Method for treating sludge backfill foundation through dynamic compaction replacement treatment
The invention relates to the technical field of foundation treatment, in particular to a dynamic compaction replacement treatment sludge backfill foundation treatment method, by excavating a first sludge outlet and a second sludge outlet respectively during two times of point compaction replacement construction, sludge can be discharged from the first sludge outlet and the second sludge outlet, the internal pressure of a site is reduced, and the construction efficiency is improved. By gradually increasing the replacement energy level, carrying out point compaction replacement twice, then carrying out full compaction and rolling for six times after compaction, the construction safety is improved, a muddy soil layer is penetrated, the replacement depth reaches 8 m, the feeding depth of a replacement material is increased, soft soil is reinforced and compacted, a replacement pier body is formed, the integrity of a foundation is improved, and the construction period is shortened. Therefore, the bearing capacity and the compression modulus of the foundation are improved, the purpose of foundation treatment is achieved, and the method is low in cost and short in period.
本发明涉及地基处理技术领域，尤其涉及一种强夯置换处理淤泥回填地基处理方法，通过在两遍点夯置换施工时分别开挖第一出泥口和第二出泥口，淤泥能够从第一出泥口和第二出泥口中排出，减小了场地内部压力，通过逐步增加置换能级，进行两遍点夯置换之后再进行满夯，夯后碾压6遍，提高了施工安全性，穿透淤泥质土层，使得置换深度达到8m，提高了置换材料的送入深度，使软弱土得到加固密实，形成置换墩体增加地基整体性，从而提高地基的承载力和压缩模量，达到地基处理的目的，此方法成本低、周期短。
