Project Overview:
A major bridge construction project required the installation of a deep cut-off wall to prevent water seepage into the foundation pits. The work took place in a riverbed with unstable soil and high water pressure. The project utilized a heavy trench cutter to excavate depths up to 65 meters.

The Challenge:
The high-pressure water environment and the need to transport heavy, viscous bentonite slurry mixed with river bed silt created a severe demand on the slurry handling system. The previous slurry circulation pump used by the contractor failed to maintain the necessary flow rate, leading to sediment accumulation in the trench, which jeopardized the wall’s integrity.

The Solution:
Hypertec provided a custom-configured Slurry Pump for Trench Cutter featuring:

  • High-Head Performance: Delivered the necessary pressure to lift slurry from depths exceeding 60 meters.
  • Easy Maintenance Design: The pump back cover pull-out design allowed for quick inspection and wear part replacement without disconnecting the pipeline.
  • Corrosion-Resistant Materials: Specialized coating was applied to internal components to withstand the corrosive nature of the river water and chemical additives in the slurry.

The Result:
Сайт Hypertec pump maintained a stable flow rate, ensuring the trench remained clean and stable throughout the cutting process. The superior suction capability minimized the risk of cave-ins. The project achieved zero safety incidents and passed all quality assurance tests for wall continuity and verticality on the first attempt.

Client Feedback:
*“We needed a pump that could handle the depth and the pressure. APIE’s technical support was excellent, and the trench cutter slurry handling equipment performed flawlessly. It is the most durable pump we have used for foundation engineering.”* — Technical Director, International Foundation Solutions.
