土围堰防渗施工技术研究

Research on Seepage Prevention Construction Technology of Earth Cofferdam

介绍了土围堰防渗施工技术的特点及其原理,分析其工艺流程和操作要点,对传统的土石围堰施工技术进行优化,利用土工膜和砂砾-细粒土掺和料弱抗渗能力实现了基坑干处作业,大幅缩短了工期,降低了安全及环保风险与工程成本。

The study introduces the characteristics and principle of soil cofferdam anti-seepage construction technology,analyzes its process flow and key points of operation,optimizes the traditional construction technology of soil cofferdam,realizes the dry operation of foundation pit with geomemofilm and weak impermeability of grit-fine soil admix,greatly shortens the construction period,reduces the safety and environmental protection risk and project cost.
