Device for constructing a foundation in soft soil formations

Abstract

The present invention relates to a device for constructing a tubular pile foundation in soft soil formations. Where in use, the device is suspended into the soft soil from a crane or a derrick on the earth or a working barge off shore. The device for stabilizing a body of the soft soil comprises a machine box holding driving means, driving shaft means connected to said drive means, agitating barrel means for stirring the soft soil disposed at the lower end of said driving shaft means, said agitating barrel means having a plurality of agitating blades, and a chemical hardener feeder system for injecting the hardener into the soft soil to form solidified tubular piles, said chemical hardener feeder system including swivel joints, delivery pipes and injection nozzles. The device can be moved upward and downward in course of constructing tubular solid piles in situ by agitating and mixing the soil with the hardener to provide the high bearing capacity to the soil layers.
