PROBLEM TO BE SOLVED: To provide an injection control method of the ground, a device, and a ground injection construction method for controlling injection by collectively monitoring an injection state by displaying the injection state from injection liquid sending systems on an image screen when injecting a ground injection liquid into a plurality of injection points in the ground through a plurality of injection liquid sending systems from an injection liquid pressurizing part. SOLUTION: This device has a centralized control device X1 and an injection monitoring board X2 connected to this device, and when injecting the ground injection liquid into the plurality of injection points 5a in the ground through the plurality of injection liquid sending systems S, S, etc., S having respectively a branch valve 11 and flow rate-pressure detectors f and p from the injection liquid pressurizing part Y, a flow rate and pressure of the injection liquid detected by the flow rate- pressure detectors f and p and/or a data signal of an integral injection quantity are inputted to the centralized control device X1, the data signal inputted to the centralized control device X1 is displayed on the image screen of the injection monitoring board X2, and the injection state from the injection liquid sending systems S is collectively monitored on the image screen on the basis of information on these data to control the injection.
