Summary:The invention provides a pile forming method for a sinking pipe cast-in-place composite pile. The pile forming method comprises the following steps: sinking a pile pipe to form a hole in a manner of striking inwards or statically pressing, pumping a flow-state cementing material, and then inserting a precast pile to form the pile. The pile has high bearing forces at the end and the side thereof and a high penetrating capacity, and is simple to operate, free from pipe blockage, high in working efficiency, material-saving, low in requirements on a pipe pulling capacity of a pile machine, and good in technical, economic and social benefits. 本发明提供了沉管压灌复合桩的成桩方法，是用内击或静压方式下沉桩管成孔、泵送流态胶结料后插入预制桩成桩，其桩端、桩侧的承载力均较高、穿透能力较强、操作较简单、不堵管、工效较高、节约材料、对桩机的拔管能力要求较低，具有较好的技术、经济和社会效益。
