PROBLEM TO BE SOLVED: To provide an injection device and method into a ground through which a grouting liquid is injected into the ground through an injection pipe line installed in the ground to solidify the ground and can be always injected in a preliminarily determined specified delivery quantity, especially regardless of the pressure variation of the injection side for the injection material into the ground or the pressure change in the ground of the outlet side. SOLUTION: In the present injection device and method into ground to solidify the ground in which a grouting liquid is injected into a ground through injection pipe lines 19 installed in the ground to solidify the ground, a grouting liquid is fed into the injection pipe line through a flow rate control valve A, a distribution valve B, or through a combination system of the flow rate control valve and the distribution valve to inject it into the ground. Further, an injection liquid return system RS is provided in the above device to constitute it.
