浅谈土石坝套井回填防渗补强施工技术

On Construction Technology of Earth and Rock-fill Dam Set Well Backfilling Anti-seepage Reinforcement

大坝渗漏是众多小型水库普遍存在且较为突出的问题,直接影响水库工程正常、安全运行。套井回填防渗补强技术具有机械设备简单、施工方便、工程量小、工效高、造价低及防渗效果好等优点,在解决许多土石坝的渗漏问题中发挥了显著作用。本文详细介绍了套井回填施工方法,以期为类似工程提供参考。

Dam seepage is a common and more prominent problem for many small reservoirs, which directly affects normal and safe operation of reservoir project. Set well backfilling anti-seepage reinforcement technology has advantages of simple mechanical equipment, convenient construction, low engineering quantities, high efficiency, low construction cost, good anti-seepage effect, etc., which plays significant role in solving seepage problem of many earth and rock-fill dam. Set well backfilling construction method is introduced in the paper in detail in order to provide reference for similar projects.
