Churning Pile advantage reinforcement technology (1) Since the cement foundation soft soil with original soil in situ mixing jet grouting pile, which can maximize the use of the original soil; (2) the impact on the surrounding smaller original building; (3) in accordance with the nature and engineering requirements of different soil Churning Pile single-tube equipment, reasonable selection, design more flexible; (4) Construction equipment is simple, easy to manage, no vibration during the construction of the new walking Churning Pile machine manufacturers, non-polluting, can be carried out in dense buildings in construction, and material sources broad, low prices; severe change after reinforcement (5) is not soil, about 10% of the body than the undisturbed soil clayey consolidation light (but sandy soil may be higher than the undisturbed soil solidification body weight of 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, 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, 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. Jet Grouting Technology Overview high pressure jet grouting method is generally used after drilling rig drilled to the design depth, means Churning Pile background with high-pressure injection pump mud pump occurs through special nozzles are mounted in the drill-side, to surrounding soil chemical grout injection (commonly used cement slurry), while the drill pipe to a certain speed slowly improved, high-pressure jet destroyed the structure of soil near and forces with chemical grout mix in the ground hardened into a uniform diameter cylinder. Engineering can also be adjusted according to increase speed, injection pressure changes, or change the diameter of the nozzle, thereby changing the flow, so that the desired consolidation of the body to become designed shape.
