On July 8, the invention patent "Method for Determining the Uniformity of Cement-Soil Mixing Pile Body" applied for by MCC Group Wuhan Survey and Research Institute was authorized by the China National Intellectual Property Administration.
　　The "Method for Determining the Uniformity of Cement-Soil Mixing Pile Body" invented by MCC Wukan is a quantitative determination method that utilizes the strength and water stability characteristics of cement-soil. It defines the quantitative indicator "pile body uniformity coefficient M" as the product of two measurable indicators, "quality coefficient C1" and "strength coefficient C2." These coefficients can comprehensively reflect various factors affecting the uniformity of cement-soil mixing piles and can directly determine whether the mixing pile meets construction technical requirements. This method is objective and convenient, highly operable, and has a unified evaluation standard, overcoming the arbitrariness of manual visual judgment results in existing specifications. In addition, this method can directly use samples after unconfined compressive strength testing without the need to take additional samples, saving substantial testing costs.
