Abstract
PURPOSE: To smoothly supply powder particle material underground by expanding diameter of film material consisting of elastic sealing material fitted to inside of tubular pipe that is penetrated into earth, by means of internal and external pressure difference.
CONSTITUTION: Pressure Px inside tubular pipe 1 pnentrated into earth and pressure Py in the space of inside film material 5 made of elastic sealing material are set to atomospheric pressure at first. Under this condition, powder particle material 14 is thrown into pipe 1 through hopper 12, while change-over valve 9 is operated to supply the compressed air inside receiver tank 8 into pipe 1. As the result, air valve 1 is closed due to the compressed air injection flow, pressure Px inside pipe 1 is increased, a pressure is loaded against material 14 in the direction of arrow and at the same time, a pressure is loaded against film material 5 toward outside direction. Furthermore, film material 5 is pressed toward outside direction, and by expanding the diameter, an aperture is created instantaneously between material 14 and film material 5. Nextly, by such operation and the pulling off operation of pipe 1, material 14 can be dropped easily to supply material 14 to the hole underground. Material 14 includes the materials for the modification of foundation such as sand, lime, mineral and so on.
