Abstract: PURPOSE: To enable to effect a work of continuous hardening treatment for a soft and weak ground in a narrow place with a small number of man-power by a method wherein a device for hardening treatment for the soft and weak ground is attached at a tip end of an arm rod for a self-propelled vehicle such as a crane car or  the like and chemical liquid is mixed and stirred.  
     CONSTITUTION: A heavy vehicle 1 such as a back-hoe, a crane or the like is transported to a site. A hardening agent is sent into a hole 6 of a shaft 7 by a pressure through a hose 10 for sending the agent by the pressure and is injected into a soft and weak ground continuously from nozzles 9 of stirring wings. At the same time, arm rods 2, 3 are lowered by a prime moving machine while the shaft 7 is being rotated. The stirring wings 8 mix, lower and invade the hardening agent into sludge during stirring it. When a processing depth is arrived at a predetermined depth, the arm rods 2, 3 are elevated and the shaft 7 is withdrawn. In a similar manner, the vehicle is transported to a next site and effects a work of hardening treatment for the sludge by stirring and mixing the hardening agent with the sludge.

After the rolled bodies and the spacers have been set on the center core, elastic bodies 7 are externally fitted to the nearby positions of both ends of the center core 5. It is preferable that the elastic body 7 is low in the moisture-permeability and a rubber ring 9 ingrows in the elastic body 7 when fixing the moisture-proof film 8 with the rubber ring 9. That is, the hermetical sealability is improved by charging the elastic bodies 7 between creases caused when winding the moisture proof film 8 on the elastic body 7.
