Introduction

In large-area shallow water dredging, beach restoration and large-scale fine sand mining projects, traditional small jet suction dredgers have insufficient output and low construction efficiency, which cannot meet the production demands of large-scale projects. Although the cutter suction dredger has high output, its rotary cutter head will cause large-scale disturbance to the riverbed and seawater bottom, resulting in a sharp increase in water turbidity, which cannot meet the environmental protection requirements of scenic water areas, coastal ecological zones and island tourist waters.
The 16 inch jet suction dredger is a large-flow high-capacity environmentally friendly dredging equipment optimized and upgraded for large-scale shallow water working conditions. It inherits all the advantages of traditional jet dredgers such as zero bottom damage, low turbidity and simple maintenance, and greatly upgrades the pump flow, jet flushing power and long-distance conveying capacity. It perfectly balances high production efficiency and ecological environmental protection, and has become the preferred professional equipment for large-area river basin sand mining, coastal beach nourishment, lake large-scale desilting and environmentally sensitive water area dredging projects.

Working Principle & Core Advantages

1. High-Pressure Water Jet Loosening Technology

The dredger is equipped with a multi-nozzle high-pressure jet flushing system. Multiple groups of high-speed water nozzles are arranged around the suction inlet, which can form a three-dimensional water flushing network underwater. The high-speed water jet accurately scours and loosens surface fine sand, floating silt and loose sediment layers. The whole process only acts on the floating sediment on the water bottom, will not damage the stable original riverbed and seabed substrate, will not cause large-area sediment rolling and turbidity diffusion, and fully complies with international ecological dredging environmental protection standards.

2. Large-Flow 16-Inch Professional Sand Pump System

Matched with Ocean Pump customized 16-inch super large-flow sand pump, the pump body is optimized for high-flow and high-concentration fine sand conveying. The internal flow channel is widened and streamlined to reduce conveying resistance. The high-chrome alloy wet parts can resist long-term high-flow sediment scouring, avoiding rapid wear and efficiency attenuation. The overall pumping capacity is far higher than that of 8-inch and 10-inch jet dredgers, realizing super-high hourly sand output and greatly improving project construction progress.

3. Ultra-Low Ecological Disturbance & Environmental Protection Performance

Different from cutter suction dredgers that rely on rotary cutting heads to crush sediment, the 16-inch jet suction dredger has no mechanical cutting structure. It completely relies on water power to loosen and absorb sediment. The construction process is stable and gentle, with small turbidity fluctuation and no damage to aquatic plant roots, benthic organisms and riverbed foundation. It is especially suitable for environmentally restricted areas such as coastal protection zones, island scenic waters, fishery breeding waters and urban ecological lakes.

4. Simple Structure, Stable Operation and Low Failure Rate

The equipment structure is simple and scientific, without complex hydraulic cutting system and multi-stage transmission structure. The vulnerable parts are few, and the daily operation and maintenance difficulty is extremely low. The whole machine can operate stably for a long time in fine sand and silt working conditions, with extremely low accidental shutdown rate. It can realize 24-hour continuous uninterrupted construction, providing stable output guarantee for large-scale long-term projects.
