摘要
钻孔灌注桩是桩基础的重要桩型之一,由于桩侧泥皮及桩底沉渣的客观存在,其承载力的发挥和提高均受到限制。后注浆技术可有效提高钻孔灌注桩的竖向承载力并减小基础沉降量。灌注桩后注浆技术在工程应用时要合理确定承载力、注浆工艺参数等。通过工程实例,分析灌注桩后注浆技术应用的可行性和经济性。
Bored pile is an important type in pile foundation.Due to the existence of mud skin on the side of pile and sediment at the bottom of pile,the exertion and improvement of its bearing capacity are limited.Post-grouting technology can effectively improve the bearing capacity of bored pile and reduce the foundation settlement.When the post-grouting technology of bored pile is applied in engineering,the bearing capacity and grouting process parameters should be reasonably determined.Analyzed the feasibility and economy of the application of post-grouting technology for bored pile by citing the examples.
