| 摘 要： | 针对深厚卵砾石层中以往压浆施工工艺的不足，提出了改进方法:当卵砾石层充填物为细粒土时，采用孔眼直径小、间距小的套管；当其为粗粒土时，则用孔眼直径大、间距大的套管。通过现场试验对比分析，该工艺可以提高工效，保证质量。

| Abstract: | For the insufficiency in former grouting construction technology in deep gravel layer,this paper puts forward improvement method.When gravel layer is filled with fine-grained soil,small-hole-diameter and small-distance casing tube shall be adopted;when it is filled with coarse-grained soil,large-hole-diameter and large-distance casing tube shall be adopted.Through comparative analysis from site test,this new technique can improve efficiency and ensure quality in construction. |

| Keywords: | gravel layer sealing grouting construction technology casing hole working efficiency quality |
