石家庄地区灌注桩后注浆工艺工程应用

Method of Cast-in-place Pile Post Grouting and Application Shijiazhuang

利用工程实例介绍了钻孔灌注桩后．注浆工艺在石家庄地区的应用。通过对后注浆的桩体进行静载荷试验．并对载荷试验结果进行了汇总分析。经验证．注浆后的桩基承载力有明显的提高．多道注浆管的设置方式提供了较高的施工可靠度，具有明显的经济效益和实际应用价值。

This paper describes the use of post grouting process in Shijiazhuang combine practical projects. By the static locding experimentation of post grouting pile, and analyzing the results of the test. It is proved that. the grouting pile bearing capacity has been significantly improved, Setting mode multi channel grouting pipe construction provides higher reliability. It is obvious to produce the economic and practical value.
