摘要
干作业螺旋钻孔钢筋混凝土灌注桩适用于地下水位较低、在成孔深度内无地下水的土质,成孔时无需采取护壁措施即可直接取土成孔,因此应用广泛。根据工程经验,针对该桩常见的质量问题,对成因进行剖析,并提出相应的处理方法及防治措施,以达到提高施工质量的目的。
Reinforced concrete bored pile with dry work spiral drilling is suitable for the soil of low underground water level and no underground water in pore-forming depth.This method doesn't apply wall protection for pore-forming,and has extensive application.Based on practical engineering,the quality problems causes are analyzed,and treatment and prevention methods are put forward to improve construction quality.
