Japanese Patent JP3151637

B2

PURPOSE: To improve the workability by filling plural filling liquids, of which solidification time is different from each other, from plural fill-in ports of different positions in the axial direction of a filling pipe, simultaneously, and changing each flow quantity of the main agent and the reaction agent to change the mixture ratio.
CONSTITUTION: Plural fill-in ports 3 are provided at different positions in the axial direction of a filling pipe X, which consists of an outer tube 1 and an inner tube 2, and the outer tube 1 and the inner tube 2 are communicated with each other through a discharge port. At least two of the fill-in ports 3 are formed so as to have different flow quantity ratio of discharge quantity of the main agent A liquid and the reaction agent B liquid to be discharged from pipelines A, B. Plural filling liquids, which are joined for mixture inside of the fill-in port 3 and of which solidification time is different from each other, are filled from the plural fill-in ports 3 to the ground. The main agent A liquid and the reaction agent B liquid are respectively fed by pumps PA, PB, and the flow quantity is controlled by pumps PA', PB' to change the liquid feeding ratio of the A, B liquids. Ground can be thereby solidified quickly and easily, and the gelation time of the filling liquids, of which gelation time is different from each other, can be changed without generating time lag.
