混凝土面板堆石坝涂覆型止水经济性研究

Economic Study on Coating Water Stop for Concrete Faced Rockfill Dams

为明确涂覆型止水在混凝土面板堆石坝施工中的经济性水平,构建涂覆型止水资源消耗量测算模型与经济性测算模型,并以某抽水蓄能水电站为案例,以写实法为基础,结合市场水平与水电工程造价体系,分析计算得到以“100延米”为单位的造价指标,并明确其与传统锚固型止水在造价上的区别。研究结果为涂覆型止水在水电工程混凝土面板堆石坝的推广提供技术与经济支撑。

In order to clarify the economic level of coated waterproofing in the construction of concrete face rockfill dams,a calculation model for the consumption of coated waterproofing resources and an economic calculation model were constructed.Taking a pumped storage hydropower station as a case study,based on the realistic method,combined with market level and the cost system of hydropower engineering,the cost index in units of“100 linear meters”was analyzed and calculated,And clarify the difference in cost between it and traditional anchor type waterstops.The research results provide technical and economic support for the promotion of coated waterproofing in concrete face rockfill dams in hydropower engineering.
