Abstract
PURPOSE: To inject carbonic acid gases always at the preliminarily fixed ratio against a water glass quantity and obtain uniform solid body, by mounting a pressure sensing apparatus between a carbonic acid gas tank a multiple tube.
CONSTITUTION: Carbonic acid gases are sent by pressure from the tank 1 controlled by a reducing valve 2 to the fixed pressure level. The pressure sensing apparatus A senses the changing pressure of the ground 4, and the approximate quantity of the carbonic acid gases are sent by pressure in conformity with the ground pressure. On the other hand, water glass solutions are sent to the ground 4 from a tank 5 through a reducing valve 6, a rotation adjusted pump 7 and a flow meter 8. The water glass solutions and the carbonic acid gases are joined at the upper part of the injection tube or at the end part of the injection tube consisting of the multiple tube 9, and poured into the ground 4. With such an arrangement, the fixed ratio between the water glass solutions and the carbonic acid gases is always maintained in spite of the changes in the ground pressure, and the uniform solid body can be obtained.
