摘要
防渗加固是当前众多老旧大坝除险加固的重要内容之一,可有效延长坝体寿命,提高坝体运行安全性。文章以新疆红坑子水库1号副坝加固工程为实例,介绍了塑性混凝土防渗墙的位置、厚度、深度等参数设计,确定防渗墙设计在防浪墙槽孔下部。通过试验确定混凝土各材料配比,防渗墙投入使用后渗漏量下降了100%左右,效果显著,可为以后类似工程提供必要的技术参考。
The seepage control and reinforcement is one of the important contents of danger control and reinforcement for many old dams at present, which can effectively prolong the life of the dam body and improve the safety of its operation. Taking the reinforcement project of No. 1 auxiliary dam of Hongkengzi reservoir in Xinjiang as an example, the paper introduces the parameter design of the position, thickness and depth of the plastic concrete cutoff wall. It is determined that the cutoff wall is designed at the bottom of the groove hole of the wave-proof wall. The mix proportion of each material of concrete is determined through experiments, after the anti-seepage wall is put into use, the effect is remarkable, with the leakage amount is reduced by about 100%, which could provide the necessary technical reference for similar projects in the future.
