REACHES PROJECT IN NINGXIANG COUNTRY COLLAPSE MANAGMENT OF WATER CONSERVANCY PROJECT ENGINEERINGDESIGN摘要:本次崩岗治理设计是针对宁乡县楚江中游项目区出现中小型崩岗及水土流失较为严重的区域,对部分不稳定的山体进行整治,以此达到水土保持的目的。主要包括对面积较大的崩岗进行分梯级治理,根据地形上、下设置截排水沟,根据崩岗形状设置挡土墙、谷坊及开发成梯田等,对于集雨面积较大且植被稀疏地域采取封育补植措施。本次设计从技术和经济上是可行的。 关键词:挡土墙;截排水沟;谷坊;崩壁台阶 Abstract:The collapse in the management design is for regulating the ChuJiang middle reaches project in NingXiang country that exists small and medium-sized collapse and the area where there is a serious water and soil loss ,and part of the mountain unstable to keep soil and water conservation..Mainly including controlling the large area of collapse by points cascade and setting section drain according to the topography. To set the check dam and retaining wall and develop into terrace according to the collapse shape. To take the measures of enclosure for plant for the rainwater-collecting area and sparse vegetation region. The design is technologyly and economyily feasible. Key words: retaining wall;Section drain;check dam ;Collapse steps wall
