Method for treating high-strength replacement pier composite ground foundation and high-strength replacement pier
The invention relates to a method for treating a high-strength replacement pier composite ground foundation. The method comprises the following steps of a. performing hole forming construction on a raw soil layer to form pier holes; b. filling the pier holes with coarse aggregate, tamping and extruding the coarse aggregate to the bottom part of each hole, synchronously performing filling and tamping, and enabling the tamped coarse aggregate to form a step-shaped coarse aggregate supporting layer; c. filling the pier holes with dry concrete replacement material above the coarse aggregate supporting layer; d. tamping the dry concrete replacement material to form a dry concrete replacement section. The method has the advantage that the coarse aggregate and the dry concrete are respectively used as replacement materials, and the simultaneous tamping and filling method is adopted, so a finally formed pier body has large compactness and high compressive strength, the higher bearing capacity is obtained, and the defect of lower bearing capacity of an original pouring pier completely made of mixed concrete is overcome. The invention also provides the high-strength replacement pier.
