Quick pile splicing method for broken rotary excavating cast-in-situ bored pile
The invention discloses a quick pile splicing method for a broken rotary excavating cast-in-situ bored pile. The quick pile splicing method comprises the following steps that step 1, when the situation that the pile is broken due to pipe blockage and other reasons during cast-in-situ pile concrete pouring is found, a guide pipe is pulled out and cleaned, where pipe blockage refers to the guide pipe poured by concrete; step 2, the depth of a breaking position of the pile is measured; step 3, the cleaned guide pipe is placed at a position 500-1000 mm away from the broken pile, concrete is poured, slurry in the guide pipe is removed, and a mixture at the joint of the concrete and the slurry is extruded out of an original concrete pouring face; and step 4, the guide pipe is inserted into a position 4-5 m below the mixture of the concrete and the slurry. The method is scientific, reasonable and convenient in construction; and pile splicing is simple and comprehensive, pile splicing is carried out by using the rescue method after actual pile breaking, and after ultrasonic detection, the integrity of a pile body meets the requirements of related specifications.
本发明公开了一种旋挖钻孔灌注桩断桩快速接桩方法，包括如下步骤：步骤一，在发现灌注桩混凝土浇筑时出现堵管等原因而致断桩，拔出导管并进行清洗；堵管是指混凝土浇筑的导管；步骤二：进行断桩位置深度测量；步骤三：将清洗完成的导管放入离断桩深度500mm‑1000mm处浇筑混凝土，排除导管内的泥浆，并将混凝土与泥浆交接处混合物挤出原混凝土浇筑面；步骤四：将导管插入混凝土与泥浆混合物以下4‑5m。本方法科学合理，施工便捷；并接桩简单且全面，经过实际断桩后用此“抢救”方法接桩，并经超声波检测后，其桩身完整性满足相关规范要求。
