| Abstract: | Based on the field case, long spiral super-fluid concrete grouting pile was introduced on construction technology, application scope, technical features and the estimation of vertical beating capacity of a single pile. Comparing with conventional bored-grouting pile, this technology has advantages of simple operation, environmental protection, rapid construction speed and good pile quality with 50% bearing capacity increased, more than 40% concrete amount reduced and 40% construction cost saved. |
