后注浆桩技术应用研究
|
摘要
结合工程实例,通过对泥浆护壁钻孔灌注桩采用后注浆技术,明显增强单桩竖向承载力事实的分析,得出了以下结论:把后注浆技术引用到桩基工程中,采取对桩端及桩侧实施压力注浆措施,解决桩底沉渣和桩侧泥膜影响桩基承载力的问题,从而达到增强桩基承载力、缩短工期、减少工程造价的目的。
This paper through the bored piles of mud wall grouting technology used after processing,single vertical bearing capacity significantly improved with more examples,draws the following conclusions: the technology used to pile grouting works,to take on the piles and piles-pressure side of the grouting measures to address the impact of pile bearing capacity of the main factors(at the end of sediment piles and piles side mud film),to deliver the pile bearing capacity,reduce the period to reduce the project cost Purpose,and have achieved good social and economic benefits.
