平谷区泃河新城段(上纸寨—洳河汇入口)治理工程设计过程中在北方缺水地区建设防洪兼具景观功能河道方面存在一些问题,经分析研究提出了以工程措施减少河道渗漏来维持生态景观水位的设计思路。通过比选硬化处理减渗、土工膜减渗、黏土防渗、膨润土防水毯防渗等工程措施,选用施工简便、工期短、可抵抗一般地形沉降、绿色环保的减渗材料,以及适合北京发展需要的膨润土减渗毯,并在此基础上进行河道断面的减渗设计。

There are some problems in the design of flood control and landscape function river course in the North water-deficient area of Pinggu District in the course of the control engineering design of the new section of Juhe River(Shangzhizhai-Junhe confluence entrance). Based on the analysis and research, we put forward the design idea of maintaining the ecological landscape water level by reducing the seepage of river course by engineering measures. Through comparison and selection of engineering measures such as hardening treatment, geomembrane, clay and bentonite waterproof blanket, the seepage reduction materials with simple construction, short construction period, resistance to general topographic settlement and green environmental protection are selected. Otherwise bentonite impermeable blanket which is suitable for Beijing's development needs is also selected. Based on that, seepage reduction design of river section is carried out.
