Abstract

PURPOSE: To dispense with a pressure resisting hopper and simplify the operation in such a way that with choking between the hopper and Venturi, after an injection pipe has been scavenged with transferring gas, choking is released, improver particle is fed into the foundation to be improved by means of Venturi negative pressure.
CONSTITUTION: With a controller 38 perated, and a closing valve 34 closed, after high pressure air has been fed from an air compressor 32 through a spouting pipe 31, it is spouted through a feeding pipe 28, a hose 29, and a swiveling joint out of a jet stirrer nozzle unshown in the figure which is at boring of the foundation 1. Thus, ejector negative pressure is formed at a Venturi part 30. With this negative pressure detected by a pressure switch 41, input is given to the controller 38, and when it becomes the determined negative pressure, at the same time as it opens the closing valve 34, drives a motor 27, and drops particle 24 into a feeding port 20. The particle is sucked by the negative pressure and fed thereby. This structrue facilitates to make a hooper to be a constant pressure type, to perform flow type feeding, and to simplify the operation.
