超长粉喷桩施工中的硬夹层处理工艺

The Technology of Hard Inter-calation Treatment During the Installation of Extra Long Powder Mixing Piles

粉喷桩施工一般采用连续喷粉、连续搅拌施工工艺 ,但当施工中遇到硬夹层时就必须酌情处理 ,本文以某高速公路 H标段路基软土处理为例 ,阐述对这一方法的灵活运用。

The technology of continuous spraying,and mixing is generally use in the installation of powder mixing piles,but it should be modified in cases of hard inter calation is encountered.An example used in a super high way is introduced.
