Abstract: The concept of ASE pile is put forward based on the engineering properties of super soft soil filled with dredger fill, which refers to the construction technology of sinking pipe into composite material and in-situ expanding mixing. Considering the principle of providing basic strength and skeleton support for super soft soil with solidified fine material and skeleton coarse material, and referring the construction technology of mixing pile and CFG pile, a special double tower construction equipment is made and a new construction technology is formed. The field test shows that the ideal pile can be formed when the mixture of solidified fine material and skeleton coarse material is appropriate. The quality of pile forming is mainly affected by the solidified fine material, and the effect of skeleton coarse material depends on the solidified fine material of certain mix proportion foundation. It is feasible to feed the immersed tube first and then expand the diameter for stirring. The annular blade can achieve the effect of expanding the diameter, and the effect of two-way expanding stirring is better than that of one-way expanding stirring. The design and calculation method of ASE pile need to be further studied, which can refer to the relevant theories of CFG and mixing pile.
