浅析稀水地区河道生态治理中的防渗技术措施

Preliminary Analysis of Seepage Control Measures in River Ecological Management in water-poor Area

本文简要总结了目前常用的几种防渗技术,分析了各自的原理、优缺点以及对河道的生态影响。以河南稀水地区的河道生态治理工程为例,笔者从河道生态防渗着手,初步拟定了HDPE土工膜、膨润土防水毯、黏土防渗三种防渗方案。同时,通过防渗处理前后渗漏量的计算,进一步对比了三种防渗方案,为河道生态治理中的防渗技术措施提供参考。

This paper briefly summarizes several commonly used seepage control technologies,and analyses their principles,advantages and disadvantages,as well as their ecological impact on the river.Taking the river ecological management project in Henan's water-poor area as an example,the author starts from the river ecological anti-seepage,and preliminarily formulated three anti-seepage schemes of HDPE geomembrane,bentonite waterproof blanket and clay anti-seepage.At the same time,through the calculation of leakage before and after anti-seepage treatment,three anti-seepage schemes are further compared to provide reference for anti-seepage technical measures in river ecological management.
