1. Introduction

Marine dredging is an important job in port building, waterway cleaning, and coastal projects. As more projects move offshore and into wet areas, machine stability becomes crucial for safety and work efficiency.

In water work, excavators often face problems such as waves, water flow, and soft ground under the sea. These factors can easily make the machine unstable and reduce working accuracy.

To solve this problem, we use a spud pole system. A simple but highly effective support tool. The spud pole goes deep into the seabed and holds the machine in place. This helps the excavator stay stable while working on water.

In this case, the team used a SANY amphibious excavator with a spud pole system for a marine dredging project. The machine worked in offshore water conditions and finished the job smoothly with good stability and high efficiency.

2. Project Background and Working Conditions

The project team placed the project in a coastal area. Workers needed dredging to remove sand and mud from the seabed. The goal was to keep the water channel deep enough for safe movement of boats.

The working conditions were not easy:

  • The machine worked on water surface
  • Waves and water flow affected stability
  • The seabed was soft and easy to sink
  • The work needed continuous and accurate digging

SANY Amphibious Excavator Performs Dredging Operations at Sea

Without a good support system, the machine would move too much and lose accuracy. So we needed a stable fixing method.

3. Engineering Solution by RIVER

To solve the stability problem, RIVER provided a simple and strong solution for the excavator.

The machine had four 8-meter-long spud poles. These poles are strong metal supports that go deep into the seabed and hold the machine firmly.

System Details

  • Machine: SANY amphibious excavator
  • Support system: 4 spud poles
  • Length of each pole: 8 meters
  • Control method: Hydraulic system

SANY Amphibious Excavator Is Equipped with Four Positioning Stakes

How It Works

The working process is simple:

  1. The excavator moves to the working position
  2. The spud poles go down into the seabed
  3. The hydraulic system locks the machine in place
  4. The excavator starts dredging work
  5. After finishing, the poles are lifted and the machine moves to next area

This system makes the machine stand still like it is “fixed on the ground,” even though it is working on water.

4. Work Performance and Results

After using the spud pole system, the excavator became much more stable. Even with waves and water movement, the machine stayed in a fixed position.

The operator could control the bucket more easily and do the dredging work with better accuracy.

Main Results

The project showed clear improvements:

  • The machine stayed stable during water work
  • Dredging became more accurate and smooth
  • Less time was needed to adjust machine position
  • Work continued without long stops
  • Safety level was improved in offshore work

The spud pole system made the whole dredging process easier, safer, and more efficient.

5. Advantages of Spud Pole System

This project shows that the spud pole system has many clear benefits in marine work:

  • Better Stability : The poles fix the machine into the seabed and reduce movement from waves.
  • Higher Accuracy : A stable machine can dig more precisely and reach the correct depth.
  • Higher Efficiency : Less movement means less time wasted on repositioning.
  • Safer Work : A stable platform reduces risks in water environments.

6. Other Application Areas

The spud pole system is not only used in marine dredging. It can also be used in many other water and soft ground projects:

  • River Dredging : Used to clean rivers and keep water channels clear.
  • Wetland Work : Helps machines stay stable in soft and muddy ground.
  • Port Construction : Used in harbor deepening and expansion projects.
  • Floating Work Platforms : Supports machines during lifting and installation jobs on water.

Application of Positioning Pile System in Water Engineering

RIVER can design different types of spud pole systems based on customer needs. We also provide different undercarriage solutions to improve machine stability and working performance.

7. Conclusion

This case clearly shows how a spud pole system helps a SANY excavator work better in marine dredging projects.

By fixing the machine into the seabed, the system gives strong stability, better accuracy, and safer working conditions.

As more construction projects move into water areas around the world, the need for spud pole systems will continue to grow.

With strong design skills and extensive experience, RIVER delivers simple, effective solutions. These solutions support amphibious work, marine dredging, and other complex water projects.
