Abstract
PURPOSE: To control the injection pressure and amount of a grout to prevent the settlement and hardening of the grout inside a pipe by comparing detection signals from injection pipe and return pipe with set signals and critical flow rate for calculation.
CONSTITUTION: The set signal of a pressure setter 22 is compared with detection signals from a pressure gauge 17 on the injection side and a pressure gauge 20 on the return side in a comparison and calculation controller 23. By the output signal of the controller 23, a servo mechanism 24 by which the flow rate of an injection pump 13 is controlled is driven. Then, the set signal of a flow setter 25, detection signals from the flow meters 18 and 19 on the injection and return sides, and signal from a viscometer 26 for preventing the settlement of grout, are compared with each other in a comparison and calculation controller 27, and by the output signal of the controller 27, the servo mechanism 30 of the flow controller 21 is controlled. On the other hand, the amount of grout injected (Q1-Q2) is recorded in an integrating meter 29.
