| 摘 要： | 二次压浆小桩在小桩成桩后，通过预埋的压浆管对桩端及桩侧高压注入水泥浆液，使桩端持力层得以固结密实，桩侧摩阻力增大，提高地基土的整体抗剪强度，防止液化土层流动，从而达到抗震加固的目的。文章介绍了用二次压浆小桩对山东荷泽电厂1号机组电除尘改造工程的地基处理方法及良好效果。

| Abstract: | Small secondary grouting pile is used to inject cement slurry to pile tip and side through embedded grouting pipe under high pressure so as to consolidate tip supporting layer and increase side frictional resistance,to improve overall shear strength of foundation soil,and to prevent hydraulic soil flow and thus realize seismic reinforcement.This paper introduces foundation treatment method and good effect of dedusting reconstruction project of Shandong Heze Power Plant No.1 Unit using small secondary grouting pile. |
