Performance and grouting parameters of new advanced reinforcement materials for underground tunnels with dense fine sand layers

In order to mitigate the impact of advanced grouting reinforcement on the underground environment, it's necessary to employ low-pressure slow injection for grouting. The dense fine sand layer exhibits a tight structure and high clay content. Consequently, under low grouting pressure, the diffusion r...
