Amphibious Multifunctional Dredger

"crawler + floating body" dual walking system, multi-mode dredging modules (bucket/cutter/suction cup), and mud treatment & transfer system, focusing on four tasks: inland waterway dredging, coastal shoal development, reclamation dredging, and emergency flood control. Aiming at the pain points of traditional dredgers such as "stranding in shallow water, inability to operate on land, single function", it realizes cross-scenario operations in "shoal-inland-coastal" through amphibious walking (land speed 3km/h, water speed 8km/h), quick switching of multi-functional devices (≤2 hours), and CCSB steel anti-corrosion structure (yield strength ≥235MPa). The daily dredging volume reaches 8000-12000m³, 50% more efficient than traditional single-function dredgers, providing a "full-scenario, multi-functional, high-efficiency" solution for multi-terrain dredging projects.

Core Advantages

Amphibious Operation, Full-scenario Adaptation

Dual-mode Walking System: Land use 4 sets of wide crawler walking devices (crawler width 1.2m, ground pressure ≤50kPa), which can move stably on muddy shoals and swamps, with a minimum turning radius of 8m; water navigation is realized through side floating bodies + propellers (equipped with 2 sets of 500kW diesel propellers, speed 8km/h), minimum working water depth 0.5m, avoiding stranding of traditional dredgers in shallow water;

Terrain Adaptive Adjustment: HAIDING SHIPYARD amphibious multifunctional dredger equipped with attitude sensor (accuracy ±0.5°), which can adjust crawler tension and floating body draft in real time, maintaining hull level in sloped shoals (slope ≤15°) or shallow water, ensuring dredging accuracy (dredging flatness error ≤0.3m).

Multi-functional Dredging Integration, High Operation Efficiency

Multi-mode Dredging Modules: Supports quick switching of 3 core devices — ① Hydraulic bucket (capacity 6-10m³, digging force 380kN, adapted to hard soil layer dredging); ② Cutter head (diameter 2.5-3.0m, speed 15-25r/min, adapted to sludge/sand layer); ③ Vacuum suction cup (suction ≥200kPa, adapted to fine particle mud cleaning). Modules are connected via standardized interfaces, switching time ≤2 hours, meeting different geological dredging needs;

Mud Treatment-Transfer Integration: HAIDING SHIPYARD amphibious multifunctional dredger equipped with 150m³/h mud pump (working pressure ≥1.2MPa) and three-stage mud purification system (desanding/desliming/dewatering), the solid content of purified mud is ≤10%, which can be directly transferred to muck ships via on-board conveyor belt (conveying distance ≤50m) or to shore yards via pipelines, reducing intermediate transfer links.

Anti-corrosion & Durability, Adapting to Complex Environments

CCSB Steel Structure: Hull, floating bodies, and dredging devices are welded with CCSB marine steel plates (thickness 12-20mm); key parts (crawler brackets, cutter shafts) are quenched and tempered with CCSB steel plates (hardness ≥200HB), with excellent seawater corrosion resistance and impact resistance (impact energy ≥27J at -20℃), adapting to fresh water, seawater, saline-alkali shoals and other multi-medium environments;

Harsh Environment Protection: HAIDING SHIPYARD amphibious multifunctional dredgers have IP65 protection grade, electrical system adopts waterproof sealing design, which can operate continuously in heavy rain and 6-level wind waves (wind speed ≤10.8m/s); equipped with automatic fire extinguishing system (gas fire extinguishing + sprinkler) and emergency drainage pump to ensure operation safety.

Modular Design, Convenient Operation & Maintenance

Core Components Modularization: Walking system (crawler drive unit), dredging devices (bucket/cutter), and mud pump adopt modular design, which can be disassembled and replaced as a whole in case of failure, with land maintenance time ≤6 hours and water emergency maintenance ≤12 hours;

Detailed Technical Parameters

Core Application Scenarios

Inland Waterway Dredging

Shallow Waterway Widening: In inland rivers of Yangtze River tributaries and Pearl River Delta (water depth 1-5m), use cutter + suction cup combination mode to remove sludge and domestic waste at the bottom of waterways; after dredging, waterway depth is increased to 3-6m, meeting navigation of 1000-ton cargo ships;

Wharf Berth Dredging: For inland wharf berths (water depth 2-8m), use bucket mode to clean hard soil layer siltation, ensuring berth water depth meets ship docking needs, with dredging flatness error ≤0.3m to avoid ship stranding.

Coastal Shoal Development

Shoal Reclamation: In coastal shoals of Bohai Bay and East China Sea (water depth 0.5-3m), HAIDING SHIPYARD amphibious multifunctional dredger uses cutter mode to dredge shoal sediment, and transport it to reclamation areas via mud pipelines; daily reclamation area can reach 5000-8000㎡, 40% more efficient than traditional dredger-fill ships;

Shoal Aquaculture Area Dredging: For coastal aquaculture areas (water depth 0.8-2m), use suction cup mode to clean aquaculture wastewater and residual bait siltation, purify water transparency to 1.5-2m, improve aquaculture environment, and avoid aquatic product losses caused by water deterioration.

Emergency Rescue

River Blockage & Flood Drainage: In inland river blockages caused by heavy rain (water depth 1-3m, containing branches and garbage), use bucket mode to clean blockages, and cooperate with mud pumps to drain stagnant water; daily flood drainage volume reaches 50000m³, quickly restoring river flood discharge capacity;

Coastal Post-disaster Dredging: After typhoons and storm surges, in coastal ports and wharves (water depth 2-6m), use "cutter + purification" mode to clean sediment siltation and pollutants; normal port operations can be restored in 3-5 days, reducing post-disaster losses.
