One of the most significant challenges in building underground infrastructure and tunnels in urban environments is controlling the surface settlement caused by excavation. Any loosening and deformation of the surrounding ground will propagate upward, jeopardizing the safety of surfa…
Tunnel Pre-Support is the critical step in tunnel engineering for controlling ground stability and deformation. Whether utilizing long-distance Tunnel Roof Support Pipes for a pipe umbrella system or shorter Forepoling Pipes for localized reinforcement, the quality of construction d…
In complex geological formations—particularly soft ground, fractured rock, or water-bearing strata—tunnel excavation carries significant risks of face instability and excessive ground deformation. The Pipe Umbrella System stands as a highly effective pre-support technology, creati…
Tunneling through challenging geological formations—particularly soft ground, fractured rock, or areas with high groundwater—presents significant geotechnical risks. To ensure the safety of workers, the stability of the tunnel face, and the control of surface settlement, Pre-Suppo…
While the Grouting Pipe (Injection Pipe) provides the delivery mechanism, the ultimate success of any stabilization or sealing project lies in the proper execution of the grouting process and the quality of the materials used. Effective grout effectiveness evaluation and strict qual…
