Company Profile

Blowing sand to fill the sea refers to using the pump of a dredger to blow sand and water from the seabed outside the circle into the target circle. When seawater flows out of the circle, the sand stays inside the circle, and gradually the sea surface inside the circle is filled with continuously blown sand into land. In this process, the dredger plays an important role.

The cutter suction dredger is a commonly used type of dredger, which uses a rotating cutter to loosen the sediment on the seabed, and then pumps it in and transports it to a designated location through pipelines. This type of dredger has the advantages of high dredging efficiency and long transportation distance, and is therefore widely used in sand reclamation projects.

China has made significant achievements in the field of dredgers, with the ability to independently design and manufacture large cutter suction dredgers. Among them, "Tiankun" is the largest self-propelled cutter suction dredger independently developed by China in Asia, with a total length of 140.5 meters, a width of 27.8 meters, a depth of 9 meters, a maximum draft of 6.5 meters, a total installed power of 25800 kilowatts, a maximum dredging depth of 35 meters, a maximum sediment transport distance of 15 kilometers, and a dredging capacity of 6000 cubic meters per hour. It has a design lifespan of 30 years and can be used for sand blowing and reclamation work in any sea area.

In addition, China has also built world leading cutter suction dredgers such as the "New Haixu", which have reached international advanced levels in technology and performance, providing strong support for China's marine development and island construction.

We have been engaged in the manufacturing of dredgers for over 20 years, and we believe that we are the most professional. Our main products include: cutter suction dredgers, chain bucket sand mining ships, water purification ships, water transport ships, gold mining ships, sea sand desalination equipment, etc!
Our profession is extracting sand from water, extracting various minerals, long-distance transportation in water, and cleaning weeds on the water surface!

The following are some key points regarding the design, installation, and commissioning of marine dredging equipment cutter suction dredgers:

**Design:**

-The design of ship structure should consider the complexity and harshness of the marine environment, and have sufficient strength and stability.
-The design of the cutter system should adapt to different seabed geological conditions to ensure efficient excavation capabilities.
-The diameter of the mud conveying system and the power of the pump should be reasonably matched to achieve smooth sediment transportation.
-The design of the power system should meet the power requirements of dredging operations while considering fuel economy.

**Installation:**

-During the installation process, it is necessary to strictly follow the design drawings and process requirements to ensure accurate and firm installation of each component.
-Fine installation and debugging of key components such as winches and mud pumps to ensure their normal operation.
-Install various sensors and monitoring equipment to monitor the real-time operation status of the dredger.

**Debugging:**

-Debug the power system to ensure smooth operation of the engine and other equipment, and ensure that the output power meets the requirements.
-Gradually debug the cutter system and check the rotation and excavation effect of the cutter.
-Test the mud conveying system and observe whether the flow rate, pressure, and other parameters of the mud are normal.
-Conduct overall joint debugging, simulate actual operating conditions, comprehensively evaluate and optimize the performance of the dredger, and ensure its safe and efficient operation.

Throughout the entire process, close cooperation between professional engineers, technicians, and skilled workers is required to strictly control the quality of each link, in order to create a high-performance cutter suction dredger. At the same time, continuous technological innovation and improvement should be carried out to adapt to the constantly changing needs of marine dredging.

Chinese made dredgers not only occupy an important position in the domestic market, but also have been widely recognized in the international market. At present, it has been sold to 68 countries and regions worldwide and has achieved success. These dredgers are widely used in deep-sea sand mining, coastal deepwater port channel dredging, reclamation, and coastal maintenance projects, making important contributions to China's marine engineering and infrastructure construction. We can tailor the most cost-effective dredging equipment for you based on your construction environment and work requirements!

 

Detailed Photos

 

          A cutter suction dredger is a dredging tool that uses a rotating cutter to loosen the soil on the riverbed or seabed, mixes it with cement to form mud, and then sucks the mud into the pump body through a suction pipe and sends it to the discharge area. It is mainly used for dredging in inland lake areas and coastal ports, suitable for excavating soil such as sand, sandy loam, and silt. During the construction of the cutter suction dredger, the dredging, transportation, and unloading processes can be completed continuously in one go, resulting in high production efficiency.
The main structure of a cutter suction dredger includes the hull, cutter, suction pipe, pump body, and discharge pipe. The cutter is a key component of a cutter suction dredger, usually installed at the bow or side of the ship. By rotating the cutter, the sediment at the bottom of the water is crushed and mixed with water to form mud. The suction pipe is used to suck mud into the pump body, which transports the mud to the discharge area through the discharge pipe.

 

 
 

The construction process of a cutter suction dredger is generally as follows:
1. Construction preparation: including the formulation of construction plans, survey of construction areas, equipment inspection and commissioning, etc., then positioning the ship and accurately positioning the cutter suction dredger in the construction area. According to the wind and flow conditions, set up the windward and upstream anchors in order to stabilize the ship's hull.
2. Lowering the cutter bridge: Lower the cutter bridge to the designated cutter position for excavation.
3. Soil conveying: The soil crushed by the cutter is transported to the designated mud receiving area through a high-power centrifugal mud pump and a discharge pipeline.
4. Construction monitoring: Real time monitoring of excavation depth, instantaneous water level, cross-sectional view of excavation trench or underwater three-dimensional map and other data to ensure construction quality and safety.
5. Moving ship position: According to construction needs, move the ship to the next construction area by retracting and releasing anchor cables and adjusting the position of the winch.
The specific construction process may be adjusted appropriately based on engineering requirements, soil quality, hydrology, and other factors. topic
