PROBLEM TO BE SOLVED: To provide a method of injecting a hardener into target ground to reinforce the ground, wherein the method achieves uniform injection of the hardener into minute gaps in the ground. SOLUTION: There is provided a hardener vibrating injection method which has a step of injecting the hardener in a slurry state into a hardener injection space secured in the target ground beforehand, and a step of infiltrating the hardener into the target ground around the space by generating vibration in the injected hardener. The method further has a step of forming the hardener injection space prior to the step of injecting the hardener. The step of injecting the hardener and the step of generating vibration may be simultaneously carried out. The vibration has a frequency in the range of 10 to 20 kHz or falls in an ultrasonic zone. The target ground includes a roadbed of a road, a subgrade of a road, and ground under a road, and the hardener injection space is located on a side surface of the road. COPYRIGHT: (C)2008,JPO&INPIT
