Cement-soil mixing pile construction system and method and cement-soil mixing pile
The invention discloses a cement-soil mixing pile construction system and method and a cement-soil mixing pile. The upper end of a stirring paddle is hinged to an avoiding groove of a drill bit, so that when a drill rod rotates downwards, the outwards-swinging stirring paddle can stir a soil body and disturb the soil body; after the drill rod drives the spiral pipe to rotate and drill to a preset depth and the connection relation between the spiral pipe and the drill rod is released, the drill rod is driven to rotate and move upwards at a preset speed and the slurry is driven to be injected into the soil body through the slurry outlet of the drill bit, and meanwhile, the stirring paddle overcomes the elastic force to swing into the avoiding groove under the action of the spiral pipe; therefore, the spiral pipe can rotate upwards relative to the spiral pipe until leaving the soil body. And after the drill rod leaves the soil body and completes grouting, the electric heating body in the spiral pipe is heated, the unsolidified cement mixing pile and the surrounding soil body are heated, and the water content of the mixing pile is reduced to a preset range, so that the slurry hydration in the pile forming process of the cement mixing pile is more thorough, the pile forming strength is improved, and the construction period is shortened. And the reinforcing effect of the soft soil foundation is improved.
本发明公开了一种水泥土搅拌桩施工系统、方法及水泥土搅拌桩，将搅拌桨的上端铰接于钻头的避让槽中以使钻杆旋转下行时，外摆后的搅拌桨能够搅拌土体并挠动土体，而当钻杆带动螺旋管旋转下钻到预定深度并解除螺旋管与钻杆的连接关系后，驱使钻杆以预定速度旋转上行并驱使浆液经钻头的出浆口注入土体的同时，搅拌桨在螺旋管作用下克服弹性力往避让槽内部摆动，从而能相对螺旋管旋转上行，直至离开土体。而当钻杆离开土体并完成注浆后，则使螺旋管内的电热体发热，对未凝固的水泥搅拌桩及周围土体进行加热，并将搅拌桩的含水率降低至预定范围，从而使水泥搅拌桩成桩过程浆液水化更为彻底，进而提高成桩强度，提高软土地基的加固效果。
