Hole cleaning equipment and hole cleaning method after hole collapse of lime-soil compaction pile
The invention discloses hole cleaning equipment and a hole cleaning method after hole collapse of a lime-soil compaction pile, and relates to the technical field of construction of special roadbed treatment lime-soil compaction piles in collapsible loess areas. Comprising the following steps that firstly, the plane position of the lime-soil compaction pile is determined and marked; secondly, drilling is conducted through lime-soil compaction pile hole forming equipment, and whether the hole depth meets the drawing design requirement or not is detected after hole forming; and thirdly, the collapsed pile hole is cleaned, hole cleaning equipment is slowly placed in the hole, and secondary hole collapse caused by disturbance of a hole wall soil body is avoided. And fourthly, after the soil body in the collapsed hole is cleaned up, 10% lime soil backfilling construction is conducted in the hole. The problem that the hole forming quality is poor due to hole collapse of the lime-soil compaction pile can be solved, hole cleaning equipment is adopted for hole cleaning, operation is easy and convenient, hole cleaning can be conducted manually, the construction time is greatly shortened, the hole forming quality is improved, and high economic applicability is achieved.
本发明为一种灰土挤密桩塌孔后的清孔设备及清孔方法，涉及湿陷性黄土地区特殊路基处理灰土挤密桩施工技术领域。包括如下步骤：第一步确定灰土挤密桩平面位置并做出标记；第二步用灰土挤密桩成孔设备进行打孔，成孔后检测孔深是否符合图纸设计要求；第三步对塌孔的桩孔进行清孔，将清孔设备缓慢放入孔内，避免扰动孔壁土体造成二次塌孔。第四步塌孔内土体清理干净后，进行孔内10％灰土回填施工。本发明可以解决灰土挤密桩塌孔造成成孔质量差的难题，采用清孔设备进行清孔，操作简便，人工即可进行清孔，大大缩短了施工时间，提高了成孔质量，具有很强的经济适用性。
