A ground treatment apparatus comprises a support device, injection elements, a fluid providing device that is fluidically connected to the injection elements, a drive device by which the injection elements are on the one hand lowerable and raisable in relation to the support device and on the other movable along a working direction of the ground treatment apparatus. The injection elements are insertable into the ground by being lowered in order to inject fluid into the ground in a treatment region, wherein the injection elements remain stationary during engagement in the ground in the treatment region, with relative movement in relation to the support device that is moved in the working direction, wherein the injection elements are raisable after the injection of fluid and are movable in the working direction in relation to the support device, wherein, on being lowered again, the injection elements are insertable into the ground in a further treatment region that is downstream of the first-mentioned treatment region, as seen in the working direction.
