摘要
华容县注滋口大桥12#墩钻孔灌注桩工程条件极差，经多种方法试验，最后采用了经济合理的冲击与回旋相结合的处理措施，成功地解决了上部大厚度、大体积的块石层及下部砂砾层整体失稳等技术难题。
It was successfully solved that the technological puzzles, integrally lack of stability with big thick and huge blocks of rock above and gravel beds below, adopting economically reasonable management measures of stroke and convolution combined finally, after many trial by many means in poor conditions of constructing borehole-perfusion stakes of pier No.12 of Zhuzikou Bridge, Huarong county.
