Single-row piles and jet grouting seepage curtain integral connection of good quality Jet system are connected by a plurality of row piles Churning Pile made of soft foundation treatment, seepage curtain is also given by a number of spray, spray or jet grouting of swing body composition. They are not simultaneously sprayed into, but there is no problem of old and new poor connection. Good stability seepage curtain Mu. Because the high-pressure jet of tremendous energy, as long as the new and old physical consolidation is connected to the new consolidated body jet stream old consolidation can impact the surface is very clean, new and old after hardening solidification body as a single entity. 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, a reasonable selection, design more flexible; simple soft base (4) Construction equipment handling ways in which to facilitate the management, no vibration during construction, pollution sets of soft-processing equipment company, may carried out in dense buildings in construction, and material sources broad, low prices; severe change after reinforcement (5) is not soil, clay soil consolidation lighter body than the undisturbed soil about 10% (but sandy soil solidification body may weight than the undisturbed soil about 10%), substantially lighter than the undisturbed soil or near capacity, the smaller generate additional settlement; (6) low permeability permeability, porosity, although some consolidation in vivo, but not through these pores for sealed soft foundation treatment sealing curtain construction 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, pile capacity high; (8) the upper structure required can be flexibly take vertical or horizontal spray jet or tilt injection, make it a pillar, wall, blocks and other forms of reinforcement.
