摘要
防渗漏加固是水利工程堤坝施工中不可忽视的重要环节,对于提高堤坝的稳定性和防渗性能具有至关重要的作用.基于此,文章针对水利工程堤坝施工中的防渗漏加固施工技术展开研究.结合需求,采用高压填充注浆+水平防渗+钢围堰导流管相结合的防渗漏加固形式,经过施工前准备、水平防渗、安装钢围堰导流管以及高压填充注浆加固,完成了堤坝施工中的防渗漏加固工程.实际应用结果表明,加固施工后,堤坝 6 个月内未出现渗漏现象,且堤坝高程真空度大于最小限值,符合施工技术规范,采取的防渗漏加固技术具有良好的效果.
Abstract
Anti-seepage reinforcement is an important part of dam construction in water conservancy project,which plays an important role in improving the stability and anti-seepage performance of dam.Based on this,this paper studies the anti-leakage reinforcement construction technology in the dam construction of water conservancy projects.Combined with the demand,the anti-seepage reinforcement form of high-pressure filling grouting+horizontal anti-seepage+steel cofferdam diversion pipe is adopted.After pre-construction preparation,horizontal anti-seepage,installation of steel cofferdam diversion pipe and high-pressure filling grouting reinforcement,the anti-seepage reinforcement project in dam construction is completed.The practical application results show that after the reinforcement construction,there is no leakage phenomenon in the dam within 6 months,and the vacuum degree of the dam elevation is greater than the minimum limit value,which conforms to the construction technical specifications,and the anti-leakage reinforcement technology adopted has good effect.
