摘　　要：近年来,传统灌注桩破桩头采用的直接破除的施工方法因其效率低下、造价高及对桩头钢筋保护不足等缺陷,已逐渐被施工现场所淘汰。由此,本研究提出一种桩头钢筋预先套EPE珍珠棉泡沫空心软管隔离混凝土结合双环切法高效无损破除灌注桩头的创新施工思路,并试验应用于实际现场桩基工程的施工,并取得好的成效。In recent years,the traditional construction method of directly breaking the pile head of drilled cast-in-place piles has gradually been phased out on construction sites due to its low efficiency,high cost,and insufficient protection of steel bars at the pile head.Therefore,this paper puts forward an innovative construction idea,that is,the EPE pearl cotton foam hollow hose is pre sleeved on the pile head reinforcement to isolate the concrete,and the double ring cutting method is used to effectively damage the cast-in-place pile head.The test is applied to the construction of the actual pile foundation project,and has achieved good results.
