Grouting through small pipes is a measure for the support of shallow-buried, excavated tunnels. After excavating in soft, fractured stratajiWhen the surrounding rock is prone to collapse, or when installing pre-support anchor bolts is difficult, or when the cross-section of the structure is large, pre-support small-diameter pipe jacking should be adopted. Pre-support small-diameter pipe jacking must be used in conjunction with steel arch supports. When conditions permit, pre-support grouting reinforcement can also be carried out on the ground; when there is a pilot tunnel, radial grouting reinforcement around the tunnel can also be performed within the pilot tunnel.
