小清河划界成果

1、 小清河划界成果本次选取的小清河划界河段范围为清河区小清河尹家堡子村至小清河汇入清河口，总长13.5km。划界范围：有堤段河道管理范围和保护范围划界范围内现状有堤段位于XQH0+000-XQH1+401两岸，起点是小清河汇入清河口，终点是小清河入口，两岸堤长2554m；对于现状有堤防段，需明确护堤地边界线，堤防工程管理范围和保护范围。此段堤防设计防洪标准为20年一遇，工程级别为4级，根据堤防工程设计规范（GB50286-2013）中的规定选取，本项目堤防迎水侧护堤地宽度取为距堤脚5m，堤防背水侧护堤地宽度取为距堤脚5m，堤防工程背水侧保护范围宽度取为距背水侧护堤地边界线50m，迎水侧由于该段规

2、划河道宽多数在30m45m之间，堤防迎水侧保护范围均位于河道管理范围内，因此迎水侧不设保护范围边界线。堤防管理范围为背水侧护堤地边界线至迎水侧护堤地边界线。无堤段河道管理范围 护岸段河道管理范围在铁岭市清河区小清河(货郎屯沟)重点山洪沟防洪治理工程初步设计桩号为左岸XLK0+000XLK0+200，XLK0+527XLK0+667，XLK1+100XLK1+812，XLK1+820XLK3+202，XLK3+685XLK4+059，XLK4+062XLK4+362，XLK4+454XLK5+049，SLK0+115SLK0+415，SLK0+729SLK1+029，SLK1+435SLK1+7

4、平原河段，按照设防标准对应的洪水位或历史最高洪水位进行划定，同时兼顾上下游和左右岸的岸线走向，综合进行划定，划界应不能缩窄原有管理范围，且满足河道行洪和管理保护要求，因此，本次划界以自然岸坎线为基准线，自然岸坎线外延10m即为河道管理范围。对于紧邻公路段的河道，管理范围视现场情况而定，可在10m范围内作调整。涉河水利建筑物管理范围水库管理范围划界河道范围内有1座前马水库。按照辽宁省河湖和水利工程管理范围划定补充技术指导意见（试行）有关规定，划定上其管理范围为上游边界以外100m，上游边界以外150m，左岸紧邻山体，以山体为界，右岸以边界以外100m。6河道管理范围线界桩及标示牌坐标表表1-1
