Defect repairing method for cast-in-place pile
The invention provides a defect repairing method for a cast-in-place pile, and relates to the field of pile foundation repairing. The repairing method comprises the steps that 1, the position and sizeof a pile body defect are determined through a sound wave transmission method; 2, a drill bit is used for continuously coring around the center of the cast-in-place pile to form an annular separationgroove, a concrete core column is broken and hoisted out, and a central vertical shaft is constructed in the cast-in-place pile; 3, the step 2 is repeated, and the depth of the central vertical shaftis increased till the bottom of the central vertical shaft reaches the position below the pile body defect; 4, a constructor descends into a well to chisel away and clean the pile body defect, and drilling slag and concrete chippings on the well wall are flushed away; 5, accumulated water and sediments in the central vertical shaft are discharged, and concrete is poured into the central verticalshaft and vibrated to be compact; and 6, after the strength of the concrete meets the requirement, the cast-in-place pile is rechecked and detected, and it is guaranteed that the quality of the cast-in-place pile meets the standard. Construction personnel can go deep into the cast-in-place pile to conduct visual removal operation, and the repairing effect is better.
本发明提供了一种灌注桩的缺陷修复方法，涉及桩基修复领域。该修复方法包括：步骤一、采用声波透射法确定桩身缺陷的位置和大小；步骤二、利用钻头围绕灌注桩的中心进行连续取芯形成环形分隔槽，折断混凝土芯柱并吊运出去，在灌注桩的内部构造出中心竖井；步骤三、重复步骤二，加大中心竖井的深度，直至中心竖井的底部到达桩身缺陷以下；步骤四、由施工人员下井凿除并清理桩身缺陷，冲洗去除井壁的钻渣和砼屑；步骤五、排出中心竖井中的积水和沉渣，向中心竖井中灌注混凝土并振捣密实；步骤六、待混凝土强度达到要求后，对灌注桩进行复查检测，确保灌注桩的质量符合标准。施工人员可深入灌注桩的内部进行可视化清除操作，修复效果更好。
