[0001] The utility model relates to the technical field of powder injection piles, in particular to a feeding device for powder injection piles. Background Art

[0002] Powder injection piles are a form of deep mixing method for strengthening foundations, also known as reinforced soil piles. The deep mixing method is a novel method for strengthening saturated soft clay foundations. It uses cement, lime and other materials as the main agent of the curing agent, and uses a special mixing machine to forcefully mix the soft soil and curing agent (in slurry and powder form) on site. The series of physical and chemical reactions between the curing agent and the soft soil are used to harden the soft soil into a high-quality foundation with integrity, water stability and a certain strength.

[0003] The existing feeding devices for powder injection piles still have some defects. Most of them have relatively single functions and do not have the function of crushing lime. Lime will produce a certain amount of moisture during storage, which will cause the lime to solidify into blocks, which is easy to cause blockage during the feeding process, resulting in low feeding efficiency. For this reason, we propose a feeding device for powder injection piles.
