Cast-in-situ bored pile foundation construction method
The invention provides a cast-in-situ bored pile foundation construction method. The cast-in-situ bored pile foundation construction method comprises the steps that the ground near a construction site is leveled, and the pile point position is determined; a pile casing is buried around the pile point position; a drilling machine is adopted for conducting drilling operation on the pile point position; a hole drilled by a drill hole is checked and cleaned; a reinforcement cage is hoisted into the hole; and a guide pipe is adopted for pouring concrete into the hole; and the guide pipe is dismounted, and nondestructive testing is conducted on a pile foundation. The cast-in-situ bored pile foundation construction method has the beneficial effects that the construction scheme is simple, and the construction difficulty is low.
本发明提供一种钻孔灌注桩基础施工方法，包括：将施工场地附近地面找平，确定桩点位置；在桩点位置周围埋设护筒；采用钻机对桩点位置进行钻孔作业；对钻孔钻出的孔洞进行检查和清理；将钢筋笼吊入孔洞内；采用导管向孔洞内灌注混凝土；拆除导管，并对桩基进行无损检测。该钻孔灌注桩基础施工方法具有施工方案简单，施工难度小的优点。
