Construction period and scheme design of cutoff wall of phase Ⅱ cofferdam of Datengxia Water Conservancy Project

本文阐述了大藤峡水利枢纽工程二期围堰防渗墙工期紧、成墙造孔难度大、施工强度高的特点,合理分析了施工工期,提出了防渗墙分区施工设计方案,最大限度地满足技术可行、经济合理等方面的要求,为工程早日发挥效益奠定了基础。

In this paper,the construction period of the cofferdam cutoff wall of Ⅱ phase of the Datengxia Water Conservancy Project is tight,the dificulty of wall construction and hole construction,and the construction intensity is high.The construction period is reasonably analyzed,and the partition construction design scheme of cutoff wall is proposed to meet the requirements of technical feasibility and economic rationality to the maximum extent,so as to lay a solid foundation for the project to bring benefits into play as soon as possible.
