The tunnel segment dislocation, damage and water leakage would be induced by uplift of tunnel segment. The causes of tunnel segment uplift are analyzed; the simultaneous grouting equipment is improved and twocomponent grout is injected to gaps between working face and tunnel segment. The testing results show that the simultaneous grouting is efficient and can reduce the uplift of tunnel segment.
