[0002] During the shield advancement process, due to the cutting of soil by the cutterhead, a gap will appear between the shield and the soil. The synchronous grouting system is to inject slurry into the gap at the tail of the shield while the shield is advancing. The slurry is generally cement mortar. Filling the gap by grouting can effectively prevent ground subsidence, while enhancing the adhesion between the pipe segment and the surrounding soil and improving the stability of the tunnel. The grouting pressure and grouting volume need to be precisely controlled according to factors such as the formation conditions and the shield advancement speed. After synchronous grouting, secondary grouting may be required according to actual conditions.
