Dynamic compaction pretreatment pile-forming construction method
The invention belongs to the field of buildings, and particularly relates to a dynamic compaction pretreatment pile-forming construction method. The method comprises the following steps: 1, measuring support pile axes and tamping points; 2, continuous point compaction is conducted; the dynamic compaction point position is continuously and repeatedly subjected to point compaction; 3, clay is backfilled; clay is filled in a ramming pit formed by point ramming; 4, single-time point compaction is conducted; carrying out point compaction again at the dynamic compaction point filled with the clay; 5, measuring the depth; a ramming pit formed by single point ramming is measured, whether the depth of the ramming pit meets the requirement or not is measured, the sixth step is executed if the depth meets the requirement, and the third step is executed if the depth does not meet the requirement; sixthly, foundation pit supporting piles are constructed; and the rammed pit is leveled and compacted, and foundation pit supporting pile construction is conducted. By the adoption of the construction method, the original ultra-thick loose rock-filled layer is compacted, the pore-forming thickness of the rock-filled layer of the support pile is compressed and reduced, the phenomena of hole collapse and slurry leakage are not found any more in the rotary excavating drilling process, the pore-forming time is greatly shortened, and the drilling efficiency is remarkably improved.
本发明属于建筑领域，特别涉及到了一种强夯预处理成桩施工方法，该施工方法包括以下步骤；步骤1：测放支护桩轴线、夯点；步骤2：连续点夯；对强夯夯点位置进行连续多次点夯；步骤3：回填黏土；在点夯形成的夯坑填入黏土；步骤4：单次点夯；在填入黏土后的强夯夯点处进行再次点夯；步骤5：测量深度；在单次点夯形成的夯坑进行测量，测量夯坑的深度是否满足需求，满足进入步骤6，不满足则进入步骤3；步骤6：基坑支护桩施工；对夯坑进行平整、压实，并进行基坑支护桩施工。采用本施工方法，原超厚松散填石层被夯击密实，支护桩填石层成孔厚度被压缩减小，且旋挖钻进过程中不再发现塌孔、漏浆现象，成孔时间大大缩短，显著提升钻进效率。
