  • Patent number: 5904447
    Abstract: A drive device for injecting different types of fluids, chemicals and slurries into a subsurface for soil stabilization and removing fluids from the subsurface prior to treating a soil. The device is designed to be self advancing into the soil. When the driving of the device in the ground surface is completed, the device can be removed or it can be left in place for forming an anchor or load carrying pier. The device includes a plurality of external and internal hollow pipe sections. The pipe sections are joined together with couplings. Each coupling includes perforations therein and helices around the exterior surface of the coupling. The helices are used for driving the pipe sections into the ground. The perforations in each coupling are used for introducing fluids under pressure into the soil or for extracting fluids from the subsurface.
