The invention discloses a hypernormal vibration blunt replacement construction method. The hypernormal vibration blunt replacement construction method comprises the steps that step one, the soil property and the thickness of a consolidation soil layer are measured, and vibration blunt pile pointsare determined; step two, vibration blunt of the pile points is conducted by using a vibroflot, after the vibration blunt is finished, drainage plate striking points are determined between the pile points, and the drainage plate striking points are evenly arranged in interval modes; after the drainageplate striking points are determined, the SPT value of the soil layer is detected; and when the SPT value is larger than or equal to 60, a drilling machine is used for drilling on the drainage plate striking points, and drainage plates are laid; and step three, pile-loading and prepressingare conducted on the laid drainage plates, the pile-loading height is 5m, and the prepressing is conducted for4 months. According to the hypernormal vibration blunt replacement construction method, operation is simple, construction is convenient, an existing hypernormal vibration blunt device can be replaced, the more excellent construction effect is achieved, the device can be modified in time according tofoundation soil quality conditions of a construction site, and the technical effect of fast, efficient and saving construction can be achieved.
