The Barrel Reamer is a powerful, large-diameter hole-enlarging tool specially designed for soft soil, loose formations, and complex geological conditions.
Precision-manufactured from high-strength alloy steel, this product features a unique working mechanism that combines rolling compaction with cutting. It effectively enlarges the borehole diameter, significantly improves reaming efficiency, and compacts the borehole wall simultaneously.
Its streamlined, barrel-shaped design not only ensures efficient spoil removal and mud circulation but also maintains exceptional borehole stability, providing a smooth and safe tunnel environment for subsequent pipe pullback. The overall structure is highly robust and wear-resistant, delivering outstanding impact resistance and a prolonged service life.
Features
-
High-Efficiency Reaming: A scientifically engineered tooth layout and streamlined body significantly accelerate the hole-forming process and reduce repetitive operational time.
-
Optimized for Soft Soil: Specially designed for soft soil conditions. It excels in clay, sand, backfill, and similar formations, providing excellent compaction and shaping effects.
-
Exceptional Borehole Stability: Exerts strong radial pressure on the borehole wall during operation, drastically minimizing the risk of collapse and ensuring a high-quality bore.
-
Robust, Durable, and Impact-Resistant: Welded from premium alloy steel to provide superior strength and wear resistance, easily handling complex and demanding construction environments.
-
Comprehensive Specifications & Customizable: Standard sizes range from Φ200mm to 2000mm to meet diverse diameter requirements. Custom dimensions are also available upon request.
-
Easy Installation & Wide Compatibility: Offers flexible connection options to ensure compatibility with mainstream drilling rigs on the market.
