    • 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.
    • 本发明涉及一种用于在软土地层中构造管桩基础的装置。 在使用中,设备从起重机或地上的井架或岸上的工作驳船悬挂在软土中。 用于使软土体稳定的装置包括:机箱保持驱动装置;连接到所述驱动装置的驱动轴装置;搅拌筒装置,用于搅拌设置在所述驱动轴装置下端的软土;所述搅拌筒装置 具有多个搅拌叶片,以及用于将硬化剂注入软土中以形成固化管状桩的化学硬化剂给料系统,所述化学硬化剂给料系统包括旋转接头,输送管和注射喷嘴。 在通过搅拌和混合土壤与固化剂的原位构造管状固体桩的过程中,装置可以向上和向下移动,为土层提供高承载能力。
