ABSTRACT:
In a method of stabilizing, by means of a stabilizing machine adapted to inject a stabilizing agent into the ground, a ground surface whose bearing capacity is so low that it is unable to support the stabilizing machine or can only support said machine with difficulty, there is used a stabilizing unit supported by the drive or transport unit of said machine in front thereof as seen in the drive direction. The stabilizing unit has a width which exceeds the width of said drive or transport unit. The stabilizing agent is introduced into the ground to a depth of such magnitude, and the machine is driven at such a speed that the ground is sufficiently stabilized by said stabilizing agent introduced thereinto to support the whole of the stabilizing machine. The stabilizing unit may be partially supported by lifting and/or carrying arms of the drive unit and partially by separate ground-engaging tracks or wheels arranged between said unit and said drive unit.
The means for introducing stabilizing agent into the ground may be provided with support surfaces arranged to engage the surface of the ground so as to assist in supporting the weight of said unit.
The invention also concerns a stabilizing unit for carrying out the method and having means for connecting it to a tractor or a similar vehicle so that it is supported in front thereof.
