Project Background and Project Overview

This project is a key urban water conservancy project for public welfare. Its core task is to carry out comprehensive dredging and desilting of the city's inland rivers, aiming to effectively widen and deepen the river cross-sections, significantly enhance the water flow capacity, thereby comprehensively improving regional flood control and drainage standards as well as waterway navigation conditions, providing solid support for urban ecological environment improvement and economic development.

However, the implementation conditions of this project are extremely challenging. The river where the project is located features narrow channels, numerous bends, and significant variations in water depth, with complex underwater terrain. Traditional large-scale dredging equipment struggles to operate effectively, placing stringent demands on equipment draft, maneuverability, and operational precision. Before the project commenced, the client’s biggest challenge was how to achieve efficient dredging within limited space while ensuring that the dredged sediment could be transported over long distances to designated disposal sites, avoiding secondary pollution or increased transportation costs.

To precisely meet the project requirements, Yake customized a professional cutter suction dredger with a flow rate of 1200 cubic meters per hour. This equipment was designed with full consideration of the site's complex working conditions, combining an advanced all-hydraulic drive system with a mature cutter suction operation principle, offering the following core technical advantages:

Firstly, the vessel adopts a shallow-draft design, ensuring free movement and operation even in rivers with fluctuating water levels and relatively shallow depths, demonstrating excellent adaptability. Secondly, its powerful hydraulic-driven cutter head can vigorously cut and stir underwater silt and hard soil layers, guaranteeing thorough excavation without leaving any dead corners. The suction system boasts strong power, enabling direct long-distance transport of the excavated slurry through pipelines up to 1000 meters away, truly achieving integrated “suction and discharge” functionality, eliminating intermediate transfer stages, greatly reducing environmental impact during construction, and effectively saving substantial secondary transportation costs.

In addition, the equipment’s control system is precise and responsive, capable of adjusting operating parameters in real-time according to actual water depth and sediment thickness, ensuring accurate control of dredging depth—meeting engineering design requirements while avoiding resource waste caused by over-excavation. The entire equipment set features high integration and excellent automation, allowing flexible turning and positioning even in confined waters, perfectly solving construction challenges under complex conditions.

Project Implementation Period

Thanks to the equipment’s outstanding performance and efficient operational capabilities, the project team organized construction scientifically, ensuring smooth progress throughout the entire project. Ultimately, all dredging tasks were completed 15 days ahead of schedule, delivering the project earlier than planned and showcasing both the high efficiency of Yake equipment and the high standard of project execution.

Application Results and Benefit Analysis

The deployment of Yake’s dredging vessel successfully achieved all the project’s predefined core objectives, yielding significant engineering benefits:

1. Qualitative Improvement in Flood Control and Navigation Capacity: After completion, the river’s flood-carrying cross-section was effectively expanded, increasing flood-carrying capacity by 40% and greatly enhancing the city’s ability to withstand floods, while navigation conditions were also thoroughly improved.

2. Significant Increase in Production Efficiency: The equipment maintained a stable daily dredging output of 1,500–1,800 cubic meters, with overall operational efficiency 25% higher than conventional industry equipment, realizing high productivity and a fast-paced construction rhythm.

3. Remarkable Optimization of Operating Costs: The application of long-distance pipeline transport technology eliminated the need for traditional mud barge transfers, directly reducing fuel, labor, and equipment wear-and-tear costs.

4. Strong Assurance of Equipment Stability: With its meticulously designed structure and highly durable key components, the equipment has demonstrated continuous operation for over 90% of the time, featuring an extremely low failure rate, ensuring round-the-clock, uninterrupted project progress and effectively shortening the overall construction period.

Customer Feedback

The successful completion of the project and its outstanding results have earned high recognition and unanimous praise from local government authorities and the project owner. Customers specifically noted that Yake’s dredging vessel not only perfectly adapted to the site’s complex construction conditions but also exceeded expectations with its high efficiency, stability, and energy-saving performance. This equipment not only efficiently resolved the persistent issue of sediment buildup in the city’s inland rivers but also created tremendous value for customers thanks to its excellent cost-effectiveness and reliability. This collaboration fully demonstrates Yake’s professional expertise and technical level in the field of dredging, establishing a solid foundation of trust between both parties, with anticipation for deeper cooperation in more areas in the future.
