摘要
潦河水生态综合治理工程中的拦河坝为了满足溢流及蓄水需求,符合现阶段河道治理要求,提升景观效果。在治理段河道选择合适坝址优选工程布局,并进行相应坝型比选。为此,在工程桩号5+050处的2#景观坝高1.20 m,采用混凝土固定坝,同时考虑生态景观性,采用“鱼鳞形”跌水堰。1#坝位于桩号3+500处拟建坝高3 m,需采用活动坝,目前低水头可选挡水建筑物主要有液压升降坝、橡胶坝、水力自动翻板坝等3种形式。选择这三种坝型经技术经济比选,结果采用液压升降坝。这一拦河坝坝址与坝型比选实践可为类似水生态河道治理提供借鉴参考。
The barrage in the comprehensive ecological management project of Liaohe River meets the requirements of the overflow and storage and meets the requirements of river management at the present stage.It also improves the landscape effect.The appropriate dam site is selected to optimize the engineering layout in the treatment section,and the corresponding dam type is compared.For this reason,the height of the 2#landscape dam at the project pile number 5+050 is 1.20 m.The dam is fixed with concrete.At the same time,the fish scale shape drop weir is adopted considering the ecological landscape.1 dam is located at pile 3+500.The proposed dam is 3 m high and active dam needs to be used.At present,the optional water retaining buildings with low head mainly include three forms that are hydraulic lifting dam,rubber dam and hydraulic automatic overturning dam.These three types of dam are selected by technical and economic comparison.The result is hydraulic lifting dam.This practice of comparing dam site and dam type can provide reference for similar water ecological river management.
