Construction method for compaction and pre-feeding replacement material dynamic compaction replacement of vibration immersed tube pile machine
The invention discloses a construction method for compaction and pre-feeding replacement material dynamic compaction replacement of a vibration immersed tube pile machine, and belongs to the field of dynamic compaction replacement. The construction method for compaction and pre-feeding replacement material dynamic compaction replacement of the vibration immersed tube pile machine comprises the following steps of S1, compaction and pre-feeding construction of the vibration immersed tube pile machine; S2, column hammer replacement point tamping construction; S3, point tamping construction of a common hammer; and S4, full compaction construction. According to the construction method for compaction and pre-feeding replacement material dynamic compaction replacement of the vibration immersed tube pile machine, point compaction and compaction and enlargement of a replacement material pier body are carried out through the column hammer, repeated compaction and repeated feeding are not needed, the construction efficiency is improved to be one to three times of the original construction efficiency, and the method is suitable for foundation treatment projects such as low and high saturation silty (viscous) soil, flow plastic-soft plastic cohesive soil, loose sandy soil, plain filling soil, miscellaneous filling soil and the like.
本发明公开了一种振动沉管桩机挤密预投置换料强夯置换的施工方法，属于强夯置换领域，振动沉管桩机挤密预投置换料强夯置换的施工方法包括如下步骤：S1、振动沉管桩机挤密预投料施工；S2、柱锤置换点夯施工；S3、普通锤点夯施工；S4、满夯施工。本发明公开的一种振动沉管桩机挤密预投置换料强夯置换的施工方法，通过柱锤进行点夯夯实及扩大置换料墩体，不需反复夯击、反复投料，使施工效率提高至原来一至三倍，适用于处理低、高饱和度的粉(粘)土、流塑～软塑的黏性土、松散性砂土、素填土、杂填土等地基处理工程。
