BORED PILE SINGLE CUT CLEANING BUCKET

---

Overview

The Bored Pile Single Cut Cleaning Bucket is a precision-engineered drilling tool designed to deliver a clean, level, and debris-free borehole bottom before concrete pouring. It is an essential part of the foundation construction process, used after drilling with augers or core barrels to remove loose soil, gravel, and slurry residues. Built for accuracy, durability, and compatibility with a wide range of piling rigs, this bucket ensures the highest bearing strength and long-term stability for deep foundations.

Manufactured under 3GEN Export’s OEM standards, the BORED PILE SINGLE CUT CLEANING BUCKEToffers exceptional performance in both dry and slurry-supported boreholes. Its strong steel body, advanced cutting mechanism, and automatic closing system make it a preferred tool for contractors using Bauer, Soilmec, Liebherr, Junttan, Casagrande, ABI (Banut & Delmag), XCMG, SANY, Woltman, Mait, TYSIM, and Fangyuan piling rigs.

Each bucket is manufactured to exact dimensional tolerances and tested for load stability, ensuring reliable operation in soil layers ranging from cohesive clay to dense sand and weathered rock.

Function and Application

The BORED PILE SINGLE CUT CLEANING BUCKET serves a singular but critical purpose: cleaning the borehole bottom prior to concreting. After the drilling process is complete, fine soil, slurry, and rock fragments often remain at the base. These unwanted materials can compromise the concrete-to-soil bond and reduce load-bearing capacity.

When this bucket is lowered into the borehole and rotated, the cutting edge scrapes and collects all residual debris, creating a smooth and solid surface. The flap doors close automatically as the bucket is lifted, securely trapping the collected material. This ensures minimal spillage and efficient discharge at the surface.

Applications include:

• Bridge and viaduct foundations requiring deep, stable piles

• High-rise building foundations where structural reliability is vital

• Ports, marine, and offshore piling projects

• Wind turbine bases in hard or mixed soil conditions

• Infrastructure and industrial foundation works

The BORED PILE SINGLE CUT CLEANING BUCKET is indispensable for projects where precision and stability define success.

Design and Construction Features

1. Single-Cut Bottom Design

The defining feature of this bucket is its single-cut structure , a heavy-duty bottom plate equipped with sharp, replaceable blades. As the bucket rotates, these blades efficiently scrape off the last layers of sediment and loose materials at the borehole base. The simple mechanical layout guarantees reliability with fewer moving parts, reducing maintenance frequency.

2. Spring-Loaded Bottom Flaps

The spring-loaded flap mechanism automatically opens during soil collection and closes when the bucket is lifted. This self-sealing system prevents the loss of collected material during lifting and transportation, providing a cleaner and faster operation cycle.

3. High-Tensile Steel Cylinder Body

Fabricated from heat-treated alloy steel, the cylinder body withstands the extreme torque and vertical pressure generated by heavy drilling rigs. Its reinforced ribs and balanced geometry ensure stability and uniform stress distribution, even under continuous high-load conditions.

4. Replaceable Cutting Teeth and Wear Pads

Each tooth and wear segment is manufactured with tungsten-carbide tips, providing long-lasting sharpness and resistance to abrasion. The modular design allows quick replacement of teeth and pads, reducing downtime during maintenance.

5. Kelly Box Interface

The upper connection features a standard Kelly box (available in 130 mm, 200 mm, and 250 mm square sizes) for perfect fit with all major rotary drilling rigs. This universal interface simplifies equipment changeovers and ensures torque transfer efficiency.

6. Surface Treatment and Corrosion Protection

Every BORED PILE SINGLE CUT CLEANING BUCKET is coated with industrial-grade epoxy paint, ensuring strong resistance to corrosion, slurry, and humidity. The high-gloss yellow or green coating visible in the images also improves visibility and safety on construction sites.

How It Works

1. Lowering into the Borehole
   The bucket is attached to the Kelly bar and lowered to the borehole’s base. The spring-loaded flaps open automatically due to hydraulic pressure and gravity.

2. Cutting and Collecting Phase
   As the rotary drive activates, the single-cut edge scrapes and collects residual debris, sand, and fine particles. The bucket fills evenly without disturbing the surrounding wall.

3. Lifting and Sealing
   During lifting, the flap closes tightly, trapping all material inside. This prevents debris loss and ensures the borehole bottom remains clean and undisturbed.

4. Discharging at the Surface
   Once above ground, the flap opens, allowing rapid and complete soil discharge. The process can be repeated until the borehole is perfectly clean and ready for concreting.

This efficient operation cycle allows contractors to maintain continuous workflow with minimal downtime.
