Construction of Digging Sheet Pile Wall and Pile Well Artificially Under Special Geological Condition

在淤泥质粘土、粉砂层成饱和且在不同涌水量状态下,采取缩短循环开挖深度、回填柔韧性材料、下钢套筒、帷幕注浆等多种施工方案,成功地解决了护壁施工过程中若干工程问题。

When the silt clay or silty sand layer is in saturation sate and under different water discharges, engineers adopt some measures to deal with the construction problems of retaining wall, such as shorting the depth of circularly digging, backfilling flexile material, using steel sleeve and curtain grouting, finally successfully solve these construction problems.
