一种填海区复杂地质条件钻孔灌注桩多机联合施工方法
摘要：
本发明公开了建筑施工领域中的一种填海区复杂地质条件钻孔灌注桩多机联合施工方法，包括场地准备、桩位放样、埋设护筒、旋挖钻机就位、旋挖钻进、终孔、成孔检测、钢筋笼的制作与安装、浇筑混凝土等步骤。本发明适用于填海区复杂地质条件下的市政、建筑和城市轨道交通等工程的桩基础施工，采用多种钻机联合施工成孔，技术先进、适用性强，经济、高效，并取得良好的社会经济效应。
摘要（英）：

The invention discloses a reclamation area complicated geological condition cast-in-situ bored pile multi-machine combined construction method in the field of construction. The method comprises the steps of field preparation, pile position lofting, embedment of protection cylinders, placement of a rotary drilling rig, rotary drilling, hole formation, hole detection, manufacturing and installationof reinforcement cages, casting of concrete and the like. The reclamation area complicated geological condition cast-in-situ bored pile multi-machine combined construction method is suitable for pilefoundation construction of such engineering as municipal administration, construction and urban rail traffic under reclamation area complicated geological conditions, adopts multiple drilling machinesfor combined construction to form holes, and achieves advanced technology, high applicability, economy, high efficiency and excellent social and economical effects.
