云南化念水库混凝土防渗墙施工关键技术要点

Key Technologies for Construction of Concrete Cutoff Wall of Huanian Reservoir in Yunnan Province

防渗技术是水利水电工程中至关重要的施工技术体系,对控制工程渗透稳定性有重要意义。以云南化念水库为例,针对坝体存在的水平渗透强烈、渗漏量大的问题,进行了混凝土防渗墙施工,并有效解决了渗漏问题。系统总结了防渗墙施工的关键技术要点,形成了一套较完善的防渗墙施工技术方法体系。

Anti-seepage technology is a very important construction technology system in hydraulic and Hydropower projects, and it is of great significance to control the seepage stability of the project. Taking Huanian Reservoir in Yunnan Province as an example, the concrete cut-off wall is constructed to solve the problems of intense horizontal seepage and large amount of seepage in the dam body, and the seepage problem is effectively solved. The key technical points of cut-off wall construction are systematically summarized and a set of relatively perfect construction technology and method system of cut-off wall is formed.
