This integrated grouting plant is specifically designed for shield/TBM tunnel segment lining. It combines a high-speed grouting tank, a grout storage and mixing tank, and a high-pressure grouting pump into one unit. During tunnel excavation, it prepares cement/bentonite grout to fill the annular gap (annular gap) between the lining segments and the surrounding rock.
A cement bentonite grout mixing plant is a specialized system designed to produce homogeneous, stable slurries used primarily in geotechnical and civil engineering applications such as: Slurry walls (diaphragm walls), groundwater cutoff, tunneling and shaft sealing, landfill containment barriers, and soil nailing and ground improvement. Working Principle: Premixing Stage: Bentonite and water are thoroughly dispersed under low-speed stirring to form a colloidal solution. Main Mixing Stage: Cement and additives are added, and homogeneous mixing is achieved through high-speed shear mixing. Transportation and Storage: The mixed slurry is transported to the construction site via a pumping system or temporarily stored in mixing tanks to maintain its fluidity.
