Metro Station Construction Deep Excavation Project

2026-07-21

Project Overview:

A critical infrastructure project involving the construction of a new Metro Station in a densely populated urban area required the execution of a 1.5-meter thick, 55-meter deep diaphragm wall. The geological conditions consisted of mixed layers of hard sandstone and dense gravel, demanding high-performance equipment.

The Challenge:

The project faced significant hurdles due to the depth of the excavation and the abrasive nature of the soil. The primary issue was the rapid wear and tear on standard slurry pumps, which led to frequent downtime for maintenance and replacement. The client required a heavy-duty slurry pump capable of handling high specific gravity slurries with large solid particles without clogging or suffering from premature impeller failure.

The Solution:

APIE FOUNDATION EQUIPMENT (CHINA) LIMITED supplied the client with our specialized Trench Cutter Slurry Pump, specifically engineered for diaphragm walling projects. Key features included:

  • High-Chrome Alloy Impeller: Designed for extreme abrasion resistance, extending the service life by 300% compared to standard pumps.
  • Optimized Hydraulic Design: Ensures smooth flow of high-density slurry, preventing blockages during the trench cutting process.
  • Robust Seal System: Utilized an advanced mechanical seal flushing system to protect the pump shaft from abrasive slurry infiltration.

The Result:

The APIE trench cutter pump operated continuously for 450 hours without a single mechanical failure. The contractor reported a 25% increase in drilling efficiency due to the consistent slurry circulation speed. The project was completed two weeks ahead of schedule, significantly reducing rental and labor costs.

Client Feedback:

*“The reliability of APIE’s slurry pump was outstanding. In previous projects, we struggled with pump durability in these hard rock conditions. The APIE pump handled the abrasive slurry effortlessly, allowing us to focus on the trenching speed rather than equipment maintenance.”*
