摘要
结合京石铁路客运专线石家庄站站房工程地质条件,介绍了钻孔灌注桩后压浆技术在该工程中的应用,分别阐述了后压浆参数、施工工艺及相关技术要求,实践证明钻孔灌注桩采用后压浆工艺后,承载力得到大幅度提高且桩的贯入变形显著减少。
Combining with Shijiazhuang station building engineering geology condition on Jing-Shi passenger special railway line, it introduces the application of cast-in-situ pile post grouting technique in the engineering, respectively expounds the post grouting parameter, construction technology, and relevant technical requirements. Practice shows that ： after applying post grouting technology, the bearing capacity of east-in-situ pile improves greatly and the integration of the pile obviously reduces.
