    摘要： A novel method to construct a reinforcing block in an embankment is provided, wherein a core rod to which a protrusion is molded on the tip, is preset inside a hollow rotating shaft with drilling and agitating blades affixed around its circumference, but with the protrusion on the core rod exposed at the front of the shaft. This drilling and agitating shaft rotates and bores into the earth while simultaneously mixing the soil so agitated with a fixing agent; then at a specified depth, the rotating shaft is withdrawn leaving the core rod to remain anchored in the soil while the fixing agent continues to discharge from the end of the hollow rod; and when the hollow rod is completely removed, a reinforcing block is intact within the soil and the tail end of the core rod exposed on the surface of the banking is directly or indirectly affixed to this surface. Alternatively a core rod with no protrusion can be inserted into the hollow rotating shaft which is first drilled into the embankment, such that the nose end of the said core rod is anchored into unagitated soil. In either case the reinforcing block so formed is comprised of an outer concentric tube of agitated soil mixed with a fixing agent molded around an inner concentric tube of reinforcing fixing agent molded around a core rod, and wherein the nose tip of the core penetrates into the unagitated soil beyond the end of the concentric reinforcing layers.
