Brief Introduction
Amphibious dredgers, due to their unique amphibious design, demonstrate significant efficiency in specific operational scenarios. Their operational efficiency is mainly reflected in the following aspects:
**Efficiency Comparison:** Compared to traditional manual cleaning, the efficiency improvement of amphibious dredgers is extremely significant. For example, in the river cleaning operation in Juegang Street,
Rudong County, the operational efficiency of one multi-functional amphibious work vehicle (boat) is equivalent to that of 25 manual laborers,
not only greatly increasing the cleaning speed but also solving the problems associated with manual cleaning.
**Specific Operational Capabilities:** Amphibious dredgers typically possess multiple functions, such as dredging, aquatic weed cutting, and blue-green algae removal, with a dredging productivity of 30-70 cubic meters per hour.
Some advanced models (such as the "Water King" amphibious dredger) completed 15,000 cubic meters of dredging in just 25 days in the Taohuatan Park dredging project, demonstrating highly efficient operational capabilities.
Advantages in Applicable Scenarios
In areas where traditional dredgers cannot access, such as shallow water and swamps, amphibious dredgers, with their mobility (e.g., tracked + floating design), can freely switch between operating environments, completing dredging work in complex terrain without auxiliary equipment.
For example, the "New Mud King" can move and operate under extreme conditions, adapting to waters with large level differences or high corrosiveness.
Technical Features Supporting Efficiency
Some models are equipped with a pump bucket device, which can increase the mud concentration and transport it up to 500 meters (up to 1000 meters with pressurization) through the mud discharge pipeline. Simultaneously, the cutting impeller can handle soil containing plant roots and stems, further ensuring the stability of continuous operation.
