A nonbleed concrete consolidation grouting method is provided to secure the bearing capacity of the soft ground and to form a high consolidation of an underground hollow section and a lower foundation file of a structure by consolidation grouting concrete mixed with cement, aggregate, sand or soil, an admixture and water to the target ground under high pressure. The invention relates to a method for consolidation grouting concrete mixed with cement, aggregate, sand or soil, an admixture and water to the target ground using a high pressure pump and a concrete pump car comprises the steps of selecting a site for performing injection work effectively and installing an arrangement plant within the range not to influence the injection work, placing concrete material to the arrangement plant by placing aggregate, sand or soil, cement and water in order and mixing, perforating an injection hole and installing an injection pipe to the perforated injection hole, and injecting the concrete material mixed with aggregate, sand or soil, an admixture and water, and testing for quality control.
