CASE
Mud Cake Inhibitor is mainly composed of components such as organic polymers, diffusing agents, penetrating agents, dispersing agents, and anti-adhesion agents.
RSE is a modified high polymer that forms a gel-like substance soluble in water, produced by blending multiple covalently bonded polymer compounds.
The Shield Tunneling Backfill Grouting Monitoring System
It is mainly composed of the WGPR wireless ground penetrating radar (GPR) host system, arc-shaped rotating bracket + sprocket-driven scanning system, tunnel-specific base and mobile phone/tablet transmission terminal.
The segment fixing pile consists of a steel structure cylinder that houses a bladder. The steel structure cylinder is screwed into the grouting hole drilled into the segment. By injecting double-liquid grout into the steel structure cylinder, the internal bladder is squeezed out into the gap between the segment and the surrounding rock.
Cutterhead Anti-Mud Cake Coating Technology
The anti-mud cake cutterhead coating is a highly crystalline polymer with a low friction coefficient, low molecular polarity, low surface energy, and strong anti-adhesion properties. The coating solution is atomized using high-pressure air and uniformly sprayed onto the cutterhead panel at normal temperature, significantly reducing the probability of mud cake formation on the cutterhead.
Mud cake Removal Snake Robot is a special robot designed for cleaning mud cakes inside equipment such as TBM. It is generally composed of Mechanical body,Drive system,Sensing system,Cleaning system,Control system and Auxiliary system.
