Bidirectional mixing pile construction method for deep sludge
The invention relates to the technical field of civil engineering, in particular to a bidirectional mixing pile construction method, in particular to a bidirectional mixing pile construction method for deep sludge. The bidirectional mixing pile construction method for the deep sludge comprises the following steps that S1, surveying and setting out are carried out, and a pile position is set out; S2, construction preparation is carried out; S3, a pile is tested, and various feasibility indexes of the bidirectional mixing pile are determined; if the original construction process and the cement-soil mixing ratio meet the requirements, pile testing is completed, and if the original construction process and the cement-soil mixing ratio cannot meet the requirements, construction process parameters and the cement-soil mixing ratio are adjusted until the requirements are met; and S4, the pile is formed, a deep mixer is adopted for bidirectional mixing pile construction, in the construction process, the pile length, the pile diameter, the cement doping amount and the pile body strength after pile forming are detected, immediate adjustment is carried out according to the deviation, the perpendicularity of a pile body is guaranteed, and then the mixing uniformity and the pile body strength are guaranteed.
本发明涉及土木工程技术领域，具体涉及一种双向搅拌桩施工工法，特别是一种深层淤泥双向搅拌桩施工工法，包括如下步骤，S1，测量放样，定出桩位；S2，施工准备；S3，试桩，确定双向搅拌桩各项可行性指标；若原定施工工艺和水泥土配合比满足要求时，试桩完毕，若不能满足要求，调整施工工艺参数和水泥土配合比，直至达到要求；S4，成桩，采用深层搅拌机进行双向搅拌桩施工，在施工过程中，对桩长、桩径，水泥掺入量及成桩后的桩体强度进行检测，并根据出现的偏差进行即时调整，保证了桩体的垂直度、进而保证了搅拌均匀度和桩体强度。
