某中原地区地基处理工程后压浆灌注桩施工实例

The construction example of post grouting bored pile of foundation treatment engineering in a central plains area

结合中原地区地基处理工程实例,详细介绍了后压浆灌注桩的施工工艺流程、特点和施工过程控制要点,并通过实际应用,指出采用钻孔灌注桩后压浆技术可有效提高单桩承载力、减少沉降量,具有较高的技术、经济效益。

Combining with the engineering example of foundation treatment in central plains area, this paper introduced in detail the construction process, characteristics and construction process control key points of post grouting bored pile, and through the practical application, using post grouting technology of bored pile could improve effectively the bearing capacity of single pile, reduced the settlement, had high technology, eco- nomic benefit.
