    • PROBLEM TO BE SOLVED: To provide an apparatus for feeding a soil improving material, which enhances feeding accuracy by suppressing an influence caused by a fluctuation in the bulk density of the soil improving material.
      SOLUTION: This apparatus 14 for feeding the soil improving material, which feeds the soil improving material to sediment, includes: a storage tank 15 for the soil improving material; a feeder 16 for feeding the soil improving material in the storage tank 15 to the sediment; an arch breaker 51 for agitating the soil improving material in the storage tank 15; a load detector for detecting a driving load of the feeder 16; a storage portion which stores a corresponding relationship between the driving load of the feeder 16 and a driving speed of the arch breaker 51; and a computing portion for controlling the driving speed of the arch breaker 51 on the basis of a signal from the load detector and storage information of the storage portion. A speed command value for the arch breaker 51 is increased in accordance with a decrease in the driving load of the feeder 16, and decreased with an increase in the driving load of the feeder 16.
