By way of contrast tests for on the new type of ESC mixing piles body with the soil-cement mixing piles body

the mechanism of ESC solidified soil is expounded; and that these mixing piles have higher side friction is proved. Meanwhile

that substituting the ESC solidifying agent for cement can obviously increase the strength of solidified soil in the mixing piles is proved. Therefore this method has naturally solved the following problem

that is

the single use of cement can’t allow full play to the side friction because of low strength of the bodies of mixing pile and low bearing capacity of the single pile.
