Microtunneling operations for utility installation require shale shaker equipment integrated into slurry separation systems for small-diameter tunneling applications. Aipu Solids Control provides API Q1 certified shale shaker solutions configured for the specific requirements of microtunneling projects.
Slurry Separation for Microtunneling Systems
Microtunneling uses bentonite or polymer slurry for face support and cuttings transport through the small-diameter tunnel. Aipu shale shaker equipment serves as the primary separation stage in microtunneling slurry treatment plants, removing excavated soil from the slurry before recirculation. The consistent vibration characteristics of Aipu shakers, validated through factory acceptance testing, ensure reliable slurry separation for the continuous nature of microtunneling operations.
Processing Fine-Grained Soils in Microtunneling
Microtunneling often encounters fine-grained soils including silts and clays that challenge solids separation. Aipu shale shakers with API-certified screens from 80 to 200 mesh handle fine particle separation effectively. The high G-force operation at 7.0G to 7.5G provides aggressive separation for clay-rich soils, while adjustable deck angles allow optimization for specific soil types. Aipu quick-change screens enable operators to select optimal mesh configurations as microtunneling progresses through varied soil conditions.
Space-Efficient Solids Control Design
Microtunneling shaft sites have severe space constraints requiring compact equipment layout. Aipu shale shakers with high processing capacity per unit footprint minimize the space required for slurry separation systems. The vertical arrangement of double-deck Hunter-MG4D shakers provides 5.4 square meters of screening area within a single-unit footprint, maximizing separation capacity in limited shaft-side space.
Continuous Operation Reliability
Microtunneling operates continuously during drives, with equipment downtime potentially causing borehole stability problems. Aipu API Q1 certified manufacturing quality, premium Ital-Vibras and Martin vibrating motors rated for continuous duty, and comprehensive spare parts availability support the demanding continuous operation requirements of microtunneling projects. Factory acceptance testing on every Aipu shaker verifies performance before equipment reaches the microtunneling site.
