More Information
Summary:The invention belongs to the technical field of soft soil foundation treatment methods and particularly relates to a novel cement oil composite mixing pile and a pile formation method thereof. The mixing pile comprises the variable-section cement soil mixing pile and a quadrangular frustum pyramid-shaped reinforced concrete core pile, wherein the core pile is inserted into the mixing pile along the center of the section of the mixing pile and in close fit with the mixing pile. The novel cement soil composite mixing pile is manufactured by well using existing equipment and materials through changing material structure, construction process steps, the section of a pile body and the force transfer way and has the advantages of good pile formation quality, high strength of cement soil, high pile foundation bearing capacity and low cost.
