Abstract

PURPOSE: To automatically inject the cement milk with high precision by lifting a processor after the elapse of prearranged time after the commencement of injection in the cement milk injection device for weak ground improvement.
CONSTITUTION: When the injection device is started, initial injection volume of the cement milk, i.e., an inclination angle of hydraulic pump is set manually. Next, if a pullout starting switch is closed "unload" on the hydraulic pump is reset, injecting the above-mentioned manually set cement milk for a prearranged period of time. Then, past the prearranged period of time, the injection device begins to be pulled out at a pullout speed memorized inside a memory unit and, at the same time, the cement milk is injected at a flow rate converted based on an actual pullout speed. When injection is terminated, the hydraulic pump is set at "unload", stopping cement milk feed.
