Key Terms
Soil-Bentonite Slurry
A Slurry Wall Technician specializes in installing soil-bentonite slurry walls, which serve as effective groundwater cut-off barriers in excavation projects. Proficient in mixing and maintaining bentonite slurry, they ensure soil stability and prevent water intrusion during trench excavation. Expertise in monitoring slurry density and viscosity is crucial for maintaining structural integrity and environmental compliance.
Bentonite Mixing
A Slurry wall technician specializing in Bentonite mixing ensures precise formulation and consistency of Bentonite slurry used in deep excavation support. Mastery in adjusting mixture ratios, monitoring slurry properties like viscosity and density, and maintaining equipment is crucial for preventing soil collapse during construction. Expertise in Bentonite slurry management directly impacts excavation stability, environmental safety, and project timeline adherence.
Slurry Density
Slurry wall technicians monitor and control slurry density to ensure optimal support during excavation processes, preventing soil collapse and water infiltration. Maintaining precise slurry density, typically between 1.15 and 1.30 specific gravity, is critical for effective pressure balance and structural integrity. Advanced density measurement tools and real-time data analysis enable technicians to adjust slurry composition, enhancing safety and project efficiency.
Trench Excavation
Slurry wall technicians specialize in trench excavation by creating reinforced barriers within deep soil using bentonite slurry to stabilize trench walls during construction. Precise control of slurry pressure and continuous monitoring ensure the trench remains intact, preventing collapses and groundwater ingress. Expertise in operating specialized excavation equipment and understanding soil mechanics is essential for maintaining trench integrity throughout the slurry wall construction process.
