Churning Piles Technology advantages (1) Since the foundation of the original cement soil mixing soft soil in place, which can maximize the use of the original soil; (2) the impact on the surrounding smaller original building; (3) different according to the nature of soil and engineering design requirements, reasonable choice, more flexible design; easy and convenient soft ground base (4) Construction equipment processing pile driver, management, construction vibration-free, pollution-free, in a dense group of buildings construction, and material sources broad, low prices; (5) after severe soil reinforcement changed little, clayey consolidation lighter body than the undisturbed soil about 10% (but sandy soil solidification body may be 10% higher than the undisturbed soil weight so), substantially lighter than or close to the undisturbed soil soft ground capacity to handle specialized equipment, smaller generating additional settlement; (6) low permeability permeability residential soft ground, although some consolidation in vivo pores, but these not through the pores, the sealed type, and consolidation of the body with a layer of relatively dense crust, its permeability coefficient is very high, with some seepage function; high (7) consolidated strength, high pile capacity; (8) if necessary superstructure, the flexibility to take vertical or horizontal jet or spray jet is inclined so as to form columnar walls, blocks and other forms of reinforcement.
